In order to making changes to Celery (if there are any) you need to remove all volumes associated with worker service

docker compose down --volumes

coverage run --source='.' manage.py test --no-input && coverage html && coverage report --skip-covered

./db.vuerd.json

celery -A main worker --beat -l info

upgrade postgres in docker compose https://betterprogramming.pub/how-to-upgrade-your-postgresql-version-using-docker-d1e81dbbbdf9

docker-compose exec {service_name} pg_dumpall -U {postgres_user} > dump.sql

Connect to the container's bash terminal

docker-compose exec {service_name} bash

Now we run the import command

psql -U {postgres_user} -d {default_postgres_database} < {mapped_volume_folder_path}/dump.sql

We may encounter this error

User "postgres" does not have a valid SCRAM secret.

resetting the password for the "postgres" user using the following command:

docker-compose exec db psql -U postgres -c "ALTER USER postgres WITH PASSWORD 'new_password';"

Export requirement.txt

poetry export --without-hashes -f requirements.txt --output requirements.txt

worker:
    build: .
    command: watchmedo auto-restart --recursive -p '*.py' -- python -m celery -A main worker --beat -l info
    environment:
      - REDIS_CACHING_HOST=cache
      - REDIS_CACHING_PORT=${REDIS_CACHING_PORT}
    volumes:
      - .:/code
    depends_on:
      - cache

The environment variables declared in the docker-compose.yml file will override the values specified in the .env file. -> in the updated configuration, the environment variables REDIS_CACHING_HOST=cache and REDIS_CACHING_PORT=6379 will take precedence over the values specified in the .env file.

Regarding the connectivity issue, when you run your application locally on your host machine, services like Redis or PostgreSQL typically run on 127.0.0.1 (localhost) because they are running directly on your host machine. However, within a Docker network created by Docker Compose, each service gets its own isolated network stack, and the service names can be used as hostnames to communicate between services.

In the case of this worker service, it is running within the Docker network created by Docker Compose, and the Redis service is also running within the same network. So, the worker service can access the Redis service using the service name "cache" as the hostname because Docker Compose sets up internal DNS resolution for service names.

-> In the worker service configuration, specifying REDIS_CACHING_HOST=cache means that the worker will connect to the Redis service using the hostname "cache" within the Docker network, rather than trying to connect to 127.0.0.1, which would refer to the worker container itself.

First time run:

./manage.py makemessages -l vi
./manage.py makemessages -l en

This project support multiple language using i18n Everywhen there are new updates in models -> Things to do:

• Define a verbose_name and verbose_name_plural in new model's Meta.

class newModel(ModelBase):
    class Meta:
        db_table = 'backend_new_model'
        ordering = ['pk']
        verbose_name = _('new model')
        verbose_name_plural = _('new models')

• Define a verbose_name in new model's fields

new_field = models.CharField(max_length=256, verbose_name=_('new field'))

verbose_name and verbose_name plural should be in lowercase for consistency and separator '_' should be replaced by ' ' (space)

• Update .po files

django-admin makemessages --all

• Provide the corresponding translation to the defined verbose_name model and fields by editting .po files

vdbc.be
└── locale
    └── <language> # ex: vi, en ...
        └── LC_MESSAGES
            └── django.po

• Upload the .po file to https://poeditor.com/ or edit the .po file with the following syntax

#: backend/models/<new_model>.py:11
msgid <verbose_name> #"city"
msgstr <translation> #"thành phố"

• Generate .mo files

django-admin compilemessages
