Django Project Tutorial

A step-by-step guide for beginners

Introduction

Welcome to this Django project tutorial! In this tutorial, we will walk you through the process of creating your first Django project.

Prerequisites

Basic understanding of Python
Python installed on your system
Virtual environment setup

Steps

Step 1: Setting Up the Environment

Create a virtual environment and install Django:

python -m venv myenv
source myenv/bin/activate
pip install django

Step 2: Creating a Django Project

Create a new Django project by running:

django-admin startproject myproject

Step 3: Handling File Uploads

Set up your model, form, view, and template to handle file uploads:

1. Set up your model with a FileField:

from django.db import models

class Document(models.Model):
    title = models.CharField(max_length=100)
    uploaded_file = models.FileField(upload_to='documents/')

2. Create a form for file upload:

from django import forms
from .models import Document

class DocumentForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = ('title', 'uploaded_file')

3. Set up your view to handle the form:

from django.shortcuts import render, redirect
from .forms import DocumentForm

def upload_file(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return redirect('success')
    else:
        form = DocumentForm()
    return render(request, 'upload.html', {'form': form})

4. Create a template for the upload form:

<!-- upload.html -->
<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Upload</button>
</form>

Django Problem: Handling User Authentication

One common problem in Django is handling user authentication. Here's a solution to set up user authentication in Django.

Step 1: Setting Up the User Model

Create a custom user model if you need to extend the default user model:

from django.contrib.auth.models import AbstractUser
from django.db import models

class CustomUser(AbstractUser):
    age = models.PositiveIntegerField(null=True, blank=True)

Step 2: Updating settings.py

Update your settings to use the custom user model:

AUTH_USER_MODEL = 'yourapp.CustomUser'

Step 3: Creating User Registration Form

Create a form for user registration:

from django import forms
from django.contrib.auth.forms import UserCreationForm
from .models import CustomUser

class CustomUserCreationForm(UserCreationForm):
    class Meta:
        model = CustomUser
        fields = ('username', 'email', 'age')

Step 4: Setting Up the Registration View

Create a view to handle user registration:

from django.shortcuts import render, redirect
from django.contrib.auth import login
from .forms import CustomUserCreationForm

def register(request):
    if request.method == 'POST':
        form = CustomUserCreationForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            return redirect('home')
    else:
        form = CustomUserCreationForm()
    return render(request, 'register.html', {'form': form})

Step 5: Creating Registration Template

Create a template for user registration:

<!-- register.html -->
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Register</button>
</form>

Conclusion

Congratulations! You have successfully set up your first Django project, handled file uploads, and implemented user authentication. Continue exploring the Django documentation and experiment with different features to deepen your understanding.
