What is the difference between django.db.backends.dummy and django.db.backends.mysql?

django.db.backends.mysql

used when the database is backend MySQL

.

This is determined by the database parameters Engine

ENGINE = `django.db.backends.postgresql_psycopg2`

      

        
        
        
      

    

If as, is django.db.backends.dummy

not a per-word setting, but starts with

ENGINE = '' # The default setting for ENGINE

      

        
        
        
      

    

Besides,

Digging into the source code fordjango.db.backends.dummy

,

Django uses this if the database DATA parameter is empty (None or empty string).

It also dummy

raises an error:

                           "Please supply the ENGINE value. Check "
                           "settings documentation for more details.")
