Tôi có ứng dụng Rails (Rails 3.0.10) nơi người dùng có thể có nhiều bài viết và nơi người dùng có thể để lại nhận xét về bài viết. Nhận xét được thực hiện trên trang hiển thị bài viết.Kiểm tra RSpec để tạo hành động của bộ điều khiển cho tài nguyên lồng nhau
Bây giờ tôi muốn thử nghiệm hành động tạo của CommentController, tuy nhiên, tôi có vấn đề về cách gọi phương thức bài với các tham số đúng.
Dưới đây là đoạn code của CommentsController:
class CommentsController < ApplicationController
# create a comment and bind it to an article and a user
def create
@article = Article.find(params[:article_id])
@user = User.find(@article.user_id)
@comment = @article.comments.build(params[:comment])
@comment.user_id = current_user.id
commenters = []
@article.comments.each {
|comment|
commenters << User.find(comment.user_id)
}
commenters.uniq!
respond_to do |format|
if @comment.save
#Notify user who offers article on new comment, else notify the commenters
if @article.user_id != @comment.user_id
UserMailer.new_article_comment_email(@user, @comment).deliver
else
commenters.each {
|commenter|
UserMailer.new_article_comment_email(commenter, @comment).deliver
}
end
format.html {
redirect_to(@article)
flash[:notice] = t(:comment_create_success)
}
else
format.html {
redirect_to(@article)
flash[:error] = t(:comment_create_error)
}
end
end
end
end
Mã RSpec để thử nghiệm hành động này (một số thí nghiệm cho đến nay) như sau:
require 'spec_helper'
require 'ruby-debug'
describe CommentsController do
render_views
describe "POST 'create'" do
before(:each) do
@user = FactoryGirl.create(:user)
@article = FactoryGirl.build(:article)
@article.user_id = @user.id
@article.save
@article_attributes = FactoryGirl.attributes_for(:article)
@comment_attributes = FactoryGirl.attributes_for(:comment)
end
it "should create a new comment" do
expect {
post :create, :comment => @comment_attributes
}.to change(Comment, :count).by(1)
end
it "should create a new comment, redirect to the article show page of this comment and notify the user on successful saving of the comment" do
post :create, :comment => @comment_attributes, :article_id => @article.id.to_s, :user_id => @user.id.to_s
flash[:notice].should_not be_nil
response.should redirect_to(article_path(@article))
end
end
end
Cả hai thử nghiệm thất bại, tuy nhiên, do các lý do khác nhau mà tôi không thể khắc phục:
Failures:
1) CommentsController POST 'create' should create a new comment
Failure/Error: post :create, :comment => @comment_attributes
ActionController::RoutingError:
No route matches {:comment=>{:body=>"This is the body text of a comment"}, :controller=>"comments", :action=>"create"}
# ./spec/controllers/comments_controller_spec.rb:22:in `block (4 levels) in <top (required)>'
# ./spec/controllers/comments_controller_spec.rb:21:in `block (3 levels) in <top (required)>'
2) CommentsController POST 'create' should create a new comment, redirect to the article show page of this comment and notify the user on successful saving of the comment
Failure/Error: post :create, :comment => @comment_attributes, :article_id => @article.id.to_s, :user_id => @user.id.to_s
RuntimeError:
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
# ./app/controllers/comments_controller.rb:8:in `create'
# ./spec/controllers/comments_controller_spec.rb:27:in `block (3 levels) in <top (required)>'
Tôi sẽ rất tuyệt nếu ai đó có thể giúp tôi. Cảm ơn trước!
Cập nhật: Đây là routes.rb Tôi đang sử dụng:
Cinderella::Application.routes.draw do
# The priority is based upon order of creation:
# first created -> highest priority.
# Sample of regular route:
# match 'products/:id' => 'catalog#view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
# This route can be invoked with purchase_url(:id => product.id)
match '/signup', :to => 'users#new'
match '/signin', :to => 'sessions#new'
match '/signout', :to => 'sessions#destroy'
match '/home', :to => 'pages#home'
match '/about', :to => 'pages#about'
match '/faq', :to => 'pages#faq'
match '/howitworks_sellers', :to => "pages#howitworks_sellers"
match '/howitworks_buyers', :to => "pages#howitworks_buyers"
match '/contact', :to => 'pages#contact'
match '/articles/:id/ratings', :to => 'ratings#destroy'
# Sample resource route (maps HTTP verbs to controller actions automatically):
# resources :products
resources :articles do
resources :comments, :only => [:create, :destroy]
end
resources :ratings
resources :ratings do
collection do
post 'destroy'
end
end
resources :users do
resources :articles
end
resources :sessions, :only => [:new, :create, :destroy]
# Sample resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Sample resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Sample resource route with more complex sub-resources
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', :on => :collection
# end
# end
# Sample resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
root :to => "pages#home"
# See how all your routes lay out with "rake routes"
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
# match ':controller(/:action(/:id(.:format)))'

Cập nhật: Đây là việc sửa đổi Tôi đã theo nmotts gợi ý:
require 'spec_helper'
require 'ruby-debug'
describe CommentsController do
render_views
describe "POST 'create'" do
before(:each) do
@user = FactoryGirl.create(:user)
@article = FactoryGirl.build(:article)
@article.user_id = @user.id
@article.save
@comment_attributes = FactoryGirl.attributes_for(:comment, :article_id => @article)
end
it "should create a new comment" do
post :create, :article_id => @article.id.to_s, :comment => @comment_attributes
end
end
end
Và định nghĩa FactoryGirl bình luận:
factory :comment do
body "This is the body text of a comment"
article
end
Thật không may, mã chưa hoạt động.
