How can I force chrome to get the geolocation from GPS module connected to a USB port instead of getting it from router IP?
I'm working on a certain project that uses RasberryPi debian 7 google chrome to open get some work done, the thing is, the server (I made it with django) asks the rasberry pi about its location.

Django save/ store queryset to be used in different views
So I'm not really sure how to call this, and thus not really able to find a solution... Let's say I have two views created, "CheckInsListView" and "CheckOutsListView". These are being filtered on the status = "CI" or status = "CO". Next would be that I'd like to show the results for a user given date, so I'd make a form "DateSelection" and use a "get_queryset" to match the date and show the results. Now the problem is, when I switch views, the user given date get's lost. Would there be a way to keep the date saved/ stored somwhere? So the user can check the "Check-ins" and "Check-outs" for a particular date without selecting the date twice... #views.py class CheckInsListView(generic.ListView, FormMixin): form_class = DateSelection model = Orders paginate_by = 10 queryset = Orders.objects.filter(status='CI') template_name = 'check-ins.html' class CheckOutsListView(generic.ListView, FormMixin): form_class = DateSelection model = Orders paginate_by = 10 queryset = Orders.objects.filter(status='CO') template_name = 'check-outs.html' Thanks for the help! -

Easy-thumbnails unwanted image rotation
I faced with such thing using easy-thumbnails: users upload different photos on my website and sometimes these photos are not right oriented. For example, user uploaded a photo. And when the photo is thumbnailed, it displays good, but if I try to display origin image - it is rotated. And it is rotated wrong. Is there a solution to process image but not to resize in easy-thumbnails Or I googled such solution: run images with jhead before upload <img> unwanted photo rotation Of course, I can`t say users to run the image with this program, but I need to integrate it into my django app. As for me, It would be better to make thumbnail without cropping, but, as I understand, crop attribute is mandatory in easy-thumbnails. What do you suggest? Thanks a lot! -

Django - run a function every x seconds
I'm working on a Django app. I have an API endpoint, which if requested, must carry out a function that must be repeated a few times (until a certain condition is true). How I'm dealing with it right now is - def shut_down(request): # Do some stuff while True: result = some_fn() if result: break time.sleep(2) return True While I know that this is a terrible approach and that I shouldn't be blocking for 2 seconds, I can't figure out how to get around it. This works, after say a wait of 4 seconds. But I'd like something that keeps the loop running in the background, and stop once some_fn returns True. (Also, it is certain that some_fn will return True) -

Django: Specific model's links redirect to a non-admin view instead of the default page listing that model's information
I'm working on an app which supports user image uploads. Uploading images to a model works fine; I have a working Upload view which renders a form that handles these uploads. I want to be able to see and manage the model's fields from the admin interface, which leads to my question specified in the title. Using another model (Topic) as an example, what I expect is for this admin page to show up when I click its link on the admin site. But when I click the link for the model ImageUpload, the non-admin Upload view shows up instead. The second link shows that an admin-site url is rendering what I expect to be a non-admin-site page.
