JSON with Ruby on Rails
Ruby on Rails provides built-in support for JSON, allowing easy rendering of JSON responses using the render method in controllers. This means you can quickly return JSON data from your Rails application without any additional configuration. It simplifies the process of interacting with JSON data within Rails applications, making development more efficient.
Below is the program to parse JSON:
class UsersController < ApplicationController
def index
@users = User.all
render json: @users
end
end
We can also parse JSON data from request bodies using the params method. For example, to handle a JSON payload in a POST request:
class UsersController < ApplicationController
def create
@user = User.new(name: params[:name], age: params[:age], city: params[:city])
if @user.save
render json: @user, status: :created
else
render json: @user.errors, status: :unprocessable_entity
end
end
end
