This code was introduced in commit 722a431b, but it stopped being used
in commit 7657a0e0.
The spec was failing sometimes because the method didn't order the
records, but the spec checked the records returned in a certain order.
Furthermore, the method `page` generated a potential conflict with
kaminari's `page method.
We have two models called `Answer`: The `Answer` model and the `Poll::Answer` model.
This conflict ocurrs when trying to create a user generated poll for a proposal. from the Dashboard. In that case we are getting an exception, only in the development environment, as the class `Answer` is loaded before the class `Poll::Answer` which is the one we want to use.
With this commit we are explicitly requiring the correct model, solving the class conflict.
For some reason the paperclip method `attachment.exists?' was
returning nil even when `attachment.url(style)' was correctly
returning the url/path of the attachment.
Therefore returning `nil' was causing to raise an error in the
method `image_tag'.
With this change we make sure we return the image url it it's
available, or an empty string if it's not, but never a null value.
Metrics/LineLength: Line is too long.
RSpec/InstanceVariable: Use let instead of an instance variable.
Layout/TrailingBlankLines: Final newline missing.
Style/StringLiterals: Prefer double-quoted strings.
Maintain the method for models that are still translatable. This help
me to pass the CI build. In later PR's this method will be eliminated
as no one will invoke it.
Move method from sanitizable to globalizable concern because
globalize_accessors were overiding sanitizable method and was never
called. Another solution to this could be to load sanitizable
always after globalizable concern.
Old method implementation was not working well with globalize_accessors,
it was returning nil always.
Some queries were accessing original column instead of the new translatable one. This should have been causing unexpected behavior for requests maded in a different locale than the application default.
