i'm using rails 5.1.5, and default testing library, so when i try to test my show action in posts contoller, i get an error:
Error:
PostsControllerTest#test_should_show_post:
ActionController::UrlGenerationError: No route matches
{:action=>"show", :controller=>"posts"}, missing required keys: [:id]
here is My posts_controller_test.rb
require 'test_helper'
class PostsControllerTest < ActionDispatch::IntegrationTest
test "should get index" do
get posts_url, params: { keywords: "" }
assert_response :success
end
test "should show post" do
post = posts(:post)
get post_url, params: {id: post.id}
assert_response :success
end
end
Here is my post fixture file posts.yml
post:
title: testpost
body: lorem ipsum
user: tom
routes.rb
Rails.application.routes.draw do
root "posts#index"
devise_for :users
resources :posts do
resources :comments
end
resources :users, except: [:create, :new]
resources :tags, only: [:show, :create]
end
posts_controller.rb
class PostsController < ApplicationController
before_action :set_post, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]
before_action :check_owner, only: [:destroy, :edit, :update]
def index
@posts = Post.search(params[:keywords]).uniq
end
def show
#set_post
end
def new
@post = Post.new
end
def create
@post = Post.new(post_params)
# link the post to user that logged in atm
@post.user = current_user
if @post.save
# redirect to created post and show flash
redirect_to @post, success: "Post successfully created !"
else
render :new
end
end
def edit
#set_post
#check_owner
end
def update
#set_post
#check_owner
if @post.update_attributes(post_params)
# redirect to updated post and show flash
redirect_to @post, success: "Post successfully updated !"
else
render :edit
end
end
def destroy
#set_post
#check_owner
@post.destroy
# redirect to root and show flash
redirect_to posts_path, success: "Post successfully deleted !"
end
private
def set_post
@post = Post.find(params[:id])
end
# strong params
def post_params
params.require(:post).permit(:title, :body, :image, :image_cache, :status, :adress, :current_tags)
end
def check_owner
#check if current user is owner of the post
redirect_to @post, alert: "You are not the owner of this post" unless current_user == @post.user || current_user.admin?
end
end
and finally my test console
