Hi All, I'm using file_column_field for uploading the images it's working fine.But it throws random error as shown below. eg., <%= file_column_field("ad","ad_picture")%> I'm using like this,but while uploading or editing the image it throws an error randomly: undefined method : ad_picture_temp for<Ad:#Object> i think this issue is comes while creating the file column temporary(temp) object. It occurs randomly.In single port its working fine,but i configured in multiple port but it throws an error randomly. Can someone please help on this? Thanks in Advance.. Regards, Viswanathan.J
