  • Q23.

    Django is based on which design pattern.

    Posted by Sharad Jaiswal

    Django closely follows the MVC (Model View Controller) design pattern, however, it does use its own logic in the implementation. Because the “C” is handled by the framework itself and most of the excitement in Django happens in models, templates, and views, Django is often referred to as an MTV framework. In the MTV development pattern:

    • M stands for “Model,” the data access layer. This layer contains anything and everything about the data: how to access it, how to validate it, which behaviors it has, and the relationships between the data.
    • T stands for “Template,” the presentation layer. This layer contains presentation-related decisions: how something should be displayed on a Web page or other type of document.
    • V stands for “View,” the business logic layer. This layer contains the logic that accesses the model and defers to the appropriate template(s). You can think of it as the bridge between models and templates.

    How a request is processed in Django?

    Posted by Sharad Jaiswal

    In Django whenever a request is made by a user, it goes through the following steps:

    • Django determines the root URLconf module to use. Ordinarily, this is the value of the ROOT_URLCONF setting, but if the incoming HttpRequest object has a urlconf attribute (set by middleware), its value will be used in place of the ROOT_URLCONF setting.
    • Django loads that Python module and looks for the variable urlpatterns. This should be a Python list of django.urls.path() and/or django.urls.re_path() instances.
    • Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL.
    • Once one of the URL patterns matches, Django imports and calls the given view, which is a simple Python function (or a class-based view). The view gets passed the following arguments:
      • An instance of HttpRequest.
      • If the matched URL pattern returned no named groups, then the matches from the regular expression are provided as positional arguments.
      • The keyword arguments are made up of any named parts matched by the path expression, overridden by any arguments specified in the optional kwargs argument to django.urls.path() or django.urls.re_path().
      • If no URL pattern matches, or if an exception is raised during any point in this process, Django invokes an appropriate error-handling view.
  • Q31.

    When to use the iterator in Django ORM?
