模板中有一个复选框,如果值包含在渲染中,默认情况下将选中该选项。它适用于1.10。
form.py:
class NewForm(forms.Form):
project = forms.ModelMultipleChoiceField(
widget=forms.CheckboxSelectMultiple,
queryset=Project.objects.filter(enable=True)
)
模板:
{% for p in form.project %}
<label for="{{ p.id_for_label }}">
<input type="checkbox" name="{{ p.name }}" id="{{ p.id_for_label }}"
value="{{ p.choice_value }}"
{% if p.choice_value|add:"0" in form.project.initial %} checked{% endif %}>
<p>{{ p.choice_label }}</p>
</label>
{% endfor %}
views.py:
def order_start(request, order_id):
if request.method == 'POST':
form = NewForm(request.POST)
if form.is_valid():
order.end_time = timezone.now()
order.save()
order.project = form.cleaned_data['project']
order.save()
return HttpResponsec(order.id)
else:
form = NewForm(initial={
'project': [p.pk for p in order.project.all()],
})
return render(request, 'orders/start.html', {'form': form, 'order': orderc})
当我升级到Django 1.11时,{{ p.name }}
和{{ p.choice_value }}
什么也没有返回。我知道1.11删除了choice_value
,但是如何解决这个问题?

作为@L_S的评论。我使用dir(form)
进行调试,form.project.data
中包含的所有值都是正确的代码:
{% for choice in form.project %}
<labelc for="{{ choice.id_for_label }}">
<input type="checkbox" name="{{ choice.data.name }}" id="{{ choice.id_for_label }}"
value="{{ choice.data.value }}"{% if choice.data.selected %} checked{% endif %}>
{{ choice.data.label }}
</label>
{% endfor %}
