My heroku app is tripping over code at the point where i try to do a
count on an empty array. But in development on my local machine with
the very same database and code (taps db:pull) it doesnt trip up.
can anyone tell me why this is? im using ruby 1.8.7 and rails 2.3.2
below is the offending line which produces the error NoMethodError
(undefined method `count' for []:Array):
@recently_checked_sentences_count =
@user.checked_sentences_since_last_login.count
with method below
def checked_sentences_since_last_login()
self.sentences.checked.find(:all, :conditions => ["checked_at
> ?", last_login_at])
end
which uses named_scope
named_scope :checked, lambda{|limit| { :limit => limit, :order =>
"checked_at DESC", :conditions => "checked_at IS NOT NULL" } }
