管理员Django字段排除下拉列表

Question

I have the following model

class Consultation(models.Model):
    id = models.AutoField('Id', primary_key=True)
    date = models.DateTimeField('date')
    services = models.CharField('services', choices=SERVICES, max_length=200, null=True, blank=True)
    weight = models.DecimalField('weight', decimal_places=1, max_digits=10)
    size = models.DecimalField('size', decimal_places=1, max_digits=10)
    imc = models.DecimalField('size', decimal_places=1, max_digits=10)

I have the field "service", in which three options ('a', 'b', 'c') are deployed.

my question is: is it possible that when you create a record of this model (add), selecting for example the option "a" field "service", the 'imc' field is excluded?

I tested with the method "get_form" but does not work when I want to add a record only when already registered.

thanks for the help!

Answer 1

You can do the exclude validations in the clean method of your Consultation class. Check the below link and you can implement a similar validation like the following

if services == 'a':
    self.fields['imc'].required = False
