There is no DoubleField in Django but FloatField [FloatField description in Django's Model field reference] creates a double datatype in mysql.

Django's TextField creates a LONGTEXT type in mysql. There is no easy way to change TextField behaviour to create e.g. MEDIUMTEXT type in mysql. But one can create a custom model field to achieve that: Writing custom model fields
