如何在Rails 3的功能测试中使用polymorphic_path [英] How to use polymorphic_path in a functional test in Rails 3

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'
