Rails Nested Attributes Mass Assignment Error

I have a user model where I cannot create a client due to it being unwri开发者_StackOverflow中文版table in mass assignment.

How do I make it so that I can create a client model?

I think you have to add:

attr_accessible :client_attributes

to your user model. client_attributes is the hash in the user hash posted to the create action.

The transmitted hash looks something like this: :user => { :username => "one", ..., :client_attributes => { :name => "client" } }
