Django：将一个已经填充的字段作为表单上的查询。 Ajax的选择

Question

我无法将已填充的字段用作表单上的查询。 我正在使用ajax-select来渲染字段。

forms.py

class FormMakeOccurrence(forms.ModelForm):

    class Meta:
        model = ManageOccurrence
        fields = ('attribute', 'item', 'place')

    place  = make_ajax_field(ManageOccurrence,'place','places', help_text=None)
    typeplace = make_ajax_field(TypePlace,'name','tipos_lugares', help_text=None)
    quarter = make_ajax_field(Quarter,'name','blocos', help_text=None)

lookup.py

class PlaceLookup(LookupChannel):

    model = Place

    def get_query(self,q,request):
        return Place.objects.filter(Q(name__icontains=q) | Q(typePlace__name__exact="AN FILLED FIELD") | Q(quarter__name__exact="AN FILLED FIELD"))

class TypePlaceLookup(LookupChannel):

    model = TypePlace

    def get_query(self,q,request):
    return TypePlace.objects.filter(Q(name__icontains=q)).order_by('name')

models.py

class ManageOccurrence(models.Model):


    attribute = models.ForeignKey(Attribute)
    item = models.ForeignKey(TypeItem)
    place = models.ForeignKey(Place)
    ... other fields

class Place(models.Model):
    name = models.CharField(max_length=30)
    typePlace = models.ForeignKey(TypePlace)
    quarter = models.ForeignKey(Quarter)

所以我想弄清楚，做这项工作的好方法是什么。

我需要先填写季度，所以typePlace。要到达正确的位置，要获得正确的属性以填充正确的项目。
