Rails - Best-Practice: How to create dependent has_one relations

Question

Could you tell me whats the best practice to create has_one relations?

f.e. if i have a user model, and it must have a profile...

How could i accomplish that

Answer 1

I had an issue with this and accepts_nested_attributes_for because if nested attributes were passed in, the associated model was created there. I ended up doing

after_create :ensure_profile_exists
has_one :profile
accepts_nested_attributes_for :profile


def ensure_profile_exists
  profile || create_profile
end
