Basic aspects about Django REST Framework:

• Serialization.
• Requests & Responses.
• Class-based views.
• Authentication & permissions.
• Relationships & hyperlinked APIs.
• Viewsets & routers.
• Schemas & client libraries.

1. Donwload Python 3 from https://www.python.org/downloads/.
2. Install Pip with this link: https://pip.pypa.io/en/stable/installing/ , if you don't know if you have pip, type this command

# Verify pip
$ pip -V

Once you have pip installed, update pip with this command

# Update pip
$ pip install -U pip

3. Download or clone this repository in your folder

# Clone this repository
$ git clone https://github.com/luisfelipe7/Learning-Django-REST-Framework

4. Go into the repository

# Go into the repository
$ cd Learning-Django-REST-Framework

5. Create a virtual environment

# Install virtualenv 
$ sudo pip install virtualenv 

# Create a virtual environment with Python3, env is the name of the environment
$ virtualenv env --python=python3 

# Activate your environment
$ cd env
$ source bin/activate 

6. With the activated environment, install the requirements:

# Install requirements
$ pip install -r requirements.txt

7. Run it.

1. Install Postgresql

# Install postgresql
$ sudo apt-get install postgresql

2. Connecting to PostgreSQL for first time
   
   a) Run the psql command from the postgres user account

# Enter with the user postgres
$ sudo -u postgres psql postgres

       b) Set the password

# Enter this command for set the password
$ \password postgres

       c) Enter a password
       d) Close psql

# Close psql
$ \q

3. Create a new user and database
   
   a) Enter to Postgresql

# Enter with the user postgres
$ su - postgres  

       b) Create the new user and database

postgres=# CREATE USER admin WITH PASSWORD 'admin';
postgres=# CREATE DATABASE mydatabase OWNER admin;

4. Configure your database, paste in settings.py file of your Django project the next configuration:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mydatabase',
        'USER': 'admin',
        'PASSWORD': 'admin',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

5. Allow local connections, edit the file pg_hba.conf (/etc/postgresql/9.6/main/pg_hba.conf) as a superuser and replace the final lines of the file with these lines:

# Database administrative login by Unix domain socket
local   all             postgres                                md5

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                peer
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

6. Sync your models

# Apply Migrations
$ python manage.py migrate

7. Create a superuser for admin views

# Create a superuser
$ python manage.py createsuperuser

8. Run your development server

# Run a development server

How to install and use Pgadmin :

1. First, Pgadmin require Flask, so we need to install it with pip:

# Install flask
$ pip install flask

2. Donwload the Pgadmin from the next url ( I don't recommend to download the last version, because it have some bugs ) : https://www.postgresql.org/ftp/pgadmin/pgadmin4/
3. According to the dowloaded file, install it with the next command:

# Install Pgadmin
$ pip install pgadmin4-3.2-py2.py3-none-any.whl

4. For run it use this command:

# Python Version - pgAdmin4.py file
$ sudo python3.5  "/home/felipe/Escritorio/Solvo/Documentacion Tecnica/Proyectos/Entornos Virtuales/env2/lib/python3.5/site-packages/pgadmin4/pgAdmin4.py"

5. Configure it for your local databases, click on create server and follow these images:
