Default value for field in Django model

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 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

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

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

You can also use a callable in the default field  such as   b   models CharField max length 7  default foo    And then define the callable   def foo        return  bar
