【问题描述】：
我在一个视图中有多个模型表单集。这用于编辑配置文件的现有数据并由用户添加新数据。当用户尝试编辑和保存数据时，数据没有保存在数据库中。我做错了什么？
views.py
def profile_edit(request,username):
profile_edit = get_object_or_404(User,username=username)
userprofile = get_object_or_404(UserProfile,user__username=username)
UserDegreeFormset = modelformset_factory(Degree,form = EditForm2,extra=1,validate_max=True,can_delete=True)
degree = Degree.objects.filter(user__username=username)
UserCertificateFormset = modelformset_factory(Certificate,form=EditForm4,extra=1,validate_max=True,can_delete=True)
certificate = Certificate.objects.filter(user__username=username)
UserSocialFormset = modelformset_factory(SocialMedia,form=EditForm5,extra=1,validate_max=True,can_delete=True)
sociallink = SocialMedia.objects.filter(user__username=username)
if request.user == profile_edit and request.user.is_authenticated:
if request.method == "POST":
form = EditForm(request.POST or None,instance=profile_edit)
form1 = EditForm1(request.POST or None,instance=userprofile)
form2 = UserDegreeFormset(request.POST or None,queryset= degree)
form4 = UserCertificateFormset(request.POST or None,queryset=certificate)
form5 = UserSocialFormset(request.POST or None, queryset=sociallink)
if form.is_valid() and form1.is_valid() and form2.is_valid() and form4.is_valid() and form5.is_valid():
form.save()
form1.save()
degs = form2.save(commit=False)
for obj in form2.deleted_objects:
obj.delete()
for deg in degs:
deg.user = profile_edit
deg.save()
certs = form4.save(commit=False)
for obj in form4.deleted_objects:
obj.delete()
for cert in certs:
cert.user = profile_edit
cert.save()
links = form5.save(commit=False)
for obj in form5.deleted_objects:
obj.delete()
for link in links:
link.user = profile_edit
link.save()
return redirect('profile_edit',username=username)
else:
form = EditForm(instance=profile_edit)
form1 = EditForm1(instance=userprofile)
form2 = UserDegreeFormset(queryset=degree)
form4 = UserCertificateFormset(queryset=certificate)
form5 = UserSocialFormset(queryset=sociallink)
context = {
'form':form,
'form1':form1,
'form2':form2,
'form4':form4,
'form5':form5,
}
return render(request,'userprofile/profile_edit.html', context)
else:
raise PermissionDenied
forms.py
class EditForm(forms.ModelForm):
email = forms.EmailField(label='Email Address',disabled=True)
class Meta:
model = User
fields = ('username','email','first_name','last_name',)
class EditForm1(forms.ModelForm):
date_of_birth = forms.DateField(widget=forms.SelectDateWidget)
class Meta:
model = UserProfile
fields = ('date_of_birth','phone_no','overall_rating','preferred_language',)
class EditForm2(forms.ModelForm):
class Meta:
model = Degree
exclude = ("user",)
class EditForm4(forms.ModelForm):
class Meta:
model = Certificate
fields = ('title','institution_name',)
class EditForm5(forms.ModelForm):
class Meta:
model = SocialMedia
fields = ('website_name','website_link',)
PS1：- 当我只使用一个模型 formset 时，它工作得很好。
PS2：- 没有显示错误。
