I am using Ruby on Rails 3.1 and I would like to implement pagination using the WillPaginate gem. In order to keep the business logic in models I would like to know if it’s a common practice to run the paginate method (related to the WillPaginate gem) inside a model.
Is this common practice or not?
No it is not
Pagination calls should not belong in the model because it is strictly related to presentation. The implementation of the pagination could be in the model if you are writing your own pagination logic, but the calls to pagination should be in the controller.
