我正在尝试在帮助程序模块中创建一个登录操作，该操作将创建一个新用户并以该用户身份登录。由于我使用capybara与capybara-webkit驱动程序，post或submit方法不可用，所以我不能简单地使用适当的参数发布到登录路径。我当前的方法是实际访问登录路径并使用新创建的用户的用户名和密码填写登录表单。这是我正在尝试创建的辅助函数（在spec / support / session_macros.rb中）：
module SessionMacros
def log_in
user = User.create(first_name: 'Test',
last_name: 'Test',
email: 'foo@example.com',
password: 'secret',
password_confirmation: 'secret'
)
visit admin_login_path
fill_in 'email', with: user.email
fill_in 'password', with: 'secret'
click_button 'Log in'
end
end
在spec / spec_helper.rb中：
config.include SessionMacros
在config / routes.rb中：
namespace :admin do
resources :sessions
get 'login', to: 'sessions#new', as: 'login'
get 'logout', to: 'sessions#destroy', as: 'logout'
end
在app / views / admin / sessions / new.html.haml
中.login-form
%h3 Sign in
= form_tag admin_sessions_path do
= content_tag :div, flash[:alert], class: 'alert' if flash[:alert]
= text_field_tag :email, params[:email], placeholder: 'Email'
= password_field_tag :password, params[:password], placeholder: 'Password'
= submit_tag "Log in", class: 'button'
在app / controllers / admin / sessions_controller.rb
中def create
user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])
session[:user_id] = user.id
redirect_to admin_root_url
else
flash[:alert] = 'Invalid email or password'
redirect_to admin_login_path
end
end
我正在使用功能规范中的帮助程序（spec / features / admin / events_spec.rb）：
before :each do
log_in
visit admin_events_path
end
问题在于我运行的测试：js =＆gt; true将导致sessions_controller #create函数无法查看在log_in方法开头创建的用户。这是我做过的一些控制台测试的结果：
[5, 14] in /Users/Me/projects/cms/spec/support/session_macros.rb
5 email: 'foo@example.com',
6 password: 'secret',
7 password_confirmation: 'secret'
8 )
9 debugger
=> 10 visit admin_login_path
11 fill_in 'email', with: user.email
12 fill_in 'password', with: 'secret'
13 click_button 'Log in'
14 end
(rdb:1) User.all
[#<User id: 1, email: "foo@example.com", password_digest: "$2a$10$Pxv3GlNnEPx0PnFOmP/MUeP0SMs4vD925vjhoaViKA8o...", created_at: "2013-12-29 20:34:47", updated_at: "2013-12-29 20:34:47", first_name: "Test", last_name: "Test">]
(rdb:1) continue
/Users/Me/projects/cms/app/controllers/admin/sessions_controller.rb:7
if user && user.authenticate(params[:password])
[2, 11] in /Users/Me/projects/cms/app/controllers/admin/sessions_controller.rb
2 skip_before_filter :authorize, :authenticate
3
4 def create
5 user = User.find_by_email(params[:email])
6 debugger
=> 7 if user && user.authenticate(params[:password])
8 session[:user_id] = user.id
9 redirect_to admin_root_url
10 else
11 flash[:alert] = 'Invalid email or password'
(rdb:6) User.all
[]
(rdb:6)
请注意，当我不使用时：js =＆gt;是的，它工作正常：
[5, 14] in /Users/Me/projects/cms/spec/support/session_macros.rb
5 email: 'foo@example.com',
6 password: 'secret',
7 password_confirmation: 'secret'

当我使用Selenium和webkit驱动程序进行javascript时，会发生这种情况。什么给这里？我担心在与Capybara进行JS集成测试时，我可能会从根本上误解数据库交互。我也担心这可能是一个XY问题，因为我甚至不确定我的log_in方法方法。如果有人能够更好地实现我可以与Javascript兼容的log_in助手，或者为什么我的数据库对象无法在Javascript模式的控制器中找到，我真的很感激。
