Inspectdb generates CharFields with null=true for mysql tables that have attributes which allow Null values. This is not Django convention:
If True, Django will store empty values as NULL in the database. Default is False.
Note that empty string values will always get stored as empty strings, not as NULL -- so use null=True for non-string fields such as integers, booleans and dates.
Avoid using null on string-based fields such as CharField and TextField unless you have an excellent reason. 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;" Django convention is to use the empty string, not NULL."
