Setting a variable only one time

Rails
1

In my application_controller I have:

before_filter :set_default_role

layout :specify_layout

private
def specify_layout
if @current_role == :intra_guest
“intranet”
elsif @current_role == :inter_guest
“internet”
else
#(devise_controller? || user_signed_in?)
“application”
end
end

def set_default_role
if request.path == “/intraOp”
@current_role = :intra_guest
elsif request.path == “/interOp”
@current_role = :inter_guest
else
@current_role = current_user.try(:role)
end
end

When I call http://mysite/intraOp…@current_role is set to
:intra_guest but if I click to a link, say http://mysite/other, the
@current_role in not :intra_guest anymore because the path is not
/intraOp and before_filter is run every time before an action.
I think the solution is to run set_default_role only one at
application start and not before every controller action.
Advices?

If you always want it :intra_guest then why have you got the logic in
set_default_role why not just set it to that?

You say that you want to set it once at application start, remember
that the application will server multiple users one after the other
without restarting, so all users would get the same value.

If you are trying to do it based on which url a user goes to first
then save the value in the session for later use by that user.

The user may or not login to the application, if the user wants to
manage the application then it must be logged in and a role is
assigned, say admin, if it wants only see a list of products, for
example, then it must not to be logged in and I assign a default role,
say guest.

So how could you set it once at application start when you need
different values for different users? Application Start is when the
server is started. It may not be restarted for months. There is not
one instance of the application for each user.
