Hello everybody, I have this problem (title of the post). ``` Failure/Error: get :create, :user => { :email => 'foo@example.com', :name => 'userexample' } ActionController::RoutingError:No route matches {:action=>"show", :controller=>"user", :id=>nil} ``` Here is my `UserController`. ``` class UserController < ApplicationController def new end def create @user = User.new(params[:user]) @user.save redirect_to :action => :show, :id => @user.id end def show @user = User.find(params[:id]) end end ``` Here is my routes.rb ``` ::Application.routes.draw do devise_for :users root :to => "user#index" resources :user #match "newuser" => "user#new" get "user/new" post "user/create" get "user/:id" => "user#show" ``` And here is my rspec test ``` require 'spec/spec_helper' describe UserController do it "create new user" do get :create, :user => { :email => 'foo@example.com', :name => 'userexample' } flash[:notice] = 'new user was successfully created.' end end end ```
