I am new to Datamapper, so please go easy... Using DM in Sinatra I have two models, Album and Photo; Photo has a file attached via paperclip:
class Photo include DataMapper::Resource include Paperclip::Resource property :id, Serial property :title, String property :created_at, DateTime property :updated_at, DateTime has_attached_file :data, url: "/:attachment/:id/:style/:basename.:extension", path: "#{APP_ROOT}/public/:attachment/:id/:style/:basename.:extension" belongs_to :album end class Album include DataMapper::Resource property :id, Serial property :name, String property :created_at, DateTime property :updated_at, DateTime has n, :photos before :destroy do photos.destroy end end In my delete '/albums/:id' route: delete '/albums/:id' do a = Album.get params[:id] if a.destroy redirect '/' else logger.info a.errors.inspect redirect '/' end end The errors show that there are validation errors, but there are no errors present: INFO -- : #<DataMapper::Validations::ValidationErrors:0x13740dc @resource=#<Album @id=2 @name="Quaver" @created_at=#<DateTime: 2013-02-07T10:30:36+00:00 (5895194251/2400,0/1,2299161)> @updated_at=#<DateTime: 2013-02-07T10:30:36+00:00 (5895194251/2400,0/1,2299161)>>, @errors={}> I can force the destroy with the bang method, but then it doesn't call the before :destroy hook in Album to delete the photos. I have not set up any validations in my Models, and am truly baffled. Can anybody shed light on why I am getting ValidationErrors?
