Laravel 4缓存：会忘记一个关键只影响单个用户或所有用户吗？

Question

Suppose I cached an Eloquent list query like this:

Article::with('comments')->remember(5, 'article_comments')->get();

When I update/delete that model, obviously I have to Cache::forget('article_comments') to generate/update a new list.

Now, in my app design, those update/delete only happens for a single user, so i was hoping the Cache::forget('article_comments') only forgets the current user's query list, not all users' in entire network.

So, my question is, will Cache::forget() deletes entire cache for all users, or only the cache in current user's computer?

Answer 1

It will delete it for everyone. If you want to cache something for a specific user then the key will need to be unique for that user. Usually this is done by naming the key something like article_comments_1, where 1 is the users ID.
