How can Django set the binary attribute to the varchar field in models?

Question

Django

Actually, the task is to make such a field in the DBMS so that the index on it is built according to the principle of a text field (i.e. "a" in sorting before "aa" ), but inside it could also store binary data data (i.e. distinguished case in comparisons etc). If you do it directly in MySQL, then to get the required one, it is enough to indicate the sign binary for the varchar field. And how to achieve the same models.pythrough Django ?
The Django models binary field doesn't seem to do quite right.

Answer 1

Alternatively, you can create a class inherited from the models.Field
type and override the method in it:

def db_type(self, connection):
        return 'VARBINARY(%s)' % self.max_length

Then in the model you define a field of this class
