This way we guarantee there will be at least one translation for a model
and we keep compatibility with the rest of the application, which
ideally isn't aware of globalize.
This change forces us to use nested attributes for translations, instead
of using the more convenient `:"title_#{locale}"` methods.
On the other hand, we can use Rails' native `_destroy` attribute to
remove existing translations, so we don't have to use our custom
`delete_translations`, which was a bit buggy since it didn't consider
failed updates.
It turns out it is not necessary to downcase and underscore
locale names to use the globalize-accessor gem. The gem
will automatically underscore the locale name when defining and
calling the accessor methods.
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.
Banner sections can be saved (one banner can appear in several sections)
If the hex color is changed in the textfield, the color of the color picker changes.
