Post[date]：：ElementNotFound:无法找到未禁用的可见字段“”

Question

我有一个集成测试，它给我的错误似乎与fill_in有关。

require 'rails_helper'

describe 'navigate' do
  let(:user) {FactoryGirl.create(:user)}

  let(:post) do
    Post.create(date: Date.today, rationale: "Rationale", user_id: user.id)
  end

  before do
    login_as(@user, :scope => :user)
  end

  describe 'index' do
    before do
      visit posts_path
    end
    it 'can be reached successfully' do
      expect(page.status_code).to eq(200)
    end

    it 'has a title of Posts' do
      expect(page).to have_content(/Posts/)
    end

    it 'has a list of posts' do
      post1 = FactoryGirl.build_stubbed(:post)
      post2 = FactoryGirl.build_stubbed(:second_post)
      visit posts_path
      expect(page).to have_content(/Rationale|content/)
    end

    it 'has a scope so that only post creators can see their posts' do
      other_user = User.create(first_name: 'Non', last_name: 'Authorized', email: 'nonauth@example.com',
                                          password: "password", password_confirmation: "password")

      post_from_other_user = Post.create(date: Date.today, rationale: "This post shouldn't be seen",
                                          user_id: other_user.id)

      visit posts_path

      expect(page).to_not have_content(/This post shouldn't be seen/)
    end
  end

  describe 'new' do
    it "has a link from the homepage" do
      visit root_path

      click_link("new_post_from_nav")
      expect(page.status_code).to eq(200)
    end
  end

  describe 'delete' do
    it 'can be deleted' do
      logout(:user)

      delete_user = FactoryGirl.create(:user)
      login_as(delete_user, :scope => :user)

      post_to_delete = Post.create(date: Date.today, rationale: 'rationale', user_id: delete_user.id)

      visit posts_path

      click_link("delete_post_#{post_to_delete.id}_from_index")
      expect(page.status_code).to eq(200)
    end
  end

  describe 'creation' do
    before do
      visit new_post_path
    end

    it 'has a new form that can be reached' do
      expect(page.status_code).to eq(200)
    end

    it 'can be created from a new form page' do
      fill_in 'post[date]', with: Date.today
      fill_in 'post[rationale]', with: "Some rationale"
      click_on "Save"

      expect(page).to have_content("Some rationale")
    end

    it 'will have a user associated with it' do
      fill_in 'post[date]', with: Date.today
      fill_in 'post[rationale]', with: "User Association"
      click_on "Save"

      expect(User.last.posts.last.rationale).to eq("User Association")
    end
  end

  describe 'edit' do

    it "can be edited" do
      visit edit_post_path(post)

      fill_in 'post[date]', with: Date.today
      fill_in 'post[rationale]', with: "Edited content"
      click_on "Save"

      expect(page).to have_content("Edited content")
    end

    it "cannot be edited by a non authorized user" do
      logout(:user)
      non_authorized_user = FactoryGirl.create(:non_authorized_user)
      login_as(non_authorized_user, :scope => :user)

      visit edit_post_path(post)

      expect(current_path).to eq(root_path)
    end
  end
end

我查看视图/post/_form.html.erb文件：

<%= form_for @post, class: "form-horizontal" do |f| %>
  <% if @post.errors.any? %>
    <% @post.errors.full_messages.each do |error| %>
      <%= js add_gritter(error, title: "Overtime App Notification", sticky: false, image: :notice) %>
    <% end %>
  <% end %>

  <div class="form-group">
    <%= f.label :date, class: "col-sm-2 control-label" %>
    <%= f.date_field :date, class: "form-control" %>
  </div>

  <div class="form-group">
    <%= f.label :rationale, class: "col-sm-2 control-label" %>
    <%= f.text_area :rationale, class: "form-control" %>
  </div>

  <%= render partial: 'status', locals: {f: f} if current_user.type == 'AdminUser' %>

    <%= f.submit 'Save', class: 'btn btn-primary btn-block' %>
<% end %>

我不知道这里出了什么问题。如果我检查元素，它就在那里：

​

​

这是我的post.rb模型文件：

class Post < ActiveRecord::Base
  enum status: {submitted: 0, approved: 1, rejected: 2}
  belongs_to :user
  validates_presence_of :date, :rationale

  scope :posts_by, ->(user) {where(user_id: user.id)}
end

测试昨天通过了，不知道发生了什么。

Answer 1

1. 您正在用@user调用@user，但是@user从来没有定义过，您可能需要login_as(user)。
2. 总是尝试着回溯你的步骤，如果有什么东西以前起作用了，想想在上次工作到它开始失败之间你引入了什么代码。
3. 检查状态代码通常是特性测试的难闻之处，只需检查用户可以看到的内容。
4. 不要将eq匹配器与current_path一起使用，而是使用Capybara提供的have_current_path匹配器。
