Question

Well, I don’t know if I’m completely wrong, but I really can’t find a very practical and straight forward way to do something like this:

class User < ActiveRecord::Base

has_many :creations

end

but the thing is, I just want the user to have many creations if the user.developer == true
where user.developer is just a boolean field inside the Users table.

So any ideas on how exactly could I do it directly from the model?

Resuming, when the user is not a developer if you try to get User.first.creations, User.first.creations.new … create…destroy, etc you get a NoMethodError but if it is a developer you can build a new creation.

The only way I managed to do it is extending the model and from the extension check if the proxy_owner.developer == true but by doing this I had to rewrite all the actions such new, create, update, etc…

Any help would be much appreciated
Thanks a lot

Answer 1

How about subclassing User and only specifying the has_many on the developer subclass? Developer would then pick up any logic from User and Users wouldn’t have any creations.

class User < ActiveRecord::Base
end

class Developer < User
  has_many :creations
end
