Creating JavaScript for partial in Rails 3

I am fairly new to using rails and still getting the hang of things. I have a quick question about an AJAX form that I have set up (with :remote => true) which successfully sends data to the server without reloading the page.

My query is regarding the javascript file that should be executed after the form is submitted. My partial is named '_newsomething.html.erb' and I want to trigger a specific javascript file once the data is posted. Do these javascript files need to correspond with actions in the controller to function correctly in rails? Currently, I have a javascript file named 'create.js.erb' which simply contains a javascript alert, but it doesn't seem to be triggering.

For example, do I need to create a partial called '_create.html.erb' along with a corresponding javascript file 'create.js.erb'? Is there a way to specify within the controller where Rails should look for the javascript file?

Thank you in advance!

EDIT: Below is the code snippet from the Controller (very basic and auto-generated)

  def create
@snip = Snip.new(params[:snip])

respond_to do |format|
  if @snip.save
    format.html { redirect_to(@snip, :notice => 'Snip was successfully created.') }
    format.xml  { render :xml => @snip, :status => :created, :location => @snip }
  else
    format.html { render :action => "new" }
    format.xml  { render :xml => @snip.errors, :status => :unprocessable_entity }
  end
end

end

Answer №1

Ensure that your controller action includes the following code:

respond_to do |format|
  format.html { .... }
  format.js

The inclusion of format.js is crucial. When Rails detects that you are making a POST request via AJAX, it will automatically render the _create.js.erb partial.
