Guia de Desarrollo Express para Postgresql

Esta es una guia práctica para varios casos de uso común al momento de desarrollar usando postgresql tanto en producción como en desarrollo.

ramses@debian:~$ sudo apt-get install postgresql postgresql-contrib libpq-dev

Here are the steps (for whoever runs into this problem):

For every app, delete its migrations folder: rm -rf <app>/migrations/

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
find . -path "*/migrations/*.pyc"  -delete

Reset the migrations for the "built-in" apps: python manage.py migrate --fake
For each app run: python manage.py makemigrations . Take care of dependencies (models with ForeignKey's should run after their parent model).

We have a simple way

ramses@debian:~ scp /path/to/local/file usuario@servidor:path/to/colocate/the/file

If we need the .pem file We can use this way:

ramses@debian:~ scp -i /path/to/key.pem path/to/local/file usuario@servidor:path/to/colocate/the/file

To access your instance:

Open an SSH client
Locate your private key file (Key-Tesca.pem). The wizard automatically detects the key you used to launch the instance.
Your key must not be publicly viewable for SSH to work. Use this command if needed: chmod 400 Key-Tesca.pem
Connect to your instance using its Public DNS: ec2-123-456-789-123.us-west-2.compute.amazonaws.com

Example: ssh -i "Key-Tesca.pem" [email protected]
