问题 Rather than displaying a PNG in the browser window, I'd like the action result to trigger the file download dialogue box (you know the open, save as, etc). I can get this to work with the code below using an unknown content type, but the user then has to type in .png at the end of the file name. How can I accomplish this behavior without forcing the user to type in the file extension? public ActionResult DownloadAdTemplate(string pathCode) { var imgPath = Server.MapPath(service

问题 Im wondering if there is a way to pass an argument to a directive?

问题 I'm looking for the best method for the following issue I have. I current have a large number of objects that all inherit for a single base object and are all very similar. Is there a solution available the will allow one create action and one edit action without needing to replicate a lot of the same code. So for example I might have a person object: public class PersonBase { public string FirstName { get; set; } public string LastName { get; set; } } And then I will have a number of objects

问题 I am using Ruby on Rails 3 and I am trying to set an helper_method that should work just for a controller (example: AccountsController) and for all views related to that, also when its views are rendered in another views not related to that controller. I take inspiration from the Railcast "Restricting Access".
