问题描述
我正在尝试在Rails 3的功能测试中使用polymorphic_path
.
I'm trying to use polymorphic_path
in a functional test in Rails 3.
起初我会得到
NoMethodError: undefined method `polymorphic_path' for #<ArticlesControllerTest:0x492f17c>
然后我添加了
include Rails.application.routes.url_helpers
undefined method error
已停止,但现在常规路径(例如article_path(article)
)已停止工作:
The undefined method error
stopped, but now regular paths, like article_path(article)
for example stopped working:
NameError: undefined local variable or method `default_url_options' for #<ArticlesControllerTest:0x33ccbe0>
.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.0.9/lib/action_dispatch/testing/assertions/routing.rb:175:in `method_missing'
.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.0.9/lib/action_dispatch/routing/url_for.rb:102:in `url_options'
.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.0.9/lib/action_dispatch/routing/url_for.rb:131:in `url_for'
.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.0.9/lib/action_dispatch/routing/route_set.rb:195:in `article_path'
我曾经能够通过包含
include ActionController::UrlWriter
如何在Rails 3中使用它?
How can I get this to work in Rails 3?
推荐答案
我需要包括:
include ActionDispatch::Routing::UrlFor
include Rails.application.routes.url_helpers
并设置:
default_url_options[:host] = 'www.example.com'
