Having exceptions is better than having silent bugs.
There are a few methods I've kept the same way they were.
The `RelatedContentScore#score_with_opposite` method is a bit peculiar:
it creates scores for both itself and the opposite related content,
which means the opposite related content will try to create the same
scores as well.
We've already got a test to check `Budget::Ballot#add_investment` when
creating a line fails ("Edge case voting a non-elegible investment").
Finally, the method `User#send_oauth_confirmation_instructions` doesn't
update the record when the email address isn't already present, leading
to the test "Try to register with the email of an already existing user,
when an unconfirmed email was provided by oauth" fo fail if we raise an
exception for an invalid user. That's because updating a user's email
doesn't update the database automatically, but instead a confirmation
email is sent.
There are also a few false positives for classes which don't have bang
methods (like the GraphQL classes) or destroying attachments.
For these reasons, I'm adding the rule with a "Refactor" severity,
meaning it's a rule we can break if necessary.
While in theory we wouldn't need to use the `transient` nor the
`after(:create)` because there's already a `has_many :through`
association with followers, Factory Bot / ActiveRecord don't
automatically associate the followable, resulting in an invalid record
exception.
We're using `eq` and `match_array` in most places, but there were a few
places where we were still checking each element is included in the
array. This is a bit dangerous, because the array could have duplicate
elements, and we wouldn't detect them with `include`.
We were using `to_sentence` to check the order, while it's easier to
just check the exact contents of the array.
Furthermore, using `to_sentence` checked the order of the array, so it
was a potentially flaky spec since the method doesn't specify an order
and PostgreSQL doesn't guarantee the order of the records.
Joining the translations table caused duplicate records to appear.
Ordering with SQL is simply too hard because we need to consider
fallback locales.
Thanks Senén for providing most of the tests in the poll spec.
I've moved the method to the User model in order to make it easier to
test. I'm not sure where it belongs, though.
There was already a failing spec in `spec/features/management_spec.rb`,
but it passed if run standalone because it only failed if previous tests
had already created nine users or more.
We were seeing an exceptions in the home page when displaying
recommendations. This was due to trying to load tags of hidden proposals
With this commit we are skipping proposals that that have been hidden,
which will hopefully solve this exception
allows managers to create users without email
hides email preferences from account page for email-less users
prevents email delivery to users with no email
adds spec for user creation from management
adds specs for user's email requirement
adds spec for no deliveries if no email
