undelete
: pretty self-explanatory, works only when soft deleting is enabledset_restriction
: use-case: controller’s constructor loads a model, adds a restriction (eg. “user_id = 123”), subsequent calls to the model add the restriction to all the queries. Think of it as an easy built-in security which removes the need to add the same where clause again and again on all methods.get_primary_value
: gets the current primary key value, useful in observersjoin
: performs a direct ActiveRecord joinwith
now accepts a second parameter which behaves like a with() inside the get()without_callbacks
: temporarly disable callbacks
