Rails skip_callback with if condition not working

Question

I have the line below in one of my models:

skip_callback :create, :after, :creation_email, if: -> { self.template_email }

template_email is a method in the model, that based on associated data will return true or false. The method is returning true, but the callback is not being skipped.

Answer 1

In Rails 4 :

after_create :creation_email, if: :template_email #execute if true
after_create :creation_email, unless: :template_email #skip if true

Something this way it can be done. Here creation_email is invoked when template_email method returns true otherwise skips invoking.
