Question

请帮助解决问题。

用帮助工具绑定用户工厂：

module Helpers
  def login_user
    @user = FactoryGirl.create(:user, :user_status) 
    visit new_user_session_path

    fill_in "user_email", :with => @user.email
    fill_in "user_password", :with => "qwerty"
    click_button "commitSignIn" #OK sign in
  end

  def login_manager
    @user = FactoryGirl.create(:user, :manager_status) 
    visit new_user_session_path

    fill_in "user_email", :with => @user.email
    fill_in "user_password", :with => "qwerty"
    click_button "commitSignIn" #OK sign in
  end

  def login_admin
    @user = FactoryGirl.create(:user, :admin_status) 
    visit new_user_session_path

    fill_in "user_email", :with => @user.email
    fill_in "user_password", :with => "qwerty"
    click_button "commitSignIn" #OK sign in
  end    
end

但这段代码并不干燥。我需要减少它。我的解决方案：

module Helpers
  after(:each) do
    visit new_user_session_path
    fill_in "user_email", :with => @user.email
    fill_in "user_password", :with => "qwerty"
    click_button "commitSignIn" #OK sign in
  end 

  def login_user
    @user = FactoryGirl.create(:user, :user_status) 
  end

  def login_manager
    @user = FactoryGirl.create(:user, :manager_status) 
  end

  def login_admin
    @user = FactoryGirl.create(:user, :admin_status) 
  end    
end

但我的解决方案没有奏效。控制台显示如下：

kalinin@kalinin ~/rails/phs $ rspec spec/helpers/session_helper_spec.rb
/home/kalinin/rails/phs/spec/helpers/application_helper_spec.rb:2:in
在'for Helpers：Module之后
<module:Helpers>': undefined method （NoMethodError）来自/home/kalinin/rails/phs/spec/helpers/application_helper_spec.rb:1:in `'

after :each是RSpec允许规范示例的东西，而不是任意方法（因此也不适用于辅助方法）。（Rails控制器与around_action具有类似的功能，但它也仅限于控制器中的操作方法。）

怎么样

module Helpers
  def login_user(role=:user)
    @user = FactoryGirl.create(:user, :"#{role}_status") 
    visit new_user_session_path
    fill_in "user_email", :with => @user.email
    fill_in "user_password", :with => "qwerty"
    click_button "commitSignIn" #OK sign in
  end

  def login_manager
    login_user(:manager)
  end

  def login_admin
    login_user(:admin)
  end
end

（未经测试，可能需要一些摆弄。）

如何减少（缩短）帮助程序的代码？
