Working of the MVT:

Here, a user requests for a resource to the Django, Django works as a controller and check to the available resource in URL.

If URL maps, a view is called that interact with model and template, it renders a template.

Django responds back to the user and sends a template as a response.

Basic environment settings

conda create -n django_traversy python=3.9.7 conda activate django_traversy pip install Django==3.2.7

for creating the project

python manage.py startproject studybud

for creating the apps

python manage.py startapp base

add the installed app to the django project

go to > studybud\studybud\settings.py > INSTALLED_APPS > add this >>'base.apps.BaseConfig' class

For adding templates to the project

go to > studybud\studybud\settings.py and add the following to DIR[] BASEDIR / "templates"

26/1/2022:> https://www.youtube.com/watch?v=PtQiiknWUcI&t=2395s

include a template into different templates

{% include 'navbar.html'%}

for extending the template

navbar.html ---> main.html (include) || VV home.html / room.html (extending the main.html template functionality)

inside main.html file

    {% include 'navbar.html' %}
    {% block content %}
    {% endblock %}

inside home.html file

{% extends 'main.html'%}

{% block content %}
<h1>room</h1>

{% endblock %}

Main template restructuring done at: https://youtu.be/PtQiiknWUcI?t=3509

• All the app(base) specific templates are under: * Explring_django-> studybud-> base-> templates-> base-> home.html/room.html
• and all the main templates are under root template folder: * Explring_django-> studybud-> templates-> main.html/navbar.html

Dynamic URL routing at https://youtu.be/PtQiiknWUcI?t=3555

example: path('room/str:pk',views.room,name='room')

here str:pk will give the following patterns like "room/1" , "room/2" etc

Dynamic URL naming at https://youtu.be/PtQiiknWUcI?t=3767 (URL Patterns)

in the below code: path('room/str:pk',views.room,name='room')

"name" parameter's value can be used instead of 'room/0' for dynamic routing within the different templates.

This "name" parameter is beneficial when we want to change the name of the url on a large project. so we don't have to change the url in each and every codebase. Since all the code will reference the same "name" parameter value.

{% url room room.id%} from template  === room/1 in the URL rendering
