In commit 905ac48bb we activated exceptions when assets were not found,
in order to detect places where we were trying to load non-existent
images.
We got an exception for that reason: we were loading images based on the
current locale, but for some locales there was no images.
We're now using fallbacks and loading another image when the original
one isn't available.
Note we're copying the English images to images with a generic name for
the case where there's no fallback with an image. We're copying the
files instead of using symbolic links to make sure they can be
overwritten independently in other CONSUL installations.
Also note we're updating the HTML so the section gets the ID instead of
the header. That way the system test is simple.
Now the banner component accepts either a banner or a section and loads
the banner if it's a section, so we don't have to add the `@banners`
variable in several controllers.
A list of links is a very common pattern in the web, and we use it in
many places. Here we're applying it to one of the most simple ones; the
help page.
Generally speaking, I'm not a big fan of helpers, but there are methods
which IMHO qualify as helpers when:
* They do not deal with application objects but mainly strings and
arrays
* They return text or an HTML tag
* Their logic is simple and splitting it into several methods is not
necessary
Many Rails helpers, like `tag`, follow these principles.
Using the `_html` suffix automatically marks texts as HTML safe, so
doing so on sanitized texts is redundant.
Note flash texts are not sanitized the moment they are generated, but
are sanitized when displayed in the view.
Sometimes we're interpolating a link inside a translation, and marking
the whole translations as HTML safe.
However, some translations added by admins to the database or through
crowdin are not entirely under our control.
Although AFAIK crowdin checks for potential cross-site scripting
attacks, it's a good practice to sanitize parts of a string potentially
out of our control before marking the string as HTML safe.
From now on these static pages:
`/privacy'
`/conditions'
`/accesibility'
`/help/faq'
`/welcome'
have been moved to the DB and can be modified easily by any
administrator in `/admin/site_customization/pages'
Banners were not been shown in certain pages; now
they are.
Spec to check if the banner is been shown correctly
added. Before it was in admins specs, now it has it's
own spec out of admins folder.
