Are session aware Models a bad thing?
- by kevtufc
I'm thinking specifically in Rails here, but I suspect this is a wider question.
In a Rails web application I'm using data from the session in models in order that the models know who is logged in. I use this in a method which filters out some data from the database depending on a very simple permissions system.
The thing is: using sessions in models in Rails requires a bit of a workaround. It works, but I've a feeling that it's something that I shouldn't be doing and I'm worried there's a big gotcha I'm missing.
I suppose the Right Thing To Do would be to return all the data and filter out the not-wanted bits in the controller before passing that to the view, but doing it in the model seems to avoid quite a bit of code duplication and so feels "cleaner."
Can anyone tell me why or shouldn't do this? Or that it's not a problem?
