Redirect to_back

I am seeing some more differences between 1.2.x and 2.3.2 and they just
baffle me.

def some_method
if params[:report][:salesmancode].to_s == ‘’ || !
params[:report][:periodno]
flash[:message] = “You forgot to select an employee or pick a time
period”
redirect_to :back
else
blah, blah
end
render :layout => false
end

and I get a message about not being able to render/direct to more than 1
time. Why doesn’t ‘redirect_to :back’ simply end processing and redirect
the user? Is there some better way of doing this now?

that worked…doesn’t show my flash message so obviously something
changed with flash. I thought it came from session but I can’t find it
in the API.

It is a little confusing but the short answer is don’t count on render
and redirect statements executing immediately. The best fix here is to
put your render :layout => false inside your else clause. That way
there’s no possibility of rendering twice.
