copied!<p>Here's my functioning code to register a type of user called mentor via a Rails 4 JSON API. </p> <p>Now I'm wondering, is there a better way to go about this? A more cleaner/simpler approach where Rails can automagically create the user/mentor association. </p> <p>Currently I'm setting it manually in the <code>create</code> method which doesn't seem right. So I just want to make sure there is no better way out there of going about this.</p> <p><strong>models/user.rb</strong></p> <pre><code>class User < ActiveRecord::Base # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable belongs_to :role, :polymorphic => true end </code></pre> <p><strong>models/mentor.rb</strong></p> <pre><code>class Mentor < ActiveRecord::Base has_one :user, as: :role accepts_nested_attributes_for :user end </code></pre> <p><strong>controllers/api/V1/mentors_controller.rb</strong></p> <pre><code>class Api::V1::MentorsController < ApplicationController respond_to :json def create @user = User.new(user_params) @mentor = Mentor.new(mentor_params) @user.role = @mentor @user.save! @mentor.user_id = @user.id @mentor.save! respond_with :api, @mentor end private def mentor_params params.require(:mentor).permit(:first_name, :last_name) end def user_params params.require(:user).permit(:email, :password) end end </code></pre> <p><strong>UPDATE - 10/01/2013</strong></p> <p>I make some more inroads with this. Here's what I have now:</p> <p><strong>controllers/api/V1/mentors_controller.rb</strong></p> <pre><code>class Api::V1::MentorsController < ApplicationController respond_to :json def create @mentor = Mentor.new(mentor_params) @mentor.user.save! @mentor.user_id = @mentor.user.id @mentor.save! respond_with :api, @mentor end private def mentor_params params.require(:mentor).permit(:first_name, :last_name, user_attributes: [:email, :password]) end end </code></pre> <p>But I still have to set the user_id manually. Only doing <code>Mentor.create(mentor_params)</code> fails to set the user_id. Any way to get around that?</p>
