Question

我想创建一个登录应用程序。我正在使用Flask和PyMongo以及mongoalchemy作为登录应用程序。当我运行该程序时，代码显示以下错误。追溯（最近一次通话）：

raise FieldNotRetrieved(self._name)

mongoalchemy.exceptions.FieldNotRetrieved：名称

from flask import Flask,request,render_template
from flask_pymongo import PyMongo
from flask_mongoalchemy import MongoAlchemy
from flask_wtf import FlaskForm
from wtforms import TextField,BooleanField,StringField,PasswordField,validators
from wtforms.validators import InputRequired
app = Flask(__name__)
app.config['SECRET_KEY']='thisissecretkey'
app.config['MONGOALCHEMY_DATABASE'] = 'test'
app.config["MONGO_URI"] = "mongodb://localhost:27017/test"

db = MongoAlchemy(app)

class Author(db.Document):
    name = db.StringField(required=True)
    password = db.StringField(required=True)

class Reg(FlaskForm):
	name=StringField("name",validators=[InputRequired()])
	password=PasswordField("password",validators=[InputRequired()])

@app.route("/index",methods=['GET','POST'])
def index():
	form = Reg()
	if request.method=='POST':
		if form.validate():
			Author(request.form["name"],request.form["password"]).save()
			return "user is created"
		return "user is not created"
	return render_template('check.html',form=form)


if __name__=='__main__':
	app.run(debug=True)

--this is Flask-Form page----
{% from "_formhelpers.html" import render_field %}
<!DOCTYPE html>
<html>
<head>
	<title></title>
</head>
<body>
	<form method="POST" action="/index">
		<dl>
		{{ form.hidden_tag() }}
		{{ render_field(form.name) }}
		{{ render_field(form.password) }}
		</dl>
		<p><input type="submit" name="submit"></p>
	</form>
</body>
</html>

引发FieldNotRetrieved（self._name）mongoalchemy.exceptions.FieldNotRetrieved：name。错误
