Hello all!
In app/models/photo.rb, these Active Record calls:
def previous_photo
self.user.photos.find(:first, :conditions => ['created_at < ?',
created_at], :order => 'created_at DESC')
end
def next_photo
self.user.photos.find(:first, :conditions => ['created_at > ?',
created_at], :order => 'created_at ASC')
end
def previous_in_album
return nil unless self.album
self.user.photos.find(:first, :conditions => ['created_at < ? and
album_id = ?', created_at, self.album.id], :order => 'created_at
DESC')
end
def next_in_album
return nil unless self.album
self.user.photos.find(:first, :conditions => ['created_at > ? and
album_id = ?', created_at, self.album_id], :order => 'created_at ASC')
end
..have their order params clobbered by an preceding 'order by
created_at DESC', which is inserted because of this association in the
user model:
has_many :photos, :order => "created_at desc"
find(:first) is also deprecated. The fix:
def previous_photo
self.user.photos.where('created_at < ?', created_at).first
end
def next_photo
self.user.photos.where('created_at > ?', created_at).last
end
def previous_in_album
return nil unless self.album
self.user.photos.where('created_at < ? and album_id = ?',
created_at, self.album.id).first
end
def next_in_album
return nil unless self.album
self.user.photos.where('created_at > ? and album_id = ?',
created_at, self.album_id).last
end
Onward!
Mike
