Setting Up the Project

Before we get started, make sure you have Django installed. If not, install it using pip:

pip install django

Next, create a new Django project and app:

django-admin startproject multi_file_upload_project
cd multi_file_upload_project
django-admin startapp file_uploads

Models and Database Setup

Let’s create a simple model to represent the uploaded files in this example. Inside the models.py file of the file_uploads app, add the following:

from django.db import models

class UploadedFile(models.Model):
    file = models.FileField(upload_to='uploads/')
    uploaded_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.file.name

Make sure to run the migrations to create the necessary database table:

python manage.py makemigrations
python manage.py migrate

Creating the Upload Form

Now, let’s create a form to handle the file uploads. In the forms.py file of the file_uploads app, add the following code:

from django import forms
from .models import UploadedFile

class FileUploadForm(forms.ModelForm):
    class Meta:
        model = UploadedFile
        fields = ('file',)

Uploading Files in Views

In the views.py file of the file_uploads app, we’ll define a view to handle file uploads:

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

def upload_files(request):
    if request.method == 'POST':
        form = FileUploadForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return redirect('success')  # Replace 'success' with the name of your success page URL
    else:
        form = FileUploadForm()
    return render(request, 'upload.html', {'form': form})

Frontend: Creating the Upload Form Template

In the templates folder of the file_uploads app, create a new file called upload.html and add the following:

<!DOCTYPE html>
<html>
<head>
    <title>File Upload</title>
</head>
<body>
    <h2>Upload Files</h2>
    <form method="post" enctype="multipart/form-data">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Upload</button>
    </form>
</body>
</html>

URL Configuration

Let’s define the URL configuration to wire up the view and template. In the urls.py file of the file_uploads app, add the following:

from django.urls import path
from . import views

urlpatterns = [
    path('upload/', views.upload_files, name='upload'),
    # Add any other URLs you may need
]

Next, include the app URLs in the main project’s urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('file_uploads/', include('file_uploads.urls')),
    # Add other app URLs here if needed
]

Handling Uploaded Files

The uploaded files are now stored in the ‘uploads/’ directory within your media root. Don’t forget to configure your media settings in settings.py:

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

Conclusion

Congratulations! You’ve successfully implemented multi-file uploads in Django. Users can now upload multiple files, and you can access these files using the UploadedFile model. Django’s built-in features make this process a breeze, allowing you to focus on building other parts of your web application.

Remember to handle file validation, security, and other considerations in a real-world application.

Remember to replace your_success_page with the URL of the page you want to redirect users after a successful file upload.
