Django models “blob” field

I want to create a table like so -

CREATE TABLE trial_xml (
id int(11) DEFAULT NULL,
pid int(11) DEFAULT NULL,
sid varchar(256) CHARACTER SET utf8 NOT NULL,
data blob,
PRIMARY KEY ( soid ), KEY suid_index ( suid ) ) ENGINE=MyISAM DEFAULT CHARSET=latin1

my question is how do I set "data" field as "blob" in django's models.py ??

I mean what's the syntax?

UPDATE: I dont want to set data field as longtext . I want only blob datafield.

I have been using this simple field for 'mysql' backend, you can modify it for other backends

class BlobField(models.Field):
    description = "Blob"
    def db_type(self):
        return 'blob'

For what it's worth, Django now has a proper BinaryField. It was added on Dec 13, 2012.

The relevant documentation is available here: https://docs.djangoproject.com/en/1.8/ref/models/fields/#binaryfield

Django's ORM has no field for binary large objects. Either use something like a FileField , or search for candidate field classes using a search engine.
