The initialjs-rails gem hasn't been maintained for years, and it
currently requires `railties < 7.0`, meaning we can't upgrade to Rails 7
while we depend on it.
Since the code in the gem is simple, and we were already rewriting its
most complex part (generating a background color), we can implement the
same code, only we're using Ruby instead of JavaScript. This way, the
avatars will be shown on browsers without JavaScript as well. Since
we're adding a component test that checks SVG images are displayed even
without JavaScript, we no longer need the test that checked images were
displayed after AJAX requests.
Now the tests show the user experience better; people don't care about
the internal name used to select the initial (which is what we were
checking); they care about the initial actually displayed.
Note initialjs generated an <img> tag using a `src="data:image/svg+xml;`
attribute. We're generating an <svg> tag instead, because it's easier.
For this reason, we need to change the code slightly, giving the <svg>
tag the `img` role and using `aria-label` so its contents won't be read
aloud by screen readers. We could give it a `presentation` role instead
and forget about `aria-label`, but then screen readers would read the
text anyway (or, at least, some of them would).
This rule was added in rubocop-capybara 2.19.0. We were following it
about 85% of the time.
Now we won't have to check both have_css and have_selector when
searching the code.
After a user assigned as a budget admin deletes their account or gets blocked by
a moderator, the application throws an exception while loading the admin
investment index page.
As an erased user is not really deleted and neither its associated roles, the
application was failing when trying to sort and administration without a
username. In this case, the application was throwing an `ArgumentError:
comparison of NilClass with String failed` exception.
As a blocked user is not deleted or its roles, the application failed when trying
to access the user name through the delegation in the Administrator. In this
case, the application was throwing a `NoMethodError: undefined method `name' for
nil:NilClass` exception.
We check the changes have been saved and we check recommendations have
been disabled after visiting the debates and proposals pages. The
latter helps us avoid accessing the database after the process running
the browser has been started.
