Use auxillary functions. Model fields carry no implicit "display" concept with them, since they represent the data object, separate from the presentation. > > For example if I have a model called Course with fields n_girls and > n_students, > > if for a particular record n_girls = 4 and n_students = 10, I want to > display for n_girls: "40% (4)" instead of just "4". > > Obviously I can do this in the template but there are multiple fields > I want to customize and the lack of switch/elsif statement in the > templates would make for a deeply nested structure so I'd rather do it > upstream in the model. Write some model methods that return the appropriate string format of the given field. Or write some filters that accept a model object as the input value and format it appropriately. Using template filters for presentation changes always feels pretty natural to me. Model methods work, but, as noted above, my inclination is always to use models as the presentation-agnostic data object and set things up so that I can control presentation indepedently of the data itself.
