Clear instance variable names help understand what's going around when
you're deep 2 or 3 partials. In this case @budget is only used to carry
around the current_budget so @current_budget is more descriptive.
Using `current_budget` directly around would be an alternative, but
maybe not as maintainable in case we want to change which budget is
being shown (for example the drafting one if you're admin).
We only need finished budget's at budget's index "Finished budgets"
section. So we add the `finished` scope to @budgets variable, and rename
it so its clear what it contains.
Also avoid showing the "Finished budgets" section if there is none
Why:
We need to clear associated rails cache keys in order for changes to be
ready to be seen on the views
How:
* Just an after_save callback to a private method
Why:
Somehow we're seeing communities without proposals at production. We
must find why and fix it, but first we need to throw a 404 at the user
instead of a 500 internal server error
How:
First catching the scenario of non-existent communitable at the
controller and raising a 404 error. Secondly preventing the author_id
access over a possibly nil object, this is a smell but it can't be
easily fixed right now... we need to correctly implement a relation
between Community and communitable and avoid the multiple occurences of
`community.from_proposal?` in the codebase that makes it impossible to
extend to a fourth communitable model.
Why:
The html tags weren't removed from the text that was rendered at the
social metatags (twitter & facebook), neither scaped so adding a quoted
text would endup breaking the metatag content and writting in plain
sight the description at the browser view.
How:
Saniziting the text and truncating it afterwards since we don't need to
send more than 140 chars for twitter/facebook social cards.
Why:
The Admin Budget form has a submit button for saving the record, adding
another submit input to destroy the record actually adds to the html:
`<input type="hidden" name="_method" value="delete">` and it collides
with the save button, forcing it to perform a destroy instead of save.
Previously the destroy button was not in the same div as the save button
How:
Just changing the Destroy from a button_to to a link_to.
