Re: Redirect and execute after 2 seconds?

Maria,

If the id is truely unique (is never used again for another version of the poll), then the fact that the browser visits the URL containing the ID gives you a chance to note the missed question.

Separately, you may want to look into Django's session stuff, since you then need not encode answer/non-answer IDs into the URL.  The session cookie associates a particular set of session data with requests from this browser.  Then all poll takers can share the same set of URLs, which might be unique to a question, or could be generic, with which question is currently being answered or missed stored on the session.  You might, in fact, use the same URL for everything, making the buttons submit buttons of a form, where which submit button is pressed is encoded in the query parameters, and the timeout submits to a hard coded URL that is either recognizable because it doesn't have that query parameter, or has the equivalent of a "timed out" or "skip" button hard coded in its query parameters.  Either way, using the session saves you from having to generate and match upon your "random" IDs.

Thank you Bill! I dont know if I got you but if I do it with JavaScript I can't save the ID of the "missed" page, can I?

Because I want to save the page where no button was clicked to show it again at the end of the poll, so that the user gets another chance to answer this question.

You must do this using JavaScript in the user's browser.  Look for time based events in JavaScript, including how to cancel them if a button is pressed.  The button should still probably submit to the Django server for recording, but you could simply record the fact that the correct (pseudo-)random id was visited.  You will have to record the GET for the time out case.  The time out handler can simple write to window.location to accomplish the "redirect" (which isn't really a redirect in the strict sense, since it doesn't occur as part of fetching a different page).  And that's JavaScript on the browser writing window.location, NOT anything within Django.

Hi everyone! :)

 

I am working on a project for my studies, it is a web poll where you can only answer yes or no by clicking on buttons.

 

If the user clicked on one button, the result will be saved in a text-file and the user will be redirected to another page with a random id:

 

return HttpResponseRedirect ('/polls/'+str(sid))

 

If the user doesnt click on any button quickly enough, I want the page to redirect them after 3 seconds to another page with a random id AND i want to save the id of the question that wasnt answered.  How can I do it? I searched the web but only found the time.sleep function. As far as I understood, I cant use the sleep function because the site has to do other stuff while the 3 seconds pass.

 

I would be very thankful for any help on this!

 

Kind regards,

 

Maria
