HasManyDependent Usage

[kevin-j-m]

Rubocop 0.50.0 includes a new rails cop (PR) for recommending an enforced dependent attribute on has_many or has_one associations.

It seems reasonable to me to include these, but at least for me, is not how I've written associations thus far, unless necessary. Granted, now that we have foreign_key constraints, if you're using them and don't provide a dependent action, then your deletion is going to fail, due to a foreign key constraint error.

Anyhow, I wanted to raise awareness on this if nothing else, but also give people the chance to chime in on the default configuration (to warn about the lack of a dependent attribute), but also if people have guidelines/suggestions on which dependent option to use in certain scenarios, if we want to get that far in the weeds (rubocop won't advise on what option to use, just to have one).

There is currently a bug in 0.50.0 where this will report on has_x through: associations, where it shouldn't.

It looks like this has been fixed in master, but not yet released. So, if you see this for a through, I'd just ignore for now.
