Render JSON instead of HTML as default?
提问by trnc
I try to tell rails 3.2 that it should render JSON by default, and kick HTML completely like this:
我试图告诉 rails 3.2 它应该默认呈现 JSON,并像这样完全踢 HTML:
respond_to :json
def index
@clients = Client.all
respond_with @clients
end
With this syntax, I have to add .jsonto the URL. How can I achieve it?
使用此语法,我必须添加.json到 URL。我怎样才能实现它?

You can modify your routes.rbfiles to specify the default format
您可以修改routes.rb文件以指定默认格式
routes.rb
路由文件
resources :clients, defaults: {format: :json}
This will modify the default response format for your entire clients_controller
这将修改您的整个默认响应格式 clients_controller

If you don't need RESTful responding in your index action then simply render your xml response directly:
如果您在索引操作中不需要 RESTful 响应,那么只需直接呈现您的 xml 响应:
def index
render json: Client.all
end

This pattern works well if you want to use the same controller actions for both. Make a web version as usual, using :html as the default format. Then, tuck the api under a path and set :json as the default there.
如果您想对两者使用相同的控制器操作,则此模式非常有效。像往常一样制作网络版本,使用 :html 作为默认格式。然后,将 api 放在路径下并将 :json 设置为默认值。
Rails.application.routes.draw do
resources :products
scope "/api", defaults: {format: :json} do
resources :products
end
end
