Flask wtform RadioField label does not render

will help you I don't use quick_form but if you are going to render the field label, you need to place the {{ field.foo.label }} and {{ field.foo }} for the field label to show, something like this works for me:
code :
<form method="POST" action="/">
    {{ form.hidden_tag() }}
    <h3>{{ form.example.label }}</h3>
    <p>{{ form.example }}</p>
    <h3>{{ form.key.label }}</h3>
    <p>{{ form.key }}</p>
    {{ form.submit }}
{% import "bootstrap/wtf.html" as wtf %}

<h3>{{ form.example.label }}</h3>
<p>{{ wtf.form_field(form.example) }}</p>

<h3>{{ form.key.label }}</h3>
<p>{{ wtf.form_field(form.key) }}</p>

{{ form.submit }}

With these it helps This is not done in the template, you have to do it on the Form object before you call render_template().
For example:
code :
form.gender.data = 'male'

wish helps you The Issue appears to have been caused due to the fact that WTForm expects the Value field, to be a String as opposed to an Integer

it helps some times When reviewing the WTForms documentation I had initially missed the part underneath the RadioFields description which describes how the list of radio buttons are rendered by default. I'll show it below:
code :
{% for subfield in form.radio %}
        <td>{{ subfield }}</td>
        <td>{{ subfield.label }}</td>
{% endfor %}
{% extends "base.html.j2" %}

{% block content %}

<form action="/test" method="POST">
  {% if test_form.errors %}
    {{ test_form.errors }}
  {% endif %}

  {{ test_form.csrf_token }}
  {% for qa in test_form.question_attempts %}
    <div class="well">
        {{ qa.label }}
        <ol type="A">
        {% for subfield in qa.answer_selection %}
            {{ subfield }}
            {{ subfield.label }}
        {% endfor %}
        {{ qa.question_id }}
  {% endfor %}
  {{ test_form.submitfield(class="btn btn-success") }}

{% endblock %}
How do I pass a variable from a function to a WTForm? I use the variable to choose RadioField choices

How do I pass a variable from a function to a WTForm? I use the variable to choose RadioField choices

hope this fix your issue The code within the class definition of your form is only ever executed once when the module is initially loaded and at that point the local variable level does not exist. Even if it did exist at that point, you would only be setting the class definition once whereas you want the ability to alter the form choices every time it is displayed. This can easily be achieved in your view function. Don't set the field choices in the form class but set them on the form itself after it has been created by setting the value of the field choices attribute. Given that that the number of choices available for each level happens to equal the value of that level, you can use list slicing to generate this list.
code :
class ZWOForm(Form):
    zwotitle = TextField('Title', [validators.Length(min=3, max=50)])
    zwotags = TextField('Tags', [validators.Length(min=3, max=50)])
    category = TextField('Category (Your Choice)', [validators.Length(min=3, max=50)])
    zwolevel = RadioField('Viewing Level', choices=[], default=1)
    zwodescription = TextAreaField('Description', [validators.Length(min=3, max=200)])      

@app.route('/createzwo/', methods=["GET","POST"])
def create_zwo():        
        form = ZWOForm(request.form)
        all_choices = [('1','Public'),('2','Private'),('3','Team')]
        choices = all_choices[:session["level"]]
        form.zwolevel.choices = choices

        if request.method == "POST" and form.validate():
        return render_template("createzwo.html", form=form)
