如何在模板中显示ChoiceField？
摘录自
forms.py：views.py：index.html
class ContForm():
KafChoices = [(kaf.id, kaf.name) for kaf in Kaf.objects.all()]
kaf = forms.ChoiceField(choices = KafChoices, required = True)
class Meta:
model = Cont
def index(request):
return render_to_response('db3/index.html',
{'form': ContForm()},
context_instance=RequestContext(request))
：
{{ form.kaf }}
我得到以下输出： django.forms.fields.ChoiceField 对象位于 0x01A110D0
而不是通常的领域。怎么了？
Excerpts from
forms.py:
class ContForm():
KafChoices = [(kaf.id, kaf.name) for kaf in Kaf.objects.all()]
kaf = forms.ChoiceField(choices = KafChoices, required = True)
class Meta:
model = Cont
views.py:
def index(request):
return render_to_response('db3/index.html',
{'form': ContForm()},
context_instance=RequestContext(request))
index.html:
{{ form.kaf }}
I get following output:
django.forms.fields.ChoiceField object at 0x01A110D0
instead of usual field. What's wrong?

因为
ContForm不是继承自forms.Form吗？编辑：看起来像一个模型表单，在这种情况下
ContForm(forms.ModelForm)，但无论哪种方式，如果您不从表单类继承，所有form.kaf都会做正在拉起这个 python 对象，它不知道如何处理自己。Because
ContFormisn't inheriting fromforms.Form?Edit: looks like a modelform, in which case
ContForm(forms.ModelForm), but either way if you don't inherit from the form classes allform.kafis doing is pulling up this python object that doesn't know what to do with itself.
