In this article, we will create a basic model of an app. Say, we have a project geeksforgeeks in which we will create a new app in order to simplify and make independent model units.

To create an app run command through terminal :

python startapp geeks

and add geeks to INSTALLED_APPS list in Now directory structure of the app will be,


Now go to in geeks app, Here we will create our first model. To create a model you need to first import the Model from django.db.models library.

Now will look like,

# importing Model from django
from django.db.models import Model

According to Django documentation, A model is the single, definitive source of information about your data. It contains the essential fields and behaviours of the data you’re storing. Generally, each model maps to a single database table.

Django provides a number of predefined fields and methods to create a Model. To create a model you need to specify a model name first.

Enter the following code into

from django.db import models
from django.db.models import Model
# Created an empty model 
class GeeksModel(Model):

The similar syntax would always be used to create a model.
After making any change in any of app’s models file you need to run following command from the terminal

 Python makemigrations

After this command run following command to finally implement database changes accordingly

 Python migrate 

After you run makemigrations and migrate a new table would have been created in database. You can check it from geeks -> makemigrations ->

# Generated by Django 2.2.5 on 2019-09-25 06:00
from django.db import migrations, models
class Migration(migrations.Migration):
    initial = True
    dependencies = []
    operations = [
            name ='GeeksModel',
            fields =[
                ('id', models.AutoField(auto_created = True,
                  primary_key = True, serialize = False,
                  verbose_name ='ID')),], ),

Let’s understand clearly what Makemigrations and Migrate do.

Makemigrations –

makemigrations basically generates the SQL commands for preinstalled apps (which can be viewed in installed apps in and your newly created apps’ model which you add in installed apps. It does not execute those commands in your database file. So tables are not created after makemigrations.

After applying makemigrations you can see those SQL commands with sqlmigrate which shows all the SQL commands which have been generated by makemigrations. To check more about makemigrations visit – Django App Model – Python makemigrations command

Migrate –

migrate executes those SQL commands in the database file. So after executing migrate all the tables of your installed apps are created in your database file.

You can confirm this by installing sqlite browser and opening db.sqlite3 you can see all the tables appears in the database file after executing migrate command. To check more about makemigrations visit Django migrate command | Python
