no-null-string-field
Avoid using null on string-based fields such as CharField and TextField. If a string-based field has null=True, that means it has two possible values for “no data”: NULL, and the empty string. In most cases, it’s redundant to have two possible values for “no data;” the Django convention is to use the empty string, not NULL.

string-field-must-set-null-true
If a text field declares unique=True and blank=True, null=True must also be set to avoid unique constraint violations when saving multiple objects with blank values.
nontext-field-must-set-null-true
nontext-field-must-set-null-true
null=True should be set if blank=True is set on non-text fields.
