Hi there, I'd be happy if someone can help me with the following: The application is for uploading all kinds of datafiles which should be displayed accordingly to their mimetypes.
This is the class/database hierarchy of what I want to archive: Class:Filegroup has_many :binary Attributes are e.g. groupname, timestamps of upload/update and so on Class:Binary This is the generall description of the uploaded file Attributes included are e.g. original_filename, mimetype and so on If someone is uploading a file with a known mimetype, a (sub-)class should be created with specific details about the file e.g. Class:Image Including width, height... Class:Text Textstyle (php, xml)... I'd like to access the list of *all* files through something like: Filegroup.find(xxx).files iterates over it and render it automatically as it is specified in each of those sub-classes (so images whould be a thumbnail, text is shown fully and binary just a simple download link) I found the Polymorphic-attribute for the database associations but this is the other way round, isn't it? Also I took a look at http://archive.robwilkerson.org/2009/08/26/learning-ruby-on-rails-file-upload/index.html but this isn't exactly what I need because the class which should be used should be defined automatically. (E.g. somewhere is specified which class should be used for which mimetype) Thank you for your time and help. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
