PG::Error: ERROR: relation "users" does not exist

sorry for disturb you but i have a lot of question about this error. first this is my user_controller rspec file require 'spec/spec_helper' ``` describe UserController do it "create new user" do post "create" assigns[:users].should_not be_new_record end end ``` this is my UserController ``` class UserController < ApplicationController def create @users = User.new if @users.save flash[:notice] = 'new user was successfully created.' else render :action => :new end end def new @user = User.new end end ``` and my routes.rb (i think the problem is here, excuse me but i`m new in this language) ``` Estaciones::Application.routes.draw do devise_for :users root :to => "home#index" resources :user end ``` when i try to test my user_controller_rspec then i get this error Failures: ``` 1) UserController create new user Failure/Error: post "create" ActiveRecord::StatementInvalid: PG::Error: ERROR: relation "users" does not exist LINE 4: WHERE a.attrelid = '"users"'::regclass ^ : SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attrelid = '"users"'::regclass AND a.attnum > 0 AND NOT a.attisdropped ORDER BY a.attnum # ./app/controllers/user_controller.rb:3:in `new' # ./app/controllers/user_controller.rb:3:in `create' # ./spec/controllers/user_controller_spec.rb:6 Finished in 0.01722 seconds 1 example, 1 failure Failed examples: rspec ./spec/controllers/user_controller_spec.rb:5 # UserController create new user ``` how i can fix it... thanks
