希望对您有所帮助。似乎您想要的是提供一组经过筛选的节，以便在构建表单时可以使用初始参数：
def agregar_producto(request):
if request.method == "POST":
modelform = AgregarProducto(request.POST,request.FILES,user=request.user)
print modelform
if modelform.is_valid():
modelform.save()
return redirect("/editar-perfil/")
else:
modelform = AgregarProducto(initial={'user':request.user}) #pass in the authenticated user
return render(request, "home/AgregarProducto.html", {"form":modelform})
class AgregarProducto(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(AgregarProducto, self).__init__(*args, **kwargs)
if kwargs.get('initial'):
user = kwargs.get('initial').get('user')
if user:
sections = secciones.objects.filter(user_id=user.id)
self.fields['secciones'].choices = [(s.id, s.name) for s in sections]
self.fields['client'].choices = [('', '---------')]+self.fields['client'].choices #this adds an "empty" option

这将仅在下拉列表中显示用户的节，使用id作为值，使用名称作为显示。似乎您想要的是提供一组经过筛选的节，因此您可以在构建表单时使用初始参数：

这将只在下拉列表中显示用户的部分，使用id作为值，使用名称作为显示。谢谢朋友，但我需要的是在模板中只保留用户登录的部分，而不是所有用户的部分，如果您能帮助我，我将不胜感激。您可以使用wrapper或自定义wrapper来要求用户必须登录。您可以在这一行中看到：
Secciones.objects.filter（user=request.user）SeccionesSecciones.objects.filter（user=request.user）密码。请参阅我的更新。。。
