我对 Ruby & Rails 还很陌生;没有做太多编程;但有技术背景。

我已经构建了非常少量的功能,主要基于 Railscasts,并且想要使用 TDD,并且在继续前进之前,我会回去尝试构建一些简单的测试。

我被困在一个视图的测试中,找不到任何类似的东西来弄清楚如何解决这个问题。我浏览了 Railscasts、The RSpec book 等,并进行了很多搜索。

所需的功能似乎工作正常,但测试失败。

任何帮助或方向表示赞赏。

错误:

 Failure/Error: render
 ActionView::Template::Error:
   No route matches {:action=>"show", :controller=>"email_verifies", :id=>nil}
 # ./app/views/email_verifies/edit.html.haml:3:in `_app_views_email_verifies_edit_html_haml__3756516833416545914_70345184965780'
 # ./spec/views/email_verifies/edit.html.haml_spec.rb:6:in `block (2 levels) in <top (required)>'

代码:

应用程序/视图/email_verifies/edit.html.haml

%h1 Verify Email Address

= form_for @user, :url => email_verify_path(params[:id]) do |f|

  .actions
    = f.submit "Verify Email Address"

规范/视图/email_verifies/edit.html.haml_spec.rb

require 'spec_helper'

describe "email_verifies/edit.html.haml" do
  let(:user) { FactoryGirl.create(:user, :email_verify_token => "anything") }
  it "displays the text on the rendered page" do
    render
    rendered.should have_content("Verify Email Address")
  end
end

规格/工厂/factories.rb

FactoryGirl.define do
  factory :user do
    sequence :email do |n|
      "foo#{n}@example.com" 
    end
    password "secret"
  end
end

app/controllers/email_verifies_controller.rb 的一部分(此控制器中没有“显示”操作)

def edit
  @user = User.find_by_email_verify_token(params[:id])
  unless @user
    redirect_to signup_path, :alert => "This email verification has expired.  Please sign up again."
  end
end

部分路线:

edit_email_verify GET    /email_verifies/:id/edit(.:format)  email_verifies#edit  
     email_verify GET    /email_verifies/:id(.:format)       email_verifies#show  
email_verifies    GET    /email_verifies(.:format)           email_verifies#index  
edit_email_verify GET    /email_verifies/:id/edit(.:format)  email_verifies#edit  
     email_verify GET    /email_verifies/:id(.:format)       email_verifies#show  
                  PUT    /email_verifies/:id(.:format)       email_verifies#update

我对这种语法有点不熟悉,但是基于错误,我认为问题出在:

  it "displays the text on the rendered page" do
    render #HERE!
    rendered.should have_content("Verify Email Address")
  end

无论如何,问题在于编辑操作(我认为,您在这里尝试测试的内容)需要一个:id,因此它知道要编辑的电子邮件 - 检查输出rake routes

edit_email_verify GET    /email_verifies/:id/edit(.:format) 

您需要:id在该渲染调用中包含一个 - 这可能有效:

改变

it "displays the text on the rendered page" do
  render
  rendered.should have_content("Verify Email Address")
end

it "displays the text on the rendered page" do
  render edit_email_verify_path(@user) #the @user might need to be changed 
                                       #depending on what the `:id` refers to
  rendered.should have_content("Verify Email Address")
end

更新

我刚试render edit_email_verify_path(:id => user.email_verify_token)了,好像是通过了:id,然后就报错了

ActionView::MissingTemplate: Missing partial /email_verifies/anything/edit with {:locale=>[:en], :formats=>[:html, :text, :js, :css, :ics, :csv, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :handlers=>[:erb, :builder, :coffee, :haml]} 

以前应该看到过这个,但问题出在这里:

Missing partial /email_verifies/****anything****/edit

:idin/email_verifies/:id/edit是用户,:id所以你应该尝试

render edit_email_verify_path(user)

这将返回/email_verifies/[your users id]/edit
