我正在制作我的第一个DRF api，当我试图使用GET请求访问我的数据时，我得到了一个奇怪的TypeError，我得到了这个错误。
'类型'对象不是可迭代的
下面是一些代码片段。
models.py
from django.db import models
# Create your models here.
class Expediteur(models.Model):
nom = models.CharField(max_length=50)
prenom = models.CharField(max_length=100)
adresse = models.CharField(max_length=200)
tel = models.IntegerField()
