When there was a custom JavaScript file, we weren't loading the original
one, meaning that, in order to customize it, it was necessary to copy
the whole original file and then changing it.
Now we're loading both the original and the custom file, so the custom
file can simply add more functions or overwrite the ones we'd like to
customize, without copying the whole file.
Existing copies of original files will still overwrite the whole file
and won't be affected.
Defining a behavior on hover means making it different for people using
a keyboard or a touchscreen (most of the population, nowadays).
In this case, we had an accessibility issue where the message wouldn't
disappear once it appeared. That meant that, after tabbing through all
the links and buttons in, for instance, the debates index, the page
would be filled with "participation not allowed" messages, and in order
to see the information about how many people have voted, reloading the
page was required.
For touchscreen users the behavior was similar to what we get on hover,
although we've found some inconsistencies when trying to support several
elements on the same page.
We think in proposals it makes sense to hide the "support" button when
users click on it, and the same applies to the buttonsto support and
vote investment projects. However, we aren't hiding the buttons to
agree/disagree with a debate in order to keep the information about the
current number of people agreeing and disagreeing visible.
Note we're removing some support spec methods because after these
changes the duplication isn't as obvious as it was in the past.
This message is only shown in the `show` action, so it's shown at most
once in the whole page, so it doesn't take up too much space and it
isn't as overwhelming as if we were showing it on the index page, once
per debate.
We're only showing it when there are closed options, though, since
there's already a message to sign in to comment when the question
accepts open answers.
Very similar code is present in the `votes.js` file. Since the only
elements with the `js-participation-not-allowed` class also matched the
`div.supports div.participation-not-allowed` selector, for these
elements the events were executed twice.
So we can get rid of the `js-participation` class alongside all the
JavaScript code referencing it.
As mentioned in commit bc0f04075, a <select> field which submits its
form on change causes many accessibility and usability issues. In this
case there was also an incompatibility with the advanced search filter
which caused a bug solved in commit 541a5fa89.
So the question is where to position the filters and how to display
them. One factor to take into the account is how relevant these filters
are, particularly compared to the links to select the prefered order,
since we don't usually give users the choice of both filters and orders.
Our filters don't really make sense until the valuation phase starts,
since before that phase investments aren't selected nor their
feasibility is decided.
After that phase, the only phase where citizens are really involved
is the final voting; the rest of the phases are done by valuators and
administrators. In the final voting, citizens can only vote on selected
projects, and that's the default filter during that phase.
So these filters are mainly there for information purposes, and not to
help citizens in the phases where they're actually involved (accepting
projects, selecting projects and balloting).
Orders, on the other hand, play a crucial role during the final voting
phase. Since citizens might have already voted for a few projects and
have, let's say, 100,000€ left, ordering by price allows them to find
which projects are within their remaining budget.
In conclusion, orders are more important than filters, and so they
should have a more prominent place.
For consistency with the proposals section, where we've got some links
in the sidebar (bottom part of the page on small screens) providing a
similar funcionality, like accessing selected proposals or archived or
retired proposals, we're moving the investments filters to the sidebar
(bottom part of the page on small screens) as well.
Its value is difficult to read due to the low contrast between the color
of the field and the color of the placeholder text, and we already have
the same information in the hint above it.
Sometimes tests were hanging indefinitely. Debugging shows that in some
cases it's due to submitting a form before the AJAX request to get
proposals, debates or investments suggestions is finished, since having
an AJAX and a non-AJAX request at the same time when running the test
sometimes leads to unexpected results.
In our case, we were having many timeouts in Github Actions in the
branches where we use both ActiveStorage and Paperclip to store files
(based on pull request 4598). I can reproduce it in those branches
running the following test ("Should show new image after successful
creation with one uploaded file"), although only when my laptop isn't
plugged (!!):
```
rspec './spec/system/proposals_spec.rb[1:33:1:14]'
```
Since we didn't have a proper way to know the AJAX request had finished,
we're adding a `suggest-success` class to the element showing the
suggestions when that happens. Then in the tests we can look for that
class after filling in the title of a proposal, debate or investments.
Just for clarity's sake, we're also adding the `suggest-loading` class
when the suggestions are loading.
In order not to have expectations everywhere about the suggestions,
we're extracting methods to fill in those titles in the tests. Note we
aren't using these methods in the "edit" actions (suggestions are not
showing when editing) or in tests with the `no_js` tag (since
suggestions only work with JavaScript).
Our previous system to delete cached attachments didn't work for
documents because the `custom_hash_data` is different for files created
from a file and files created from cached attachments.
When creating a document attachment, the name of the file is taken into
account to calculate the hash. Let's say the original file name is
"logo.pdf", and the generated hash is "123456". The cached attachment
will be "123456.pdf", so the generated hash using the cached attachment
will be something different, like "28af3". So the file that will be
removed will be "28af3.pdf", and not "123456.pdf", which will still be
present.
Furthermore, there are times where users choose a file and then they
close the browser or go to a different page. In those cases, we weren't
deleting the cached attachments either.
So we're adding a rake task to delete these files once a day. This way
we can simplify the logic we were using to destroy cached attachments.
Note there's related a bug in documents: when editing a record (for
example, a proposal), if the title of the document changes, its hash
changes, and so it will be impossible to generate a link to that
document. Changing the way this hash is generated is not an option
because it would break links to existing files. We'll try to fix it when
moving to Active Storage.
We introduced a bug in commit acbd1b023.
When editing a record and removing an existing image, we don't remove
the HTML fields associated with that image but simply hide them, and
then we add fields to create a new image when clicking on "Add image".
This is standard cocoon behavior. However, since in the case of images
there's a `has_one` relation, cocoon doesn't add unique identifiers to
the new fields, generating duplicate IDs, which is invalid HTML.
Since there's a duplicate file input ID, clicking on the "Choose image"
label we aren't clicking on the new input but on the old one. This means
we aren't correctly attaching an image. The tests passed because
Capybara uses the equivalent of a keyboard to select the field, and in
this case everything worked properly.
So we need to delete the existing elements before inserting new ones.
We're adding a test to check there aren't duplicate IDs.
We were hiding the file input and styling the label as a button instead.
Since clicking on a label has the same effect as clicking on the input,
the input worked properly for mouse and touch screen users.
However, hiding the input makes it inaccessible for keyboard users,
since labels don't get keyboard focus, but inputs do.
So we must not hide the input but make it invisible instead. But we
still need to hide the input (alongside the label) after a file has been
attached.
We could add some extra JavaScript to hide the input when we hide the
label. Since the JavaScript is already quite complex and my first few
attempts at changing it failed, I've opted to assume that the input (and
its label) must be hidden whenever there's already a file name, and
implement that rule with CSS.
Note we're using the `:focus-within` pseudoclass to style a label when
focus is on the input. This rule (at the time of writing) is only
supported by 93.5% of the browsers. Keyboard users without a screen
reader and using the other 6.5% of the browsers will still be able to
focus on the field but might not notice the field has received focus.
Since the percentage of affected users will decrease over time and until
now 100% of keyboard users were completely unable to focus on these
fields, for now we think this is a good-enough solution.
We were already defining the links with data-remote and data-method, so
instead of manually doing an AJAX request we can rely on Rails to
perform the request and then handle the `ajax:complete` event.
This way screen reader users will hear the name of the file before
hearing about the link to destroy it. We were already displaying it this
way visually by having the file name on the left and the destroy link on
the right.
Thanks to this change we can also simplify the code which dynamically
changed the layout.
Since elements are created and destroyed, we don't have to do any kind
of "reset" before destroying or creating them. We would have to do so if
we were just hiding the elements in order to show them again later, but
that's not the case.
The language attribute is present in all layouts since commit 025923ac4,
so there's no need to use the language selector locale. Besides, it
wouldn't work if there's only one locale and the language selector isn't
shown.
Since forms are landmarks, screen reader users might navigate to the
form. But then they were going to find an empty form with no way to
toggle it.
Moving the button inside the form means screen reader users navigating
to the form will find the button to toggle it.
It also helps us simplifying the code; there's no need to use
data-attributes to communicate whether the form should be visible since
now we can easily use the button `aria-expanded` attribute.
We could further simplify the JavaScript if we used a CSS rule to
show/hide the form fields based on the toggle button `aria-expanded`
attribute. However, implementing the "slide" animation we use when
toggling the form with CSS is difficult and unreliable.
We were using the form and then showing it with JavaScript when advanced
search terms were present. Now we hide it with JavaScript when no
advanced search are present. This means users without JavaScript
(including users with JavaScript enabled but bad internet connections
preventing the JavaScript to load) can now access the form.
The other main difference between the two versions is the way the form
flashes while JavaScript is loading.
Previously, the form would always be hidden when no terms had been
introduced. However, when these terms were present, after submitting the
form it would briefly be hidden and then shown again.
Now the opposite happens. When advanced search terms are present, the
form is shown at all times. However, when they aren't, the form is
briefly shown before it disappears.
Here the previous behavior is arguably better because most of the time
these terms will not be present.
So basically we're significantly improving the experience of some users
at the cost of slightly worsen the experience of other users.
We're also hiding the button to show the form when JavaScript is
disabled, since in this scenario it's useless. We're using the `hidden`
attribute so hidden buttons can be detected in CSS.
Users (particularly, screen reader users) usually identify links with
things that take you somewhere, and buttons with things that either send
forms or change things on the page.
Using a button we can also use the `aria-expanded` attribute, meaning
screen reader users will know that the button has two states ("expanded"
and "collapsed"), the current state of the button, and will get
immediate feedback when clicking the button because the new state of the
button will be announced.
Thanks to this change, we can also slightly simplify the code; we
obviously have to remove the (useless) `href` attribute, and we don't
have to prevent the default event in JavaScript since there's no default
event for buttons with `type="button"`.
Note we're keeping this section's original design (which had one button
to add a new group which after being pressed was replaced by a button to
cancel) but we aren't using Foundation's `data-toggle` because there
were a couple of usability and accessibility issues.
First, using `data-toggle` multiple times and applying it to multiple
elements led to the "cancel" button not being available after submitting
a form with errors. Fixing it made the code more complicated.
Second, the "Add new group" button always had the `aria-expanded`
attribute set to "true", so my screen reader was announcing the button
as expanded even when it wasn't. I didn't manage to fix it using
`data-toggle`.
Finally, after pressing either the "Add new group" and "Cancel" buttons,
the keyboard focus was lost since the elements disappeared.
So we're simplifying the HTML and adding some custom JavaScript to be
able to handle the focus and manually setting the `aria-expanded`
attribute.

Now it's easier to change the investments filter. Previously we had to
go back to the budget index page, change the filter there, and then
select one heading.
Now the links to change the current filter in the budget index page
aren't needed anymore.
We were using list items with the checkbox role. This is probably
confusing since list items have a listitem role, and so we were
basically using a list with no listitem.
We could add a `<span role="checkbox">` tag inside the list item, but
using real checkboxes is probably easier. We're also adding a test to
verify the checkboxes native behavior is compatible with our code.
Note we're using the "enter" key to toggle the "checked" status of the
SDG. This is probably not intuitive for screen reader users who might
try to submit the form using the "enter" key after selecting a goal.
However, the alternative would be even less intuitive for sighted
keyboard users, since for them these icons look like links or buttons
and they would accidentally submit the form when trying to select a
goal.
Since we haven't come up with a better interface yet, for now we're
following the principle of least damage; we consider submitting the form
against a user's will is less annoying than forcing users to move to a
different field before being able to submit the form.
Also note we can't write `check` in the tests because Capybara will try
to click the checkbox, which is hidden by the image in the label.
Using a button tag, it's possible for every user to "click" the element.
Besides, we don't need to call the `preventDefault` function, because
buttons with type "button" don't do anything by default.
We were using a custom icon because in the past social-share-button
didn't have support for whatsapp. But now that it does, we can remove
our custom icon.
Note we're using the `_app` suffix because that's the name of the icon
meant for mobile devices.
Note we're using both the `hidden` and `disabled` properties to
guarantee compatibility with user agents which might still display the
option even when using the `hidden` attribute or hiding it with
`display: none`. We could also use `hide()` and `show()` instead of the
`hidden` property, but since we're using the `disabled` property, I
thought the code would be easier to read if we used properties in both
cases.
Also note users will no longer be able to get, let's say, debates which
are related to goal 1 and target 2.1. We think this use case is highly
unlikely and there's no need to take it into account.
Add "display_text" to allow customize the text that we want render on tag.
For Goals we render "SDG1", "SDG2"..
For Targets we render the code "1.1", "1.A"...
- When we click on an icon we add a new tag with the Goal related to the input or
we remove the tag when that label already exists.
- Manage goals icons status when add or remove related targets:
Whenever there is a tag related to Goal, either the Goal itself or a Target, the icon
will be "checked".
When there is no related Goal or Target it will no longer be marked as checked.
This will allow autocomplete for the loaded values in suggestions settings.
We remove commas on tag to allow to jquery.amsify.suggestag.js use comma
as delimiter.
This component allows you to add Goals and Targets in a single
input to relate it to any resource.
We use the new added library to render them as tags.
Now that comments and TOC can be closed at the same time, we use a flex
layout so the main content uses the available width.
We're also making the comments work better on medium-sized screens,
since previously they had a fixed width and now the width is adapted to
the size of the screen.
Since now the comment box element has a relative position instead of an
absolute one, we need to consider the draft panel height when
calculating the comment box position.
We were using JavaScript to show/hide the Table of Contents.
In my humble opinion, the <details> tag has a few shortcomings [1][2],
which means we should be careful about when to use it.
IMHO a Table of Contents is a good candidate for this tag because it's a
very common pattern to add a show/hide behavior for it, even if using it
means the "navigation" role (which we are *not* using anyway) wouldn't
be identified correctly.
I'm adding a <details> tag to the comments section as well for
consistency and in order to simplify the code. I'm not sure this is as
good an application of the <details> tag, though, but then again I'm not
sure about the interface we use to show/hide the comments (and this
feeling is increased by the fact that we use a different interface on
small screens). If we decide to change the interface in the future, we
might consider using the <details> tag for the Table of Contents but not
for the comments.
Since the <details> tag is not supported on Internet Explorer, I'm
only adding styles to this tag using the `:not([open])` option. On
Internet Explorer <details> will always be opened and so these styles
will be ignored.
