Merging two JSON

Merging two JSON.rb

#How I retrieve my JSON :

class CoursesController < ApplicationController
require 'net/https'
require "uri"
require "json"

  # List with the courses'information from several sources
  def list
    # Option 2
    require "open-uri"
    canvas_api_courses_json = open("https://xxxxx/").read

    database_courses = Course.all
    database_courses_json = database_courses.to_json
  end
end

#First JSON Result

[
  {
   "course_code":"Basic 101 - 0913",
   "name":"Basic 101",
   "start_at":"2013-09-16T00:00:00+02:00",
   "end_at":"2013-10-13T23:55:00+02:00",
   "workflow_state":"available"
  },
  {"course_code":"Medium 201 - 0913",
   "name":"Medium 201",
   "start_at":"2013-08-06T16:55:25+02:00",
   "end_at":null,
   "workflow_state":"available"
  }
]

# Secon JSON Result

[
  {
   "id":1,
   "course_id":"Basic 101",
   "name":"Basic Level",
   "description":"blablabla",
   "discipline_id":"1",
   "duration":"28",
   "created_at":null,
   "updated_at":null
  },
  {
   "id":2,
   "course_id":"Medium 201",
   "name":"Medium Level",
   "description":"blablabla",
   "discipline_id":"1",
   "duration":"28",
   "created_at":null,
   "updated_at":null
  }
]


## Here is the solution : 

class CoursesController < ApplicationController
require 'net/https'
require "uri"
require "json"

  # List with the courses'information from several sources
  def list
    # Option final
    require "open-uri"
    canvas_api_courses_json = open("https://xxxxxxxx").read

    database_courses = Course.all
    database_courses_json = database_courses.to_json

    canvas_api_courses_hash = JSON.parse(canvas_api_courses_json)
    database_courses_hash = JSON.parse(database_courses_json)
    courses_list = []
    canvas_api_courses_hash.each do |json_key_1|
      database_courses_hash.each do |json_key_2|
        if json_key_2['course_id'] == json_key_1['name']
        courses_list.push(json_key_1.merge(json_key_2))
        end
      end
    end
    @courses_lis_export = courses_list.to_json
  end
end
