I had originally used what you suggested. And this was the response:
ERXKeyFilter filter =
ERXKeyFilter.filterWithAttributesAndToOneRelationships();
filter.include(FoodFamily.MAIN_IMAGE);gives: <foodFamily type="FoodFamily" id="1"/> When I did what I did I get this response (all notice that it says ERDatabaseAttachment, this is wrong it is a File): <foodFamily type="FoodFamily" id="1"> <mainImage type="ERDatabaseAttachment" id="1"> <available>true</available> <configurationName nil="true"/> <creationDate>2011-11-09T01:32:39Z</creationDate> <height nil="true"/> <mimeType>image/jpeg</mimeType> <originalFileName>tomato.jpg</originalFileName> <ownerID nil="true"/> <proxied>true</proxied> <size>4951</size> <smallData nil="true"/> <storageType>db</storageType> <thumbnail nil="true"/> <webPath>/1.jpg</webPath> <width nil="true"/> <attachmentData type="ERAttachmentData" id="1"/> <parentAttachment nil="true"/> </mainImage> </foodFamily> Regards James On Dec 13, 2011, at 1:08 PM, Farrukh Ijaz wrote: > Hi James, > > The filter is passed to response object in ERRest framework, and that filter > is applied to the object.
