How to prevent primary key from appending to django rest framework url
I have a django project and i am trying to integrate django rest framework into it. I currently have a viewset and I want to do two things. I want to add two filter parameters into the url and grab them in the viewset and use them in the queryset to filter records that match those filters. I also want to prevent the primary key filter to append to the url when i try to access the viewsets... Here is the url: router.register(r'preferences/(?P<namespace>.+)/(?P<path>.+)', PreferencePathViewSet, basename='Preference-path') router.register(r'preferences/(?P<namespace>.+)', PreferenceNamespaceViewSet, basename='Preference-namespace') router.register(r'preferences', PreferenceUserViewSet, basename='Preference') Here is the viewsets: class PreferenceUserViewSet(viewsets.ModelViewSet): model = Preference serializer_class = PreferenceSerializer def get_permissions(self): if self.action == 'create' or self.action == 'destroy': permission_classes = [IsAuthenticated] else: permission_classes = [IsAdminUser] return [permission() for permission in permission_classes] @permission_classes((IsAuthenticated)) def get_queryset(self): queryset = Preference.objects.filter(user_id=1) return queryset class PreferenceNamespaceViewSet(viewsets.ModelViewSet): model = Preference serializer_class = PreferenceSerializer lookup_namespace = 'namespace' def get_permissions(self): if self.action == 'create' or self.action == 'destroy': permission_classes = [IsAuthenticated] else: permission_classes = [IsAdminUser] return [permission() for permission in permission_classes] @permission_classes((IsAuthenticated)) def get_queryset(self): namespace = self.request.query_params.get('namespace') queryset = Preference.objects.filter(user_id=1, namespace=namespace) return queryset class PreferencePathViewSet(viewsets.ModelViewSet): model = Preference serializer_class = PreferenceSerializer lookup_namespace = 'namespace' lookup_path = 'path' def get_permissions(self): if self.action == 'create' … -
Azure development center unsupported python version error
I am attempting to get a Django website hosts on Azure that I build in Visual Studio. I am able to publish it and get a dedicated url, however in order to get the site to load properly I need to load my code to azure.

Django REST framework. How i can make export model in csv

I mean, how i can get data like student full name and etc. I will be grateful for the help -
Imported script executing itself in a unittest class even though if __name__ == "__main__" guard is present
Testing functions from an imported python script which creates django boilerplate leads to said function executing itself when the test is run. The testing file is in the same folder as the script being tested. The testing file includes unittest.main() as per the unittest documentation. The tested script also includes if __name__ == "__main__" under which is the main function calling all the other functions in the script. If I put if _name__ == "__main__" at the top of the tested script and run the entire script under that if block, the script still works as intended, however an ImportError is thrown upon running the testing file. Link to the script(It's not very long): https://github.com/PersonRP7/django_tests_generator_standalone/blob/functional_refactor/mts_functional.py import unittest import mts_functional class TestMakeTestStandalone(unittest.TestCase): def test_set_app_name(self): app_name = "one" response = mts_functional.set_app_name() self.assertEqual( response, "one" ) When I run the above test(either in Atom, or in the powershell, using python -m unittest discover), I am prompted for the app_name and if my answer corresponds to the app_name variable defined in the test_set_app_name(self), the test passes. If it doesn't, the test fails. I've also tried importing individual functions using from mts_functional import some_function, but the result was the same. I'm not sure if this … -
How to extend the event/occurrence models in django-scheduler
I'd like to augment events/occurrences in django-scheduler with three things: Location Invitees RSVPs For Location, my initial thought was to subclass Event and add Location as a foreign key to a Location class, but my assumption is that each occurrence saved won't then include Location, so if the location changes for one occurrence, I'll have nowhere to store that information. In this situation, is it recommended to create an EventRelation instead? Will I then be able to specify a different Location for one occurrence in a series? The EventRelation solution seems untidy to me, I'd prefer to keep models in classes for clarity and simplicity. I think Invitees is the same problem, so presumably I should use a similar solution? For RSVPs, I intend to make an RSVP class with Occurrence as a foreign key, and as far as I can tell that should work without any issues as long as I save the occurrence before attaching it to an RSVP? I've read all the docs, all the GitHub issues, various StackOverflow threads, the tests, the model source, etc, but it's still unclear what the "right" way to do it is. I found a PR which introduces abstract models: https://github.com/llazzaro/django-scheduler/pull/389 … -

How to set multiple rate limits , per 10sec, per 10min, per 1 day using django-ratelimit or throttling?
I want to set the rate limits for my views based on duration of 10sec, 10min and 1 day. So let say user can send 20 requests/ 10 sec, 100 requests/ 10min and 1000 request per day. I have tried throttling but couldn't find any way to set multiple requests. I have tried django-ratelimit package, but i couldn't find any such option in that too as it sets a single string for rate, such as rate = '5/10m'. Please let me know if there is any way out to solve this problem -
How to return a 404 for paths that do not exist in a Django app?

Django Image processing app ? where should i call the imageprocess function ? in the views or the forms?
I want to make a django app where i can process Images and show both the preprocessed and the processed,i have the function already ready and tested,how i should implement it? I already developed mini apps where it basically takes a user input without actual processing just showing it in views with some restriction and validations.I have a basic idea how i should construct the model of this app and it looks like this: class Image(models.Model): user = models.ForiegnKey(user,on_delete=models.CASCADE) preprocessed = models.ImageField(upload_to=user_path) processed = models.ImageField(upload_to=another_path) so should i call the process function in the views/forms ? I think it's in the views but how it should really looks like? should i call the form and save the input from the form if it's valid to the model ? how should i call the image preprocessed to process it and show it in a detail view ? -

Create multi page pdf report from class objects using XHTL2PDF
I would like to create a multi-page pdf report that creates a new page for each class instance. I store each instance in a list called objects and would like to duplicate each pdf created as a new page in the full pdf report. Right now when I generate the pdf I can get a 1 page report that includes the [0] index. I would like to know how to loop through all indexes of this class and create a new page for each instance. def generate_pdf(request, *args, **kwargs): for x, y in enumerate(Store_Objects.objects): template = get_template('payback/pdftemplate2.html') context = { "store_name": Store_Objects.objects[x].store_name } html = template.render(context) pdf = render_to_pdf('payback/pdftemplate2.html', context) if pdf: response = HttpResponse(pdf, content_type='application/pdf') return response return HttpResponse ("Could not Render PDF") I would like to know how to create a page break and duplicate the exact pdf template but with attributes from the next instance. I'm assuming it has something to do with the return response but I can't figure out what needs to be there to create a new page and continue the loop. -

Django 2.3: I committed my secret key to a private repository. Can I just edit the secret key myself and then add .env file to .gitignore?
So in being a newb to Django I accidentally committed my secret key to a private repository that I have for my website. Considering that I intend to use this site for business purposes, I want to make sure that it is secure as possible. Do I need to generate a whole new Django Key? Or could I possibly just edit lets say, 10 characters of the secret key, add the edited secret key to my .env file, add the .env to my .gitignore file and call it a day? I recognize this is not the best approach. I will most likely completely generate a new secret key but I thought this might be an effective quick fix. I figure that by doing it this way the new secret key is still randomly generated and the old one is still available on github but useless to anyone who happens to scrape it. FYI I am using python-decouple with a .env file which is where I save all my secret variables (aws info, secret key, db info, etc.). I have separate settings files (production.py, development.py, common_settings.py) where both production.py and development.py import all of the data from common_settings.py. I just happened … -

Hidden Button Not Hiding with setInterval
I have a Django app where a user enters an Elasticsearch query and it generates a downloadable document. I have a Download Report button that is supposed to appear once the report is done being generated. However, it shows up at first then checks if the report is generated before disappearing until the report is done. What do I need to modify in my code for the button to hide until the report is done, and not show up before? Note: I am aware my button is not functional and not pointing to anything, I'm still trying to work on that. views.py def check_progress(request): """ Returns status of document generation """ fn = request.POST["filename"] file = "/app/created_files/" + fn if not os.path.exists(file): return JsonResponse({"report_in_progress": 1}) else: return JsonResponse({"report_in_progress": 0}) check.html <!-- templates/django_audit/check.html --> {% extends 'base_login.html' %} {% block title %}Please wait{% endblock %} {% load static %} {% block content %} <script type='text/javascript' src="{% static "bootstrap/js/jquery/1.7.1/jquery.min.js" %}"></script> <script type="text/javascript"> $(document).ready( function() { var fn = $('#fn').val() var checkInterval = setInterval(isFileComplete, 3000); //3000 is 3 seconds function isFileComplete() { $.ajax({ url: '/check_progress/', type: 'POST', data: { 'filename': fn, 'csrfmiddlewaretoken': '{{ csrf_token }}', }, dataType: 'json', success: function (data) { if …
