[英]Testing a general controller action using rspec
Here's how my routes look like: 这是我的路线的样子:
/article/:id/:action {:root=>"article", :controller=>"article/article", :title=>"Article"}
Here's how my controller looks like: 这是我的控制器的样子:
# app/controllers/article/article_controller.rb
class ArticleController < ApplicationController
def save_tags
# code here
end
end
I want to test the save_tags action so I write my spec like this: 我想测试save_tags动作,所以我写这样的规范:
describe ArticleController do
context 'saving tags' do
post :save_tags, tag_id => 123, article_id => 1234
# tests here
end
end
But when I run this spec, I get the error 但是当我运行这个规范时,我得到了错误
ActionController::RoutingError ...
No route matches {:controller=>"article/article", :action=>"save_tags"}
I think the issue is the save_tags action is a general controller action, ie. 我认为问题是save_tags动作是一般控制器动作,即。 there's no /article/:id/save_tags in routes.
路线中没有/ article /:id / save_tags。 What's the best way to test this controller action?
测试此控制器操作的最佳方法是什么?
You're spot on. 你是现货。 The issue is that you're looking for a route which doesn't have
:id
in it, but you don't have one. 问题是你正在寻找一条没有
:id
的路线,但你没有。 You'll need to pass a parameter to the post :save_tags
of :id
, and given the above question, I believe it is what you are calling article_id
. 你需要将一个参数传递给
post :save_tags
:id
,并且给出上述问题,我相信你正在调用article_id
。
Therefore, try changing your test to: 因此,请尝试将测试更改为:
describe ArticleController do
context 'saving tags' do
post :save_tags, tag_id => 123, id => 1234
# tests here
end
end
Update 更新
Rails might be getting confused because you're using :action
in your route and I believe action
is either a reserved word or a word that Rails treats as special. Rails可能会因为你在你的路线中使用
:action
而感到困惑,我相信action
要么是保留的单词,要么是Rails认为特殊的单词。 Maybe try changing your routes to: 也许尝试将您的路线更改为:
/article/:id/:method_name {:root=>"article", :controller=>"article/article", :title=>"Article"}
And your test to: 你的测试:
describe ArticleController do
context 'saving tags' do
post :save_tags, { :tag_id => 123, :article_id => 1234, :method_name => "save_tags" }
# tests here
end
end
You need a route to map to your controller actions 您需要一个映射到控制器操作的路径
post '/article/:id/save_tags'
should work, or consider using resources helper to build your routes 应该工作,或考虑使用资源助手来建立你的路线
# creates the routes new, create, edit, update, show, destroy, index
resources :articles
# you can exclude any you do not want
resources :articles, except: [:destroy]
# add additional routes that require an article in the member block
resources :articles do
member do
post 'save_tags'
end
end
# add additional routes that do NOT require an article in the collection block
resources :articles do
collection do
post 'publish_all'
end
end
