无法找到未禁用的字段 "player_1_name"

Question

我刚刚通过向我提供的演练开始这段代码。我的功能测试应该有效，但它给了我这个错误：

`Unable to find field "player_1_name" that is not disabled`

我试过使用 [] 更改引号、路径，但仍然出现同样的错误。

我的 ruby 版本。 ruby 2.6.3p62（2019-04-16 修订版 67580）[x86_64-darwin18]
此外，除了 Rspec 和水豚，我还使用 shotgun、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 == [=12=]
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 %>

Answer 1

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

这是呈现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

运行与：

$ ruby app.rb

警告：您还必须向播放视图添加第二个等号，以便 ERB 知道 @player_2_name 是一个 Ruby 表达式。

# views/play.erb

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

Answer 2

我遇到了这个问题。它说 'disabled' 因为 .erb 不在您目录中的正确位置。它应该保存在 'views' 文件夹中。
