How to generate links with trailing slash in Rails

问题:

I'm porting the existing website from PHP to Ruby on Rails 3 and I have to keep the urls unchanged.

I have the route:

get 'companies/' => 'companies#index', :as => :companies

In a view file I have:

link_to 'Companies', companies_path

and this generates the url "http://website.com/companies" instead of "http://website.com/companies/".

I want the slash at the end of the url. Is it possible?

回答1:

You can add this to your application.rb:

config.action_controller.default_url_options = { :trailing_slash => true }

This way all routes will be generated with a trailing slash automatically, with no need to modify each link in your project.

Simply do as follows:

link_to 'Companies', companies_path(:trailing_slash => true)

Documentation here.

I couldn't find any references, but adding trainling_slash: true to the route definition also works (and avoids repeating oneself).

get 'companies/' => 'companies#index', :as => :companies, :trailing_slash => true

This was tested with Rails 3.2.13:

rails c
1.9.3p327 :005 > app.companies_path
=> "http://www.example.com/companies/

For rails 3.2:

Rails.application.routes.default_url_options[:trailing_slash]= true
