Default value for field in Django model

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

From stackoverflow

• Set editable to False and default to your default value.

  http://docs.djangoproject.com/en/dev/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.

  Yuval A : yeah I know about the id field. Thanks for the help!

• You can set the default like this:

  b = models.CharField(max_length=7,default="foobar")
  

  and then you can hide the field with your model's Admin class like this:

  class SomeModelAdmin(admin.ModelAdmin):
      exclude = ("b")
