Developing code that can go multiple places

Rails
1

In my controller code, depending on the values in the database, I may
want my user to go one of several places. But when I put more than one
redirect in, it gives me the message:

Render and/or redirect were called multiple times in this action.

How do I do this?

redirect_to(some_place) and return

Alternatively, store the desired destination URL and redirect once at
the end of the method.

stored_location = nil

…

stored_location = ‘fall_down_go_boom_url’ if some_criteria

…

redirect_to stored_location unless stored_location.nil?

Hi,

Maybe s.ross’s explanation is enough, but just in case, I had to deal
with the same problem a while back and this might be useful…

redirect_to doesn’t stop the rest of the code in your method/action
from keeping executing so if you use it and then later on in your code
there is another render/redirect_to like, for example, as a default
action after an if/select then there is your problem.

The solution is to use return right after you redirect_to line:

redirect_to
return # here the code leaves the method/action

I hope this helps.
