Question

Suppose I have a model:

class SomeModel(models.Model):     id = models.AutoField(primary_key=True)     a = models.CharField(max_length=10)     b = models.CharField(max_length=7) 

Currently I am using the default Django admin to create/edit objects of this type. How do I remove the field b from the Django admin so that each object cannot be created with a value, and rather will receive a default value of 0000000?

Answer 1

Set editable to False and default to your default value.

http://docs.djangoproject.com/en/stable/ref/models/fields/#editable

b = models.CharField(max_length=7, default='0000000', editable=False) 

Also, your id field is unnecessary. Django will add it automatically.
