BCS Create Django Site with MySQL Backend

For those times when Django site need to support MySQL this tutorial may be helpful.

The first task is to create the Django project. Go to the command prompt and issue the following command.

django-admin startproject mysite

The result may be observed in the following screen shot.

Next we should allow the MySQL connection.  Firs we need to import the MySQL interface by including the two statements below into settings.py for your project.

import pymysql 
pymysql.install_as_MySQLdb()

Next declare the default database description to point to the correct MySQL database by incorporating the following lines.

'ENGINE': 'django.db.backends.mysql', 
  'NAME': 'pblog', 
  'USER' : 'bcs', 
  'PASSWORD' : 'YourPassword', 
  'HOSTS' : 'localhost', 
  'PORT' : '3306',

After the chages are incorporated the resulting settigs.py file reflects the following.

We should start the server to determine the correctness of our configuration.

python manage.py runserver

Notice the server is running at the prescribed location.

The final step to this portion of the process is to migrate the database by issuing the following command.

python3 manage.py migrate

After the migration is successful you should have similar output messages in your terminal session.

BCS Advantages, Using Anaconda Stack

A primary advantage to using the Anaconda stack for developing Python application is the ease in which the entire stack may be updated. When successfully installed the following script may be used to update the entire stack.

conda update conda
conda update python 
conda update spyder

For windows these command may be inserted in the appropriate .bat file for subsequent execution.
