Question

I\'m building a Facebook app using Python/Django. I\'ve installed FanDjango and that works great. Just one more thing I need.

I\'d like to build a \"like-gate\" fo

Answer 1

I'm no Facebook expert, and haven't played that much with the Facebook graph, but this should work.

Once you've authenticated the user, you can get their likes off the Facebook Graph:

https://graph.facebook.com/me/likes/{your_contents_graph_id}?access_token={access_token}

In Python I might query this via:

import requests
url = "https://graph.facebook.com/me/likes/{your_contents_graph_id}?access_token={access_token}".format(your_contents_graph_id=your_contents_graph_id, access_token=access_token)
r = request.get(url)
if r.status_code == '200':
    page_liked = True
else:
    page_liked = False

All this said, I wouldn't like your content. It's not appropriate for me or anyone else to like something they haven't reviewed in full. You might want to consider an alternative way to get people to look at your content.

Thanks. I got this to work by reading through the documentation in the facepy module I have installed. Here's how you access a user's "like" info for a particular page:

from facepy import SignedRequest
if 'signed_request' in request.REQUEST:
    signed_request = SignedRequest.parse(request.REQUEST.get('signed_request'), settings.FACEBOOK_APPLICATION_SECRET_KEY)
if signed_request.page.is_liked:
    test = "yes!"
else:
    test = "no!"

Fandjango wraps facepy so it's actually easier. Install only Fandjango via pip to avoid conflicts.

In the view with the request object, you can simply check against

request.facebook.signed_request.page.is_liked

and perform different actions. Remember that page will be None if the app is not in a page.
