So now we test in depth at the model level, and can be a bit more
relaxed about integration tests for translations.
Note we're defining some extra factories to make sure all translatable
attributes with presence validation rules are mandatory. This way we can
simplify the way we obtain required fields, using `required_attribute?`.
Otherwise, fields having an `unless` condition in their presence
validation rules would count as mandatory even when they're not.
We don't need `before` blocks because we've removed the `after` blocks,
and we don't need to define available locales because we already do so
in the test environment file.
We already configure `I18n.locale` and we reset Globalize's fallbacks
before every test.
On the other hand, RSpec automatically resets anything which is stub
with `allow`, so there's no need to use `and_call_original` in an
`after` block.
When we were visiting a page showing the content of a record which uses
globalize and our locale was the default one and there was no
translation for the default locale, the application was crashing in some
places because there are no fallbacks for the default locale.
For example, when visiting a legislation process, the line with
`CGI.escape(title)` was crashing because `title` was `nil` for the
default locale.
We've decided to solve this issue by using any available translations as
globalize fallbacks instead of showing a 404 error or a translation
missing error because these solutions would (we thinkg) either require
modifying many places in the application or making the translatable
logic even more complex.
Initially we tried to add this solution to an initializer, but it must
be called after initializing the application so I18n.fallbacks[locale]
gets the value defined in config.i18n.fallbacks.
Also note the line:
fallbacks[locale] = I18n.fallbacks[locale] + I18n.available_locales
Doesn't mention `I18n.default_locale` because the method
`I18n.fallbacks[locale]` automatically adds the default locale.
