For this part of tutorial we are going to be building A simple Django Booking(appointment) App!

Welcome Back!

Let's get started.

Start by creating a project called appointment
Also create a app called app
Register your app in your project folder
And do your url config.

Pls Get the template folder we are going to be using fromLink to my Github Profile

Let's Get Started!

Template and Static files Settings.

Step 1: after setting up your django application we will register our template files

Step 2: Static Files

Urls and Views

I hope you have already set up your urls if you haven't set it up to see if you can do it if you encounter any error pls comment in the comment section!

Let's get started!

1 models.py:

What is models.py:
Models.py is a file that allows us to completely define our database!

2 views.py:

What is context in our views.py:
So we imported our models in line 2 of our code and we want to show something from our database so we use context manager to help us render models to view!

3 urls.py:

What did we do in urls.py?:
We imported our views file and used it to create our url

4 admin.py:

What just happened in the file:
we imported our model and register it so it can be viewed in the admin site

*Introduction to Django Admin Site *
What is Django admin?
Django Has a built-in admin site that handles the site management and to log in to the admin site we need to create a superuser to do that we use this command python manage.py createsuperuser it will throw an error because you haven't make your migrations
to do that we use this command python manage.py makemigrations the command will initialize your database and then this command python manage.py migrateto create the necessary tables and columns then you can crate your super user

now crate your superuser and runserver then go to /admin

you will discover a page saying login so you enter your superuser credentials and boom a dashboard

Add some models and play around with it
Pls Comment if you encounter any errors

Play Around With this Part 4 will contain user authentication and sending mails i hope we all have a great understanding of django

Welcome Back to part 2 of this tutorial I hope we all have a great understanding on Django.

We will continue from where we stopped in the last tutorial if you are just joining please checkout part1 of this tutorial part1 of this tutorial

Let's get started!

What is views in Django?

A view is simple python function that takes a request and return a http response, the response can either be in html, 404, xml, etc.

What is Urls in Django?
A urls is a web address e.g(www.example.com) that uses your view to know what to show the user on a web page

Note: Before you can start with your views you have to create a urls.py file in your application folder like this below

App Forlder Structure:

app/
    __init__.py
    admin.py
    apps.py
    migrations/
        __init__.py
    models.py
    tests.py
    views.py
    urls.py

Writing our first view
app/views.py

from django.shortcuts import render
from django.http import HttpResponse
def home(request):
    return HttpResponse("<h1>A simple views!</h1>")

Setting up our urls
first we have to configure our urls.py in our project folder
project/urls.py

from django.contrib import admin
from django.urls import path, include # so we can include our app urls


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('app.urls')), #here

]

Then
app/urls.py

from django.urls import path
from . import views # importing the view

urlpatterns = [
    path('', views.home, name="home"),
]

A simple view and url config

We will Look at templates and static directory/files in the next tutorial
