Q5.) How do you check for the version of Django installed on your system?

To check for the version of Django installed on your system, you can open the command prompt and enter the following command:

• python -m django –version

You can also try to import Django and use the get_version() method as follows:

import django

print(django.get_version())

Q6.) Explain Django architecture.

Django follows the MVT or Model View Template architecture whcih is based on the MVC or Model View Controller architecture. The main difference between these two is that Django itself takes care of the controller part.

According to Django, the ‘view’ basically describes the data presented to the user. It does not deal with how the data looks but rather what the data actually is. Views are basically callback functions for the specified URL’s and these callback functions describe which data is presented.

The ‘templates’ on the other hand deal with the presentation of data, thereby, separating the content from its presentation. In Django, views delegate to the templates to present the data.

The ‘controller’ here is Django itself which sends the request to the appropriate view in accordance with the specified URL. This is why Django is referred to as MTV rather than MVC architecture.

Q7.) What are Django’s templates?

Django templates render information in a designer-friendly format to present to the user. Using the Django Template Language (DTL), a user can generate HTML dynamically. Django templates consist of simple text files that can create any text-based format such as XML, CSV, and HTML.

Q8.) Discuss Django’s Request/Response Cycle.

Starting the process off, the Django server receives a request. The server then looks for a matching URL in the URL patterns defined for the project. If the server can’t find a matching URL, it produces a 404-status code. If the URL matches, it executes the corresponding code in the view file associated with the URL and sends a response.

Q9.) Briefly explain Django Field Class.

‘Field’ is basically an abstract class that actually represents a column in the database table. The Field class, is in turn, a subclass of  RegisterLookupMixin. In Django, these fields are used to create database tables (db_type()) which are used to map Python types to the database using get_prep_value() and vice versa using from_db_value() method. Therefore, fields are fundamental pieces in different Django APIs such as models and querysets.

Q10.) How to do you create a Django project?

To create a Django project, cd into the directory where you would like to create your project and type the following command:

• django-admin startproject xyz

NOTE: Here, xyz is the name of the project. You can give any name that you desire.
