Getting Docker-Compose file working on ubuntu
I have a django project running correctly with docker compose on my mac, but I want to get the docker-compose working on my linux ubuntu machine. When I run the docker-compose file on my mac everything works fine; however, I run into an issue on ubuntu where it says that port 5432 is in use. This is because: "On your Mac, you can run PostgreSQL on the host machine and use the same port (5432) without conflict because Docker for Mac uses a feature called "host networking" by default. With host networking, containers share the network stack with the host machine, allowing them to access services running on the host directly. In the case of your Docker Compose file, when you run it on your Mac with PostgreSQL running on the host on port 5432, the container can still access the PostgreSQL service on the host because it shares the network stack. The container's PostgreSQL service listens on the same port inside the container (5432) as the host's PostgreSQL service. So, when your Django application inside the container tries to connect to the database at localhost:5432, it effectively connects to the PostgreSQL service running on the host." So I modify … -
how to shrink my celery-worker docker image?
I am running Django application on ECS and I am trying to optimize the size of Docker containers. Below are my Dockerfiles that I am using to build django-app, celery-worker and celery-beat services on ECS. CMD are inserted in ECS task definition. The problem I have is that the size of celery worker container exceeds 1 GB and with enabled autoscalig it takes around 5 minutes to create new task in ECS service, to build and deploy the container. It is not a problen when deploying whole application but it is probmematic when I want to autoscale my app and I need to wait 5 minutes for new task so celery can run another tasks. Concurrency is set up to 3 and I cannot put higher number because my tasks are heavy and last around an hour (each). How can I optimize the size of celery Dockerfile and the way in is being built and deployed on ECS?

HTMX tags not activating when using locally-stored copy of source code in Django project
I have a Django project where I'm using HTMX to set up "cascading" SELECT widgets (i.e. the options listed in SELECT #2 are modified based on the user option from SELECT #1). I've confirmed that the HTMX tags in SELECT #1 are triggering as expected when I put this line in the HTML template header to pull in the HTMX code from their web site: <script src="https://unpkg.com/htmx.org@1.9.2" integrity="sha384-L6OqL9pRWyyFU3+/bjdSri+iIphTN/bvYyM37tICVyOJkWZLpP2vGn6VUEXgzg6h" crossorigin="anonymous"></script> Specifically, I can confirm the event is triggering because at this point the corresponding view for the target (create_itemid_2) is just a stub, and I see the printed message in my Powershell console. def create_itemid_2(request): print('HTMX event fired') context = {} return render(request,'create_itemid_2.html',context) So now I want to pull down the code, and use it locally in my Django project, so I'm not dependent on the external resource. The problem is, after I've done that, the event never triggers. I can even see the js file being successfully retrieved in my console (HTTP status 200, then 304 after that), but still the event never triggers.

How to optimize the filtering of queryset in ModelViewSet

django only show the highest value of m2m in template
Hej! I have a table view with multiple columns one of them contains a m2m field from the model. I dont want all values (if multiple values/entries are given for that m2m) only the highest.

Save Django attachments from a form
Good morning, I would greatly appreciate your help, I am starting to use Django and I am making a web application that allows workers in a job to attach their documentation (files) through a form. The problem is that at the moment of pressing the submit of the form with the attached files, these are not saved, however, the name and other fields of the Charfield type are saved correctly. The only way to save the files is to attach them from the admin portal, but the idea is that each user enters from a url generated with their id that will be sent by email. Also, the files should be saved with the naming (DSR_”rut”-”name”-”filename (form label)”-0-”extension), but I still can't configure the naming of the file name instance. file, according to the label of the form. models.py: class Candidato(models.Model): nombre = models.CharField(max_length = 70, null=True, blank=True) rut = models.CharField(max_length = 10, primary_key=True) correo = models.EmailField(null=True, blank=True) centro_de_costo =models.CharField(null=True, blank=True, max_length =30, choices = cc) estado = models.IntegerField(null=True, blank=True) imagen = models.ImageField(upload_to=upload_directory_name, null=True, blank=True) certificado_antecedentes = models.FileField(upload_to=upload_directory_name, null=True, blank=True) hoja_de_vida_conductor = models.FileField(upload_to=upload_directory_name, null=True, blank=True) certificado_residencia = models.FileField(upload_to=upload_directory_name, null=True, blank=True) certificado_afiliacion_afp = models.FileField(upload_to=upload_directory_name, null=True, blank=True) certificado_afiliacion_salud = models.FileField(upload_to=upload_directory_name, null=True, blank=True) … -
