Я использую модель webapp2, ndb.
Я пытался использовать формы модели django с моделью ndb. Ниже приведены соответствующие части моей установки:
app.yaml:
libraries:
- name: webapp2
version: "2.5.1"
- name: jinja2
version: latest
- name: markupsafe
version: latest
- name: django
version: 1.3
Models.py:
class SubTask(ndb.Model):
task = ndb.StructuredProperty(TaskList)
description = ndb.TextProperty()
start_time = ndb.DateTimeProperty()
end_time = ndb.DateTimeProperty()
Forms.py:
from django.forms import ModelForm
from models import TaskList, TaskCategory, SubTask
class SubTaskForm(ModelForm):
class Meta:
model = SubTask
Обработчик:
class CreateSubTask(BaseHandler):
def get(self):
self.render_template('index.html', {'form':SubTaskForm})
app = webapp2.WSGIApplication([('/', IndexPage),
('/subtask', CreateSubTask), ],
debug=True)
Ошибка, которую я получаю: AttributeError: объект типа «SubTask» не имеет атрибута «_meta»
Мой вопрос: есть ли способ использовать формы модели django с ndb, или если я ошибаюсь, что это? Если не django modelforms, модель ndb нормально работает с WTForms?
