python - Missing OAuth request token cookie error using tornado and TwitterMixin -

-

i'm using tornado , twittermixin , use following basic code:

class oauthtwitterhandler(basehandler, tornado.auth.twittermixin):      @tornado.web.asynchronous      def get(self):          if self.get_argument("oauth_token", none):              self.get_authenticated_user(self.async_callback(self._on_auth))              return          self.authorize_redirect()      def _on_auth(self, user):          if not user:              raise tornado.web.httperror(500, "twitter auth failed")          self.write(user)          self.finish()

for me works sometimes, users of application 500 error says: missing oauth request token cookie

i don't know if comes browser or twitter api callback configuration. i've looked through tornado code , don't understand why error appears.

two reasons why might happen:

  1. some users may have cookies turned off, in case won't work.
  2. the cookie hasn't authenticated. it's possible oauth_token argument set, cookie not. not sure why happen, you'd have log logging understand why.

at rate, isn't "error," rather sign user isn't authenticated. maybe if see should redirect them authorize url , let them try again.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
