找不到未禁用的字段“ player_1_name”

Question

我只是通过演练开始了这段代码。我的功能测试应该可以正常工作，但是它给了我这个错误：

Unable to find field "player_1_name" that is not disabled

我尝试使用[]更改引号，路径，但仍然给我相同的错误。

• 我的红宝石版本。 红宝石2.6.3p62（2019-04-16修订版67580）[x86_64-darwin18]
• 此外，除了Rspec和水豚以外，我还在使用shot弹枪，sinatra。 在下面的代码中，我将指定每个代码是哪个文件。

#features/entre_names_spec.rp

feature "Enter names" do
  scenario "submitting names" do
    visit('/')
    fill_in "player_1_name", with: 'Dave'
    fill_in "player_2_name", with: 'Mittens'
    click_button 'Submit'
    expect(page).to have_content 'Dave vs. Mittens'
  end
end

#app.rb
require 'sinatra/base'

class Battle < Sinatra::Base
  get '/' do
    'Testing infrastructure working!'
  end

  get '/' do
    erb :index
  end

  post '/names' do
    @player_1_name = params[:player_1_name]
    @player_2_name = params[:player_2_name]
    erb :play
  end

  # start the server if ruby file executed directly
  run! if app_file == $0
end

views/index.erb
<form action= "names" method= "post">
  <input type= "text" name= "player_1_name">
  <input type= "text" name= "player_2_name">
  <input type= "submit" value= "Submit">
</form>

#views/play.erb
<%= @player_1_name %> vs. <% @player_2_name %>

我的猜测是，如果您访问根路径，则会看到Testing infrastructure working!。这是因为get '/'被定义了两次，在我的Sinatra版本（v2.0.5）中，第一个声明获胜。

这是呈现该表单的此服务器的简单版本。它应该通过测试：

# app.rb

require 'sinatra'

# get '/' defined once
get '/' do
  erb :index
end

post '/names' do
  @player_1_name = params[:player_1_name]
  @player_2_name = params[:player_2_name]
  erb :play
end

运行方式：

$ ruby app.rb

注意事项：您还必须在播放视图中添加第二个等号，因此ERB知道@player_2_name是Ruby表达式。

# views/play.erb

<%= @player_1_name %> vs. <%= @player_2_name %>
