'forms.ContactForm object' has no attribute 'hidden_tag'

Question

I am trying to create a contact form using flask but keep getting this error when the page is rendered.

\'forms.ContactForm object\' has no attribute \'hidden_         


        

Answer 1

It took me some time to fix this.

First import Form, fields, bootstrap as:

from flask_wtf import Form
from wtforms import StringField #etc
from flask_bootstrap import Bootstrap

Config secret key and bootstrap

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret key'
Bootstrap(app)

create your form as your used to:

class ContactForm(Form):
  name = TextField("Name", [validators.Required()])
  email = TextField("Email",[validators.Required(), validators.email()])
  subject = TextField("Subject", [validators.Required()])
  message = TextAreaField("Message", [validators.Required()])
  submit = SubmitField("Send")

Nothing special in the routing aswell, just return it normaly.

In the html:

{% extends "bootstrap/base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
    {% if form %}
        {{ wtf.quick_form(form, ) }}
    {% endif %}

And that's it. Hope you find some (or all) of it useful.
