Create.js.erb, destroy.js.erb: how these files fit into a Rails application

Question

I was unable to find documentation that describes how and how create.js.erbthey destroy.js.erbfit into a Rails 3 application.

What is the logic of these Javascript file types in applications> controllers? How and when are they available?

Answer 1

File extensions are associated with Mime types. Check out my answer here . This was written for Rails 2.2.2, but the same logic is still preserved. Note that the syntax respond_tohas changed in Rails 3.
Also, these files are not in app/controllers, but inapp/views/<controller_name>/

Answer 2

XMLHttpRequest, , javascript.

:

class MyController < ApplicationController

  respond_to :html, :js

  def show
    @my_model = MyModel.find(params[:id])

    respond_with @my_model
  end

end

show html html je js XMLHttpRequest.
