Hello I have model like

class mymodel(models.Model):

    a = models.CharField(blank=True, null=True, max_length=255)

    b = models.CharField(blank=True, null=True, max_length=255)

    c = models.CharField(blank=False, null=False, max_length=255)

Since I'm using the django admin as a back-end controller of the data stored in my model I want to make either one of them to not be null

for example the user must either fill a or either fill b or both to be filled, but if both are empty must throw an error

You can add custom validation like this

class mymodel(models.Model):

    a = models.CharField(blank=True, null=True, max_length=255)

    b = models.CharField(blank=True, null=True, max_length=255)

    c = models.CharField(blank=False, null=False, max_length=255)



    def clean(self):

        if not (self.a and self.b):

            raise ValidationError(....)
