BooleanField - Django Models

Last Updated : 12 Jul, 2025

BooleanField is a true/false field. It is like a bool field in C/C++. The default form widget for this field is CheckboxInput, or NullBooleanSelect if null=True. The default value of BooleanField is None when Field.default isn’t defined. One can define the default value as true or false by setting the default attribute to true/false simultaneously.

Syntax:

field_name = models.BooleanField(**options)

Django Model BooleanField Explanation

Illustration of BooleanField using an Example. Consider a project named geeksforgeeks having an app named geeks.

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

How to Create a Basic Project using MVT in Django?
How to Create an App in Django ?

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

Add the geeks app to INSTALLED_APPS

Now when we run makemigrations command from the terminal,

Python manage.py makemigrations

A new folder named migrations would be created in geeks directory with a file named 0001_initial.py

Now run,

Python manage.py migrate

Thus, an geeks_field BooleanField is created when you run migrations on the project. It is a field to store boolean value - True/False.

How to use BooleanField ?

BooleanField is used for checking the particular condition, for example, to check if Email of a user is verified or not. One can use BooleanField to mark it True or False. We can also set it to False by using default=True.

Now let's check it in admin server. We have created an instance of GeeksModel.

Field Options

Field Options are the arguments given to each field for applying some constraint or imparting a particular characteristic to a particular Field. For example, adding an argument null = True to BooleanField will enable it to store empty values for that table in a relational database.
Here are the field options and attributes that a BooleanField 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.
db_column	The name of the database column to use for this field. If this isn’t given, Django will use the field’s name.
db_index	If True, a database index will be created for this field.
db_tablespace	The name of the database tablespace to use for this field’s index, if this field is indexed. The default is the project’s DEFAULT_INDEX_TABLESPACE setting, if set, or the db_tablespace of the model, if any. If the backend doesn’t support tablespaces for indexes, this option is ignored.
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.
editable	If False, the field will not be displayed in the admin or any other ModelForm. They are also skipped during model validation. Default is True.
error_messages	The error_messages argument lets you override the default messages that the field will raise. Pass in a dictionary with keys matching the error messages you want to override.
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.
verbose_name	A human-readable name for the field. If the verbose name isn’t given, Django will automatically create it using the field’s attribute name, converting underscores to spaces.
validators	A list of validators to run for this field. See the validators documentation for more information.
Unique	If True, this field must be unique throughout the table.
