Django: How to add created_at with nulls for old records?
I'm trying to add created_at field to a table with millions of records, and I don't want to add value to the previous records. I have tried the following: created_at = models.DateTimeField(auto_now_add=True) OR created_at = models.DateTimeField(auto_now_add=True, null=True) Still, it set the value to all records, not only to new ones. How can I keep the old with nulls? My database is postgresql -

Passing variable to href django template
I have some problem and maybe I can give an example of two views below what I want to achieve. class SomeViewOne(TemplateView): model = None template_name = 'app/template1.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # The downloads view contains a list of countries eg France, Poland, Germany # This returns to context and lists these countries in template1 class ItemDetail(TemplateView): model = None template_name = 'app/template2.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) countries_name = kwargs.get('str') The view should get the passed "x" with the name of the country where I described it below. Then on the page I have a list of these countries. After clicking on the selected country, a new tab should open and show a list of cities in the selected country. So I am using in loop template1.html as below {% for x in list_countries %} <li> <a href="{% url 'some-name-url' '{{x}}' %}" class="target='_blank'">{{ x }}</a><br> </li> {% endfor %} I can't pass "x" this way. Why? The url for the next view looks like this path('some/countries/<str:x>/',views.ItemDetail.as_view(), name='some-name-url'), And I can't get that 'x' given in the template in the href -
How to add trix.css when it is removed after pruning?
After pruning with the command "docker system prune -a" nodejs wont build anymore beacuse trix.css is missing. I am assuming this was probably deleted while pruning. How can I resolve this error (see the error below)? Why is it not created again while building the container again since the file is in the docker file.

Translate django admin log entry messages
I've a small django mezzanine application in https://github.com/miettinj/mezzanine It translates admin interface correctly, but it also should translate the page history to understandable form. (I guess it comes directly from django_admin_log in database) Now the admin log looks like this: { "model": "admin.logentry", "pk": 2, "fields": { "action_time": "2022-11-18T08:34:03.136Z", "user": 1, "content_type": 18, "object_id": "1", "object_repr": "janes post", "action_flag": 2, "change_message": "[{\"changed\": {\"fields\": [\"Content\", \"Keywords\"]}}]" } } How can I change it so that it translates the action 'changed', remains the field names unchanged and totally removes the unuserfrienly characters: ("[{\) ? -
Implement HTTP methods in different APIView class in django
I have an API with 2 routes some_resource/ and some_resource/<id> and I would like to implement the normal CRUD actions (list, retrieve, create, update, delete). However, I don't want to use ViewSet because I want to have 1 class for each view. Thus I need to set up the route manually for clarity. : class SomeResourceRetrieveView(APIView): def get(self, request, pk, *args, **kwargs): ... class SomeResourceListView(APIView): def get(self, request, *args, **kwargs): ... class SomeResourceCreateView(APIView): def post(self, request, *args, **kwargs): ... So in urls.py it looks like this url_patterns = [ path("some_resource/", InvitationTeamAccessListAPI.as_view(), name="some-resource-list"), path("some_resource/", InvitationTeamAccessCreateAPI.as_view(), name="some-resource-create"), path("some_resource/<int:pk>", InvitationTeamAccessRetrieveAPI.as_view(), name="some-resource-retrieve"), ] However when I use POST on some_resource/, I get a 405. I think django stops at the first matched route and doesn't find an implementation for post. Is there a way to plug all my views to the same pattern but keep them as separate classes? -
Add angular dist folder to Django project
I am doing the following project: https://github.com/ivandmn/Angular-Django In which I make a simple api with django and use angular as frontend, I have already done the ng build of the angular project where I have the "frontend/static" folder with all the static files. My question is how to add the angular files in django, if someone can explain the structure and the code of how to do it, and then how to manage the angular routes together with the Django ones. PS: I have never put an app into production and it is being very complicated for me, if you can help me I would appreciate it Thank you! -
Getting id number (int) from from a model
I'm working with django and i'm trying to retrieve on id number from my profile model class Profile(Model): user = OneToOneField(User, on_delete=CASCADE) image = ImageField(upload_to='accounts/static/images', blank=True, null=True) gender = CharField(max_length=6, choices=GENDER, default='Male', blank=True) biography = HTMLField(blank=True) def __str__(self): return f"{self.user.username} Profile" and in my views i want to get the @login_required def home(request): return HttpResponseRedirect( reverse('profile_view', args=[request.user.objects.id])) when profile id and user id have the same value, every thing is okay. If i delete a profile and then use this view, the pk's won't match. Hot to 'request' it from the profile for a given user ? As above, but this will not work when user and profile have different pk. -
Why is my docker image not running when using docker run (image), but i can run containers generated by docker-compose up?
My docker-compose creates 3 containers - django, celery and rabbitmq. When i run the following commands -> docker-compose build and docker-compose up, the containers run successfully. However I am having issues with deploying the image. The image generated has an image ID of 24d7638e2aff. For whatever reason however, if I just run the command below, nothing happens with an exit 0. Both the django and celery applications have the same image id. docker run 24d7638e2aff This is not good, as I am unable to deploy this image on kubernetes. My only thought is that the dockerfile has been configured wrongly, but i cannot figure out what is the cause docker-compose.yaml version: "3.9" services: django: container_name: testapp_django build: context: . args: build_env: production ports: - "8000:8000" command: > sh -c "python manage.py migrate && python manage.py runserver 0.0.0.0:8000" volumes: - .:/code links: - rabbitmq - celery rabbitmq: container_name: testapp_rabbitmq restart: always image: rabbitmq:3.10-management ports: - "5672:5672" # specifies port of queue - "15672:15672" # specifies port of management plugin celery: container_name: testapp_celery restart: always build: context: . args: build_env: production command: celery -A testapp worker -l INFO -c 4 depends_on: - rabbitmq Dockerfile ARG PYTHON_VERSION=3.9-slim-buster # define an alias for the … -

I need to make regular working Queue when its not empty in Django
PROJECT: I am making a web app, where users send a ZIP file, it saves to the folder. There is a VM continuously looking for that folder where the zip gets extracted. Note that VM is only 1. So I have to extract, sleep for 20 seconds and remove the files from that folder, VM generates the results, then my Django app generates a CSV from those files, and return to user as downloadable.

How to store mathematical symbols and formulas in column sqlalchemy Postgres as DB
I have two questions: What I want to do is to be able to store a mathematical question with special symbols, formulas that are part of the text. What column should I define in SQLAlchemy so that I can get back the equation without any issue. Second part involves in data entry, I want to upload questions in bulk, now the special symbols cannot be defined/written as text in excel, I was able to do it in MSWord. Is there any specific rules that I can define so I can read the equation in that rule and transform it into mathematical equation. For Ex. similar to latex, if we type [\sqrt{x^2+1}], we see the math format in pdf. That way I can provide a input text where they can write equations in that format and it automatically converts it into math formulae and display it as such. Now is there any intelligent way to achieve this? I'm using Fastapi with SQLAlchemy and for database, I'm using Postgres. If you could point me to relevant resources, that would have great help. -
Django with mysql, faced 'table doesn't exist' error randomly at different times of the day
I'm currently using Django version 2.2.28 with mysql innodb engine version 5.7, before some days i faced a crazy issue, here: (MySQLdb._exceptions.ProgrammingError) (1146, "Table 'db_name.table_name' doesn't exist") What's driving me crazy is that they happen on different tables at different times (not always). I couldn't even get a specific pattern. i can confirm no change in the code happened from along o week and no release happened, The problem started happening 3 days ago and randomly, same table is currently working fine and a minute later the same exception is returned and then back to working fine. i used RDS from AWS, and have different DBs under of it, the issue happening only on one of these DBs. i also checked logs file from mysql and i don't fond any thing useful, i just found errors like this [ERROR] InnoDB: MySQL is freeing a thd though trx->n_mysql_tables_in_use is 2 and trx->mysql_n_tables_locked is 654 and i think it's irrelevant. I make sure about all permissions for the user too. and i did a failover for the whole RDS and nothing working.
