The original implementation (which was never merged) had a `<select>`
field for the switch, which offered accessibility issues. So I came up
with a very bad idea, which was emulating the look and feel of a select
field while making it more accessible for keyboard users.
This approach is inconvenient because we were using a bunch of ARIA
roles to do the same thing that can be done with a list of links, going
against the first rule of ARIA, which is:
> "Don’t use ARIA if you can achieve the same semantics with a native
> HTML element or attribute
Not only that, but the control was confusing for people using mobile
phones (select fields don't behave the same way), and we were using
*invalid* ARIA roles in this situation, leading Axe to report a critical
accessibility error:
```
aria-required-children: Certain ARIA roles must contain particular
children (critical)
https://dequeuniversity.com/rules/axe/4.10/aria-required-children?application=axeAPI
The following 1 node violate this rule:
Selector: ul[data-dropdown-menu="edw1i2-dropdown-menu"]
HTML: <ul class="dropdown menu" wnenu="edw1i2-dropdown-menu"
data-disable-hover="true" op="true" role="menubar">
Fix any of the following:
- Element has children which are not allowed: button[tabindex]
```
So, at least for now, we're using a simple list of links. We might style
it in the future if we find ways to make usability improvements, but,
for now, it does the job, and it does it better than the custom control
we were using.
We removed the link to this page in commit 83e8d6035 because poll
questions don't really make sense without a poll.
However, this page also contained information about successful
proposals, which might be interesting so administrators don't have to
navigate to the public area in order to find and create questions based
on successful proposals.
So we're keeping the part about successful proposals and linking it from
the proposals part of the admin area.
Note we're using translation keys like `successful_proposals_tab`, which
don't make sense anymore, for the successful proposals. We're doing so
because we've already got translations for these keys and, if we renamed
them, we'd lose the existing translations and our translators would have
to add them again.
Also note we're changing one poll question test a little bit so we
create the question from a successful proposal using the new page. There
are other tests checking how to create a question from the
admin/proposals#show action and other tests checking what happens when
accessing a successful proposal in the admin section, so we don't lose
any test coverage by changing an existing test instead of adding a new
one.
Finally, note that we've removing the `search` method in poll question
because we no longer use it. This currently makes the
`author_visible_name` database column useless; we aren't removing it
right now because we don't want to risk a possible data loss in a patch
release (we're about to release version 2.3.1), but we might remove it
in the future.
We had inconsistent indentation in many places. Now we're fixing them
and adding a linter to our CI so we don't accidentally introduce
inconsistent indentations again.
We only want to render the account link and login items in the header.
And we want only render the Multitenancy and Administrators sections in
the admin sidebar.
We include the administrators management so it's possible to give
permissions to other users to manage tenants.
In order to restrict access to other sections by typing the URL or
following a link, we're only enabling the rest of the routes when we
aren't in the multitenancy management mode.
Using a checkbox wasn't very intuitive because checkboxes are
checked/unchecked when clicked on even if there's an error in the
request. Usually, when checkboxes appear on a form, they don't send any
information to the server unless we click a button to send the form.
So we're using a switch instead of a checkbox, like we did to
enable/disable phases in commit 46d8bc4f0.
Note that, since we've got two switches that match the default
`dom_id(record) .toggle-switch` selector, we need to find a way to
differentiate them. We're adding the `form_class` option for that.
Also note that we're now using a separate action and removing the
JavaScript in the `update` action which assumed that AJAX requests to
this action were always related to updating the `visible_to_valuators`
attribute.
Just like it happened with proposals, the button to select/deselect an
investment wasn't very intuitive; for example, it wasn't obvious that
pressing a button saying "selected" would deselect the investment.
So we're using a switch control, like we do to enable/disable features
since commit fabe97e50.
Note that we're making the text of the switch smaller than in other
places because the text in the investments table it is also smaller
(we're using `font-size: inherit` for that purpose). That made the
button look weird because we were using rems instead of ems for the
width of the button, so we're adjusting that as well.
Also note we're changing the width of the switch to `6em` instead of
`6.25em` (which would be 100px if 1em is 16px). We're doing so because
we used 100 for the minimum width because it's a round number, so
now we're using another round number.
This way we'll be able to simplify it a little bit.
Note that the original partial didn't include the whole row and only
the cells. Since, most of the time, we include the whole row in
partials, we're slightly modifying the component.
The button to select/deselect a proposal wasn't very intuitive; for
example, it wasn't obvious that pressing a button saying "selected"
would deselect the proposal.
So we're using a switch control, like we do to enable/disable features
since commit fabe97e50.
Most existing Consul Democracy installations will have changed their
`config.i18n.available_locales` option so only a few locales are
available. In many cases, only one locale will be available. In these
cases, rendering a form that only offers one option is useless.
We've considered adding a text in this case mentioning that, in order to
enable more languages, they need to configure their
`config.i18n.available_locales`. However, we haven't done it for two
reasons.
First, if they've changed the available locales to just one, there's a
good chance they aren't interested at all in configuring the locales.
And, second, if there's only one available locale, administrators will
learn to ignore the "languages" link, so they won't realize that locales
can be configured if developers change the available locales. If we hide
the link, on the other hand, they will notice that locales can now be
configured once developers change the available locales.
Note we're still allowing access by entering the URL. This is harmless,
though, since people accessing it this way will see a form with only one
possible option and won't be able to modify anything.
Having a class named `Poll::Question::Answer` and another class named
`Poll::Answer` was so confusing that no developer working on the project
has ever been capable of remembering which is which for more than a few
seconds.
Furthermore, we're planning to add open answers to polls, and we might
add a reference from the `poll_answers` table to the
`poll_question_answers` table to property differentiate between open
answers and closed answers. Having yet another thing named answer would
be more than what our brains can handle (we know it because we did this
once in a prototype).
So we're renaming `Poll::Question::Answer` to `Poll::Question::Option`.
Hopefully that'll make it easier to remember. The name is also (more or
less) consistent with the `Legislation::QuestionOption` class, which is
similar.
We aren't changing the table or columns names for now in order to avoid
possible issues when upgrading (old code running with the new database
tables/columns after running the migrations but before deployment has
finished, for instance). We might do it in the future.
I've tried not to change the internationalization keys either so
existing translations would still be valid. However, since we have to
change the keys in `activerecord.yml` so methods like
`human_attribute_name` keep working, I'm also changing them in places
where similar keys were used (like `poll_question_answer` or
`poll/question/answer`).
Note that it isn't clear whether we should use `option` or
`question_option` in some cases. In order to keep things simple, we're
using `option` where we were using `answer` and `question_option` where
we were using `question_answer`.
Also note we're adding tests for the admin menu component, since at
first I forgot to change the `answers` reference there and all tests
passed.
Although most Consul Democracy installations will only have a few
available languages using `config.i18n.available_locales`, there's a
chance some installation will keep every language as available and will
enable the desired ones using the admin interface. In these cases,
enabling (or disabling) every language would be tedious, particularly
when casually experimenting in a staging environment or while using the
official Consul Democracy demo.
So we're adding buttons to simplify the process. Since some
installations might have only a couple of available languages, and in
this case these buttons would be pretty much useless, we're only showing
them when there are many languages available.
This way we can simplify the view, particularly the form. However, we're
still adding some complexity to the form so inputs are inside labels and
so the collection is easier to style with CSS.
We're using different controls depending on the number of available
locales.
When there are only a few locales, the solution is obvious: radio
buttons to select the default language, and checkboxes to select the
available ones are simple and intuitive.
With many languages, showing two consecutive lists of 30 languages could
be confusing, though, particularly on small devices, where scrolling
through both lists could be hard.
So, in this case, we're rendering a <select> to choose the default
language. For selecting the available languages, however, we're sticking
to checkboxes because all the other existing options (like multiple
selects) are hard to use. We think it's OK because the form doesn't have
any additional fields, and there's only one big list of options to
scroll through.
While testing the application, we noticed that if we use the
`admin-fieldset-separator` styles when there's only one fieldset, it's
harder to notice that there's an additional field to select the default
language. So we're only using the `admin-fieldset-separator` styles when
all the fields are grouped in fieldsets.
Regarding the help text for the fieldset, if we leave the help text
outside the <legend> tag, people using screen readers won't hear about
this content. However, if we include it inside the <legend> tag, some
screen readers might read it every time they move to a different
checkbox (or radio button), which can be annoying. Since I don't think
these help messages are really essential, I'm leaving them out of the
<legend> tag. It's also easier to style them if they're outside the
<legend> tag.
Note we're using `display: table` for the labels, for the reasons
mentioned in commit 923c2a7ee.
Also note that, when there's only one available locale, this section is
useless. In this case, we aren't disabling it for now because there's a
chance people see it in the official Consul Democracy demo and then
wonder why it isn't available on their installation. We might disable it
in the future, though.
Note that, for everything to work consistently, we need to make sure
that the default locale is one of the available locales.
Also note that we aren't overwriting the `#save ` method set by
globalize. I didn't feel too comfortable changing a monkey-patch which
ideally shouldn't be there in the first place, I haven't found a case
where `Globalize.locale` is `nil` (since it defaults to `I18n.locale`,
which should never be `nil`), so using `I18n.default_locale` probably
doesn't affect us.
Note that, currently, we take these settings from the database but we
don't provide a way to edit them through the admin interface, so the
locales must be manually introduced through a Rails console.
While we did consider using a comma-separated list, we're using spaces
in order to be consistent with the way we store the allowed content
types settings.
The `enabled_locales` nomenclature, which contrasts with
`available_locales`, is probably subconsciously based on similar
patterns like the one Nginx uses to enable sites.
Note that we aren't using `Setting.enabled_locales` in the globalize
initializer when setting the fallbacks. This means the following test
(which we could add to the shared globalizable examples) would fail:
```
it "Falls back to an enabled locale if the fallback is not enabled" do
Setting["locales.default"] = "en"
Setting["locales.enabled"] = "fr en"
allow(I18n.fallbacks).to receive(:[]).and_return([:fr, :es])
Globalize.set_fallbacks_to_all_available_locales
I18n.with_locale(:fr) do
expect(record.send(attribute)).to eq "In English"
end
end
```
The reason is that the code making this test pass could be:
```
def Globalize.set_fallbacks_to_all_available_locales
Globalize.fallbacks = I18n.available_locales.index_with do |locale|
((I18n.fallbacks[locale] & Setting.enabled_locales) + Setting.enabled_locales).uniq
end
end
```
However, this would make it impossible to run `rake db:migrate` on new
applications because the initializer would try to load the `Setting`
model but the `settings` table wouldn't exist at that point.
Besides, this is a really rare case that IMHO we don't need to support.
For this scenario, an installation would have to enable a locale, create
records with contents in that locale, then disable that locale and have
that locale as a fallback for a language where content for that record
wasn't created. If that happened, it would be solved by creating content
for that record in every enabled language.
Now that we've moved the logic to generate the events data to a model,
and we've got access to the model in the component rendering the chart,
we can render the data inside the chart instead of doing an extra AJAX
request to get the same data.
Originally, this was problaby done this way so the page wouldn't take
several seconds to load while preparing the data for the chart when
there are thousands of dates being displayed. With an AJAX call, the
page would load as fast as usual, and then the chart would render after
a few seconds. However, we can have an even better performance
improvement in this scenario if we use a Set instead of an Array. The
method `Array#include?`, which we were calling for every date in the
data, is much slower that `Set#merge`. So now both the page and the
chart load as fast as expected.
We could also use something like:
```
def add
(...)
shared_keys.push(*collection.keys)
end
def build
(...)
shared_keys.uniq.each do |k|
(...)
end
def shared_keys
@shared_keys ||= []
end
```
Or other approaches to avoid using `Array#include?`. The performance
would be similar to the one we get when using `Set`. We're using a `Set`
because it makes more obvious that `shared_keys` is supposed to contain
unique elements.
We've had some tests failing in the past due to these AJAX requests
being triggered automatically during the tests and no expectations
checking the requests have finished, so now we're reducing the amount of
flaky tests.
We were always displaying the event names in English.
Note we're changing the `user_supported_budgets` key because it didn't
make much sense; the investments are supported, and not the budgets.
We're also adding "created" to most of the event names in order to make
the texts more explicit, since not all the events refer to created data.
Note we're delegating the `t` method because i18n-tasks doesn't detect
code like `ApplicationController.helpers.t` and so reports we aren't
using the `admin.stats.graph` translations.
Using <h3> headings for the links had two disadvantages.
First, it was the wrong heading level to use, since there was no <h2>
tag before it.
Second, headings are supposed to be followed by content associated to
that heading; here, we had no content following the headings.
So we're using a list of links and giving it a heading. We're adding
styles so the page still looks like it used to, although these styles
are certainly asking for improvements.
The JavaScript required to display the chart wasn't loaded on the admin
stats page.
We're not adding a test because we're going to move the budgets graph to
a different page on the pull request containing this commit.
Note we're changing the "Go back" link, since using a turbolinks refresh
broke this link when using the Chromium browser. Besides, there was an
inconsistency where some of the "Go back" links in admin stats pointed
to the admin stats page but other links pointed to `:back`.
We were using Foundation's accordion menu to open/close nested lists of
links. Unfortunately, Foundation's accordion makes it impossible to
access links in nested links using the keyboard [1] (note the issue is
closed, but in the latest version of Foundation, 6.8.1, it's still
present, and Foundation's development is mostly discontinued).
Furtheremore, it adds the `menuitem` role to links, but ARIA menus are
not ment for navigation but for application behavior and, since it
doesn't add the `menubar` or `menu` roles to the parent elements, it
results in accessibility issues for people using screen readers (also
reported by the Axe accessibility testing engine).
So we need to implement our own solution. We're using the most commonly
used pattern: a buttton with the `aria-expanded` attribute. And, for
people using browsers where JavaScript hasn't loaded, we're keeping the
submenus open at all times (just like we were doing until now), and
we're disabling the buttons (since they do nothing without JavaScript).
This might not be an ideal solution, but it's probably good enough, and
way better than what we had until now.
We've also considered using the <details> and <summary> elements instead
of using buttons to open/close items on the list. However, these
elements still present some accessibility issues [2], and the transition
between open and closed can't be animated unless we overwrite the
`click` event with JavaScript. The pattern of using these elements to
open/close a nested list of links isn't common either, and some people
using screen readers might get confused when entering/leaving the nested
list.
We tried other approaches to get the animation effect, all of them based
on adding `[aria-expanded="false"]:not([disabled]) + * { display: none;
}` to the CSS file.
Unfortunately, animation using CSS isn't feasible right now because
browsers can't animate a change form `height: 0` to `height: auto`.
There are some hacks like animating the `max-height` or the `flex-grow`
property, but the resulting animation is inconsistent. A perfect
animation can be done using the `grid-template-rows` property [3], but
it requires adding a grid container and only works in Firefox and recent
versions of Chrome and similar browsers.
Getting to a solution with JavaScript was also tricky. With the
following approach, `slideToggle()` opened the menu the first time, even
if it was already open (not sure why):
```
toggle_buttons.on("click", function() {
$(this).attr("aria-expanded", !JSON.parse($(this).attr("aria-expanded")));
$(this).next().slideToggle();
});
```
This made the arrow turn after the menu had slided instead of doing it
at the same time:
```
toggle_buttons.on("click", function() {
var button = $(this);
button.next().slideToggle(function() {
button.attr("aria-expanded",
!JSON.parse(button.attr("aria-expanded")));
});
}
```
With this, everything disappeared quickly:
```
toggle_buttons.on("click", function() {
var expanded = JSON.parse($(this).attr("aria-expanded"));
if (expanded) {
$(this).next().slideUp();
} else {
$(this).next().slideDown();
}
$(this).attr("aria-expanded", !expanded);
}
```
So, in the end, we're hiding the nested link lists with JavaScript
instead of CSS.

Before this change, two important things depend on the format of each key,
where to render it in the administration panel and which kind of interface
to use for each setting. Following this strategy led us to a very complex
code, very difficult to maintain or modify. So, we do not want to depend
on the setting key structure anymore to decide how or where to render each
setting.
With this commit, we get rid of the key format-based rules. Now we render
each setting explicitly passing to it the type and the tab where it belongs.
We applied the Capybara/SpecificMatcher in commit f52a86b46. However,
this rule doesn't convert methods finding <a> tags to methods finding
links because <a> tags only count as links when they've got the `href`
attribute. For instance, in the `xss_spec.rb` file we check what happens
when clicking on an anchor tag because we're testing that the `href`
attribute has been removed and so we can't use `click_link`.
So, basically, we can't enable a rule to automatically detect when we're
using `have_css` instead of `have_link`, but we should still do it
because `have_link` adds an extra check which affects accessibility
since it makes sure the tag has the `href` attribute and so it's
recognizable as a link by screen readers.
This rule was added in rubocop-rspec 2.12.0, and we were already
following it most of the time.
However, the rule isn't working correctly in some cases, such as input
selectors, so we aren't enabling it.
Note we're excluding a few files:
* Configuration files that weren't generated by us
* Migration files that weren't generated by us
* The Gemfile, since it includes an important comment that must be on
the same line as the gem declaration
* The Budget::Stats class, since the heading statistics are a mess and
having shorter lines would require a lot of refactoring
Note that in the budgets wizard test we now create district with no
associated geozone, so the text "all city" will appear in the districts
table too, meaning we can't use `within "section", text: "All city" do`
anymore since it would result in an ambiguous match.

This is consistent with the component for balloting stats. We're about
to change both components, and the changes are easier to follow if
they're similar.
We're also using consistent names in methods.
To get the heading where a user voted, we were relying on the
`balloted_heading_id` field.
Our guess is this was done so the total number of users is the same as
the sum of users who voted on a heading. That is, if 2000 people voted
just on the "All city" heading, 1000 voted just on the "North district"
heading, and 500 people voted on both, instead of showing "3500 people
voted in total, 2500 voted in all city, 1500 voted in north district",
we show something like "3500 people voted in total, 2250 voted in all
city, and 1250 voted in north district".
However, this approach has some disadvantages.
The first disadvantage is, the stats aren't correct. In the case above,
2500 voted on the "All city heading", so the statistics for this heading
don't show reality.
The second one is we weren't considering the last heading where users
voted inside the budget being displayed, but the last heading where
users voted, period. That means that, if all the people above voted on a
later budget, the stats for the budget above would become "3500 people
voted in total, 0 voted in all city, and 0 voted in north district".
That also means we were including headings from previous budgets in the
statistics for more recent budgets when people hadn't voted on the
recent ones.
So we're removing the `balloted_heading_id` since its data is lost once
people vote on a new budget. And, in order to show the right stats and
simplify the code, we're no longer trying to add votes just to one
heading when users vote on several headings.

We're also moving the tests, but we're keeping one system test in order
to test the controller and the navigation to get to this page.
Note we're slightly changing the order of the methods in the component;
the order of the instance variables was `user_`, `vote_`, `vote_`,
`user_`, which was hard to follow.
We weren't showing the year when a page was created/updated, and we
were displaying the created date instead of the updated one.

We were using the same logic in four different places, so we're creating
a new class to handle that logic.
Note that I didn't find a way to delegate the `content` method to a
`Admin::TableActionsComponent`, so we're delegating the `action` method
instead. That means we need to create a method returning an
`Admin::TableActionsComponent`. We also need to cache this object;
otherwise we were getting an error when calling `actions.action` from
the `Admin::Poll::Questions::TableActionsComponent`.
