Postgresql database throwing errors on connection
I am running a Postgresql database on AWS and the backend is Django. After some requests, let's say 50, it raises the error "OperationalError: terminating connection due to administrator command SSL connection has been closed unexpectedly" but the database will still remain active. At first, it was throwing "OperationalError: FATAL: remaining connection slots are reserved for non-replication superuser connections" after some requests, so I have a script that closes open connections. Here is the script: export PGPASSWORD='mypassword' psql --host=dbhost.myregion.rds.amazonaws.com --port=5432 --username=user --dbname=name \ -c "SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE pid <> pg_backend_pid() AND state in ('idle', 'idle in transaction', 'idle in transaction (aborted)', 'disabled') AND usename != 'rdsadmin';" but the errors keep coming. I have also tried increasing the max_connections to 150, but it still doesn't help. I have also tried using AWS RDS proxy, but still no hope. Here is how I connect to the DB from django: DATABASES = { 'default': { 'ENGINE': config('DB_ENGINE'), 'NAME': config('DB_NAME'), 'USER': config('DB_USER'), 'PASSWORD': config('DB_PASSWORD'), 'HOST': config('DB_HOST'), 'PORT': config('DB_PORT'), 'CONN_MAX_AGE': 0 } } -
Drf class based view how to manage method calls
I have been working on FBV in Django and am now trying out CBV. I have created a basic crud application Views.py class UserViews(APIView): permission_classes = [IsViewOnly | IsManager | IsAdmin | IsStaff] def get_objects(self, user_id): #query def post(self, request): #create code def get(self, request): #details code def put(self, request): #update code def delete(self): #code urls.py urlpatterns = [ path('add-user/', views.UserViews.as_view(), name="create-user"), path('update-user/', views.UserViews.as_view(), name="update-user"), path('delete-user/', views.UserViews.as_view(), name="delete-user"), path('list-users', views.UserSearchList.as_view(), name="list-user"), path('view-user', views.UserViews.as_view(), name="view-user"),] This code is working but, how do we prevent a situation where say a manager wants the view user details API but executes it with the delete method and the user is now deleted -

Need for installing a server for django app deployment on various hosting sites
On finishing with a django site, do I need to install for e.g nginx and uwsgi before uploading it to heroku or pythonanywhere? If no, does it mean heroku or pythonanywhere provides the server for me? And which places do not provide the server and I therefore need to install nginx and uwsgi or gunicorn. What are the differences between those that provide the server and those that don't? Which is good? -
How to retrieve the docker image of a deployment on heroku via circleci
I have a django application running locally and i've set up the project on CircleCi with python and postgres images. If I understand correctly what is happening, CircleCi would use the images to build a container to test my application with code database. Then I'm using the job heroku/deploy-via-git to deploy it to Heroku when the tests are passed. Now I think Heroku is using some images too to run the application. I would like to get the image used by heroku to run my site locally on another machine. So pull the image then push it to Docker Hub and finally download it back to my computer to only have to use a docker compose up. Here is my CircleCi configuration's file version: 2.1 docker-auth: &docker-auth auth: username: $DOCKERHUB_USERNAME password: $DOCKERHUB_PASSWORD orbs: python: circleci/python@1.5.0 heroku: circleci/heroku@0.0.10 jobs: build-and-test: docker: - image: cimg/python:3.10.2 - image: cimg/postgres:14.1 environment: POSTGRES_USER: theophile steps: - checkout - run: command: pip install -r requirements.txt name: Install Deps - run: name: Run MIGRATE command: python manage.py migrate - run: name: Run loaddata from Json command: python manage.py loaddata datadump.json - run: name: Run tests command: pytest workflows: heroku_deploy: jobs: - build-and-test - heroku/deploy-via-git: requires: - build-and-test … -

Overwrite/replace instead of update MySql table in a Django Project
Let's say I have df1 which is pulled from a MySql database in a django project: import pandas as pd df1 = pd.DataFrame({'Name': ['John', 'Jim'] ,'City': ['A', 'B'],'Project_id': 1}) df1 Then my function within django adds two rows: line_insert = pd.DataFrame({'Name': ['Jack', 'Jill'] ,'City': ['C', 'D']}) df1 = df1.append(line_insert).reset_index(drop=True) df1 Now i would like to save this dataframe back to the table in the database. My current code updates the sql table row by row (where Project_id = 1) but i am wanting to replace the dataframe with the same Project_id My current code to update the table is (for simplistic sake i have defined some variables first): proj_id = 1 iincreament_id = 1 for index, df_series in df1.iterrows(): dict_df = df_series.to_dict() """ Insertig dataframe into dict """ dict_df['Projectid_id'] = proj_id """ updating SQL DB """ sql_db.objects.filter(id=iincreament_id,Project_id=proj_id).update(**dict_df) iincreament_id += 1 So what this does is updates row 1 & 2 values with their new values but does not replace the sql table with the new table to bring in rows 3 & 4. Is there any ideas on a replace function using the .objects functions with python/django? Thanks very much! -

Redirect non authenticated user to login page (for all views)
I am looking to redirect my user to login page, if they have not logged in. I initally looked at the decorator @login_required(login_url='/accounts/login/'). But this is not ideal, for 2 reasons: first I want this to apply to all views. Also the decorator returns an error message when I try to login with allauth. I am sure this is solvable, but I am looking for a solution that could apply to all views. I found something using authmiddleware(doc: https://pypi.org/project/django-authmiddleware/). However the code doesn't not seem to be responsive, in the sense nothing is happening and the logs on the console don't seem to pick up anything. Can someone see what I am doing wrong? base.py MIDDLEWARE = [ 'django.contrib.sessions.middleware.SessionMiddleware', 'AuthMiddleware.middleware.AuthRequiredMiddleware', ] AUTH_SETTINGS = { "LOGIN_URL" : "login_user", "DEFAULT_REDIRECT_URL" : None, "REDIRECT_AFTER_LOGIN" : False, } views.py from django.shortcuts import render, redirect, reverse from django.http import HttpResponse, HttpResponseRedirect from django.contrib.auth import authenticate, login, logout, get_user_model from django.urls import reverse class AuthRequiredMiddleware(object): def process_request(self, request): if not request.user.is_authenticated(): return HttpResponseRedirect(reverse('login_user')) return None -
django: unable to login after successful registration
login reporting wrong username or password, after a new user is registered successfully. I am sure the there is no typo! below is my code and I guess the problem is to do with the hash code related to the password setup? @csrf_exempt def api_register(request): data = json.loads(request.body) username = data['username'] password_1 = data['password_1'] password_2 = data['password_2'] # 1，check if two pw is same if password_1 != password_2: return JsonResponse({"code": 0, "msg": "pw not consistant"}) else: m = hashlib.md5() m.update(password_1.encode()) password_m = m.hexdigest() # 2 check if username exists users = User.objects.filter(username=username) if users: return JsonResponse({"error": "username already exists"}) else: try: user = User.objects.create_user(username = username, password = password_m) user.set_password(password_m) user.save() user.is_active = True user.success = True ret_data = {"username": user.username, 'uid': user.id, 'password': user.password} token = TimestampSigner(sep='.').sign_object(ret_data) ret_data['token'] = token ret = {"code": 1, "msg": ret_data} except Exception as e: print('--create user error is %s' % e) return JsonResponse({"error": "username already exists"}) return JsonResponse(ret) below is login function @csrf_exempt def api_login(request): data = json.loads(request.body) user = authenticate(**data) #same as authenticate(username=data['username'],password=data['password'] if user: ret_data = {"username":user.username,'uid':user.id} token = TimestampSigner(sep='.').sign_object(ret_data) ret_data['token'] = token ret = {"code":1,"msg":ret_data} print("ret ", ret) else: ret = {"code":0,"msg":"username or password wrong!" } return JsonResponse(ret)
