The key is a string in the format "filer:perm:", i.e. it does not contain the user id. This will be sufficient for most use cases. Patch this method to include the user id in the cache key if necessary, e.g., for far more than 1,000 admin users to make the cached unit require less memory. Parameters: user (UserModel): The user for whom the cache key is being generated. The `user` can be an instance of the default `django.contrib.auth.models.User` or any custom user model specified by `AUTH_USER_MODEL` in the settings. permission (str): The permission for which the cache key is being generated. Returns: str: The generated cache key. z filer:perm:)rrs ;/home/dcms/DCMS/lib/python3.12/site-packages/filer/cache.pyget_folder_perm_cache_keyr s& %%c~tjt||}|r|j|jdSy)a Retrieves the cached folder permissions for a given user and permission.
