Hi Bro.·.

If I understand you, you can this:

def any_func(..., request):
...
     .filter(created_user=request.user)


Cheers Bro.·.

Hi Bro .`.

Thanks for your response, but I need to do that:

If I make these:

Products.object.all()
or
Products.objects.count()

I need to django, auto include a .filter(created_user=request.user) ... today I`m doing exactly you write, but I need to make these filter, one-by-one...

Thanks Jason, 

But, can I get current user on model manager? I need to filter with that info.

What you can do is add a middleware that sets the current user in a thread local variable. That way you can then add a custom model manager that reads that variable.

Then all of your filters will be set automatically.

Thanks Andreas,

Using your tip, I installed django-tools app, and now I can get the current user junt using single line... :)

One question... these locals variable, change for each connection?  example:  I have 1 site, and I want to get several models, with FK for each user.. so.. User1 can only see data from him.. that's the reason I need to filter...  Works like these?

I don't know how django-tools solves it - but it usually is set for every request to the server.

When running django you have 1 or more threads that run the server. Each thread can handle one request at a time - others get queued (you don't usually see this). So when the request is done the middleware should clear the user (that's how I wrote it at least - it's perhaps overkill, but better safe than sorry). The next incoming request will then have a new user - even if it is the same user from the previous one.

Regards,

Andréas
