Create Django App and Data Model

Creating Django App

To manage a project, django divide the project into several small django apps. Django app is a group of related functionality used to complete or maintain one aspect of a site.

The following command will create django app called myapp

$ python manage.py startapp myapp

To make django load the app, we need to add app name in django setting:

$ nano mysite/settings.py

    # project app

Creating Data Model

We often need to store our data into database. In django, we need to define our data model first, then make django to propagate data model creation/changes to database schema by using django commands. In this example, we will create data model inside of django app that we created before.

  1. Create data model
    $ nano myapp/models.py
    # -*- coding: utf-8 -*-
    from __future__ import unicode_literals
    from django.db import models
    class MyModel(models.Model):
        foo = models.IntegerField(default=0)
        bar = models.TextField(blank=True, null=True)
        class Meta:
            db_table = 'my_model_tbl'
  2. Make django migration
    $ python manage.py makemigrations myapp
  3. Apply changes to database schema
    $ python manage.py migrate myapp

    Thanks for the type. I can see how dividing a single application into smaller applications can be really helpful!
