Having a class named `Poll::Question::Answer` and another class named
`Poll::Answer` was so confusing that no developer working on the project
has ever been capable of remembering which is which for more than a few
seconds.
Furthermore, we're planning to add open answers to polls, and we might
add a reference from the `poll_answers` table to the
`poll_question_answers` table to property differentiate between open
answers and closed answers. Having yet another thing named answer would
be more than what our brains can handle (we know it because we did this
once in a prototype).
So we're renaming `Poll::Question::Answer` to `Poll::Question::Option`.
Hopefully that'll make it easier to remember. The name is also (more or
less) consistent with the `Legislation::QuestionOption` class, which is
similar.
We aren't changing the table or columns names for now in order to avoid
possible issues when upgrading (old code running with the new database
tables/columns after running the migrations but before deployment has
finished, for instance). We might do it in the future.
I've tried not to change the internationalization keys either so
existing translations would still be valid. However, since we have to
change the keys in `activerecord.yml` so methods like
`human_attribute_name` keep working, I'm also changing them in places
where similar keys were used (like `poll_question_answer` or
`poll/question/answer`).
Note that it isn't clear whether we should use `option` or
`question_option` in some cases. In order to keep things simple, we're
using `option` where we were using `answer` and `question_option` where
we were using `question_answer`.
Also note we're adding tests for the admin menu component, since at
first I forgot to change the `answers` reference there and all tests
passed.
In case we receive consecutive requests we are locking the poll author record
until the first request transaction ends, so the author answers count during
subsequent requests validations is up to date.
Up until now, we were assuming the voter was valid, but were not raising
an exception if it wasn't. And in the user interface everything seemed
to be working properly.
We were having this issue when skipping verification, when there could
be voters without a document number, which would be considered invalid.
Raising an exception when failing to save the voter and making sure the
answer and the voter are saved inside a transaction solves the problem.
We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.

We barely use this trait. In the votation type spec we're probably using
it wrong, and in the answer spec we assume one of the answers is going
to be "Yes".
The name `yes_no` is more expressive, since it makes it clear what the
answers are.
