The one place I've used a <? block so far is to compute the value of a complex display-logic variable (a count depending on multiple conditions). The controller doesn't, and shouldn't need to, care about the count that the display logic needs, it is just concerned with passing in the correct data structure for display. The count is required only because of the arguably weird way that html table rowspans work. Display logic only. Adding the "extra data" in the controller would make the controller code, and the data structure passed to the template, uglier, and would tie it into the display logic in a way that _breaks_ the MVC separation. The alternative of computing the value every time I need it would make my template much uglier and harder to maintain. Unless there's some Kid trick I don't know for setting the value of a variable? --David --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
