    <p>I am trying to write a facebook app using app-engine-patch and pyFacebook. I am using nothing but the examples provided with each tool and for some reason it will not work.</p> <p>I have combined the two just as described in the accepted answet here: <a href="https://stackoverflow.com/questions/984071/facebook-django-and-google-app-engine">Facebook, Django, and Google App Engine</a></p> <p>app-engine-patch seems to work just fine but when I try to use @facebook.require_login() I get this from GAE's logs:</p> <pre><code>Exception in request: Traceback (most recent call last): File "/base/data/home/apps/app-name/1.339079629847560090/common/zip-packages/django-1.1.zip/django/core/handlers/base.py", line 92, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/base/data/home/apps/app-name/1.339079629847560090/facebook/djangofb/__init__.py", line 87, in newview if not fb.check_session(request): File "/base/data/home/apps/app-name/1.339079629847560090/facebook/__init__.py", line 1293, in check_session self.session_key_expires = int(params['expires']) ValueError: invalid literal for int() with base 10: 'None' </code></pre> <p>This happends no matter which view I decorate with @facebook.require_login()</p> <p>I am using the latest from both projects and I have no idea why it wont work.</p> <p>Many thanks for your time.</p> <p><strong>UPDATE:</strong> I made a quickfix for pyFacebook, but I just forgot to put it back in the thread.</p> <p>Now also as an answer, since it seems to be the only way.</p> <p>If you change facebook/__init__.py line 1292+ from this:</p> <pre><code> if params.get('expires'): self.session_key_expires = int(params['expires']) </code></pre> <p>To this:</p> <pre><code> if params.get('expires'): if params['expires'] == 'None': params['expires'] = 0 self.session_key_expires = int(params['expires']) </code></pre> <p>It will work, but it is a hack and maybe it could be done more elegantly, but it works. Gotta point the pyFacebook devs to this thread, maybe they will have a better solution.</p>

    1. COI'm having the same problem. Where in the directory structure of the sample AEP application did you put the PyFacebook stuff?

    2. COOh btw, the reason this happens is because a browser cookie, which the Facebook code expects to be None is set to the string, "None" and then tries to get parsed. I don't know why that cookie is set or what the bug is, put that's why it happens. You'll find if you clear your cookies, then hit your site, it'll suddenly redirect to Facebook. That doesn't solve the problem, but it's a little more info.

    3. COI put the facebook dir in the root of the AEP-sample dir. Just as described in the link and they seemed to be able to make it work. Thanks for the tip with the cookie, will try to tinker a little with it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
