我正在尝试在 1 个视图中呈现 2 个表单集并得到一个
u'ManagementForm data is missing or has been tampered with
错误。网页呈现正常,当我点击提交时数据确实将值传递给数据库,但我认为我传递管理表单数据不正确。
我还想补充一点,我使用了“ https://docs.djangoproject.com/en/dev/topics/forms/formsets/ ”,但它没有提供足够的文档来传递管理表单数据。此外,我的选项和结果表单集具有相同的外键。如果您在传递管理表单数据时发现任何问题,或者代码是否有任何其他问题,请告诉我。
下面是我的views.py和html:
视图.py
def option(request):
if request.method == "POST":
optionForm = OptionForm(request.POST)
outcomeForm = OutcomeForm(request.POST)
if optionForm.is_valid():
new_option = optionForm.save()
new_outcome = outcomeForm.save()
optionInlineFormSet = OptionFormSet(request.POST, request.FILES, instance=new_option, prefix='option')
outcomeInlineFormSet = OutcomeFormSet(request.POST, request.FILES, instance=new_outcome, prefix='outcome')
if optionInlineFormSet.is_valid() and outcomeInlineFormSet.is_valid:
optionInlineFormSet.save()
outcomeInlineForSet.save()
return HttpResponseRedirect(reverse(outcome))
else:
optionForm = OptionForm()
outcomeForm = OutcomeForm()
optionInlineFormSet = OptionFormSet()
outcomeInlineFormSet = OutcomeFormSet()
return render_to_response("option.html", {'optionForm': optionForm, 'outcomeForm': outcomeForm, 'optionInlineFormSet': optionInlineFormSet, 'outcomeInlineFormSet': outcomeInlineFormSet}, context_instance=RequestContext(request))
html:
<form class="option_form" action="{% url option %}" method="post">{% csrf_token %}
{{ optionInlineFormSet.management_form }}
{{ outcomeInlineFormSet.management_form }}
{{ optionForm.as_table }}
{{ outcomeForm.as_table}}
<input type="submit" name="submit" value="Submit" class="button">
</form>
