Question

Noob在这里，让我从我做了什么以及为什么做起：客户端和护理人员（具有不同角色的用户）使用用户模型。我做了脚手架，用--skip-migration生成客户端和看护人，然后删除了自动生成的模型（Client.rb和Caregiver.rb），并在生成的控制器和视图中将Client替换为User。

一切似乎都运转良好，但我认为这似乎只是。在我测试视图时，我收到以下错误：

 Minitest::Assertion:
       Expected at least 1 element matching "form[action="/clients/1"][method="post"]", found 0..
       Expected 0 to be >= 1.

以下是其他相关文件的内容：

控制器/ clients_controller

class ClientsController < ApplicationController

  # GET /clients/1/edit
  def edit
  end
end

规格/视图/客户端/ edit_spec

require 'rails_helper'

RSpec.describe "clients/edit", type: :view do
  before(:each) do
      @client = FactoryGirl.create :client_user   
  end

  it "renders the edit client form" do
    render

    assert_select "form[action=?][method=?]", client_path(@client), "post" do
    end
  end
end

视图/客户端/ edit.html.haml

%h1 Editing client

= render 'form'

= link_to 'Show', @client
\|
= link_to 'Back', clients_path

视图/客户端/ _form.html.haml

= form_for @client do |f|
  - if @client.errors.any?
    #error_explanation
      %h2= "#{pluralize(@client.errors.count, "error")} prohibited this client from being saved:"
      %ul
        - @client.errors.full_messages.each do |msg|
          %li= msg

  .actions
    = f.submit 'Save'

删除现有型号时是否遗漏了任何内容？或者我该怎么办？一个型号和多个控制器。如果需要任何其他文件？

P.S - 我没有触及过rails生成的视图。

有趣的是，你正在用rspec编写你的规范，虽然有minitest的错误，之前从未做过那种组合，但你确定你正在运行正确的测试吗？使用rspec，您应该使用bundle exec rspec

运行测试

其次，您需要将FactoryGirl创建的此对象分配给视图中的实例变量

需要'rails_helper'

describe 'clients/edit' do
  let(:client) { FactoryGirl.create(:client_user) } # Prefer using let instead of before each, why? in case you make typo in `@client` you are going to get "nil" error, if you are going to make typo in `client` you are going to get Unknown Attribute/Method error. There are more advantages to it you can read about this in rspec documentation at https://www.relishapp.com/rspec/rspec-rails/docs

  before do # before and before(:each) are basically the same
    assign(:client, client) # now you need to assign instance variable in view so those are the same when you are doing the assertion below
    render # render the view
  end

  it 'renders the edit client form' do
    render

    assert_select "form[action=?][method=?]", client_path(client), "post" do


    end

    # Rspec way
    expect(rendered).to have_css('css selector goes here')
  end
end

而且，顺便说一下，你的控制器中不需要空方法edit，rails会查找视图文件，所以如果你的文件夹中有edit。*文件，那么没有这个丑陋的空方法就可以了

Rspec错误：预计至少有1个元素匹配“form [action =”/ clients / 1“] [method =”post“]”，找到0
