mean-stack

问题 I am working on a mean stack application using angular material design. I got stuck on using 'md-datepicker'. I was designing a form which is having an Date of birth field but md-datepicker dont allow to select the year. I found a bower packer "https://github.com/alenaksu/mdPickers" and I was trying to add it into my project. I installed the bower npm install bower Install package, bower install mdpackages after this steps I got the bower-components in my project directory. So my question is

问题 There are lots of discussion and favor that token based architecture of authentication of MEAN application is secure. But I have question that is it really pass user-name and password for authorization and authentication as payload in JSON Web Token, and if we are not passing secured information in payload then how JSON Web Token authenticate user without user-name / password in server side. I read lots of architecture stuff but they can't explain that what logic they used to authenticate

问题 I am currently new to use MEAN stack with the following packages: https://github.com/linnovate/mean. However, after I had created the project and found that Jade is their default template engine.

问题 I have my Mean stack delete functioning properly; however, I can't seem to figure out how to update the view with the updated JSON once deleted. My express server side logic: .delete(function(req, res) { Service.remove({ _id: req.params._id }, function(err, service) { if (err) res.send(err); res.json({ message: 'Successfully deleted' }); }); }); My angular controller $scope.removeItem = function(id) { $http.delete('/api/hc/' + id) .success(function(data) { $scope.services = data; console.log

问题 Before you say anything, I know the solution probably is to inject the dependency but I checked other open source codes and compare it with mine, it is exactly the same. While theirs work while mine's not working Currently the problem is at route '/signup' I got Error: error:unpr Unknown Provider when I check the console at route '/signup' and Whenever I go to '/signup' route and press submit button it supposed to hit the api and redirect to '/' but what I got instead is Cannot POST /signup.

问题 I am trying to make a MEAN CRUD app. I am not exactly sure which of my routes are off, but i cannot seem to communicate with the mongodb to display data. The debugger seems to break when "rug-list.component.ts" calls the getRugs() service in "rug.service.ts". (I am also wondering: do the pathnames in the back-end files need to match those of the front-end?) Any advice would be much appreciated. :) » rug.service.ts (frontend) ... @Injectable({ providedIn: "root" }) export class RugService {

问题 I have a record in such a way like below 1) { "name":"A", "parents":[ADMIN], "childrens":[B,C,D] } 2) { "name":"B", "parents":[A], "childrens":[D,K,L] } 3) { "name":"C", "parents":[B], "childrens":[K,L] } 4) { "name":"D", "parents":[C], "childrens":[L] } Here if a add a new record 'E' and will make 'C' as parent ,then the logic is the record 'E' should be added as child to the parent of 'C'i.e for 'B' and at the same time 'E' should also be added to parent of 'B'.This logic is quite confusing

问题 I'm having a problem using the Angular2 router and express, but none of the previous questions seem to have the solution I need. I'm using the latest version of the angular2-cli. When I direct my browser to localhost:3000, I get the generic "app works" message that the angular2-cli generates. My problem arises when I try to navigate to one of my child routes, such as localhost:3000/auth/login - it redirects me back to the same "app works" page, instead of showing me a page that says "login

问题 One of the things that different Angular learning materials seem to be doing differently is passing variables. What is the difference between using $scope or the "someCtrl as some" syntax? What are the advantages? Should I stick with always using one of them or there are certain scenarios when using one of them is better than the other? 回答1: Todd Motto has some very good articles on this! Digging into Angular’s “Controller as” syntax A better way to $scope, angular.extend, no more “vm = this”
