Some validations are repetitive in my models:
validates :name, :length => { :minimum => 2 }, :presence => true, :uniqueness => true
validates :name_seo, :length => { :minimum => 2 }, :presence => true, :uniqueness => true
How would I put that in a mixin? I get this error if I just put 'em in a mixin
app/models/validations.rb:5: undefined method `validates' for Validations:Module (NoMethodError)
Your module should look something like this:
module CommonValidations
extend ActiveSupport::Concern
included do
validates :name, :length => { :minimum => 2 }, :presence => true, :uniqueness => true
validates :name_seo, :length => { :minimum => 2 }, :presence => true, :uniqueness => true
end
end
Then in your model:
class Post < ActiveRecord::Base
include CommonValidations
...
end
I'm using ActiveSupport::Concern here to make the code a little clearer.
