基于本教程,我正在尝试创建一个表单来进行一些测量.似乎显示数据的部分正在工作,但是当使用model_form命令生成输入表单时,它会突然出现以下错误:

在转换'description'中输入文件"/myproject/lib/python3.4/site-packages/flask_mongoengine/wtf/orm.py",第49行:field.help_text或'',

AttributeError:'ObjectIdField'对象没有属性'help_text'

错误发生在我的代码的这一行:

form_cls = model_form(Measurement, exclude=('id', 'created_at', 'comments'))

这是我的view.py代码:

from flask import Blueprint, request, redirect, render_template, url_for
from flask.views import MethodView
from flask.ext.mongoengine.wtf import model_form
from pyReefLog.models import Measurement

measurements = Blueprint('measurements', __name__, template_folder='templates')


class List(MethodView):
    cls = Measurement

    def get(self):
        measurements = self.cls.objects.all()
        return render_template('measurements/list.html', measurements=measurements)


class Detail(MethodView):

    def get_context(self, creator=None):
        form_cls = model_form(Measurement, exclude=('id', 'created_at', 'comments'))

        if creator:
            measurement = Measurement.objects.get_or_404(creator=creator)
            if request.method == 'POST':
                form = form_cls(request.form, inital=measurement._data)
            else:
                form = …
