Django：模型外鍵和一個selectbox小部件

Question

我有2個模型Worker和Position當我添加一個新worker時，應該有selectbox，其位置在Positions模型中列出。

我嘗試使用“ Select小部件，但django失敗， no such property異常。

楷模

# Position model
class Position(models.Model):
    p_name   = models.CharField(max_length = 40, unique = True, verbose_name = 'Position')
    p_salary = models.IntegerField(max_length = 11, verbose_name = 'Salary')

    fields = ('p_name', 'p_salary')

# Worker model
class Worker(models.Model):
    w_name     = models.CharField(max_length = 40, verbose_name = 'Name')
    w_lastname = models.CharField(max_length = 40, verbose_name = 'Lastname')
    w_position = models.ForeignKey(to = Position, to_field = 'p_name', verbose_name = 'Position')
    w_dept     = models.ForeignKey(to = Department, to_field = 'd_name' verbose_name = 'Department')

形成

class WorkerForm(ModelForm):
    class Meta:
        model = Worker

        widgets = {
            'w_name'    : TextInput(attrs = {'class': 'e name'}),
            'w_lastame' : TextInput(attrs = {'class': 'e lastname'}),
            'w_position': Select(attrs = {'class': 'e position'}),
            'w_dept'    : Select(attrs = {'class': 'e department'}),
        }

admin.py中的定義

class WorkerAdmin(admin.ModelAdmin):
    form = WorkerForm


list_display = ('w_name', 'w_lastname', 'w_position', 'w_dept') 

怎么根據外鍵使選擇框出現問題？

Answer 1

您可以嘗試在表單內重新聲明表單的字段（確保使用與Model中相同的名稱），然后在其中設置小部件和屬性？
