Question

我有一个视图文件_edit.html.erb

 <%= form_for(@search_phrase, remote: true) do |f| %>
   <h4> Keyword </h4>
   <%= f.text_field :keyword %><br/>
   <%= f.submit "Add", class: "btn btn-medium btn-primary" %>
   <%= render 'error' %>
 <% end %>

我正在为它编写视图rspec测试/我的测试在_edit.html.erb_spec.rb中是这样的

describe "search_phrases/_edit.html.erb" do
  include Devise::TestHelpers
  User.destroy_all

  before :all do
    @user = User.find_by_name('testuser')
    @user ||= begin
    user = User.new(email: "test@gmail.com",
    encrypted_password: "$2a$10$TIJrH0tmQ7VuDeBVBIYhJ......................",
    provider: "facebook", uid: "10000697585", name: "testuser",
    fb_token: "AUExuiUkFoBAEsYdxTfU1ONYanI55Sx5ThBTjo7qnKLiZ")
    user.save!
    user
  end
end

before  :each do
  User.stub(:find_for_facebook_oauth).and_return(@user)
  sign_in @user
end

before :all do
  @search_phrase = SearchPhrase.find_by_user_id(@user.id)
  @search_phrase ||= begin
    search_phrase= SearchPhrase.new(keyword: "testkeyword",user_id: @user.id) #never hard code
    search_phrase.save!
    search_phrase
  end
end

it "creates a form" do
    render
    rendered.should_receive(:form_for).with edit_search_phrase_path(@search_phrase)   
  end
end

但是测试没有给出错误

search_phrases/_edit.html.erb creates a form
     Failure/Error: render
     ActionView::Template::Error:
       undefined local variable or method `search_phrase' for #<#<Class:0x000000073080c0>:0x00000007371b38>

这里有什么问题，我无法弄明白。

Answer 1

您可能错过了路线

#in routes.rb
 resources :search_phrases
 ...

Answer 2

您需要添加 assign(:search_phrase, @search_phrase) 在before :all区块。即。

before :all do
  @search_phrase = SearchPhrase.find_by_user_id(@user.id)
  @search_phrase ||= begin
   search_phrase= SearchPhrase.new(keyword: "testkeyword",user_id: @user.id) #never hard code
   search_phrase.save!
   search_phrase
  end
  assign(:search_phrase, @search_phrase
end
