How to store value in NullBooleanField from Django form

I am trying to insert data into a NullBooleanField() from a Django form, however, only 'True' is ever added.

I have printed the cleaned data from 3 different fields from the form and it looks as follows:

True
False
None

(Which is what I would expect it to look like - as I selected 3 different options)

This is what the form fields look like:

MY_CHOICES = [(True, 'Yes'), (False, 'No'), (None, 'N/A')]

field_1 = forms.ChoiceField(
    required=True,
    choices=MY_CHOICES,
    widget=forms.RadioSelect(renderer=HorizontalRadioRenderer),
    label="Field 1"
)

And this is what the fields in the model looks like:

field_1 = models.NullBooleanField()

I don't understand why the data always inserts as 'True' when I check in Django admin.

In Django admin, the choices are as follows: "Yes, No, Unknown"

So I have tried changing the form choices to read as follows:

MY_CHOICES = [('Yes', 'Yes'), ('No', 'No'), ('Unknown', 'N/A')]

But yet again, this does not work.

Can anyone suggest what might be the issue here?

EDIT -- Showing how this is saved to model

new_entry = ModelName(
    field_1=form.cleaned_data['field_1'],
    field_2=form.cleaned_data['field_2'],
    field_3=form.cleaned_data['field_3'],
)
new_entry.save()

Solution

Here is how to solve the issue.

forms.NullBooleanField(
    widget=forms.RadioSelect(renderer=HorizontalRadioRendererSpace,
        choices=CHOICES),
    label='...',
    required=False
)

NullBooleanField needs to be used when dealing with NullBooleanField in the model
