Python Methods and Functions

Syntax :

 field_name = models.PositiveSmallIntegerField ( ** options ) 

Django Model PositiveSmallIntegerField Explanation

Illustration of PositiveSmallIntegerField using example. Consider a project named pythonengineering that has an application named geeks .

Refer to the following articles to check how to create a project and an app in Django.

Enter the following code into the models.py file of the geeks application.

Add the geek app to INSTALLED_APPS

from django.db import models

from django.db.models import Model

# Create your models here.


class GeeksModel (Model):

geeks_field = models.PositiveSmallIntegerField ()

# Application definition



  ` django .contrib.admin` ,

`django.contrib.auth` ,

`django.contrib.contenttypes` ,

`django.contrib.sessions` ,

`django.contrib. messages` ,

`django. contrib.staticfiles` ,

` geeks` ,


Now when we run the makemigrations command from the terminal,

 Python manage. py makemigrations 

In the geeks a new folder named migrations will be created with a file named 0001_initial.py

# Generated by Django 2.2 .5 at 2019-09-25 06:00


from django.db import migrations, models


class Migration (migrations. Migration):


initial = True


  dependencies = [



operations = [

migrations.CreateModel (

name = `GeeksModel` ,

  fields = [

( `id`

  models.AutoField (

auto_created = True ,

primary_key = True ,

serialize = False

verbose_name = `ID`


( ` geeks_field`

models.PositiveSmallIntegerField ()),




Now run,

 Python manage.py migrate 

So the geeks_field PositiveSmallIntegerField is created when you run migrations in the project. This is a field for storing positive integers.

How to use PositiveSmallIntegerField?

PositiveSmallIntegerField is used to store an integer, represented in Python by an int instance. To learn more about Int, visit

# model import
# from the geek app

from geeks.models import GeeksModel

# create an instance
# int

d = int ( 2189 )

# create an instance
# GeeksModel

geek_object = GeeksModel.objects.create (geeks_field = d)

geek_object.save ()

Now let`s check it out on the admin server. We have created a GeeksModel instance.

Field options

Field parameters — they are arguments given to each field to apply some constraint or to convey a particular characteristic to a particular field. For example, adding the null = True argument to PositiveSmallIntegerField will allow it to store empty values ​​for that table in a relational database. 
Here are the field options and attributes that PositiveSmallIntegerField can use.

Field Options Description
Null If True , Django will store empty values ​​as NULL in the database. Default is False.
Blank If True , the field is allowed to be blank ... Default is False.
Choices An iterable (eg, a list or tuple) of 2-tuples to use as choices for this field.
Default The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created.
help_text Extra “help” text to be displayed with the form widget. It`s useful for documentation even if your field isn`t used on a form.
primary_key If True, this field is the primary key for the model .
Unique If True, this field must be unique throughout the table.
