Use frozen-string-literal in ActiveRecord
2017-07-09 13:41:28 -04:00
# frozen_string_literal: true
Providing support for :inverse_of as an option to associations. You can now add an :inverse_of option to has_one, has_many and belongs_to associations. This is best described with an example: class Man < ActiveRecord::Base has_one :face, :inverse_of => :man end class Face < ActiveRecord::Base belongs_to :man, :inverse_of => :face end m = Man.first f = m.face Without :inverse_of m and f.man would be different instances of the same object (f.man being pulled from the database again). With these new :inverse_of options m and f.man are the same in memory instance. Currently :inverse_of supports has_one and has_many (but not the :through variants) associations. It also supplies inverse support for belongs_to associations where the inverse is a has_one and it's not a polymorphic.

class Interest < ActiveRecord::Base
Replace test `Man` with `Human` The commit replaces the `Man` model used in tests with a `Human` model. It also replaces the existing `Human` model with a `SuperHuman` model inheriting from `Human`. While this may seem like a cosmetic change, I see it as more of an inclusivity change. I think it makes sense for a number of reasons: * Prior to this commit the `Human` model inherited from `Man`. At best this makes no sense (it should be the other way around). At worst it is offensive and harmful to the community. * It doesn't seem inclusive to me to have exclusively male-gendered examples in the codebase. * There is no particular reason for these examples to be gendered. * `man` is hard to grep for, since it also matches `many, manager, manual, etc` For the most part this is a simple search and replace. The one exception to that is that I had to add the table name to the model so we could use "humans" instead of "humen".

Don't run callbacks on has_many inverse add Stop running association callbacks when setting `has_many` inverse records. The `before_add` and `after_add` callbacks are meant for newly added records.
