django rest-auth Facebook registration - django

I am trying to register users via Facebook using django rest-auth.
As per the installation docs here, a rest call to register a user via facebook requires an "access token" and "code". I know what an access token is, but what is "code"?

First of all, you need to create a Facebook Application in the developers page. You will get a Facebook app code and a secret.
For using the /rest-auth/facebook/ method from the django-rest-auth, you need to send the access code (obtained using the javascript SDK) and the code of the Facebook Application.
Finally, before using this method, you have to go the the application back-office and create a social application, using the Facebook app code and the secret.

Access profile pictures using Facebook's Graph API v2.3 without user login

Direct access to profile pictures via the Facebook graph API has recently stopped working and appears deprecated. Apparently, this now requires an access token (which requires the user to login to FB first)...
https://graph.facebook.com/{user-id}/picture?redirect=false&type=large
I'm developing a web application in JavaScript, unrelated to Facebook. I would like to offer users the option to use their FB profile picture for posts. They provide their numeric user-id which I save on our server. Until recently, my client app could use the numeric user-id in the above URL to produce a JSON response with a link to the user's profile picture.
Is there an alternative approach to getting a user's profile picture without first requiring the user to login to FB to get a client-side access token?
If They (the users) provide their numeric user-id means that you're using Facebook Login, and they at least gave their public_profile permission to your app, you can just add the App Access Token to the request and it should work.
https://graph.facebook.com/{user-id}/picture?redirect=false&type=large&access_token={app_access_token}
If you don't use Facebook Login, I see no chance to be honest.

Authenticate Facebook users in Cakephp 3x

I have used PHP SDK-4 for Facebook login in CakePHP 3 (beta version) which works fine.Now, I'm in need to fetch user data based on FB login and authenticate users. Am trying with Cake's Auth component. Initially, while trying to Auth users,
$this->Auth->setUser($user)
Got Error: Session was already started as we require session_start() for Facebook login. 1- Tried with enter link description here, and sessions [session_write_close()] etc..still it did not work. Could I get some shot on best way to authenticate users with Facebook login in site?
CakePHPs sessions are lazy started, that is, they are being started once your try to access the session in some way, and in case the session was started manually in beforehand, you'll receive that error, see Session::start().
You can easily workaround this by manually starting the session via CakePHP. The session object is available in the current request, so for example in your controller before using the SDK you could simply do something like
$this->request->session()->start();
and then the Facebook SDK should be able to pick it up.
As burzum already mentioned in the comments, the authentication should better be wrapped up in an authentication handler.
I would suggest having a look at HybridAuth, there's also a CakePHP plugin for seamless integration into CakePHPs auth mechanism, this might give you some ideas for a custom implemenation in case you need to use the v4 SDK, which isn't yet supported by HybridAuth.

How to read Facebook Insights for a Native/Desktop app programmatically

Unfortunately I'm struggling to understand the documentation provided by Facebook.
This is the scenario:
- Some of my iPhone Apps are also registered as Native/Desktop Apps on Facebook in order to support the Facebook Audience Network.
- I'm building a tool in python which will retrieve data from the reporting API in order to run some automated analysis on specific metrics (request, impressions and so on).
The question is: how do I retrieve this data?
The documentation for the reporting API is here: Reporting API
However I'm struggling with the access token.
It says that I could use the specific App Token available here: App Tokens
However by using such token, I get an error saying that app tokens can't be used for Desktop/Native Ads.
What is the correct way to do it then? Here is where I struggle to understand Facebook Documentation.
My guess is that I should use a User Access Token instead, generated for a user that is also the admin of the App for which I want to retrieve the insights.
What really freaks me out is that apparently, this can't be done with normal HTTP calls only but it requires instead to go through the Facebook Login Dialog. I also need to create another Facebook (web) app because there is no way to get a simple "User Object"... Everything needs to start and go through a registered Facebook App. And there's no way to go through these steps by using backend code only.
So... to recap... in order to read the Insights for a Native/Desktop Facebook App (APP_A), I have to:
- Create a new Web Facebook App (APP_B)
- Create a web interface somewhere for APP_B) which will trigger the Facebook Login Dialog and request the read_insights permission.
- Login through this web interface and generate a User Access Token
- Put this User Access Token in my backend code and run the scripts that retrieve the data provided by the Reporting API for APP_B
Really... to me... it doesn't make any sense to create a new Facebook App in order to access the data of another Facebook App.
Isn't there another better, simpler, quicker, cleaner way to achieve the same final result?

Connect facebook phonegap login with django allauth

I'm building up an app that should allow the user to sign up / sign in with Facebook and then he should be able to login (always via Facebook) to the "main" website
To be honest it's a bit more complicated than this. That's because I'm using django-tastypie and django-allauth in the main website to allow sign up, login, and browsing of our API
Basically I want to make the mobile app user browse the tastypie API (accessible only if logged and if you're an user in the main website) and grant him the rights to add rows (like orders)
Here's what I have
A phonegap app with a working Facebook login (I'm working on that right now)
A website with django-allauth and django-tastypie that makes me register as a new user using the allauth's Facebook login
No trace on the main website if the mobile user is doing a sign up via Facebook (this is the problem)
I'm basically confused how I should work with access tokens and how to pass further parameters (I don't need only the Facebook infos to complete the registration, but some custom fields too)
Anyone got experiences on this or would like to expose his workflow?
One common way of doing things is to leave all registration related functionality up to the website. In your phonegap app you can simply point the user to /accounts/login/ using the In-App-Browser (IAB). The IAB has events like loadstart and exit that you should monitor. A simple way of monitoring whether or not the user is successfully logged in is to have him redirected to a specific url, say /accounts/login/complete/, at the end of the login. If you attach a token to that return url (as in /accounts/login/complete/?token=123) you will be able to parse that token in your app. You could simply use the session ID as a token.
A more secure way is to use the django-oauth2-provider app and actually implement a proper oauth handshake. Handling that is almost the same. Using IAB open /oauth/authenticate/, you will be asked to login using allauth, then an oauth2 confirmation dialog appears, after which the oauth grant code is passed to a success URL. You can pick that code up from phonegap and using AJAX calls from within the phonegap app you can fetch the oauth access token. Btw, django-rest-framework has builtin support for django-oauth2-provider (don't know about tastypie).
A completely different approach is to implement a Facebook login in your mobile app, completely independent from the web site. Once logged in you'll be handed over a Facebook access token. Now, you can send this token over to the web site. Given the token, the website can fetch the user (https://graph.facebook.com/me?access_token=...), check whether or not that user is already known, if so return an appropriate token/session for that user, if not, create the user account and also return a token.

Facebook Integration Static access token

I'm trying to use the facebook API on the backend of a website. Essentially, I want to be able to create events using a Djano app and have it create the corresponding facebook events.
The organization I am creating events for already have a facebook page. I only am concerned with posting events on that organization's page. I am the admin for the organization so I know all the login info.
What I am am trying to figure out is how I can setup the access token such thatit just works for the organization without any need to login to the facebook app. I was thinking that setting a static access token would do the trick, but I cannot find anyway to do it.
So, what is the standard way to create a facebook app that only interfaces with one predefined user?
Im not entirely sure what you're trying to do. However the static access token has now been deprecated. Do you want to: create an event for the person using the page, or for the company's page/profile?
Hope I can help
