I've followed the tutorial available at http://railscasts.com/episodes/221-subdomains-in-rails-3.
It allows you to pass a subdomain option to your routes by overriding the url_for method in a helper file. I've helper method looks like this:
module UrlHelper
def with_subdomain(subdomain)
subdomain = (subdomain || "")
subdomain += "." unless subdomain.empty?
[subdomain, request.domain, request.port_string].join
end
def url_for(options = nil)
if options开发者_JS百科.kind_of?(Hash) && options.has_key?(:subdomain)
options[:host] = with_subdomain(options.delete(:subdomain))
end
super
end
end
so:
sites_homepage_url(:subdomain => "cats")
produces the url:
"http://cats.example.com/sites/1/homepage"
This works fine in development. In my cucumber tests, however, using:
sites_homepage_url(:subdomain => "cats")
produces:
"http://www.example.com/sites/1/homepage?subdomain=cats"
which indicates the functionality I added to url_for in the helper isn't working. Anyone got any ideas?
Edit: Formatting and added the code for the UrlHelper.
As the other solutions have not worked, you can try a harder one.
In an initializer file (like config/initializers/url_for_patch.rb), add this:
ActionView::Helpers::UrlHelper.class_eval do
def with_subdomain(subdomain)
subdomain = (subdomain || "")
subdomain += "." unless subdomain.empty?
[subdomain, request.domain, request.port_string].join
end
alias_method_chain :url_for, :subdomain
def url_for_with_subdomain(options = nil)
if options.kind_of?(Hash) && options.has_key?(:subdomain)
options[:host] = with_subdomain(options.delete(:subdomain))
end
url_for_without_subdomain( options )
end
end
You can try add below code in your integration testing
include ActionView::Helpers::UrlHelper
The code in your question is defining a new UrlHelper
module in the top-level namespace. If you're trying to override methods in ActionView::Helpers::UrlHelper
, you'll need to fully qualify the module:
module ActionView
module Helpers
module UrlHelper
def url_for
# override as in your question
end
end
end
end
I'm not sure if Rails will be entirely happy with that in app/helpers, so you might need to put this in lib/action_view/helpers/url_helper.rb
(if you're using autoloading from the lib
folder), or you'll need to explicitly require the file in your config/application.rb
