controller

问题 In Codeigniter 2.1.2 I want to create base controller and then extends from this controller. It does not work and I have no idea why and I'm pretty desperate now.

In \application\controllers\Home.php I have this: <?php if ( ! defined('BASEPATH')) exit('No direct

问题 Is there any way to soft delete all the existing rows in a table?

问题 I have developed a Single Page App that uses a REST api. Users are required to login to access the application. When a user logs in they are redirected to /dashboard. On this URL / route, I would like to load a different template and controller based on the role of the user (e.g. normal user or admin user). I have looked at https://github.com/angular-ui/ui-router/wiki under the templates section but none of the options support what I am trying to achieve. By using templateUrl and function

问题 I'm trying to make a nested form with form_for and fields_for . After much research and in-success, not working on my project anymore. I'm just trying to recreate a railscast to see what have I done wrong. I'm trying to re-create the example found at http://railscasts.com/episodes/196-nested-model-form-part-1 which shouldn't be that hard since the code is there, but I can't manage to create questions from the survey. Here is my code until now: rails new surveysays rails g scaffold survey name

问题 Think about a simple Rails scaffold application with a "new" action containing a form to add records to a database with a "save" button. After the "create" action the controller redirects to the "show" action, where the user can use the "edit" link to edit the just inserted record. So far, so simple. But if the user instead uses the browser's back button after creating a record to get back to the "new" action, the browser shows the form with the values the user just has entered. Now he

问题 There are some similar posts already here, and tried every solution suggested, and still does not work... I can not get value inside controller, it is always null. Below is the code.

问题 Having the following code: @RequestMapping(value = "/greeting", method = POST, consumes = APPLICATION_JSON_VALUE, produces = APPLICATION_JSON_VALUE) @ResponseBody public String greetingJson(@RequestBody String json) { System.out.println("json = " + json); // TODO json is null... how to retrieve plain json body? return "Hello World!"; } The String json argument is always null despite json being sent in the body. Note that I don't want automatic type conversion, I just want the plain json

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
