AttributeError: 'Test' object has no attribute '__name__'

Question

This is the app.py. i faced this problem on my main project so i created a spearate test project to test it. and it occures again. here i tried to make a database in mongo then create a form out of it. pretty straight forward but no idea why the error happend

from flask_mongoengine.wtf import model_form
from flask_mongoengine import MongoEngine
from flask import render_template,request,Blueprint,Flask

app=Flask(__name__)
db= MongoEngine()

app.config\['MONGODB_SETTINGS'\]={'db':'project_database','host':'localhost','port':27017,'alias':'default'}
\#assign app to database
db.init_app(app)

class Test1(db.Document):
in1=db.StringField()
in2=db.StringField()
in3=db.StringField()

@app.route('/',methods=\['GET','POST'\])
def index():
test=model_form(Test1())
return render_template('inedx.html',test=test)

app.run(debug=True)

This is the error

I wanted to make a ModelForm from Mongo Document. But I have no idea what is the problem

Answer 1

Found the solution. pretty dumb that I didn't notice. but here is the right way

def index():
    test=model_form(Test1)
    test=test()
    return render_template('inedx.html',test=test)
