<p>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?</p>

<p>Thanks.</p>

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