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 reduce code duplication thanks to that, and make it easier
to change this field.
Note that there was one place where the "16.years" value was
hardcoded. We're moving the test for this case to the
component and changing it so the test doesn't use the default
age.
We're also removing the redundant helper method that had the
same code as a method in the User class which is called
everywhere else.
We were using similar code in four different places; six, if we count
the welcome pages seeds. Reducing duplication in the pages seeds is a
bit tricky because administrators are supposed to edit their content and
might remove the HTML class we use to define styles. However, we can
share the code everywhere else.
Note that there's a bug in the application since we show that level 2
users cannot vote for budget projects but we give them permission to do
so in the abilities model. We're keeping the same behavior after this
refactoring but we might change it in the future.
We had a link to `/census_terms`, and by looking at the code, it wasn't
so clear where this URL came from.
Using `page_path`, it's easier to understand that it comes from a page
with the `census_term` slug. It also means we'll find this line when
searching for usages of `page_path` in the code.
We forgot to remove it in commit f28a5cc49.
The generated HTML was invalid, with the error:
> Element meta is missing one or more of the following attributes:
> content, property.
Using `<a>` tags with no `href` means these elements cannot be activated
by keyboard users, so we're replacing them with buttons.
In the future we probably want to add more consistency so all toggle
buttons use the same code. We might also add styles depending on the
`aria-expanded` property.
Using the `_html` suffix in an i18n key is the same as using `html_safe`
on it, which means that translation could potentially be used for XSS
attacks.
Using the block syntax to generate the label with a <span> tag inside
isn't necessary after upgrading foundation_rails_helpers. Before the
upgrade, we couldn't do so because the <span> tag was escaped.
Not doing so caused crashes on applications which don't fall back to
English when a translation is missing.
We're adding them in a separate file so we can exclude it from crowdin
and so translators don't translate symbols as if they were words which
need translation.
