I would like to verify a parameter is present before a search is posted.
min_age = params[:min_age]
max_age = params[:max_age]
@users = User.find(:all,
:conditions => ["years >= ? AND years <= ? " min_age,
max_age])
Basically I am just concerned about the max_age.
I tried this:
min_age = params[:min_age]
max_age = params[:max_age]
if max_age.nil?
flash[:notice] = "please enter max age!"
redirect_to :action => "index"
@users = User.find(:all,
:conditions => ["years >= ? AND years <= ? " min_age,
max_age])
But the search still ran with a nil max_age parameter.
