Django 1.9不過濾查詢結果

Question

我有一個表單，其中一個選擇輸入的選項與另一個表相關。

一切完美，但知道我要排除一些選項，讓我在forms.py以下科德：

class employeesForm(forms.ModelForm): 
    def __init__(self, *args, **kwargs): 
     super(employeesForm, self).__init__(*args, **kwargs) 
     self.fields['num_employee'].required = False 
     self.fields['id_ignition'].required = False 
     self.fields['picture'].required = False 
     self.fields['source'].required = False 

    class Meta: 
     model = Employees 
     ccOptions = CostCenter.objects.all().values_list('id_costCenter', 'area') 
     jcOptions = JobCode.objects.all().values_list('id_jobCode', 'gmpName') 
     ntOptions = Nations.objects.all().values_list('nationality') 
     esOptions = EmpSources.objects.all().values_list('source') 
     from django.db.models import Q 
     # in this line 
     stOptions = Status.objects.exclude(Q(id_status=2) | Q(id_status=3)).values_list('status') 

     fields = [ 
      'num_employee', 
      'fullName', 
      'shortName', 
      'gender', 
      'birthday', 
      'initday', 
      'id_status', 
      'nationality', 
      'picture', 
      'source', 
     ] 
     widgets = { 
      'num_employee': forms.NumberInput(attrs={'class': 'form-control', 'name': 'num_employee'}), 
      'fullName': forms.TextInput(attrs={'class': 'form-control', 'name': 'fullName', 'placeholder': 'Angel Rafael Ortega Vazquez'}), 
      'shortName': forms.TextInput(attrs={'class': 'form-control', 'name': 'shortName', 'placeholder': 'Rafael Ortega'}), 
      'gender': forms.CheckboxInput(attrs={'class': 'form-control', 'name': 'gender'}), 
      'birthday': forms.DateInput(attrs={'class': 'form-control', 'name': 'birthday'}), 
      'initday': forms.DateInput(attrs={'class': 'form-control', 'name': 'initday'}), 
      # also here 
      'id_status': forms.Select(choices=stOptions, attrs={'class': 'form-control', 'name': 'id_status'}), 
      'nationality': forms.Select(choices=ntOptions, attrs={'class': 'form-control', 'name': 'nationality'}), 
      'picture': forms.ClearableFileInput(attrs={'class': 'form-control', 'name': 'picture'}), 
      'source': forms.Select(choices=esOptions, attrs={'class': 'form-control', 'name': 'source'}), 
     } 

的問題是，即使在排除選項，我選擇渲染劇照完整的表格。

我甚至嘗試過濾只有一個參數，但結果是一樣的。 我也刪除了我的瀏覽器緩存，只是爲了放棄這種可能性，但並沒有改變。

ModelForms中的相關對象是ModelChoiceField s。您需要指定queryset=...屬性。

例子：

class Department(models.Model): 
    name = models.CharField() 
    active = models.BooleanField() 


class Employee(models.Model): 
    name = models.CharField() 
    department = models.ForeignKey(Department) 


class EmployeeForm(forms.ModelForm): 
    class Meta: 
     model = Employee 
     exclude = [] 

    def __init__(self, *args, **kwargs): 
     super(EmployeeForm, self).__init__(*args, **kwargs) 
     self.fields['department'].queryset = Department.objects.filter(active=True)
