Topic: Load session variable at startup
I have a bunch of actions that require session[:season] to be set. Since I can't guarantee a user will enter the site at a given point, I'm using this line for multiple actions:
@season = session[:season] || load_season
... where load_season uses the current session[:season] if it's not set or otherwise pulls it from the database.
This isn't awfully bad, but it's not very DRY, since I have to repeat this line for many actions. I also have to create @season instead of directly referencing session[:season].
In PHP, I would have just set the session var in an early line of code which would guarantee that it was set.
Is there any equivalent in Rails -- a location that says "do this code before doing anything else"?
