Django get wrong value from json.loads in POST request
I need to pass a user-input geojson with request to further process the information. The data comes from a textfile and then passed to the views.py in django with a POST request. Before passing to the view I checked the value of the string and that appears to be correct. After passing that to the view, I made a print check and some values inside the JSON are changed in string like: "{"id": "13871", "type":SOH@ "Feature", "properties": {"lanes": 0, "highway": "pedestrian" etc....." or "{"id":"86","type":"FeatureSOHVT","properties":etc......." The bold strings sometimes appear even inside the values of the dictionary. The js file: $.ajax({ type: 'POST', url: $('#confImp').data('url'), dataType: 'json', data: {'streetWeb': JSON.stringify(street_web), 'int_points': JSON.stringify(int_points_loaded), 'csrfmiddlewaretoken': csrftoken,}, success: function(res){blablabla} The django views.py: elif 'streetWeb' in request.POST: print(json.loads(request.POST.get('streetWeb'))) request.session['Working_area_final'] = json.loads(request.POST.get('streetWeb')) print(json.loads(request.POST.get('int_points'))) request.session['int_points'] = json.loads(request.POST.get('int_points')) return JsonResponse({'Risposta': 'Done'}) -
Code works fine without subquery, why to use it?
newest = Comment.objects.filter(post=OuterRef('pk')).order_by('-created_at') posts = Post.objects.annotate(newest_commenter_email=Subquery(newest.values('email')[:1])) And, newest = Comment.objects.filter(post=OuterRef('pk')).order_by('-created_at') posts = Post.objects.annotate(newest_commenter_email=newest.values('email')[:1]) Both, works fine then why use a Subquery, what are its advantages? -

What is the meaning of this wsgi apache error log message (in django)
My django site seems to be working without any problems. But, looking at the apache2 error log, I frequently see this message (but no traceback or anything like it) [Thu Dec 22 16:37:32.948596 2022] [wsgi:error] [pid 763796:tid 140436065670912] [remote xxx.xxx.xxx.xxx:63167] [<JobsListUser: Jillian>] [Thu Dec 22 16:37:32.948671 2022] [wsgi:error] [pid 763796:tid 140436065670912] [remote xxx.xxx.xxx.xxx:63167] ja I have a model called JobsListUser, and these 2 lines appear repeatedly for all users (for example, [<JobsListUser: Kelly>] etc.) I assume the 'ja' is code of some kind for japanese (the site is viewable in english and japanese, but i've never seen an error) Can someone explain this to me? I want to know what the error is and if I need to fix it. I can't see any information in the log telling me which part of the code is generating the error. -

Application and request contexts in Flask
I really need your help.

I don't understand how they work. Every time a request is made to a web app developed with Flask a new instance of the Flask class is created or really how a Flask app works under the hood. It would be very helpful if you help me solve this doubt that is driving me crazy. Thank you very much in advance. I've read everywhere and I still don't understand. -

Django OAuth Authentication
I built an app (Django backend, React frontend) that whenever a client login it will generate JWT authentication. React will store the access token and client can use it to access Django backend database. Then I want to add in social login feature (Google) so I will get back access token from that as well. However, this access token is different from the JWT access token generated before, so I wonder how can I integrate both ways of logging in a user smoothly on both Django and React?

I have tried hard coding it in, I have tried different ways of writing the url, I have tried changing the syntax (in case I am doing it incorrectly. I have checked the page source when I have run tests. I …
