我现在已经潜伏了很长一段时间,但我找不到解决问题的方法。 我为我的表单制作了自定义模板,现在,当我尝试提交表单时,我会在选择字段下选择:选择一个有效的选项。不是可用的选择之一。
我认为问题是因为我没有通过组织实例而是id。我尝试{{form.instance.organization}}然后我得到无应该是选择字段
views.py:
class AddNewView(generic.View):
formClass = AddNewForm
template_name = 'myapp/subscription_form.html'
def get(self, request):
groups = self.request.user.groups.values_list('id', flat=True).first()
form = self.formClass(groups, None)
return render(request, self.template_name, {'form': form})
def post(self, request):
groups = self.request.user.groups.values_list('id', flat=True).first()
form = self.formClass(groups, request.POST)
if form.is_valid():
subscription = form.save(commit=False)
organization = request.user.groups.values_list('id', flat=True).first()
input_user = self.request.user
stuff = form.cleaned_data['stuff']
description = form.cleaned_data['description']
subscription.save()
return render(request, self.template_name, {'form': form})
forms.py:
class AddNewForm(forms.ModelForm):
def __init__(self, groups,*args,**kwargs):
super (AddNewView, self ).__init__(*args,**kwargs)
self.fields['organization'].queryset = Organization.objects.filter(group=groups)
class Meta:
model = Subscription
fields = [
'organization',
'stuff',
'description',
]
models.py:
class Organization(models.Model):
d_number = models.CharField(max_length=25)
city = models.CharField(max_length=100)
group = models.ManyToManyField(Group, help_text="groups")
class Subscription(models.Model):
organization = models.ForeignKey(Group, help_text="which organization")
input_user = models.CharField(max_length=150)
input_date = models.DateTimeField(auto_now_add=True)
description = models.CharField(max_length=1000, null=True, blank=True, help_text='Description')
stuff = models.CharField(max_length=100)
模板:
