Rails: around_* callbacks
The around_* callback is called around the action and inside the before_* and after_* actions. For example:
class User
def before_save
puts 'before save'
end
def after_save
puts 'after_save'
end
def around_save
puts 'in around save'
yield # User saved
puts 'out around save'
end
end
User.save
before save
in around save
out around save
after_save
=> true
around_*
callbacks are invoked before the action, then when you want to invoke the action itself, you yield
to it, then continue execution. That's why it's called around
The order goes like this: before
, around
, after
.
So, a typical around_save
would look like this:
def around_save
#do something...
yield #saves
#do something else...
end
