In a rails controller action with the following code:
respond_to do |format| format.json{ render :json=> {:status => 200, :response=>@some_resource} } format.html { redirect_to(some_resource_path)} end How can I log the format the controller will resolve i.e. 'HTML' or 'json'? format is of type Collector. Is there a way of getting a string denoting the format?

By default, if you use the :text option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option.
Rails Guides describes partials this way: Partial templates - usually just called "partials" - are another device for breaking the rendering process into more manageable chunks. With a partial, you can move the code for rendering a particular piece of a response to its own file.
There is an important difference between render and redirect_to: render will tell Rails what view it should use (with the same parameters you may have already sent) but redirect_to sends a new request to the browser.
render :json essentially calls to_json and returns the result to the browser with the correct headers. This is useful for AJAX calls in JavaScript where you want to return JavaScript objects to use. Additionally, you can use the callback option to specify the name of the callback you would like to call via JSONP.
The method to access the format is:
controller.request.format If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
