*Course 401 Python, Entry 26: Django

What are the key components of the Django framework, and how do they contribute to building a web application?

• Defined models, which allows for SQL creation if needed.
• Clean URLS creation. Unlike PHP for example, it allows for clean URL mapping with different renderings.
• A template language which is easy to use due to its similarities to HTML. Additionally, extendible in functionality.
• Forms which cleanly integrate with Python.

---

• Full-featured authentication: permissions and cookie-based sessions.
• Automatic admin interface. Allows for content creators to plug in. Built off of metadata in models.

Explain the role of Django’s MTV (Model-View-Template) architecture and how it handles a typical web request-response cycle.

• The HTTP request comes in and is handled by the URL mapper.
• The mapper then directs the request to the appropriate View.
• The View (a request handler function) handles the request.
• The data required to fulfill the request is met via the appopriate model.
• Content is returned via the appropriate template (HTML, JSON, etc.).

What is the purpose of Tailwind CSS, and how does it differ from Bootstrap CSS?

It is a framework for quickly writing web code without using custom CSS. Tailwind uses utility classes. This allows for a lot of CSS to be pumped into a HTML tag via a class attribute. The difference is that unlike Bootstrap where components are used, in Tailwind, pre-build CSS classes are used instead which then can be further tweaked. This vastly reduced CSS. It also allows for more flexibility. Outcome, a more unique site appearance.

Summary: Tailwind is Bootstrap, but more flexible.

Things I want to know more about

What are the limits of Views. Can this be used to plug into other APIs or networks?
