Multiple views of the same model

Hi,

How can I implement two different views on the same model? My model has 30 attributes. The First view should display 1-12 and the second view the rest of them.

In my case I am dealing with two medical anamneses with different topics. My idea was to generate a model called anamnesis with every field name of the two topics. This model should be split into two views.

You could use a parameter in the url for the show action to indicate which view you want, then in the show action test the parameter and render the appropriate view. You could use a separate action in the controller. You could use a separate controller for the second view. If one view is showing some attributes and another only the rest (not clear from your post whether the second view shows all of them or not), then consider whether it should be a separate model.

Have a look at Florian Hanke's Representer plugin:

http://github.com/floere/representer

It allows you to have 'object oriented' views, maybe it suits your needs...

Thanks for the suggestions. I will try it.

It sounds like you're reinventing single-table inheritance here. Why not just use Rails' single-table inheritance features?

Better yet, don't try to put two classes in one table. Single-table inheritance works, but is problematic since it doesn't really fit the relational model. Start with it, but consider refactoring to multiple-table inheritance.
