Customizing Django Forms Using the RadioSelect Widget

So, I use jQuery UI to exchange radio buttons , but I can not get Django to display my form as it is.

I need this structure:

<table>
    <tr>
        <td><label for="notify_new_friends">Notify when new friends join</label></td>
        <td class="radio">
            <input type="radio" name="notify_new_friends" id="notify_new_friends_immediately" value="1" checked="checked"/><label for="notify_new_friends_immediately">Immediately</label>
            <input type="radio" name="notify_new_friends" id="notify_new_friends_never" value="0"/><label for="notify_new_friends_never">Never</label>
        </td>
    </tr>
</table>

So, to summarize, I need radio buttons in the class (radio), where they have inputand label for.

When I create a form in my template using {{ profile_form.notify_new_friends }}, I get the following:

<ul>
    <li><label for="id_notify_new_friends_0"><input type="radio" id="id_notify_new_friends_0" value="0" name="notify_new_friends" /> Immediately</label></li>
    <li><label for="id_notify_new_friends_1"><input type="radio" id="id_notify_new_friends_1" value="1" name="notify_new_friends" /> Never</label></li>
</ul>

This is exactly what I want, with the exception of part of the list. So I tried to focus on it, which gives me labels formatted differently:

{% for item in profile_form.notify_new_friends %}
    {{ item }}
{% endfor %}

which gives me:

<label><input type="radio" name="notify_new_friends" value="0" /> Immediately</label>
<label><input type="radio" name="notify_new_friends" value="1" /> Never</label>

So, the problem here is that it stops using label forand starts using only labelto wrap it all up.

- , label label_tag .

{{ profile_form.notify_new_friends.0 }}
{{ profile_form.notify_new_friends.0.label_tag }}
{{ profile_form.notify_new_friends.0.label }}

- , ??

FYI, forms.py:

self.fields['notify_new_friends'] = forms.ChoiceField(label='Notify when new friends join', widget=forms.RadioSelect, choices=NOTIFICATION_CHOICES)

, jQuery.

// First remove the ul and li tags
$('.radio ul').contents().unwrap();
$('.radio li').contents().unwrap();
// Then move the input to outside of the label
$('.radio > label > input').each(function() {
    $(this).parent().before(this);
});
// Then apply the jQuery UI buttonset
$( ".radio" ).buttonset();

:

<ul>
    <li><label for="id_notify_new_friends_0"><input type="radio" id="id_notify_new_friends_0" value="0" name="notify_new_friends" /> Immediately</label></li>
    <li><label for="id_notify_new_friends_1"><input type="radio" id="id_notify_new_friends_1" value="1" name="notify_new_friends" /> Never</label></li>
</ul>

to:

<input type="radio" id="id_notify_new_friends_0" value="0" name="notify_new_friends" /><label for="id_notify_new_friends_0"> Immediately</label></li>
<input type="radio" id="id_notify_new_friends_1" value="1" name="notify_new_friends" /><label for="id_notify_new_friends_1"> Never</label></li>

, , , , 2 : RadioRenderer RadioInput. , .

-. , , , Django, (<label><input /></label>), ours (<label /><input />):

class CustomRadioInput(RadioInput):
    def render(self, name=None, value=None, attrs=None, choices=()):
        name = name or self.name
        value = value or self.value
        attrs = attrs or self.attrs
        if 'id' in self.attrs:
            label_for = ' for="%s_%s"' % (self.attrs['id'], self.index)
        else:
            label_for = ''
            choice_label = conditional_escape(force_unicode(self.choice_label))
            return mark_safe(u'%s<label%s>%s</label>' % (self.tag(), label_for, choice_label))

RadioRenderer, :

  • .
  • <li>, <ul>, :

- :

class RadioCustomRenderer(RadioFieldRenderer):
    def __iter__(self):
        for i, choice in enumerate(self.choices):
            yield CustomRadioInput(self.name, self.value, self.attrs.copy(), choice, i)

    def __getitem__(self, idx):
        choice = self.choices[idx]
        return CustomRadioInput(self.name, self.value, self.attrs.copy(), choice, idx)

    def render(self):
        return mark_safe(u'%s' % u'\n'.join([u'%s' % force_unicode(w) for w in self]))

Finally, explain that Django uses native rendering.

notify_new_friends = forms.ChoiceField(label='Notify when new friends join', widget=forms.RadioSelect(renderer=RadioCustomRenderer), choices=NOTIFICATION_CHOICES)

Please keep in mind: . Now the output of the radio button along with the inclusion <td>, so you need to create a table around it in your template, something like these lines:

<table>
  <tr>
    <td><label for="{{field.auto_id}}">{{field.label}}</label></td>
    <td>{{ field.errors }} {{field}}</td>
  </tr>
</table>

Try like this ,  I got it..

from django.forms.widgets import RadioFieldRenderer
from django.utils.encoding import force_unicode
from django.utils.safestring import mark_safe


class RadioCustomRenderer( RadioFieldRenderer ):
    def render( self ):
        return  mark_safe(u'%s' % u'\n'.join([u'%s'  % force_unicode(w) for w in self]))

in form

widgets = {
            'validity': forms.RadioSelect(renderer=RadioCustomRenderer),
        }
