【问题描述】：

我使用 Djanjo 框架创建了一个 Web 应用程序，然后当我尝试创建一个 REST API 时，在配置了所有相关文件（例如 models.py、admin.py、serializers.py、views.py 和 settings）之后.py。从 rest_framework 导入模型时显示错误。回溯如下：

ImportError: cannot import name 'employees' from 'rest_framework' (C:\Users\dmandal\AppData\Local\Continuum\anaconda3\lib\site-packages\rest_framework\__init__.py)*

serializer.py如下：

from rest_framework import serializers
from rest_framework import employees

class employeesSerializer(serializers.ModelSerializer):
    
    class Meta:
        model = employees
#        fields = ('firstname','lastname')
        fields = '__all__'

【问题讨论】：

你为什么要从 rest_framework 导入员工
我创建了一个员工类 class employees(models.Model): firstname = models.CharField(max_length=10) lastname = models.CharField(max_length=10) emp_id = models.IntegerField() def __str__ (self): return self.firstname

【解决方案1】：

这是名称冲突。请将您的应用名称更改为 rest_framework 以外的其他名称。
