Bootcamp: Instalación en windows

Este error se produce cuando django == 2.0, en este momento Bootcamp no es compatible con esa versión de Django. Elimínelo e instale una versión anterior, django == 1.11.x funciona correctamente.

Buenos días @ sebastian-code,

He degradado el django, pero ahora tengo este error:

Hola @ Allan-Nava, parece que tienes problemas con tu base de datos y el servidor no puede establecer conexión con el volumen de datos, ¿cómo estás haciendo esa parte?

Hola @ sebastian-code, es mi primera aplicación de Django con Windows para mi pc personal. ¿Qué tengo que hacer?

Depende de cómo trabajes con las bases de datos. Personalmente, uso Docker, pero podría usar una instancia local de PostgreSQL, tal vez montar un servidor de base de datos en red o una máquina virtual de algún tipo. También existe la opción más fácil que usar SQLite localmente.

Quiero intentar usar SQLite localmente

Para eso, defina la variable DATABASE_URL dentro de su archivo .env con una dirección de base de datos SQLite formateada correctamente utilizando el formato URL. Puede encontrar un ejemplo dentro del archivo env.example .

Yo uso el .env con la misma configuración:

# PostgreSQL conf
# POSTGRES_PASSWORD=mysecretpass
# POSTGRES_USER=my_super_user
# POSTGRES_DB=bootcamp
# DATABASE_URL=postgresql://my_super_user:[email protected]:5432/bootcamp

# Main environmental variables
DEBUG=True
SECRET_KEY=s3cr3t_key
ALLOWED_HOSTS=*
# URL to have SQLite example and to pass TravisCI
DATABASE_URL=sqlite:////bootcamp/db.sqlite3
# URL for Redis
# REDIS_URL=redis://redis_ip_address:port

Yo tengo el mismo error:

C:\Users\allan\Documents\progetti\bootcamp>python manage.py migrate

Eso se debe a que la dirección es incorrecta. Para SQLite, Django requiere la ubicación física del archivo SQLite dentro de su disco duro, expresada en formato URI.

@ sebastian-code ¡Gracias, funciona!

@ sebastian-code Tengo django 2.x en caché de pip. Ahora, ¿cómo puedo forzar a pip a usar django 1.9 mientras ejecuto este comando? pip install -U -r requirements/local.txt

Hola @jackengine La forma más fácil es ejecutar el comando, y una vez instalado, eliminar manualmente el paquete y luego instalar django nuevamente, pero declarando la versión específica que deseas. Mi consejo sería no seguir con django v1.9, es demasiado antiguo, sugeriría usar django 1.11 que es LTS.
