from django import forms

class GenderForm(forms.Form):
    CHOICES = (
        ( M ,  Male ),
        ( F ,  Female ),
    )
    choice = forms.ChoiceField(choices=CHOICES, widget=forms.RadioSelect())

Remember, Django documentation is your friend!

Dynamically Changing Choices If you want to be able to dynamically create the form, it might be a good idea to use ModelForm instead of forms.Form. Here s an example:

from django.db import models
from django.forms import ModelForm
from django import forms

class Answer(models.Model):
    answer = models.CharField(max_length=100)

    def __unicode__(self):
        return self.answer

class Question(models.Model):
    title = models.CharField(max_length=100)
    answers = models.ManyToManyField( Answer )

class QuestionForm(ModelForm):
    class Meta:
        model = Question
        fields = ( title ,  answers )
        widgets = {
             answers : forms.RadioSelect(),
        }

2. 您认为,在形式上,具体指明使用:

question = Question.objects.order_by( ? )[0]
form = QuestionForm(instance=question)

The form will then use the answers associated with that Question (in this case randomly chosen) and pass the form to the templates context as usual.

There s a good example how to do this here: https://code.djangoproject.com/wiki/CookBookNewFormsDynamicFields

Basically, your form code will follow this pattern:

from django import forms

class MyForm(forms.Form):
    static_field_a = forms.CharField(max_length=32)
    static_field_b = forms.CharField(max_length=32)
    static_field_c = forms.CharField(max_length=32)

    def __init__(self, dynamic_field_names, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)

        for field_name in dynamic_field_names:
            self.fields[field_name] = forms.CharField(max_legth=32)    # creates a dynamic field

Example usage:

>>> dynamic_fields = ( first_name ,  last_name ,  company ,  title )
>>> my_form = MyForm(dynamic_field_names=dynamic_fields)
>>> my_form.as_ul()
u <li><label for="id_static_field_a">Static field a:</label> <input id="id_static_field_a" type="text" name="static_field_a" maxlength="32" /></li>
<li><label for="id_static_field_b">Static field b:</label> <input id="id_static_field_b" type="text" name="static_field_b" maxlength="32" /></li>
<li><label for="id_static_field_c">Static field c:</label> <input id="id_static_field_c" type="text" name="static_field_c" maxlength="32" /></li>
<li><label for="id_first_name">First name:</label> <input id="id_first_name" type="text" name="first_name" maxlength="32" /></li>
<li><label for="id_last_name">Last name:</label> <input id="id_last_name" type="text" name="last_name" maxlength="32" /></li>
<li><label for="id_company">Company:</label> <input id="id_company" type="text" name="company" maxlength="32" /></li>
<li><label for="id_title">Title:</label> <input id="id_title" type="text" name="title" maxlength="32" /></li>

That ll render a form with the following text inputs:

• Static field a
• Static field b
• Static field c
• First name
• Last name
• Company
• Title

Just use forms.ChoiceField(), or whatever you want, instead of forms.TextField().
