Hi all,
I have two models gallery and photo (has_many - belongs_to).
Can I use this to find the primary photo for the given gallery?
@gallery = @user.galleries
@primary_photo = @gallery.photos.find_by_primary(true).first
find_by_xxx returns
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)

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.

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
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|
