问题 Can anyone show me how to declare an inList constraint within a Grails controller? Let’s say I have this class: class A { List hello } How can I add the inList constraint for the hello List from within the controller? 回答1: Define a constraint in which a List property has values validated against a list of lists?

问题 When passing a multidimensional array to a rails controller, it does not seem to parse correctly. Am I doing it wrong? url: http://localhost:3000/people?sort[][]=lastname&sort[][]=1&sort[][]=firstname&sort[][]=1 params: { "sort" => [ [0] nil, [1] nil, [2] nil, [3] nil ], "action" => "index", "controller" => "people" } should be: params: { "sort" => [ [0] => [ [0] => 'lastname', [1] => 1 ], [1] = > [ [0] => 'firstname', [1] => 1 ] ], "action" => "index", "controller" => "people" } 回答1: Rails

问题 I'm wondering what's the best (per Angular way) of passing data between views that display on particular route and I would like to avoid passing data via URL as there can be a lot of it or would require some sort of conversion to strings etc. All in all not a good idea. An example to understand this: I have a create new content view which displays with empty fields and users are free to enter all the data they want. But in some cases I would like some of these fields to be pre-populated with

问题 I am trying a simple example of an AddressBook Angular application. I have a factory that returns an array of records and it it gets displayed in a list view using a List controller angular.module('abModule', ['ngRoute']) .factory('AddressBook', function() { var address_book = [ { "id": 1, "first_name": "John", "last_name": "Doe", "age": 29 }, { "id": 2, "first_name": "Anna", "last_name": " Smith", "age": 24 }, { "id": 3, "first_name": "Peter", "last_name": " Jones", "age": 39 } ]; alert(

问题 I have 5 separate SQL queries that I am executing in order in a controller action. This is the method I am using to execute them: var entity = new TestEntities(); entity.Database.ExecuteSqlCommand("//SQL Query"); So, basically I have five ExecuteSqlCommand in a row with different queries that must execute in order and the code must continue to execute below them. Is there a better way to execute queries from inside a controller action? I am not sure the best way to do error handling with this

问题 If I wanted to make it so that every url call apart from ones I have defined after act upon /ExplicitControllerName/ExplicitActionToRun ... how might the routing look like. for example some pseudo code: default_pathing: pattern: /{controller}/{action} defaults: { _controller: Bundle:Default:index } So if I went to www.example.com/Page/About it would call my controller class Page extends Controller { public AboutAction() { // Called by above URL } } This question does not answer: Symfony2 /

问题 Given a Spring-MVC controller method: @RequestMapping(value = "/method") public void method(ParamModel params) { /*...*/ } with model class: public class ParamModel { public int param1; } The following two results are as expected/desired: Request with param1=1 : method completes successfully.

If a request is made with an additional parameter (e.g. nonexistentparam=1 ), there is no

问题 I want to create a redirect method that could be called from other methods. Unfortunately, I can't do it as I want (see source below). I propose a solution, but I want to redirect just calling the method, not doing more stuff. My solution: class FooController extends Controller { public function foo(Request $request) { if ($result = $this->__check($request)) { return $result; } return view('foo'); } private function __ckeck(Request $request) { if (doSomething) { return redirect('/'); } return

问题 I am using Ruby on Rails 4 and I would like to properly handle the updating and creating process of associated records through the update_attributes method. That is, I have the following: # Model class Article < ActiveRecord::Base has_many :categories accepts_nested_attributes_for :categories end # Controller class ArticlesController < ApplicationController def update @article = Article.find(params[:id]) @article.update_attributes(update_params) ... end private def update_params params
