ruby-on-rails - capybara ::ElementNotFound:无法找到字段 "title"

Question

我无法解决这个问题。请帮我。它给我找不到元素的错误。

spec/features/todos/create_spec.rb

require 'spec_helper'

describe "Creating todos" do

 let(:user) { FactoryGirl.create(:user)}
 before(:each) do
   visit root_path
   click_link "Login"

   fill_in "Email",  with:  "user@gmail.com"
   fill_in "Password",  with: "password"
   click_button "Sign in"
 end

  it "redirects to the todos index page" do
   visit "/todos"

   fill_in "title", with: "MyString"
   click_button "Create"

   expect(page).to have_title("MyString")
 end

我的查看代码。_new_form.html.erb

     <%= form_for current_user.todos.new, remote:true  do |f| %>
       <div class="input-group">
         <%= f.text_field :title, class: "form-control",   placeholder: "title" %>
         <span class="input-group-btn">
         <%= f.submit "Create", class: "btn btn-success" %>
         </span>
       </div>
     <% end %>

spec_helper.rb

    def sign_in
      @user = FactoryGirl.create(:user)
      controller.stub(:authenticate_user!).and_return(true)
      @user
    end

如果您的代码在本地服务器上运行，请检查元素和字段名称是 Capybara 需要运行的内容。通常，如果表单是嵌套的，rails 的名称(在本例中)类似于 todos[title]。

因此，spec/features/todos/create_spec.rb 应该类似于:

require 'spec_helper'
 ...

it "redirects to the todos index page" do
 visit "/todos"

 fill_in "todos[title]", with: "MyString"
 click_button "Create"

 expect(page).to have_title("MyString")
end
