AttributeError：'module'对象没有属性'Bussiness'

Question

这是/app03/views.py：

from django.db import models

def business(request):
    v = models.Bussiness.objects.all()   # this is the line10
    # QuerySet
    # [obj(id, caption, code), obj,obj...]
    return render(request, '/app03/business.html', {'v':v})

这是我的PyCharm CE中的追溯信息：

Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/Django-1.11.2-py2.7.egg/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)
  File "/Library/Python/2.7/site-packages/Django-1.11.2-py2.7.egg/django/core/handlers/base.py", line 187, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "/Library/Python/2.7/site-packages/Django-1.11.2-py2.7.egg/django/core/handlers/base.py", line 185, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
  File "/Users/luowensheng/Desktop/TestIOS/TestPython/pyProject/app03/views.py", line 10, in business
    v = models.Bussiness.objects.all()
AttributeError: 'module' object has no attribute 'Bussiness'
[14/Aug/2017 09:27:27] "GET /app03/business/ HTTP/1.1" 500 64817

在我的/app03/models.py：

中

class Bussiness(models.Model):
    caption = models.CharField(max_length=32)
    code = models.CharField(max_length=32, default='SA')

并且，我已完成此操作：

python manage.py makemigrations
python manage.py migrate 

并在db.sqlite3中生成了app03_bussiness表：

为什么没有属性'Bussiness'？

Answer 1

您应该直接从您的应用模型导入该类。您目前与Django的models模块存在冲突，该模块与您的应用中具有相同名称models：

from django.db import models
from app03.models import Bussiness

def business(request):
    v = Bussiness.objects.all()   # this is the line10
    # QuerySet
    # [obj(id, caption, code), obj,obj...]
    return render(request, '/app03/business.html', {'v':v})
