How to make Required: boolean field in model Django

Question

I have a model with a field called in is_student and is_teacher Student and Teacher forms

is_teacher = models.BooleanField('teacher status', default=False)
is_student = models.BooleanField('student status', default=False)

I want to make sure this field is:

• Always Checked by the user True *Required

Currently: is_teacher in TeacherApplications Model

• When unchecked - it saved 0 to the form and continues. (Not good)

• When checked gives me this error:

ValueError at /register/teacher invalid literal for int() with base 10: ''

Currently: is_student in StudentProfile Model

• When checked gives this error

ValidationError at /register/ ["'on' value must be either True or False."]

• When unchecked it saved 0 to the form and continues. (Again, not good)

UPDATED CODE

---

Above errors are gone: New error each time I try to submit form after checking is_teacher/is_student

IntegrityError at /register/ NOT NULL constraint failed: accounts_studentprofile.is_student

Answer 1

You can add this fields to StudentResistrationForm and TeacherRegistrationForm and add custom validation for it in clean_fieldname method to make it required:

StudentResistrationForm(ModelForm):
    class Meta:
        model = StudentRegistration
        fields = (
            'instrument',
            'skill',
            'experience_in_years',
            'is_student',
        )

    def clean_is_student(self):
        is_student = self.cleaned_data.get('is_student')
        if not is_student:
            raise forms.ValidationError('This field is required')
        return is_student  

Also in view instead of getting raw data from request.POST you can use forms to create student and teacher objects:

new_user = User.objects.create_user(username=username, email=email, password=password)
teacher = form.save(commit=False)
teacher.user = new_user
teacher.save()
