Overriding a MIME type in Rails

Question

I want to override the JSON MIME type ("application/json") in Rails to ("text/x-json"). I tried to register the MIME type again in mime_types.rb but that didn't work. Any suggestions?

Thanks.

Answer 1

This should work (in an initializer, plugin, or some similar place):

Mime.send(:remove_const, :JSON)
Mime::Type.register "text/x-json", :json

Answer 2

Try:

render :json => var_containing_my_json, :content_type => 'text/x-json'
