当我加载时script/console,有时我想要使用控制器的输出或视图助手方法.
有办法:
模拟请求？
在所述请求上从控制器实例调用方法？
通过所述控制器实例或其他方式测试助手方法？

要调用帮助程序,请使用以下helper对象:
$ ./script/console
>> helper.number_to_currency('123.45')
=> "R$ 123,45"
如果您想使用默认情况下未包含的帮助程序(例如,因为您已helper :all从中删除ApplicationController),只需包含帮助程序即可.
>> include BogusHelper >> helper.bogus => "bogus output"
至于处理控制器,我引用尼克的回答:
> app.get '/posts/1' > response = app.response # you now have a rails response object much like the integration tests > response.body # get you the HTML > response.cookies # hash of the cookies # etc, etc
我观察到我不能执行多个`app.get`(线程错误随之而来).有没有办法可以刷新系统并执行更多的获取？ (4认同)
注意在Rails 3.2中这不起作用.我需要从控制台调用`url_for`.为此,我做了'app.url_for(...)` (2认同)

从脚本/控制台调用控制器操作并查看/操作响应对象的简单方法是:
> app.get '/posts/1' > response = app.response # You now have a Ruby on Rails response object much like the integration tests > response.body # Get you the HTML > response.cookies # Hash of the cookies # etc., etc.
app对象是ActionController :: Integration :: Session的一个实例
这适用于我使用Rails 2.1和2.3,我没有尝试早期版本.

如果您需要从控制台进行测试(在Rails 3.1和4.1上测试):
呼叫控制器动作:
app.get '/'
app.response
app.response.headers # => { "Content-Type"=>"text/html", ... }
app.response.body # => "\n\n\n\n..."
ApplicationController方法:
foo = ActionController::Base::ApplicationController.new foo.public_methods(true||false).sort foo.some_method
路线助手:
app.myresource_path # => "/myresource" app.myresource_url # => "http://www.example.com/myresource"
查看助手:
foo = ActionView::Base.new foo.javascript_include_tag 'myscript' #=> "" helper.link_to "foo", "bar" #=> "foo" ActionController::Base.helpers.image_tag('logo.png') #=> ""
渲染:
views = Rails::Application::Configuration.new(Rails.root).paths["app/views"]
views_helper = ActionView::Base.new views
views_helper.render 'myview/mytemplate'
views_helper.render file: 'myview/_mypartial', locals: {my_var: "display:block;"}
views_helper.assets_prefix #=> '/assets'
ActiveSupport方法:
require 'active_support/all'

=> 2013-08-31 10:07:26 -0300
a = {'a'=>123}
a.symbolize_keys
=> {:a=>123}
Lib模块:
> require 'my_utils' => true > include MyUtils => Object > MyUtils.say "hi" evaluate: hi => true
这是通过控制台执行此操作的一种方法:
