How to render my TextArea with WTForms?

Question

To render my textareafield with a specified number of columns and rows with WTForms, how do I set the number of columns and rows? I followed the instructions from this question but it didn't work:

How to specify rows and columns of a <textarea > tag using wtforms

I tried adding a widget but it didn't work:

class AForm(Form):     name = TextField('Name', [validators.Length(min=4)])     title = TextField('Title', [validators.Length(min=4)])     text = TextAreaField('Text', widget=TextArea(row=70, cols=11))     phonenumber = TextField('Phone number')     phonenumberhide = BooleanField('Display phone number on site')     price = TextField('Price')     password = PasswordField('Password')     email = TextField('Email', [         validators.Length(min=6, message=_('Little short for an email address?')),         validators.Email(message=_('That\'s not a valid email address.'))     ]) 

TypeError: object.new() takes no parameters

Very old question, but since the WTF-Form documentation isn't clear I'm posting my working example. OP, hope you are not still working on this. :-)

form

from flask_wtf import Form from wtforms.fields import StringField from wtforms.widgets import TextArea  class PostForm(Form):     title = StringField(u'title', validators=[DataRequired()])     body = StringField(u'Text', widget=TextArea()) 

template

{% extends "base.html" %} {% block title %}Create Post{% endblock %} {% block content %} <H3>Create/Edit Post</H3> <form action="" method=post>    {{form.hidden_tag()}}    <dl>       <dt>Title:       <dd>{{ form.title }}       <dt>Post:       <dd>{{ form.body(cols="35", rows="20") }}}    </dl>    <p>       <input type=submit value="Publish"> </form> {% endblock %}
