'WSGIRequest' 对象在 django-cartridge 中没有属性 'cart'

Question

我正在使用 Django 1.10，Mezzanine 4.4.2，在安装 Mezzanine 后手动安装 Cartridge。现在我可以通过墨盒添加产品和价格。但是，当我点击“购买”按钮时，出现以下错误：-

AttributeError at /shop/product/nike-blue/
'WSGIRequest' object has no attribute 'cart'
Request Method: POST
Request URL:    http://localhost:8000/shop/product/nike-blue/
Django Version: 1.10.3
Exception Type: AttributeError
Exception Value:    
'WSGIRequest' object has no attribute 'cart'
Exception Location: G:\Py_Envs\Racknole\Mezzanine_Trial\lib\site-packages\cartridge\shop\views.py in product, line 69
Python Executable:  G:\Py_Envs\Racknole\Mezzanine_Trial\Scripts\python.exe

此外，如果我点击结帐选项，它会显示一个空购物车，然后当我再次点击继续购物时，它会将我重定向到我想要更改的 http://localhost:8000/shop/。

提前致谢。

Answer 1

此问题是由于缺少 Cartridge 的 ShopMiddleware。将此添加到您的 settings.py 文件中：

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    .......,
    .......,
    'cartridge.shop.middleware.ShopMiddleware',
)

如果问题进一步存在，则将您的 settings.py 文件与 This link.
