如何将多对多复选框表单小部件返回到多对多复选框表单，该表单由我的模板上的外键输入？

FRUITS
“复选框”苹果
“复选框”香蕉
“复选框”芒果

VEGETABLES
“复选框”白菜
“复选框”brocolli
“复选框”壁球
MEAT
“复选框”牛排
“复选框”猪肉 “复选框”肉

而不是：
“复选框”苹果
“复选框”香蕉
“复选框”芒果
“复选框”白菜
“复选框”brocolli
“复选框”壁球 “复选框”牛排
“复选框”猪肉 “复选框”肉

Answer 1

你的view.py不正确

foods_form = FoodsForm()
if foods_form.isvalid():
     food = foods_form.cleaned_data['foods']
context_dict['foods_form'] = foods_form
context_dict['food'] = food
return render(request, template, context_dict)

并在index.htm

中

{% for x in food %}
<div class="col-md-6">
  {{ certs }}
</div>
{% endfor %}

Django表单许多Tto Many字段由外键隔离
