Does anybody know if there is a pluggable app that you can use to achieve url like image extraction for Django?
I dont know if there is a pluggable app that will do this for you, but you can probably hack this together yourself.
The only 'standard' I know of that facilitates this is oEmbed (http://www.oembed.com/) which basically works this way:
somebody gives you a URL.
you read it, find that its a valid JSON that matches the oembed structure
success!
other than the above, and what I think facebook does as well (since I took a look at a few sites that both twitter and fb would work with and none have any oembed support that I can see), is to work on a case by case basis. They probably had a developer go through a large variety of sites and look at the type of meta tags available. for example, yfrog has a bunch of meta properties that tell you the url directly to the main image being displayed, the owner, the tweet that went along with the image, etc. After that it's best effort guesswork. that's why when you try to share a blog post on facebook, it'll often give you the option of any one of the images that went with that blog post, because it doesn't know which one is the main one.

I am writing this question after considerable investigation into this matter.
I have gone through Google's easy dashboards (gadash JS library), superProxy and plain analytics API, and couldn't find the best solution for my needs, although I can't believe my needs are so uncommon.
This is why I am turning to you, I have got a feeling I am missing something.
My requirement:
Display my own analytics account data to users on my website, preferably with Google's chart API or ga-dash, to resemble google analytics views as much as possible.
Users will not have to take part in authentication with Google API
Each user has his own query which is built dynamically !! (this is probably why superProxy cannot work for me because I think you need to manually set the queries in advance)
I use django-python as the basis for my website
problems with solutions I tried:
GAdash library - the problem is that each user has to be authenticated, and shown their own data, meaning they need access to my profile- that's simply not what I am looking for. It works great, but only for me. On the other hand if there was a way to make my profile truly public...
superProxy - sounds like a solution for this need exactly, however I don't think that you can programmatically set the queries.
I did find a way to retrieve the data for a query on the server side using my own credential which is a bit hacky, I am still missing that JS library which will parse this XML on the client side and display it as charts.
EDIT:
I ended up using Mark's solution (embeddedanalytics), since I could not find a better, easier solution.
Other alternatives were:
1. superProxy (lacking the ability to dynamically, programmatically loading new queries)
2. gaDash library - requires authentication from each user
3. Implement my own server side querying, and display to the user with some js graphics library - which would require considerable work on my side.
Check out www.embeddedanalytics.com. This is a platform/service which will do exactly what you are looking to do (disclosure - I work with them).
We also support your requirement that each user have its own dynamically built query. This is what we call our CMS Integration version. Are you trying to create a dashboard system for a CMS system you have built?
How can one change the opengraph link value on a Facebook page (type: website) from
https://www.facebook.com/yourwebsite to http://www.yourwebsite.com
It seems easier than it is. I couldn't find an answer. Seems it has something to do with adding an app, and then?!
Example: http://graph.facebook.com/anguillabeachescom
I can’t see that being done anywhere on the page’s settings interface.
My guess would be you have to claim your domain with Facebook to make things work this way (and maybe have to have a special category set for your Facebook page – the example page you mentioned is of type “website”.)
This issue is very common in stackoverflow, and there's a lot of different questions and answers about it, yet I couldn't find exactly what I need.
First, I'd like to define exactly what I need: the option to let users log in to my app using their Facebook credentials. The app will save a matching classic Django user. I will only need to use the user's profile picture and to make sure that each time the same Facebook user will be related to the matching Django user.
Unfortunately, I find it really frustrating to implement for the following reasons:
By now, after reading a lot, I couldn't find out what is the best package for this task.
Some people recommend django-social-auth and praise its functionality and documentation. Personally, I don't understand why, since it's not specifically for Facebook and there are no explanations about the client side, i.e the Facebook login button and how the whole flow works.
When you go to Facebook developers, you suddenly find yourself reading about some magical javascript sdk, and about a promise that that's all you need. Then you get frustrated again and can't understand how a client side related sdk can sign up users to your app.
I know developers somehow implement Facebook auth packages in their apps, but I just can't figure out how to do it.
If anyone could tell me: at this time point, what is the best way to add Facebook authentication to my Django app? I would also ask for detailed documentation / tutorial that explains how to log in a Facebook user, from settings and configuration level through signup to Django app and to client side code.
There are multiple ways to approach the problem, what is the "best" way is really subjective.
Subjectively speaking, you could opt for django-allauth. Here are a few pointers to help you get started:
If you want to keep the signup simple, set SOCIALACCOUNT_AUTO_SIGNUP to True in order to achieve a "no questions asked" login. Users simply approve the FB dialog and they end up logged in in your site right away.
Adding a login button to your template is merely a matter of:
Sign In
The app offers support for the JS SDK login (pro: users are accustomed to the typical FB popup that appears), or you can use your own OAuth flow. Whatever you please.
The fastest way understand FB's Oauth 2.0 flow is to play with FB's Javascript SDK. Once you get the hang of it, the FB's PHP library is similar. Also, other OAuth sites like Google, Twitter or Dropbox have almost identical implementation.
In baby steps:
Learn how to install FB Javascript SDK onto a simple page
Use FB.login to determine login status and obtain the login url.
Lastly, use FB.Event.Subscribe and subscribe to auth.statusChange to detect the login/logout changes.
Also, good to check out https://developers.facebook.com/roadmap/ on the upcoming features or features being removed.
django-social-auth is not just for Facebook, but that doesn't mean you should use all the backends available.
Project documentation is at http://django-social-auth.readthedocs.org/en/latest/index.html and Facebook backend details at http://django-social-auth.readthedocs.org/en/latest/backends/facebook.html.
I've made a basic HTML5/JS comic creation tool that uses the canvas element.
I want users to be able to upload their comics via the Facebook API.
I don't believe Facebook allows posting images in the form of base64 strings from the canvas.toDataURI() method, and don't want to use my own server to convert these images & temporarily store them.
What's the best way to go about this? Possibilities I've wondered about: Convert canvas to blob? Store blob via web service (if so, suggestions?) Upload blob directly to Facebook? (Is that possible?)
I don’t see why this should not be possible doing a „normal” upload. You can create a new photo for a user by posting to PROFILE_ID/photos, with a source parameter of type multipart/form-data.
So first thing I’d try is getting the picture info from the canvas object into a „normal” form (writing it into a input element in the right format(?)), and sending that to Facebook. If this step succeeds, I’d see if jQuery or some other lib’s form.serialize method can build requests of type multipart/form-data. If that’s also possible, then there should be no further problem in taking the data in that format and posting it using FB.api (although you might want to tell your users to be patient, because that might take a while).
Can’t tell for sure if this’ll work, but I’d give it a try.
Facebook partners with Heroku for free app hosting, you can use it as the temporary server.
Sorry. Pretty new to this and trying to get a grasp on getting extended permissions/access_token for what I am trying to achieve.
All I need is to pull the public profile feed from someone's facebook page (returns in json format) so I can display it on said person's website. (I was going to parse this information using Jquery)
I think I understand that I will need to create an app in order to do this. Now will I need to create an app from said person's facebook account? Or is that something I can do myself, as a separate app?
Thanks for any info you can give on this.
You could in do it from both.
However im not 100% certain on if you would need any extra permissions from the target user or not. Because it is a public feed I would think not, but I haven't tried this myself so I can say for certain.
