Как в Django views обработать несколько formset?

Делаю сайт конструктор, который состовляется из блоков. У каждого блока есть своя сущность, котороые могут иметь еще дополнительный связанные сущности. Например: есть сущность странца, у неё полиморфная связь с разными типа блоков ( галлерея, услуги ..). У Галлереи может быть несколько картинок, у блока услуг может быть несколько услуг.

Делаю страницу редактирования контента в виде большой формы состоящей из "джанговских" форм и формсетов. Проблема в том, что у форм и формсетов, которые я формирую во viewa.py аттрибуты input'ов не уникальный, поэтому когда в request.POST приходят поля со списками значений.

request.POST = <QueryDict: {'csrfmiddlewaretoken': ['QqdKa3H3J2cgCs1tH7iRWuLtmzSjHeSOZI3gXes2Dc6zBfjn0HzBU20mBmuwjdkz', 'QqdKa3H3J2cgCs1tH7iRWuLtmzSjHeSOZI3gXes2Dc6zBfjn0HzBU20mBmuwjdkz'], 'title': ['Контакты123', 'Контакты123', 'Мои работы', 'Контакты'], 'string_1': ['Щербина'], 'string_2': ['Владимир'], 'string_3': ['123'], 'subtitle': ['фотографирую сам'], 'background': [''], 'form-TOTAL_FORMS': ['2', '4'], 'form-INITIAL_FORMS': ['1', '3'], 'form-MIN_NUM_FORMS': ['0', '0'], 'form-MAX_NUM_FORMS': ['1000', '1000'], 'form-0-picture': ['', ''], 'form-0-title': ['Услуга номер 123'], 'form-0-description': ['Описание', 'Описание'], 'form-0-id': ['34', '34'], 'form-1-picture': ['', ''], 'form-1-title': [''], 'form-1-description': ['', 'Описание'], 'form-1-id': ['', '35'], 'form-2-picture': [''], 'form-2-description': ['Описание'], 'form-2-id': ['36'], 'form-3-picture': [''], 'form-3-description': [''], 'form-3-id': [''], 'picture': [''], 'form-0-type': ['4'], 'form-0-value': ['89882530660'], 'form-0-show_in_header': ['on'], 'form-1-type': ['7'], 'form-1-value': ['[email protected]'], 'form-1-show_in_header': ['on'], 'form-2-type': ['4'], 'form-2-value': ['89882530660'], 'form-2-show_in_header': ['on'], 'form-3-type': ['7'], 'form-3-value': ['[email protected]'], 'form-3-show_in_header': ['on'], 'form-4-type': [''], 'form-4-value': [''], 'form-4-show_in_header': ['0']}>

как в formset изменить префикс для аттрибута 'name'? Например вместо 'form-0-title' было 'gallery-0-title'
