Is there a quick way to use AJAX in Rails?

By using the remote:true attribute on a form and responding from the controller with :js, Rails is instructed to run a specific javascript file.

For instance, when deleting a user, you would have the User controller with the Destroy action. Then, you would create a file called views/users/destroy.js.erb containing something like this:

$("ul#users").html("<%= j render partial: 'user_list' %>");

My question is... Is there a way to streamline this process and avoid having multiple small files scattered throughout the application? If all I need is to render a partial with some variables, is there a quicker method such as:

respond_with render :js, with: 'partial_foo', on: '#selector .bar'

Is there a shortcut available for this?

Answer №1

If you're looking for a handy trick, why not try using json and managing the response with your unobtrusive JS?

#view
<%= form_for @variable, remote: :true, method: :json %>

#controller
respond_to :json, :html

def action
    respond_with @variable
end

Utilizing JSON allows for compact serialized data objects, removing the need to deal with files and enabling flexibility in data handling:

#app/assets/javascripts/application.js
$(element).on("ajax:success", function(data) {
    message = JSON.stringify(data);
    alert(message.attribute);
});

If you find this concept appealing, I can propose additional strategies for managing the partial
