I'm not sure what is the best approach for my problem. I need a model for notification (or alerts) in my application. Notifications are based on services, have multiple fields to define conditions and are associated with a user. Here's an example for a reddit notification: user_id: 1 type: post_karma condition: above value: 100 And here's a weather notification: user_id: 2 type: temperature city: Seattle condition: above value: 70 So both entries are notifications but they have different fields. Should I: - Create different models for each type of notification? - Create a base notification model and other models for each type that extend the base one? - Only have 1 model (notification) and then some sort of condition table. A notification has multiple conditions. Thanks. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
