Adding Errors

[guizmaii]

I don't understand why when I write this in my interaction :

errors.add(:no_way)

and I have the following error :

NoMethodError - undefined method `no_way'

I need to write this :

errors.add(:no_way, 'no_way')

in order to correctly add an error.
The add_sym method has the same behavior.

This behavior actually comes from ActiveModel. In general, you can't add errors to an attribute that doesn't exist on a model. So this code will raise an error:

class Example < ActiveInteraction::Base
  def execute
    errors.add :no_way
  end
end
Example.run!

While this code won't:

class Example < ActiveInteraction::Base
  boolean :no_way
  def execute
    errors.add :no_way
  end
end
Example.run!

Ok. Thank you for the answer.
