7. How does Django architecture work?

Django follows the MVT or Model View Template engineering which depends on the MVC or Model View Controller design. The fundamental distinction between these two is that Django itself deals with the regulator part. 

As per Django, the 'view' essentially depicts the information introduced to the client. It doesn't manage how the information looks but instead what the information really is. Perspectives are fundamentally callback capacities for the predefined URLs and these callback capacities portray which information is introduced. 

The 'templates' then again manage the introduction of information, accordingly, isolating the substance from its introduction. In Django, sees representative to the formats to introduce the information. 

The 'controller' here is Django itself which sends the solicitation to the proper view as per the predetermined URL. This is the reason Django is alluded to as MTV as opposed to MVC design.

8. Give a brief about ‘Django-admin’.

  3. python sqlmigrate <name of the app followed by the generated id> (sqlmigrate takes the migration names and returns their SQL)
