How to create a ajax callback function in rails

Question

I'm new to Rails and ajaxification on Rails: I'm facing a problem in writing an ajax callback function. For example, if i am writing a callback function for a delete method and write a callback code for ajax in applicaton.js, it works fine when i have written format.js to this method as

format.js { render :nothing => true }

But what i want is both: this format.js works and also the callback function should work. How to do this?

Answer 1

Can you simply try

format.js { render :json => {} }

instead of

format.js { render :nothing => true }

so that your callback function will be called.
