Initialization

Simply run the following commands in your terminal.

$ bundle install
$ rake db:migrate

After running the commands above, run rails s to make the api up and running.

Testing

First of all, create some data by running the code below.

$ rake db:seed

Get posts

Now you can use Postman to test if the api is working properly. Make a get request to http://localhost:3000/api/v1/posts and you will get the json formatted data like the code below.

{
    "status": "SUCCESS",
    "message": "loaded posts",
    "data": [
        {
            "id": 3,
            "title": "title3",
            "created_at": "2018-12-20T00:47:13.266Z",
            "updated_at": "2018-12-20T00:47:13.266Z"
        },
        {
            "id": 2,
            "title": "title2",
            "created_at": "2018-12-20T00:47:09.688Z",
            "updated_at": "2018-12-20T00:47:09.688Z"
        },
        {
            "id": 1,
            "title": "title1",
            "created_at": "2018-12-20T00:47:02.036Z",
            "updated_at": "2018-12-20T00:47:02.036Z"
        }
    ]
}

    }
}

        "updated_at": "2018-12-20T02:15:30.945Z"
    }
}
