First thing I notice is that you're not following the Rails default naming conventions. If you have a class TankTicket the table name should be tank_tickets > I Have a form that requires 'tank_id', 'ticket_date', 'batchid', > 'product', 'api', 'tank_temp', and 'gauge' > > I'm calculating the rest of the data in the application helper.

The application helper lives in the View layer of Model-View-Controller (MVC). Data calculation belong in the Model layer. View layer helpers like the application helper can be used for formatting of data for display to the user, but should not directly calculate data that need to be persisted into a data store. Read up on ActiveRecord callbacks for information about where and when to "trigger" your calculations. But, the first thing you need to do is get your calculations out of the View helper and into the Model layer. That might be the TankTicket class in your case, but I don't have enough information to know that for sure. http://railsapi.com/doc/rails-v2.3.8/classes/ActiveRecord/Callbacks.html -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
