问 Django:我如何创建多个选择表单？

EN

我认为 CheckboxSelectMultiple 应该根据你的问题来工作。

在您的 forms.py 中，编写以下代码：

from django import forms
class CountryForm(forms.Form):
    OPTIONS = (
        ("AUT", "Austria"),
        ("DEU", "Germany"),
        ("NLD", "Neitherlands"),
    Countries = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,
                                          choices=OPTIONS)

在您的 views.py 中，定义以下函数：

def countries_view(request):
    if request.method == 'POST':
        form = CountryForm(request.POST)
        if form.is_valid():
            countries = form.cleaned_data.get('countries')
            # do something with your results
    else:
        form = CountryForm
    return render_to_response('render_country.html', {'form': form},
                              context_instance=RequestContext(request))

在你的 render_country.html 里

<form method='post'>
    {% csrf_token %}
    {{ form.as_p }}
    <input type='submit' value='submit'>
</form>

我是这样做的：

forms.py

class ChoiceForm(ModelForm):
    class Meta:
        model = YourModel
    def __init__(self, *args, **kwargs):
        super(ChoiceForm, self).__init__(*args, **kwargs)
        self.fields['countries'] =  ModelChoiceField(queryset=YourModel.objects.all()),
                                             empty_label="Choose a countries",)

urls.py

from django.conf.urls.defaults import * 
from django.views.generic import CreateView
from django.core.urlresolvers import reverse
urlpatterns = patterns('',
    url(r'^$',CreateView.as_view(model=YourModel, get_success_url=lambda: reverse('model_countries'),
        template_name='your_countries.html'), form_class=ChoiceForm, name='model_countries'),)

your_countries.html

<form action="" method="post">
    {% csrf_token %}
    {{ form.as_table }}
    <input type="submit" value="Submit" />
</form> 

这在我的例子中很好，如果你需要更多的东西，就问我吧！！

关于我的第二个问题，这是解决办法。扩展类：

from django import forms
from django.utils.encoding import force_unicode
from itertools import chain
from django.utils.html import escape, conditional_escape
class Select(forms.Select):
    A subclass of Select that adds the possibility to define additional 
    properties on options.
    It works as Select, except that the ``choices`` parameter takes a list of
    3 elements tuples containing ``(value, label, attrs)``, where ``attrs``
    is a dict containing the additional attributes of the option.
    def render_options(self, choices, selected_choices):
        def render_option(option_value, option_label, attrs):
            option_value = force_unicode(option_value)
            selected_html = (option_value in selected_choices) and u' selected="selected"' or ''
            attrs_html = []
            for k, v in attrs.items():
                attrs_html.append('%s="%s"' % (k, escape(v)))
            if attrs_html:
                attrs_html = " " + " ".join(attrs_html)
            else:
                attrs_html = ""
            return u'<option value="{0}"{1}{2}>{3}</option>'.format(
                escape(option_value), selected_html, attrs_html, 
                conditional_escape(force_unicode(option_label))
            return u'<option value="%s"%s%s>%s</option>' % (
                escape(option_value), selected_html, attrs_html,
                conditional_escape(force_unicode(option_label)))
        # Normalize to strings.
        selected_choices = set([force_unicode(v) for v in selected_choices])
        output = []
        for option_value, option_label, option_attrs in chain(self.choices, choices):
            if isinstance(option_label, (list, tuple)):
                output.append(u'<optgroup label="%s">' % escape(force_unicode(option_value)))
                for option in option_label:
                    output.append(render_option(*option))
                output.append(u'</optgroup>')
            else:
                output.append(render_option(option_value, option_label,
                    option_attrs))
        return u'\n'.join(output)
class SelectMultiple(forms.SelectMultiple, Select):
