copied!<p>I am trying to figure out how to write the show action for Form Objects.</p> <p>The following is code taken from RailsCast episode 416 <a href="https://github.com/railscasts/416-form-objects/tree/master/signup-after" rel="nofollow">project</a></p> <p><strong>app/forms/signup_form.rb</strong></p> <pre><code>class SignupForm # Rails 4: include ActiveModel::Model extend ActiveModel::Naming include ActiveModel::Conversion include ActiveModel::Validations def persisted? false end def self.model_name ActiveModel::Name.new(self, nil, "User") end validates_presence_of :username validate :verify_unique_username validates_format_of :email, with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/ validates_length_of :password, minimum: 6 delegate :username, :email, :password, :password_confirmation, to: :user delegate :twitter_name, :github_name, :bio, to: :profile def user @user ||= User.new end def profile @profile ||= user.build_profile end #... end </code></pre> <p><strong>app/controllers/users_controller.rb</strong></p> <pre><code>class UsersController < ApplicationController def new @signup_form = SignupForm.new end def create @signup_form = SignupForm.new if @signup_form.submit(params[:user]) session[:user_id] = @signup_form.user.id redirect_to @signup_form.user, notice: "Thank you for signing up!" else render "new" end end def show @user = current_user end end </code></pre> <p>I don't see how one would pass in the ID of the model and specify the variables.</p> <p>Does anyone have an example or can provide one using the episode's code as a starting point?</p>
