我想使用POST数据来部分预填充下一个表单。
我在一个页面上有一个表格......
<form method="POST" action='{% url 'screen_many' %}'>
将内容传递给显示第二种形式的视图。
def screen_many(request):
#...
if request.method == 'POST':
form = SurveyForm(request.POST)
if form.is_valid():
saved = form.save(commit=False)
saved.save()
return HttpResponseRedirect('/')
else:
form = SurveyForm(initial={'student': request.POST['selected_student']})
当然，if分支被采用，第二种形式抱怨验证错误。
编辑：根据要求，我的表格代码......
