Rails 3.1 force .html instead of no extension

问题

One of my clients wants his new Rails application to look more like his traditional web site. He wants to know if I can force urls to have a file extension, preferably .html.

I don't want to hard-code the extension in routes.rb as

match ':controller/:action/:id.html'

(or similar) because the client also wants to have a respond_to-style JSON API which requires the use of .:format.

Can this be done?

回答1:

Just as Mattias Wadman suggested, in config/application.rb add:

AppName::Application.default_url_options = { :format => "html" }

But also change config/routes.rb to:

root :to => 'pages#home', :defaults => { :format => "html" }

Im no Rails routing expert but I tried to force HTML format by changing the default URL options and at least the URL helpers seams to generate .html URLs now, it's a start.

config/application.rb (at the bottom)

AppName::Application.default_url_options = {:format => "html"}
