Using IPAddressField in Django to Define IP Address Fields

In Django, the IPAddressField class is used to define IP address fields in models. This field is used to store IP addresses in the database. In this article, we will explore how to use IPAddressField in Django to define IP address fields.

What is IPAddressField?

IPAddressField is a field in Django that is used to store IP addresses. It is a subclass of Field and is used to store IP addresses in the database. The IPAddressField class is defined in the django.db.models.fields module.

Defining IPAddressField in a Model

To define an IPAddressField in a model, you can use the following syntax:

from django.db import models

class MyModel(models.Model):
    ip_address = models.IPAddressField()

In this example, we define a model called MyModel with an IPAddressField called ip_address.

IPAddressField Options

The IPAddressField class has several options that can be used to customize its behavior. These options include:

• protocol: This option specifies the protocol to use for the IP address. It can be either 'both' (the default), 'ipv4', or 'ipv6'.
• unpack_ipv4: This option specifies whether to unpack IPv4 addresses. It is only used when protocol is 'both' or 'ipv4'. The default is False.

Here is an example of how to use these options:

from django.db import models

class MyModel(models.Model):
    ip_address = models.IPAddressField(protocol='ipv4', unpack_ipv4=True)

IPAddressField Validation

The IPAddressField class has built-in validation to ensure that the IP address is valid. It checks that the IP address is in the correct format and that it is a valid IP address.

IPAddressField in Forms

When using IPAddressField in a form, Django provides a built-in form field called IPAddressField. This form field is used to validate the IP address and ensure that it is in the correct format.

from django import forms
from .models import MyModel

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ('ip_address',)

IPAddressField in Templates

When displaying an IPAddressField in a template, Django provides a built-in template filter called ipaddr. This filter is used to format the IP address in a human-readable format.

{% load ipaddr %}

{{ my_object.ip_address|ipaddr }}
