Below is an index controller action that maps to a Post model in a Rails application. How would you modify it so that it can respond with a list of posts in either HTML or JSON form, depending on the incoming HTTP request?
class PostsController < ApplicationController
def index
@posts = Post.all
end
end# Your answer goes here...Let's say the Posts in the previous question are available at http://localhost:3000/posts. In a front-end application, how could you do the following using AJAX?
1. Retrieve all the posts in JSON form
2. If Step 1 is successful, print the resulting JSON to the console
3. If Step 1 is unsuccessful, print an error message to the console
// Your answer goes here...Using the same front-end application and Rails API from the previous question, how would you use AJAX to create a Post through the API? You can assume the following...
- The API is RESTful
- The PostsController contains a strong params method that is used when creating an instance of the Post model
- Each Post has title and body attributes, both of which are strings
If the Post creation is successful, the new Post should be printed to the browser console. Otherwise, an error message should be printed to the console.
