proper rails mvc design: question about where to put certain logic

hi there!

ok heres my problem: i have a box where i want to display upcoming radio shows. the one which is currently running plus the n next ones. so there should be a call to render a (or 2) templates in my main layout which gets includet in various controllers.

since there is no method of the controller available in the layout i have to place the logic somewhere else.

i see 1.5 possibilities: a) components (thats the 0.5, we'll forget about this right here since it will be depreciated soon anyway)

b) make 1 or 2 static functions in the model

but im quite sure there is another solution to this problem? is there a more elegant way to do this?

thanks!
