There are lots of posts about magic behaviour of VK API. But yeasterday I faced another one. I have simple button on my site to share page on VK using Wall.post of OpenAPI, and yesterday I found out that it stopped working. After debuging I found error in API response: Permission to perform this action is denied for non-standalone applications: you should request token using blank.html page. The magical thing was that this error appears only on one type of pages, while on another everything was fine.
Short sqlalchemy query to get highcharts ready data from database from datetime field. select count(1), extract(epoch from date_trunc(‘hour’, created_at)) from bid group by extract(epoch from date_trunc(‘hour’, created_at)); db.session .query( extract(‘epoch’, func.DATE(Bid.created_at)).label(‘dt’), func.count() ) .filter(Bid.ownership == o) .filter(Bid.created_at > days_to_count ) .group_by(‘dt’) .order_by(‘dt’) )
For one of my projects I needed to post messages to Facebook Fan Page. After initial search I found out that Facebook has never-expiring token specially for this. It looks like trivial task and I was really surprised when I didn’t find any one-page step-by-step manual to get it. I decided to write all steps from the beginning, not only part about gettting never-expiring token.
