I'm working on a webapp where users can login to see their online wine cellar.
I've got the Django REST models setup, as well as the front-end design in Angular but I'm having trouble putting the pieces together and my main issue is for user authentication.
I've read many posts on here and various tutorials but I can't seem to find a step by step method to implement authentication:
From what I understand Angular makes a POST request on a url where DRF verifies that username and password match and returns a token or other auth proof.
I feel like I'm close but I need a more general view of how this works to put the pieces together.
Thanks in advance
JSON Web Token Authentication Unlike the built-in TokenAuthentication scheme, JWT Authentication doesn't need to use a database to validate a token. A package for JWT authentication is djangorestframework-simplejwt which provides some features as well as a pluggable token blacklist app.
Authentication is a mechanism that provides access control based on the credentials associated with incoming requests. Django REST Framework provides several authentication schemes.
I imagine there are a lot of ways to do this, let me explain what I do, hopefully it is helpful. This is going to be a long post. I would love to hear how others do this, or better ways of implementing the same approach. You can also check out my seed project on Github, Angular-Django-Seed.
I use token authentication with Witold Szczerba's http-auth-interceptor. The beauty of his approach is that whenever a request is sent from your site without proper credentials, you are redirected to the login screen, but your request is queued to be re-fired on login complete.
Here is a login directive used with the login form. It posts to Django's auth token endpoint, sets a cookie with the response token, sets the default header with the token so all requests will be authenticated, and fires the http-auth-interceptor login event.
.directive('login', function ($http, $cookieStore, authService) { return { restrict: 'A', link: function (scope, elem, attrs) { elem.bind('submit', function () { var user_data = { "username": scope.username, "password": scope.password, }; $http.post(constants.serverAddress + "api-token-auth", user_data, {"Authorization": ""}) .success(function(response) { $cookieStore.put('djangotoken', response.token); $http.defaults.headers.common['Authorization'] = 'Token ' + response.token; authService.loginConfirmed(); }); }); } }
})
I use the module .run method to set check for the cookie when a user comes to the site, if they have the cookie set I set the default authorization.
.run(function($rootScope) { $rootScope.$broadcast('event:initial-auth'); })
Here is my interceptor directive that handles the authService broadcasts. If login is required, I hide everything and show the login form. Otherwise hide the login form and show everything else.
.directive('authApplication', function ($cookieStore, $http) { return { restrict: 'A', link: function (scope, elem, attrs) { var login = elem.find('#login-holder'); var main = elem.find('#main'); scope.$on('event:auth-loginRequired', function () { main.hide(); login.slideDown('fast'); }); scope.$on('event:auth-loginConfirmed', function () { main.show(); login.slideUp('fast'); }); scope.$on('event:initial-auth', function () { if ($cookieStore.get('djangotoken')) { $http.defaults.headers.common['Authorization'] = 'Token ' + $cookieStore.get('djangotoken'); } else { login.slideDown('fast'); main.hide(); } }); } } })
To use it all my html was basically like this.
<body auth-application> <div id="login-holder"> ... login form </div> <div id="main"> ... ng-view, or the bulk of your html </div>

We've tried to solve most common Django auth/registration related things from a backend and angular perspective in these two libraries.
