如何减少（缩短）助手代码？

Question

请帮忙解决问题

用户工厂绑定助手：

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

不过这段代码并不干货。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

但我的解决方案无效。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
<module:Helpers>': undefined methodafter' for Helpers:Module (NoMethodError) from /home/kalinin/rails/phs/spec/helpers/application_helper_spec.rb:1:in `'

Answer 1

after :each 是 RSpec 允许 规范示例 ，而不是任意方法（因此也不适用于辅助方法）。（Rails 控制器具有与 around_action 类似的功能，但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，因此可能需要一些调整。）
