function number_format(amount, decimals) {

    amount += ''; // por si pasan un numero en vez de un string
    amount = parseFloat(amount.replace(/[^0-9\.]/g, '')); // elimino cualquier cosa que no sea numero o punto

    decimals = decimals || 0; // por si la variable no fue fue pasada

    // si no es un numero o es igual a cero retorno el mismo cero

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

To use the most modern version of Postgres software we need to add postgresql repository. Edit /etc/apt/sources.list or create /etc/apt/sources.list.d/pgdg.list and add there a line: deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main Then import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Install a new version of PostgreSQL server.

Once the Debian upgrade finished, I used dpkg-query -l postgresql* to check which versions of postgres I have installed.

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

1. Empty the django_migrations: table: delete from django_migrations;
2. 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
   

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

How to send a file from local to remote server

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
