我有一个客户和治疗数据库，每个客户可以有多种治疗方法。 问题是，治疗在DB中丢失了其客户价值，而不是客户的ID，该值只是NULL。
这在以下代码中发生：
def get_treatment(request, treatment_id):
customer = Treatment.objects.get(id=treatment_id).customer
if request.POST:
form = TreatmentForm(request.POST, instance=Treatment.objects.get(id=treatment_id))
if form.is_valid():
form.save() #***This is where it happens***
return HttpResponseRedirect('/')
else:
form = TreatmentForm(instance=Treatment.objects.get(id=treatment_id))
return render_to_response('new_treatment.html',
{"form" : form,
"customer_name" : customer,
},
RequestContext(request))
任何人都可以解释这种奇怪的行为吗？

我的猜测是，您在发布表单时没有为客户提交值。空白是有效值，因为您有required=False。因此，Django在保存表单时将客户设置为None。
如果您不希望customer字段可编辑，则根本不应将其包含在表单中。您可以使用exclude。
class TreatmentForm(forms.ModelForm):
class Meta:
model = Treatment
exclude = ['customer']
使用exclude可能会有点危险。您将来可能会向模型添加私有字段，并且会因为您忘记将其添加到exclude而自动添加到表单中。您可以设置fields，然后退出customer。
class TreatmentForm(forms.ModelForm):
class Meta:
model = Treatment
fields = ['skin_hue_finding', 'skin_hue_area', ... <all other fields>]
但是在这种情况下你可能不想这样做，因为你有很多字段。
