How to submit form generated by wtforms based on mongoengine model?

Question

MongoDB

Hello, there is a function that builds a form based on the mongoengine model

from flask_wtf import Form
from flask.ext.mongoengine.wtf import model_form
from models.modelfile import DataUser

def add_newuser_form():
    return model_form(DataUser)

there is a get function that gives the page, and what this function gives

def get(self):
        form = add_newuser_form()
        return render_template('admin/admin.html', form =form)

there is a pattern

{% block contentplace %}

                         {{ form.login }}
{% endblock %}

we get an error

File "D:admin_controller.py", line 13, in get
form = add_newuser_form()
File "D:\add_new_user.py", line 9, in add_newuser_form
add_form = model_form(DataUser)
File "C:\Python34\lib\site-packages\flask_mongoengine\wtf\orm.py", line 268, in model_form
field_dict = model_fields(model, only, exclude, field_args, converter)
File "C:\Python34\lib\site-packages\flask_mongoengine\wtf\orm.py", line 225, in model_fields
names = ((k, v.creation_counter) for k, v in model._fields.iteritems())
AttributeError: 'dict' object has no attribute 'iteritems'

why? and how to fix it?

As user @crazyzubr wrote "Edits on the third python, as I see it, have already been made . Only the version has not yet been released. In this case, you can install directly from the
