在Django 1.9中訪問模型緩存

Question

Django1.9緩存可以通過from django.core.cache import cache訪問。 但是怎樣才能訪問模型緩存？

此代碼在以前的版本中工作。

from django.db.models.loading import cache 
from django.db import models 


def get_custom_car_model(car_model_definition): 
    """ Create a custom (dynamic) model class based on the given definition. 
    """ 
    # What's the name of your app? 
    _app_label = 'myapp' 

    # you need to come up with a unique table name 
    _db_table = 'dynamic_car_%d' % car_model_definition.pk 

    # you need to come up with a unique model name (used in model caching) 
    _model_name = "DynamicCar%d" % car_model_definition.pk 

    # Remove any exist model definition from Django's cache 
    try: 
    del cache.app_models[_app_label][_model_name.lower()] 
    except KeyError: 
    pass 
... 

現在該如何處理？我想刪除模型緩存

我收到錯誤

'LocMemCache' object has no attribute app_models

嗨，也許一個try /除了這種方式，您可以爲早期版本的Access高速緩存，並保持支持

try: 
    from django.apps import apps as cache 
except ImportError: 
    from django.db.models.loading import cache
