抱歉，如果这是一个简单的修复，我的内联表单集有 2 个问题：
保存无效对象（不满足唯一性要求）会引发错误页面，而不是在表单中显示错误。
有一次，我在保存无效对象时正确显示了错误，但是当我尝试保存有效对象时，我会收到一条错误消息，提示 members.department 为空。这就是为什么我把“例如在实例中”但是现在我遇到了保存无效对象时不显示错误的新问题。
删除有效对象时我遇到了同样的问题。该对象被删除，但我仍然得到一个错误页面......
我迷路了。
保存无效对象时，我得到：
The Membership could not be created because the data didn't validate.
删除有效对象时，我得到：
[u'Select a valid choice. That choice is not one of the available choices.']
模型：
class Membership(models.Model):
project = models.ForeignKey(Project)
department = models.ForeignKey(Department)
employee = models.ForeignKey(Employee)
role = models.ManyToManyField(Role, blank=True, null=True)
class Meta:
unique_together = (("project", "employee",),)
视图.py
def employee_edit(request, employee_id):
i = get_object_or_404(Employee, pk=employee_id)
MembershipForm = make_membership_form(i)
MembershipFormSet = inlineformset_factory(Employee, Membership, exclude='department', extra=1, form=MembershipForm)
if request.method == "POST":
f = MembershipFormSet(request.POST, instance=i)
if f.is_valid():
instances = f.save(commit=False)
for instance in instances:
instance.department = i.department
instance.save()
f.save_m2m()
return render_to_response('dbtest/edit.html', {'item': i, 'formset': f, }, context_instance=RequestContext(request))
else:
f = MembershipFormSet(instance=i)
return render_to_response('dbtet/edit.html', {'item': i, 'formset': f, }, context_instance=RequestContext(request))
def make_membership_form(i):
class MembershipForm(forms.ModelForm):
project = forms.ModelChoiceField(queryset=Project.objects.filter(department=i.department))
class Meta:
model = Membership
exclude = ('department', 'employee')
unique_together = (("project", "employee",),)
return MembershipForm
