hierarchy

问题 I'm a little stuck and unable to find the answer to this. In my app test I've created two Entities User and Comment both are mapped correctly. I have created a small controller which depending on the user will add the comment and the data to the ACL tables, if I create my comment as a standard user with the associated for of 'ROLE_USER', and Try to access it as user with the role 'ROLE_ADMIN' I get access denied, it seems to completely ignore the security.yml hierarchy. I know this works by

问题 I'm used to JUnit, in JUnit it is possible to group several tests (usually related to a class) just by defining these tests in a single file (class) and annotating them with @Test . Then, to run several of these tests, a TestSuite is created with @Suite.SuiteClasses and so on. In specs2 it is possible to group several tests at two different levels extending some Specification . For example: "Whatever" should { "do its job when possible" in { whatever(new Thing).work must beSome } "return none

问题 I'm new to mongodb. Let's say I have a "file system" hierarchy in my database: db.directories.save({ _id: "root", directories: ["src", "lib"], files: ["config.cfg"] }) db.directories.save({ _id: "src", directories: [], files: ["file1.js", "file2.js"] }) db.directories.save({ _id: "lib", directories: [], files: [] }) db.files.save({ _id: "config.cfg", size: 2310 }) db.files.save({ _id: "file1.js", size: 5039 }) db.files.save({ _id: "file2.js", size: 1299 }) How would I get the total size of a

问题 I'm already familiar with Linq but have little understanding of extension methods I'm hoping someone can help me out. So I have this hierarchical collection pseudo code ie: class Product prop name prop type prop id prop List<Product> children And I have a list of products List products. Is there any way I can look for product in this collection by the id with a extension method ? In other words I need one item somewhere within the hierarchy. 回答1: Here is a generic solution that will short

问题 I'm trying to generate an n-level hierarchical unordered list with anugularJS, and have been able to successfully do so. But now, I'm having scope issues between the directive and controller. I need to change a scope property of the parent from within a function called via ng-click in the directive template. See http://jsfiddle.net/ahonaker/ADukg/2046/ - here's the JS var app = angular.module('myApp', []); //myApp.directive('myDirective', function() {}); //myApp.factory('myService', function(

问题 I am having trouble creating a tree hierarchy in Python 3. I'd like to be able to do this without using classes. The data I need to start with is not in order and in the format ['ID','Parent'] : data=[['E1', 'C1'],['C1', 'P1'],['P1', 'R1'],['E2', 'C2'],['C2', 'P2'],['P2', 'R1'],['C3', 'P2'],['E3', 'C4'],['C4', 'P3'], ['P3', 'R2'],['C5', 'P3'],['E4', 'C6'],['C6', 'P4'], ['P4', 'R2'],['E5', 'C7'],['C7', 'P5'],['P5', 'R3'],['E6', 'C9'],['C9', 'P6'],['P6', 'R3'], ['C8', 'P6'],['E7', 'C10'],['C10'

问题 I added in parent::__construct(); to the constructors of table and bookmark in order to get this code to work. Why are they not called automatically? If I create an object of type bookmark $obj_ref_bo = new bookmark(); should not bookmark also create objects from each of its parent classes (besides abstract classes). The call chain is bookmark->table->database(abstract)->single_connect /*single_connect*/ class single_connect { protected static $_db_pointer = NULL; private function __construct

问题 Assuming that we have a set of categories: categories={A,B}. Let's assume more that A consists of subcategories: {A1,A2,A3} and B consists of subcategories: {B1,B2}.In addition, there are even more subcategories as follows: for A1:{A1a,A1b}, for A2:{A2a,A2b}, for A3:{A3a,A3b,A3c}, for B1:{B1a,B1b,B1c}, for B2:{B2a,B2b}. How can I build an hierarchical structure in java? Since the cardinality of each set is fixed and known in advance, my initial approach is to use enum types instead of

问题 Suppose I have a big program that consists of hundreds of methods in it. And according to the nature of input the program flow is getting changed. Think I want to make a change to the original flow. And it is big hassle to find call hierarchy/ references and understand the flow. Do I have any solution for this within Eclipse? Or a plugin? As an example, I just need a Log of method names that is in order of time. Then I don't need to worry about the methods that are not relevant with my "given
