Django getting values from postgres jsonb field
I have a simple model like: class MyModel(models.Model): data = JSONField() The JSONField data is in the following structure: { "name": "Brian", "skills": [ {"id": 4, "name": "First aid"}, {"id": 5, "name": "Second aid"} ] } I'd like to create a query that gets a list of MyModels filtered by the id of the skill inside the data. I've tried a few different avenues here, and can do the work in Python but I'm pretty sure there's a way to do this in Django; I think my SQL isn't good enough to figure it out. Cheers in advance. -
How to get a list of all attributes in model -Django Rest Framework
I am trying to get a list of all names,emails and phones without writing similar class with get() method for each of them. Is there a way to write one general class for this purpose?I used APIView and Serializer(instead of ModelSerializer) consciously. Here is my code. views.py class userInfoList(APIView): def get(self, request, format=None): users = userInfo.objects.all() serializer = userInfoSerializer(users, many=True) return Response(serializer.data) serializers.py from phonenumber_field.serializerfields import PhoneNumberField from rest_framework import serializers from .models import userInfo class userInfoSerializer(serializers.Serializer): id = serializers.IntegerField(read_only=True) name = serializers.CharField(max_length=50) email = serializers.EmailField(max_length=70) phone = PhoneNumberField() def create(self, validated_data): return userInfo.objects.create(**validated_data) def update(self, instance, validated_data): instance.name = validated_data.get('name', instance.name) instance.email = validated_data.get('email', instance.email) instance.phone = validated_data.get('phone', instance.phone) instance.save() return instance -

How to browse files on a boto3 space ? NoSuchKey error
I created a s3 space with Digitalocean. I upload files into this one with ckeditor in a django project. I have no problem for uploading files but I meet a problem when I try to browse my server (to see if an image is already present) Here is my code: session = boto3.session.Session() client = session.client('s3', region_name='fra1', endpoint_url=settings.AWS_S3_ENDPOINT_URL, aws_access_key_id=settings.AWS_ACCESS_KEY_ID, aws_secret_access_key=settings.AWS_SECRET_ACCESS_KEY ) resp = client.list_objects(Bucket=settings.AWS_STORAGE_BUCKET_NAME) And an error happend the line where I call the function list_objects An error occurred (NoSuchKey) when calling the ListObjects operation: Unknown That's really stranger because I'm sure my settings.AWS_STORAGE_BUCKET_NAME is the correct one. Furthermore I'm sure there is no error in session.client because I use the same for uploading files, which works perfectly. To make sure my bucket is the correct one I go to my AWS_S3_ENDPOINT_URL and got an XML with <ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <Name>[MY BUCKET NAME]</Name> <Prefix/> <MaxKeys>1000</MaxKeys> <IsTruncated>false</IsTruncated> And after that begins a list of <Contents> Thank you for your help -

Django behind Nginx build_absolute_uri returns http://host/
Django's request.build_absolute_uri() function returns http://host/ for my URL pointing to / on localhost and any domain I host it on. Django is behind Nginx and both are docker containers. Here's a docker-compose.yml: version: '2.4' services: django: build: context: . env_file: ./.env volumes: - ./src:/django_project nginx: image: nginx volumes: - ./nginx.conf:/tmp/nginx.conf depends_on: - django links: - django ports: - "3000:80" Django is behind Nginx and the Nginx config is as follows: server { listen 80; client_max_body_size 80M; location / { proxy_pass http://django:8000/; proxy_read_timeout 240s; uwsgi_ignore_client_abort on; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; } } I'm thinking it's definitely Nginx that's the bad gue, but what am I missing? -

Celery & Celery Beat daemons not running tasks
I've set up the celeryd and celerybeat daemon by following this guide. When the daemons start, everything is marked as ok, however Celery simply doesn't run any of the tasks set in my Django application. This is my /etc/default/celeryd file: CELERY_NODES="w1" CELERY_BIN="/home/millez/myproject/venv/bin/celery" CELERY_CHDIR="/home/millez/myproject" CELERY_OPTS="-l info --pool=solo" CELERYD_LOG_FILE="/var/log/celery/%n%I.log" CELERYD_PID_FILE="/var/run/celery/%n.pid" CELERY_CREATE_DIRS=1 and this is my /etc/default/celerybeat: CELERY_BIN="/home/millez/myproject/venv/bin/celery" CELERYBEAT_CHDIR="/home/millez/myproject" CELERYBEAT_OPTS="--schedule=/var/run/celery/celerybeat-schedule" If I manually restart the daemons, (sudo /etc/init.d/celeryd restart and sudo /etc/init.d/celerybeat restart), and then check their statuses, this is the only output I get: celeryd (node celery) (pid 2493) is up... Running the actual celery commands manually works fine, e.g celery -A myproject worker -l info, it seems to be an issue with the way I've set up the daemons. However, I'm not too Linux savvy, so if anyone happens to be able to see some easy oversight I've made, let me know, this is driving me insane. -

Django Invalid credentials while loggin into the account
I'm trying from a few days to create a login & register system for my WebSite, built with Django. But, every time I try to login to my superuser account, or a testaccount that I've created, I get an error. When I enter my credentials in the form and press the Submit button, the page reloads but I am not logged in as a user and no error is given to me. But if I go to the admin page, i'll see an error saying me that Username or Password is invalid. I set this error to make it appear on the login page when the credentials were wrong, but nevertheless, despite the credentials are right, I am given a mistake, and moreover on the wrong page.

How to implement autocomplete user search in React and Django Rest Framework
So basically I'd like to implement a user search system in react which would send an api request to my django backend which would send back the results. This is an easy implementation if I wanted the results once I hit search but I want the results displayed as autocompletes. For example in Twitter it autocompletes what you are searching for. How would I implement this. I am using axios for my requests if that helps. A side note would be that I'd like to wait maybe a second or 2 before sending the request because I would want to send to many requests and slow down the server. Thank you! -
Display User's 'is_active' status in TabularInline Django
I have a Client object that has a User and a Company objects as FKs class Client(models.Model): user = models.OneToOneField(User) company = models.ForeignKey(Company, blank=True, null=True) In my CompanyAdmin, I want a list of all clients as a TabularInline, including the active status of each client (based on user object) class CompanyClients(admin.TabularInline): model = Client fields = ('user', 'master') class CompanyAdmin(admin.ModelAdmin): inlines = [CompanyClients] I want to add a column in my TabularInline to indicate that that user is active or not. I tried using 'user__is_active' to my fields but I get this error: Unknown field(s) (user__is_active) specified for Client I just want an indication even if read-only (which I tried by putting a readonly_fields and it didn't work too), not looking to save/edit each client user's active status value from the Tabular form. How can I approach this? Thanks in advance. -

Means whenever I define a foreign-key field in model, i would need nothing more to make it autocomplete.

But in contrast with django when i define a filed on child_model1 like parent_id = models.ForeignKey(ParentModel1) First i would need to define on_delete=?, even I have no option to set anywhere globally that hello django please always restrict on delete until I tell you to make a field on_delete=cascade Then I need that all of my foreign-key fields in any model need to be autocomplete but I always have to write each field in each each child model's admin like autocomplete_fields = ['parent_id'] also I have to give something like search_fields … -
How to use Cross Site Request Forgery protection correctly?
I've only started getting into web programming with Django recently. In order to make my website more secure, I used csrf_token when sending POST request, followed what I saw in https://docs.djangoproject.com/en/3.1/ref/csrf/.
