How to get null for rows where data doesn't exist in Postgres while performing joins
I have 2 tables. Items and Rates. All the items are stored in items table and rates are stored daily in rates table. Items and rates are linked using FK on rates table. When the rates are stored if it is not preset then row is not stored. Like for item 5 if no rate is present on 1st jan, there wont be a record for item 5. When getting the data I want item 5 rate as null (as shown in example pic). How can I proceed? I tried left joins, left Join is not working, sometimes depending on the data I get the date as null, sometimes everything except item pk is null. I dont know how to proceed furthur with this. -
Error while passing Variable from View to Form in Django
I try to send a variable form View to Form in Django. I find a solution and it's working but the problem is that I have to call the fonction form = DonneeForm(variable=variable) but it seems to just send me the entire HTML code. So I would like to find a way for the DonneeForm() to behave as DonneeForm which work but doesn't allow me to send a variable.

Django : Fix admin link to website ressources when apps are in subfolders
Here is the architecture of my django project : project/ apps/ app1/ app2/ ... core/ management/ settings.py ... static/ templates/ utils/ It is not a conventional tree, but it works pretty well. Problem I have is with reverse admin urls. Django admin provide direct links to resources which are broken, giving me the following error : Reverse for 'pattern_name' not found. 'pattern_name' is not a valid view function or pattern name. pattern_name does exists indeed, but is behind app app1, and should be called app1:pattern_name. I don't find any documentation about this. Is there a way to fix it ? -
Django auth crash

How to implement auto-refresh jwt token in server side (DRF)?
I want to refresh my jwt access token automatically when the access token expires. (only in server-side, I'm using Django) Also, I am storing tokens in HttpOnly Cookie. This is my DEFAULT_AUTHENTICATION_CLASSES in my settings.py. 'DEFAULT_AUTHENTICATION_CLASSES': ( 'account.authenticate.CustomAuthentication', 'rest_framework_simplejwt.authentication.JWTAuthentication', ), I checked that authentication works everytime I get URL. So I tried to add code about Refreshing token in my custom Authentication class which overrides JWTAuthentication. ( JWTAuthentication document ) authenticate.py class CustomAuthentication(JWTAuthentication): def authenticate(self, request): header = self.get_header(request) if header is None: raw_token = request.COOKIES.get(settings.SIMPLE_JWT['AUTH_COOKIE']) or None else: raw_token = self.get_raw_token(header) # if access_token expires if raw_token is None: refresh_token = request.COOKIES.get(settings.SIMPLE_JWT['AUTH_COOKIE_REFRESH']) or None serializer = TokenRefreshSerializer(data={'refresh': refresh_token}) # if refresh_token is valid if serializer.is_valid(): raw_token = serializer.validated_data['access'] # set cookie about access_token response = HttpResponse() response.set_cookie( key=settings.SIMPLE_JWT['AUTH_COOKIE'], value=raw_token, max_age=3600, # 1 hour secure=settings.SIMPLE_JWT['AUTH_COOKIE_SECURE'], httponly=settings.SIMPLE_JWT['AUTH_COOKIE_HTTP_ONLY'], samesite=settings.SIMPLE_JWT['AUTH_COOKIE_SAMESITE'] ) validated_token = self.get_validated_token(raw_token) enforce_csrf(request) return self.get_user(validated_token), validated_token And these are the problems. It can't return response. So, the cookie(access_token) can't be set in the request.header. Explanation about authenticate in simplejwt-document authenticate(request) Authenticate the request and return a two-tuple of (user, token). The Cookie (access_token) is not in the request.header. So it always generate new access_token. Cookie's max age doesn't work after access_token … -

Django QuerySet incorrectly has size 0 but has an element
When I make a query on a model with a Model.objects.filter(filters) call, it returns a queryset with all the elements that satisfy the filters passed present in it. as expected. However, in this particular case, Django returned a queryset that looks like this: which should already be impossible. As you can see, the size of the queryset is 0, Model.objects.filter(filters).count() returns 0, as does len(list(Model.objects.filter())), which is supposed to force evaluate the query, and should have returned a queryset of size 1 with the element. I know that the size of the queryset should have been 1 because Model.objects.get(filters) returns the object as expected in the debugger evaluation window. One thing that might be of interest is that this behaviour is corrected when a previous filter call is removed. The Case: Initial state: There is a table that corresponds to a django.models.Model in Django, and has 0 rows and 0 constraints. Steps to replicate: Evaluate a query using Model.objects.filter(a=x,b=y) where a and b are columns in Model and x and y are valid values, and neither a nor b are primary keys. Since the table is empty, the result will be an empty queryset. Create an object with a=x and … -

When I execute the application with a certain number of input values Django's terminal (I'm using PyCharm) shows these things: Signal received: -250068120, errno: 32607 ################################################################################ Stack trace: ################################################################################ /usr/local/lib/python3.8/dist-packages/_awscrt.cpython-38-x86_64-linux-gnu.so(aws_backtrace_print+0x4f) [0x7f5ff65c392f] /usr/local/lib/python3.8/dist-packages/_awscrt.cpython-38-x86_64-linux-gnu.so(+0x726c3) [0x7f5ff65316c3] /lib/x86_64-linux-gnu/libc.so.6(+0x43090) [0x7f6046e9b090] /usr/local/lib/python3.8/dist-packages/dwave_qbsolv/qbsolv_binding.cpython-38-x86_64-linux-gnu.so(tabu_search+0x475) [0x7f5ff1cc8c35] /usr/local/lib/python3.8/dist-packages/dwave_qbsolv/qbsolv_binding.cpython-38-x86_64-linux-gnu.so(solve+0x990) [0x7f5ff1cca4b0] /usr/local/lib/python3.8/dist-packages/dwave_qbsolv/qbsolv_binding.cpython-38-x86_64-linux-gnu.so(+0x17915) [0x7f5ff1cd6915] /usr/local/lib/python3.8/dist-packages/dwave_qbsolv/qbsolv_binding.cpython-38-x86_64-linux-gnu.so(+0x1af96) [0x7f5ff1cd9f96] /usr/bin/python3(PyCFunction_Call+0x59) [0x5f5b39] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x62cd) [0x57165d] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(PyObject_Call+0x62) [0x5f52b2] /usr/bin/python3(_PyEval_EvalFrameDefault+0x1f2c) [0x56d2bc] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3() [0x50b32c] /usr/bin/python3(PyObject_Call+0x62) [0x5f52b2] /usr/bin/python3(_PyEval_EvalFrameDefault+0x1f2c) [0x56d2bc] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x851) [0x56bbe1] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3(_PyEval_EvalFrameDefault+0x726) [0x56bab6] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3(PyObject_Call+0x62) [0x5f52b2] /usr/bin/python3(_PyEval_EvalFrameDefault+0x1f2c) [0x56d2bc] /usr/bin/python3() [0x50b22e] /usr/bin/python3(_PyEval_EvalFrameDefault+0x726) [0x56bab6] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) [0x570b82] /usr/bin/python3(_PyFunction_Vectorcall+0x1b6) [0x5f5ee6] /usr/bin/python3() [0x59cb2e] /usr/bin/python3(_PyObject_MakeTpCall+0x296) [0x5f6706] /usr/bin/python3(_PyEval_EvalFrameDefault+0x59a4) [0x570d34] /usr/bin/python3(_PyEval_EvalCodeWithName+0x26a) [0x569d8a] /usr/bin/python3(_PyFunction_Vectorcall+0x393) [0x5f60c3] /usr/bin/python3(_PyEval_EvalFrameDefault+0x57f2) … -
Include additional details in Django error log for improved debugging?
Let's say I have a simple django view like so # views.py def view1(request): val = 5 / 0 return JsonResponse({"val": val}) and I have the following config for logging with debugging intentionally set to False # settings.py DEBUG = False LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': f'{BASE_DIR}/logs/debug.log', }, }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'DEBUG', 'propagate': True, }, }, } If I were to call the view, I would see the following statement in my logs Internal Server Error: /view1/ Traceback (most recent call last): File "/opt/pyenv/versions/3.10.8/lib/python3.10/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) File "/opt/pyenv/versions/3.10.8/lib/python3.10/site-packages/django/core/handlers/base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/code/app1/views.py", line 14, in view1 val = 5 / 0 ZeroDivisionError: division by zero I can easily enable monitoring alerts to be notified of such errors like these when they occur. And I can inspect the log to see what line failed with what exception. But I am lacking other vital information in order to fully debug the issue. How can I include additional details into this log? Details such as the URL that was called, query parameters, the incoming payload, … -
