我有以下助手方法(應用程序/傭工/ application_helper.rb):問題與導軌的輔助方法
module ApplicationHelper
#Return a title on a per-page basis
def title
base_title = "Ruby on Rails Tutorial Sample App"
if @title.nil?
base_title
else
"#{base_title} | #{@title}"
end
end
end
和這裏的僱員再培訓局(應用程序/視圖/佈局/ application.html.erb):
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
</body>
</html>
我跑了一個rspec測試,看看這個輔助方法是否工作,看起來它不能找到標題。
這裏的錯誤消息:
Failures:
1) PagesController GET 'home' should be successful
Failure/Error: get 'home'
ActionView::Template::Error:
undefined local variable or method `title' for #<#<Class:0x991ecb4>:0x991315c>
# ./app/views/layouts/application.html.erb:4:in `_app_views_layouts_application_html_erb__248109341_80250010__979063050'
# ./spec/controllers/pages_controller_spec.rb:8:in `block (3 levels) in <top (required)>'
2) PagesController GET 'home' should have the right title
Failure/Error: get 'home'
ActionView::Template::Error:
undefined local variable or method `title' for #<#<Class:0x991ecb4>:0x9d7d094>
# ./app/views/layouts/application.html.erb:4:in `_app_views_layouts_application_html_erb__248109341_82566280__979063050'
# ./spec/controllers/pages_controller_spec.rb:13:in `block (3 levels) in <top (required)>'
誰能告訴我我做錯了什麼?
UPDATE:
我包括通過執行以下操作助手:
describe PagesController do
include ApplicationHelper
render_views
describe "GET 'home'" do
it "should be successful" do
get 'home'
response.should be_success
end
it "should have the right title" do
get 'home'
response.should have_selector("title",
:content => "Ruby on Rails Tutorial Sample App | Home")
end
end
//and some more
但我仍然得到同樣的錯誤
在哪裏我把包括ApplicationHelper在哪裏? – adit
如果我沒有記錯,它需要在描述塊內。 **編輯**剛剛發現這個鏈接http://www.multunus.com/2011/06/rspec-issue-with-include-helper-in-spec/ – Gazler
我編輯了我的問題上面,請檢查 – adit
