问题
As ActionController::Base#default_url_options is deprecated, I wonder how to set default url options in rails3. The default url options are not static but dependent of the current request.

回答1:
To set url options for current request use something like this in your controller:
class ApplicationController < ActionController::Base
def url_options
{ :profile => current_profile }.merge(super)
end
end
Now, :profile => current_profile will be automerge to path/url parameters.
Example routing:
scope ":profile" do
resources :comments
end
Just write:
comments_path
and if current_profile has set to_param to 'lucas':
/lucas/comments

I believe the preferred method is to now tell the router to handle this:
Rails.application.routes.default_url_options[:foo]= 'bar'
You can put this line in either routes.rb
or an initializer. Whichever you would prefer. You could even put it in your environment configs if the values change based on your environment.

That apidock.com link is misleading. default_url_options is not deprecated.
http://guides.rubyonrails.org/action_controller_overview.html#default_url_options
回答4:
For Rails 3 specifically, the canonical way to do it is by adding a default_url_options
method to your ApplicationController
.
class ApplicationController < ActionController::Base
def default_url_options
{
:host => "corin.example.com",
:port => "80" # Optional. Set nil to force Rails to omit
# the port if for some reason it's being
# included when you don't want it.
}
end
end
I just had to figure this out myself, so I know it works.
This is adapted from the Rails 3 Guide:
http://guides.rubyonrails.org/v3.2.21/action_controller_overview.html#default_url_options
回答5:
Rails.application.routes.default_url_options[:host]= 'localhost:3000'
In the developemnt.rb / test.rb, can be more concise as following:
Rails.application.configure do
# ... other config ...
routes.default_url_options[:host] = 'localhost:3000'
end
