Re: error of "undefined method `each'' for #<Picture:0x927dea0>"
you exectued people.all.first so the @user only has one picture object instead of an array of pictures 2011/6/10 joanne <joanne0558-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>> hi all, > > I have an error "undefined method `each'' for #<Picture:0x927dea0>" > what is that mean? > > in my view > [code] > > <% @user.each do |p| %> > <%= p.image %> > <% end %> > > [/code] > > > in controller > [code] > @user=picture.all( > :joins => :culture, > :conditions => (Album.joins(:description))).first > > [/code] > > > plz give me some advance > > -- > 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-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > 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.

Re: error of "undefined method `each'' for #<Picture:0x927dea0>"
Simple. You get only one picture object (the first one) because you''re using .first method. Since you have only one object, you can''t iterate over it using the each loop. Get it? Just use @user.image instead in the view :) On Fri, Jun 10, 2011 at 9:46 AM, joanne <joanne0558-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> hi all, > > I have an error "undefined method `each'' for #<Picture:0x927dea0>" > what is that mean? > > in my view > [code] > > <% @user.each do |p| %> > <%= p.image %> > <% end %> > > [/code] > > > in controller > [code] > @user=picture.all( > :joins => :culture, > :conditions => (Album.joins(:description))).first > > [/code] > > > plz give me some advance > > -- > 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-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > 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.
