ActiveRecord::RecordNotSaved can be triggered by accidental false return values in callbacks

tadman · Jun 3, 20099 thanks

You may have this exception raised if any of the defined callbacks such as ActiveRecord::Base#before_save or ActiveRecord::Base#before_create return false.

This can happen accidentally. For example:

class MyModel < ActiveRecord::Base
before_save :assign_default_foo

protected
def assign_default_foo
  self.foo = false
end
end

Since assign_default_foo leaves a false value on the stack, the model will not be saved. A way around this is to simply leave nil or an empty return instead:

class MyModel < ActiveRecord::Base
before_save :assign_default_foo

protected
def assign_default_foo
  self.foo = false
  nil
end
end
