before_action for only one action

Hi there,

If I want a before_action for only one action, like

before_action check_something_with_redirect_if_any, only: :index

Is there another way doing that? Or is this the recommend way?

If not what else could work here?

Thanks, Martin

You can put like this

before_action check_something_with_redirect_if_any, except: [all actions except index]

but its very verbose :smiley:

If you want it for only one action, Jay call it in the action.

I tried it, but I have a view, so interesting that it doesn't work, because they have a redirect_to inside. If I put it in the action, i get the "dont call more than one redirect_to or render" message, which I could fix by using some if statements, but this looks ugly. I think the before_action's will stop if the first gets a redirect_to, so the next will not be run anymore, and this is what I want.
