Blog Post Index Example

The URL for your blogging backend that retrieves an index of all posts looks like this:

http://wwwr.cs.unc.edu/emilyblog/posts.json

The responseJSON property of the Ajax.Response object that is sent to the onSuccess handler will contain a JavaScript array. Each entry in the array will be a object that represents each blog post. These entry objects will each contain the following properties:

id

The numeric ID associated with this blog post.

title

The title of the blog post as a string.

body

The body of the blog post as a string.

created_at

The date that the blog post was created as a string.

Other notes:

• When setting up the Ajax.Reqest object to fetch this URL, you need to be sure to set the method property of the Ajax options object to be 'get'. It usually defaults to 'post', but the backend interprets HTTP post requests for this resource as a request to create a new post. See the Creating A New Post Example.
• The date property is a string, but it can be turned into a proper JavaScript Date object by passing it to a Date constructor. You may want to do this if you want to generate a different date format or otherwise work with or manipulate the value that the date represents. See here for documentation about the JavaScript Date objects.
