Question

在我的项目中，我的操作很复杂，因此当我选择部门时，我保存该项目的ID并绑定到表以显示插入的记录，因此当我绑定部门时，我想绑定该部门的名称而不是该ID 。请帮助我。

Model.py

list(dictionary.items())

forms.py

class Department(models.Model):
  ACTIVE = 1
  INACTIVE = 2
  DELETED = 3
  STATUS_CHOICES = (
    (ACTIVE, 'active'),
    (INACTIVE, 'inactive'),
    (DELETED, 'deleted'),
  )
  department_id = models.AutoField(primary_key=True)
  department_name = models.CharField(max_length=30, null=False)
  created_on = models.DateTimeField(auto_now_add=True,  null=False)
  created_by = models.CharField(max_length=100, null=False)
  modified_on = models.DateTimeField(auto_now_add=True)
  modified_by = models.CharField(max_length=100)
  status = models.CharField(max_length=10, null=False, choices=STATUS_CHOICES)

 objects = UserManager()

  class Meta:
    managed = True
    db_table = "ht_department"

  def __str__(self):
    return self.department_id

html

class EmpForm(ModelForm):
  class Meta:
      model = Employee
      fields = ["employee_id", "Name", "designation", "department_id", "manager_id", 
       "date_of_joining","date_of_birth", "location_id", "email", "contact_number",                  
         "password", "created_by", "modified_by", "status",   "user_type"]



class dept(ModelForm):
   class Meta:
      model = Department
      fields = ["department_id", "department_name", "created_by", "modified_by", "status"]


class EmpLoc(ModelForm):
  class Meta:
    model = Location
    fields = ["location_id", "location_name", "created_by", "modified_by", "status"]

这是我更新的EmployeeModel代码：

      <tbody id="myTable">
                {% for employee in employees %}

                <tr>
                    <td>{{ employee.employee_id}}</td>
                    <td>{{ employee.Name}}</td>
                    <td>{{ employee.designation}}</td>
                    <td>{{ employee.department_id}}</td>
                    <td>{{ employee.manager_id}}</td>
                    <td>{{ employee.location_id}}</td>
                    <td>

                        <a href="#editEmployeeModal" class="edit" data-toggle="modal"><i class="material-icons" data-toggle="tooltip" title="Edit">&#xE254;</i></a>
                        <a href="#deleteEmployeeModal" class="delete" data-toggle="modal"><i class="material-icons" data-toggle="tooltip" title="Delete">&#xE872;</i></a>
                    </td>
                </tr>
          {% endfor %}
            </tbody>

您应该将员工中的department_id字段更新为外键，以便获取部门名称，因此它将为：

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

然后在模板中获取部门名称

{{employee.department.department_name}}

mysql表如何获得关于该id的名称方面？
