Re: how call method from model to controller in rails 3
You are calling list as a class method so you need to define it as a class method def self.list # some stuff end or you need to call it as an instance method s = Sale.new @stamp = s.list or even @stamp = Sale.new.list On 14 October 2011 13:14, Pab <prabu.net88-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, > > i want to know how to use method from model to be used in > controller like > > sale.rb model > > def list > # some stuff > end > > employee controller > > def show > @stamp = Sale.list > end > > > which shows me following error > undefined method `list'' > > how to over come this problem? > > thanks, > -pab > > -- > You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to rubyonrails-talk+unsubscribe@googlegroups.com. > For more options, visit this group at http://groups.google.com/group/rubyonrails-talk?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Now you have the opposite problem... You are now calling list as an instance method and you have it defined as a class method. You need to do ONE of the following. Define it as a class method, and call it as a class method: def self.list code end @list = Sale.list Define it as an instance method and call it as an instance method: def list code end @list = Sale.new.list However, based on what the list method does, it''s probably best that you do the former and have it be a class method. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
