These cases aren't covered by the `Rails/WhereRange` rubocop rule, but
IMHO using ranges makes them more consistent. Besides, they generate SQL
which is more consistent with what Rails usually generates. For example,
`Poll.where("starts_at <= :time and ends_at >= :time", time:
Time.current)` generates:
```
SELECT \"polls\".\"id\", (...) WHERE \"polls\".\"hidden_at\" IS NULL AND
(starts_at <= '2024-07-(...)' and ends_at >= '2024-07-(...)')
```
And `Poll.where(starts_at: ..Time.current, ends_at: Time.current..)`
generates:
```
SELECT \"polls\".\"id\", (...) WHERE \"polls\".\"hidden_at\" IS NULL AND
\"polls\".\"starts_at\" <= '2024-07-(...)' AND \"polls\".\"ends_at\" >=
'2024-07-(...)'"
```
Note that the `not_archived` scope in proposals slightly changes, since
we were using `>` and now we use the equivalent of `>=`. However, since
the `created_at` field is a time, this will only mean that a proposal
will be archived about one microsecond later.
For consistency, we're also changing the `archived` scope, so a proposal
is never archived and not archived at the same time (not even for a
microsecond).
Not doing so has a few gotchas when working with relations, particularly
with records which are not stored in the database.
I'm excluding the related content file because it's got a very peculiar
relationship with itself: the `has_one :opposite_related_content` has no
inverse; the relation itself is its inverse. It's a false positive since
the inverse condition is true:
```
content.opposite_related_content.opposite_related_content.object_id ==
content.object_id
```
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.
