Using the knowledge of the python training create a project.

This project is based on a diagram made in class and my choice was a Shop system (POS) and if there is time to continue to start on making the start of administrations modules trying to throw high to get a close start on a ERP.

The shop will be base on this module at first glance and it will be modified:

Setting Up Containers for Django Project

1. Build DB container: >docker-compose build db
2. Bring DB container up: >docker-compose up db
   1. Set DB container to run on background: >docker-compose up -d db
3. Build MIGRATIONS container: >docker-compose build migration
4. Build WEB container: >docker-compose build web
5. Create a Django Project: >docker-compose run web django-admin startproject my_web
6. Setup DB connection on settings.py file
7. Run MIGRATIONS container to create db >docker-compose up migration
8. Run Web container to check if settings and db are working: >docker-compose up web
9. Create a Super User for Admin: >docker-compose run web python manage.py createsuperuser

Helpfull Commands

1. Create migrations for a specific app: >docker-compose run migration python manage.py makemigrations <APP_NAME>

1. Build Docker Image: >docker-compose build

2. Run Dokcer DB First to avoid problems with Django Web app running first: >docker-compose up -d db

3. Run Docker Migrations if they exist: >docker-compose build migration

4. Run Docker Web app: >docker-compose up -d web

5. Otherwise you could just run: >docker-compose up or >docker-compose up -d

6. Change Settings file on the main project:

   TEMPLATE_DIR = os.path.join(BASE_DIR,'templates')
   

7. Edit ALLOWED_HOSTS, DATABASES and TEMPLATES like the next code:

   ALLOWED_HOSTS = [
       '*'
   ]
   TEMPLATES = [
       {
           'BACKEND': 'django.template.backends.django.DjangoTemplates',
           'DIRS': [TEMPLATE_DIR,],
           'APP_DIRS': True,
           'OPTIONS': {
               'context_processors': [
                   'django.template.context_processors.debug',
                   'django.template.context_processors.request',
                   'django.contrib.auth.context_processors.auth',
                   'django.contrib.messages.context_processors.messages',
               ],
           },
       },
   ]
   
   DATABASES = {
       'default': {
           'ENGINE': 'django.db.backends.postgresql',
           'NAME': 'postgres',
           'USER': 'postgres',
           'PASSWORD': 'db_password',
           'HOST': 'db', 
           'PORT': 5432,
       }
   } 
   

8. Next Server should be running on local on port 8000:

   0.0.0.0:8000
   127.0.0.1:8000
   localhost:8000
