Creating a simple Django site with a contact form and saving the received information in the database

I will be using PyCharm Community, you can use your favorite code editor. Activate the virtual environment with the command:

source projectvenv/bin/activate

Install Django:

pip3 install Django

A new Django project is created with the django-admin startproject command (choose your project name yourself):

django-admin startproject projectsite

The application is created with the command python3 manage.py startapp (choose the name of your project yourself):

python3 manage.py startapp mysite

Structure of our project:

Let's start the Django web server:

python3 manage.py runserver

Let's register the newly created application in the project. Let's find the settings.py file in the configuration package, open it in a text editor and find the following code snippet:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mysite', #new app
]

Now let's create our model. Let's open the models.py file and add this code:

from django.db import models


class Task(models.Model):
    title = models.CharField(max_length=50)
    task = models.TextField()

    def __str__(self):
        return self.title


class Note(models.Model):
    title = models.CharField(max_length=50)
    task = models.TextField()

    def __str__(self):
        return self.title


class About(models.Model):
    title = models.CharField(max_length=50)
    task = models.TextField()

    def __str__(self):
        return self.title


class Contact(models.Model):
    email = models.EmailField()
    subject = models.CharField(max_length=255)
    message = models.TextField()

    def __str__(self):
        return self.email

CharField - A string field, for small- to large-sized strings.
TextField - A large text field. The default form widget for this field is a Textarea.
EmailField - A CharField that checks that the value is a valid email address using EmailValidator.

Next, we generate and execute migrations with the commands:

python3 manage.py makemigrations

python3 manage.py migrate

Now we can start using the admin panel. But for this we need a user. You can create it like this: python manage.py createsuperuser. After that, we start the server and we go to http://127.0.0.1:8000/admin/. You will see:

Then, let's open admin.py file of the mysite app and add this code:

from django.contrib import admin
from .models import Task, Note, About, Contact

admin.site.register(Task)
admin.site.register(Note)
admin.site.register(About)
admin.site.register(Contact)

Here's what happens in the end:

Let's create forms.py in mysite application directory:

from django.forms import ModelForm
from .models import Contact


class ContactForm(ModelForm):
    class Meta:
        model = Contact
        fields = '__all__'

Let's open views.py of your mysite app and add this code:

from django.shortcuts import render
from .models import Task, Note, About
from .forms import ContactForm


def index(request):
    tasks = Task.objects.all()
    return render(request, 'index.html', {'tasks': tasks})


def about(request):
    self = About.objects.all()
    return render(request, 'about.html', {'self': self})


def blog(request):
    notes = Note.objects.all()
    return render(request, 'blog.html', {'notes': notes})

def contact_view(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            form.save()
            return render(request, 'success.html')
    form = ContactForm()
    context = {'form': form}
    return render(request, 'contacts.html', context)

Let's create urls.py in mysite application directory:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='home'),
    path('about', views.about, name='about'),
    path('blog', views.blog, name='blog'),
    path('contact', views.contact_view, name='contacts'),
]

Let's open urls.py of projectsite directory and add this code:

from django.contrib import admin
from django.urls import path, include
from mysite import views as contact_views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('mysite.urls')),
    path('contacts/', contact_views.contact_view, name='contacts'),
]

Let's open settings.py and add this code:

import os
...
STATICFILES_DIRS = [
   os.path.join(BASE_DIR, "static"),
]

Let's create a static directory and create a contact.css file in it:

input[type=text], input[type=email], textarea {
 width: 100%;
 padding: 12px 20px;
 margin: 8px 0;
 display: inline-block;
}

Let's create a templates folder, and there we'll create:

base.html

{% load static %}
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">

</head>
