Django不生成多个下拉列表

Question

我正在尝试为模型添加多个下拉列表，但Django没有生成多个下拉列表.. 这是model.py文件。下拉显示为＆＃39;资格＆＃39;现场，但部门＆＃39;没有以表格形式显示.. 这是模板文件。

<table style="width:100%">
        {% for field in form %}

          <tr>
            <td>{{ field.label_tag }}</td>
            <td>{{ field }}</td>
          </tr>

    {% endfor %}
    </table>

这里是forms.py

class EmployeeForm(forms.ModelForm):
    class Meta:
        model = Employee
        fields = ['regno','fname','lname','ffname','flname','qualification', 'num', 'email','city','contact','alternatecontact','fathercontact','joiningdate','qualification', 'department', 'experience','lastemployer','picture','isteaching','dob','status','address']

model.py

class StaffEducation(models.Model):
    id = models.AutoField(db_column='id', primary_key=True)
    title = models.CharField(db_column='title', max_length=100)
    def __str__(self):
        return self.title

class Department(models.Model):
    id = models.AutoField(db_column='id', primary_key=True)

    experience = models.CharField(db_column='experience', max_length=100)
    lastemployer = models.CharField(db_column='lastemployer', max_length=100)
    picture = models.ImageField(db_column='picture')
    isteaching = models.BooleanField()
    dob = models.DateField(db_column='dob')
    status = models.BooleanField(db_column='status')
