Rails: create on has_one association

Question

Hi (huge Rails newbie here), I have the following models:

class Shop < ActiveRecord::Base   belongs_to :user   validates_uniqueness_of :title, :user_id, :message => "is already being used" end 

and

class User < ActiveRecord::Base   has_one :shop, :dependent => :destroy end 

When I'm about to create a new shop, I get the following error:

private method `create' called for nil:NilClass 

This is my controller:

@user = current_user @shop = @user.shop.create(params[:shop]) 

I've tried different variations by reading guides and tutorials here and there, but I'm more confused than before and can't get it to work. Any help would be greatly appreciated.

Answer 1

A more concise way to do this is with:

@user.create_shop(params[:shop]) 

See methods added by has_one in the Ruby on Rails guides.
