Installing libraries

~$pip3 list 

~$pip3 install djangorestframework --user  

Create and configure Web Application in PythonAnywhere.com

• In Code section, change the following:

  Source code: /home/srikanthtechnologies/website
  Working directory: /home/srikanthtechnologies/
  WSGI configuration file:/var/www/srikanthtechnologies_pythonanywhere_com_wsgi.py
  

• Click on WSGI configuration file and make the following changes:

  
  # +++++++++++ DJANGO +++++++++++
  # To use your own django app use code like this:
  import os
  import sys
  #
  ## assuming your django settings file is at '/home/srikanthtechnologies/mysite/mysite/settings.py'
  ## and your manage.py is at '/home/srikanthtechnologies/mysite/manage.py'
  
  path = '/home/srikanthtechnologies/website' 
  if path not in sys.path:
      sys.path.append(path)
  
  os.environ['DJANGO_SETTINGS_MODULE'] = 'website.settings' 
  #
  ## then:
  from django.core.wsgi import get_wsgi_application
  application = get_wsgi_application()
  

• Go to Static files section and make the following changes:

  URL	        Directory	
  /static/	/home/pragadasrikanth/website/staticfiles        

• Go to top of the page and click on Reload srikanthtechnologies.pythonanywhere.com button.
• Now click on srikanthtechnologies.pythonanywhere.com link provided above Reload button to test your web application. It must be successfully running.
