Python Django REST框架错误-未定义名称

我有一个Django 2.2，它有两个应用程序-状态和更新：

django_api | 地位 | 应用程序编程接口 | 更新

在django_api/url.py中：

    json_example_view, 
    JsonCBV,

 urlpatterns = [

在django_api/status/api/views.py中：

在django_api/status/api/serializers.py中：

from rest_framework import serializers
from django import forms
from status.models import Status

class StatusSerializer(serializers.ModelSerializer):
     class Meta: 
         model = Status
         fields = [
            'user',

            'image']

     def validate_content(self, value):

             raise serializers.ValidationError("content or image is required.")
        return data

from django.contrib import admin
from django.urls import path

from .views import StatusAPIView, StatusCreateAPIView


 urlpatterns = [
    path('/', StatusAPIView.as_view()),
    path('create/', StatusCreateAPIView.as_view()),
    ]

运行python manage.py runserver时，出现一个错误：

File "...\status\api\views.py", line 26, in StatusAPIView
serializer_class = StatusSeralizer
NameError: name 'StatusSeralizer' is not defined

已更新：如前所述，这是一个拼写错误。但是，在我导入status和从status.api导入URL后，出现以下错误：

...\urls.py", line 39, in <module>
path('api/status/', status.api.urls),
...File "C:\Users\fbagi\AppData\Roaming\Python\Python37\site- 
packages\django\urls\conf.py", line 73, in _path
raise TypeError('view must be a callable or a list/tuple in the case of 
include().')
TypeError: view must be a callable or a list/tuple in the case of 
include().

为什么会出现此错误？

这是一个打字错误：

---

您正在调用：StatusSerializer，但它是：StatusSerializer

我在您的视图文件中没有看到StatusCreateAPIView。你创建了这个视图吗？

---

尝试注释或删除

path（'create/'，StatusCreateAPIView.as_view（）），

，看看是否仍有错误。

修复了它，但我发现了一个新错误：NameError:name“status”未定义。查看更新的问题。您是否尝试将

导入状态

添加到URL.py中？@kamilyrb收到一个新错误：“…\url.py”，第38行，路径（'api/status/'，status.api.url），AttributeError:module'status.api'没有属性'url'“您的状态模块中有

urls.py

文件吗？它位于status/api/urls.py下。当我导入它时，我得到了一个新的错误：TypeError:view必须是可调用的，或者是include（）的列表/元组。好的，我发现了问题。如果要添加其他应用程序的URL，则必须使用类似这样的包含函数：

path（'api/status'，include（'status.api.url'））

请尝试ir
