Capybara 不会填写表单字段（尽管它会找到它们）

Question

我正在使用 Ruby 2.2.1 和 Capybara 2.2.4 开发 Rails 4.2.1。编写规范来注册用户，Capybara 确实找到了字段（我没有收到 ElementNotFound 错误）但是当我尝试验证时我遇到了一个失败，所有字段都是空的并且在告诉 Capybara 单击注册之前也打开了 launchy按钮显示所有字段为空。

规格：

require 'rails_helper'

RSpec.feature "Sign Up Users", type: :feature do
  scenario "saves user to the database with valid data" do
    visit root_path
    click_link "Sign Up"

    find("#user_name").set("John Doe")
    fill_in "user_username", with: "johndoe"
    fill_in "user_email", with: "john@example.com"
    fill_in "user_password", with: "helloworld"
    fill_in "user_password_confirmation", with: "helloworld"

    save_and_open_page

    click_button "Create Account"

    expect(page).to have_text('Account successfully created! Welcome!')
    expect(page).to have_link('Log Out')
    expect(page).not_to have_link('Sign In')
    expect(page).not_to have_link('Sign Up')
  end

  scenario "does not save user with invalid data and re-renders sign up page" do
    visit root_path
    click_link "Sign In"

    click_link "Sign In"
    expect(page).to render(:signin)
  end
end

RSpec 错误：

Failures:

  1) Sign Up Users saves user to the database with valid data
     Failure/Error: expect(page).to have_text('Account successfully created! Welcome!')
       expected to find text "Account successfully created! Welcome!" in "Menu Sign In Sign Up TUDO | PRESENTES | FESTA | NOIVO | NOIVA Sign Up Please review the problems below: * Namecan't be blank * Usernamecan't be blank * Email * Password * Password confirmation Log in"

编辑：根据要求，表格 erb 模板：

  <div class="form-inputs">
    <%= f.input :name, required: true, autofocus: true %>
    <%= f.input :username, required: true %>
    <%= f.input :email, required: true %>
    <%= f.input :password, required: true, hint: ("#{@minimum_password_length} characters minimum" if @validatable) %>
    <%= f.input :password_confirmation, required: true %>
  </div>

我已设法修复它。它是由 Strong Params 和 Devise 引起的。我已将 Devise 设置为使用 name 和 username 参数，但它们未被授权，即使在控制器中明确清除也是如此。这是我所做的：

生成的设计控制器：

$ rails g devise:controllers
将新参数添加到 controllers/user/registrations_controller.rb:

#You can put the params you want to permit in the empty array.

def configure_account_update_params
  puts "configure_account_update_params"
  devise_parameter_sanitizer.for(:account_update) << :name
  devise_parameter_sanitizer.for(:account_update) << :username
end

将路由更改为首先通过此控制器而不是 routes.rb 中的默认 Devise 控制器：

devise_for :users, :controllers => { :registrations => "user/registrations" }
取消注释 registrations_controller.rb 中的第一行：

before_filter :configure_sign_up_params, only: [:create]

这不是 Capybara 的问题，而是 Devise with Strong Params 的问题。现在一切正常。

Capybara 不会填写表单字段（尽管它会找到它们）
