[Rails] Re: simple select
well if you want all the primary photos just use my suggested named_scope. then you can ask: @all_primary_photos = Photo.all.primary # or just Photo.primary @all_galleries = Gallery.all no loop needed. but if you want to loop, you can do that with @all_galleries.each do |gallery| # gallery.photos end On 27 Feb., 15:05, Petan Cert wrote: > Eifion Bedford wrote: > > It looks from your code as if you're returning a list of user galleries > > rather than a single one, so the list you get won't have a photos > > method. > > Does your code work if you change the third line in your method to > > > @gallery = @user.galleries.first > > Yes, thats the error. > Now it is working but just for the first one. > > Is there a way to loop all of the users galleries? > Thank you. > > P. > > -- > Posted viahttp://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Now it is working but just for the first one. Is there a way to loop all of the users galleries? Thank you.

[Rails] Re: simple select
It looks from your code as if you're returning a list of user galleries rather than a single one, so the list you get won't have a photos method. Does your code work if you change the third line in your method to @gallery = @user.galleries.first Eifion http://asciicasts.com Twitter: @eifion On Fri, Feb 27, 2009 at 12:47 PM, Petan Cert < rails-mailing-l...@andreas-s.net> wrote: > > Thx for all your suggestions, but it always ended up with this error. > > NoMethodError in GalleriesController#index > undefined method `photos' for # > > def index > @title = "gallery preview" > @user = User.find(params[:user_id]) > @gallery = @user.galleries > @primary = @gallery.photos.primary.first > end > > I think, that my routes should be fine. > > -- > Posted via http://www.ruby-forum.com/. > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thx for all your suggestions, but it always ended up with this error. NoMethodError in GalleriesController#index undefined method `photos' for # def index @title = "gallery preview" @user = User.find(params[:user_id]) @gallery = @user.galleries @primary = @gallery.photos.primary.first end I think, that my routes should be fine. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: simple select
or you could add a named_scope to your photo-model:
named_scope :primary, :conditions => { :primary => true }
then your call could be like:
@primary_photo = @gallery.photos.primary.first
this should be the nicest alternative.

[Rails] Re: simple select
the correct call is:
@primary_photo = @gallery.photos.find(:first, :conditions => {:primary
=> true})
or (but thats an old one and i don't know if that isn't deprecated):
@primary_photo = @gallery.photos.find_first_by_primary(true)
