Problem with django foreign key auth_user
I am developping a HR project with django. I want to save the information which user modified my person model the last time. Therefore, my model.py contains lines like these: class person(models.Model): modified_by = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, on_delete=models.SET_NULL, related_name='person_modified', verbose_name='Modifiziert von') In admin.py, I save the modified_by information like this def save_model(self, request, obj, form, change): obj.modified_by = request.user However, my class person is also my authentication user model, as defined in settings.py AUTH_USER_MODEL = 'person.person' I assume that in my database, modified_by directly refers to my AUTH_USER_MODEL. But the database looks like this: "person_person_modified_by_id_5069ed54_fk_auth_user_id" FOREIGN KEY (modified_by_id) REFERENCES auth_user(id) DEFERRABLE INITIALLY DEFERRED auth_user is not filled meaningfully so that I cannot save any information as it crashes when filling the "modified_by" field. Does anyone have a good idea how to solve this problem? I tried changing the ForeignKey to 'self' but this didn't work. Thanks and cheers, Philipp -
Remove Internal Link option
I know this question has been asked before, but the only given solution was hacky and doesn't fully work, at least not with the current version of wagtail. I want to remove the Internal Link option from the page chooser, as for some reason, using the Internal Link just returns "None" meaning it doesn't work. I can link internally manually with the external link option anyway, so I have tried removing it however I can. I have hiding it using CSS and defaulting to external link using JS and hooks, but that doesn't work (any time I create a new link it goes back to defaulting to internal link). I have now also tried replacing wagtailadmin/chooser/_link_types.html by making my own inside templates as the documentation seems to suggest, but that doesn't seem to work either as the old template still seems to be in use... -
How to check if policy ID contains four number exact match in Django
Asking for help on how to detect existing policy that has exact match on filename. Example : GIRL4876S is still passed even though BOY4876T already exists. def policy_exists(policy_id, ref=None): filename = policy_id + '.xml' try: if ref: repo.get_contents('policies/' + filename, ref) else: # no ref default = previous release commit repo.get_contents('policies/' + filename, prev_release_commit()) return True except UnknownObjectException: return False def submit_new(submissions): errors = [] for sub in submissions: if sub.attrib['defect_type'] != 'NV': errors.append('Invalid defect type: ' + sub.attrib['defect_type']) if gh.policy_exists(sub.attrib['policy_id']): errors.append('Existing Policy: ' + sub.attrib['policy_id']) # if sub.attrib['policy_id'].endswith('T'): # errors.append('Terminate policy ' + sub.attrib['policy_id'] + ' is not allowed for this submission type') branch_name = 'NEW-' + ','.join(str(s.attrib['policy_id']) for s in submissions) return branch_name, errors since both GIRL4876S and BOY4876T has 4876 on them. The function should append error. -

Save uploaded InMemoryUploadedFile as tempfile to disk in Django
I'm saving a POST uploaded file to disk by using a technique described here: How to copy InMemoryUploadedFile object to disk from django.core.files.storage import default_storage from django.core.files.base import ContentFile from django.conf import settings data = request.FILES['image'] path = default_storage.save('tmp/%s' % filename, ContentFile(data.read())) tmp_file = os.path.join(settings.MEDIA_ROOT, path) The file does get uploaded and stored at the specified location. However, the content is garbled. It's an image - and when I look at the stored file, I see, the characters are not the same and the image file is damaged. The filesize, however, is the same as the original. I guess, I need to do some conversion before saving the file, but how/which...? -

CSRF Origin check failed Django/Vue.JS
I am currently making a web app that uses Vue.JS for the frontend part and Django for the backend. I'm using django-rest-framework to communicate between the client and the server. I would like to specify that everything works fine when using Postman for testing my requests When trying to login or register (those are only the two features I have implemented yet) The server sends back the following response: "CSRF Failed: Origin checking failed - http://localhost:8080 does not match any trusted origins." Status: 403 The csrftoken cookie is there and I made sure it's sent Here are some details on my setup Requests are sent using Axios. In main.js I overrode the following axios.defaults axios.defaults.baseURL = 'http://localhost:8000'; axios.defaults.xsrfCookieName = 'csrftoken'; axios.defaults.xsrfHeaderName = 'X-CSRFToken'; axios.defaults.withCredentials = true; And the login request is sent in this method in a Pinia user store: async login(email, password) { try { let response = await axios.post('authentication/login/', {email: email, password: password}); this.setUserData(response.data.id, response.data.email); } catch(error) { console.log(error); } }, Server side: My User view is written the following way: def UserAuthenticationView(APIView): serializer_class = UserSerializer def get(self, request): #retrieve currently logged-in user pass def post(self, request): #register new user in database pass @api_view(['POST]) def login(request): # decode … -

django_currentuser alternatives or how to get current user in Models.py
I have 2 Models in my django models.py. I need to get data from model2 to model1, but I don't need to store it anywhere in the model1 fields. I found @property of django and implemented that.

REACT + DJANGO - CORS Errors After Login - CORS header ‘Access-Control-Allow-Origin’ missing
We have a React + Django application on GCP App Engine instances and we are facing a CORS error when fetching data through our REST API. We have already installed and configured the CORS package for the Django Rest Framework in our django application: ` ALLOWED_HOSTS = [ 'xxxxxxxxxxxx.appspot.com', 'yyyyyyyyyyyy.appspot.com', ] CORS_ALLOWED_ORIGINS=[ 'http://localhost:3000', 'https://xxxxxxxxxxxx.appspot.com', 'https://yyyyyyyyyyyy.appspot.com', ] CORS_ALLOW_CREDENTIALS=True ` The preflight request is successful as well as the application login, which performs an async request to our backend: access-control-allow-origin: https://xxxxxxxxxxxxxxxxxxxxx.appspot.com access-control-allow-headers: accept, accept-encoding, authorization, content-type, dnt, origin, user-agent, x-csrftoken, x-requested-with access-control-allow-methods: DELETE, GET, OPTIONS, PATCH, POST, PUT access-control-max-age: 86400 The correct URL is passed through the allow-origins header. The actual GET request is then blocked with a 400 response code from the browser and the following error message: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://xxxxxx.appspot.com/api/entities?page_size=10.

Connect to Postgres on Heroku with Django properly
I'm new to Django and Heroku. I'm confused about how I should connect to Postgres database on Heroku from my Django app considering the fact that all the credentials and DATABASE_URL could be changed. Firstly, to connect to my Postgres on Heroku I started by using environment variables and hardcoded them in my Heroku dashboard. Then I figured out that it is a bad practice because the values can be changed. I checked this guide by Heroku where they recommend adding this to settings: DATABASES['default'] = dj_database_url.config(conn_max_age=600, ssl_require=True) With that, I added my DATABASE_URL to my .env file - because otherwise, the URL will be empty. Now I can get all the correct database credentials in my DATABASE that are the same as in my dashboard. So halfway there. Then I deleted all the hardcoded environment variables from my Heroku dashboard. Then when I tried to heroku run python src/manage.py migrate -a myapp data, I received an error: django.db.utils.OperationalError: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? As I understand it, the problem is that it can't connect to the database (maybe because I deleted … -

My environment is Docker Django PostgreSQL Nginx Gunicorn docker-compose.prod.yml version: '3.8' services: web: build: context: ./app dockerfile: Dockerfile.prod command: gunicorn ecap.wsgi:application --bind 0.0.0.0:8000 volumes: - static_volume:/home/app/web/staticfiles - media_volume:/home/app/web/mediafiles expose: - 8000 env_file: - ./.env.prod depends_on: - db db: image: postgres:13.0-alpine volumes: - db_data:/var/lib/postgresql/data/ env_file: - ./.env.prod.db nginx: build: ./nginx volumes: - ./static_volume:/home/app/web/staticfiles - ./media_volume:/home/app/web/mediafiles ports: - 80 depends_on: - web volumes: db_data: static_volume: media_volume: I assume that the problems is how to write volumes in the yml file. Although I followed the shown way, I cannot keep the data.
