Django is a popular web framework of Python for Web developers. It is used for Backend work. We can create a large project using the Django framework. Most companies like Instagram, Spotify, Mozilla, Pinterest, Disqus, etc are using Django for their Backend. It helps to create a Complex website.
In this post, I will create a File Share Website using the Django framework.
Let's Go.
Our Project structure:-
Follow these steps to create & configure our project:-
Step 1 - Create a project using this command ( django-admin startproject filesharing )
Step 2 - Go inside to our project and create an app in this project ( python manage.py startapp main )
Step 3 - Open project's settings.py file and add the main app in INSTALLED_APPS section.
Step 4 - Create an urls.py file in our main app and add it to project's urls.py file , like this
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('main.urls'))
]
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [BASE_DIR/'templates'], # add here
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
Step 6 - Create a User and File_Upload models in models.py file
from django.db import models
# Create your models here.
class User(models.Model):
name = models.CharField(max_length=50)
email = models.EmailField()
pwd = models.CharField(max_length=100)
gender = models.CharField(max_length=20)
def __str__(self):
return self.name
class File_Upload(models.Model):
user = models.ForeignKey(User, models.CASCADE)
title = models.CharField(max_length=50)
description = models.TextField()
file_field = models.FileField(upload_to="")
def __str__(self):
return self.title
Step 7 - Register these models in admin.py file
from django.contrib import admin
from .models import User, File_Upload
# Register your models here.
admin.site.register(User)
admin.site.register(File_Upload)
Step 8 - Now let's create our super user using this command ( python manage.py createsuperuser ). It will ask you Username, Email, Password.
Step 9 - Code in views.py file
from django.shortcuts import render, redirect
from .models import User, File_Upload
from django.contrib import messages
# Create your views here.
def index(request):
if 'user' in request.session:
all_files = File_Upload.objects.all()
data = {'files': all_files}
return render(request, 'index.html', data)
else:
return redirect('login')
def login(request):
if 'user' not in request.session:
if request.method == 'POST':
email = request.POST['email']
pwd = request.POST['pwd']
userExists = User.objects.filter(email=email, pwd=pwd)
if userExists.exists():
request.session["user"] = email
return redirect('index')
else:
messages.warning(request, "Wrong user or details.")
return render(request, 'login.html')
else:
return redirect('index')
def logout(request):
del request.session['user']
return redirect('login')
def signup(request):
if request.method == 'POST':
name = request.POST['name']
email = request.POST['email']
pwd = request.POST['pwd']
gender = request.POST['gender']
if not User.objects.filter(email=email).exists():
create_user = User.objects.create(name=name, email=email, pwd=pwd,
gender=gender)
create_user.save()
messages.success(request, "Your account is created successfully!")
return redirect('login')
else:
messages.warning(request, "Email is already registered!")
return render(request, 'signup.html')
def settings(request):
if 'user' in request.session:
user_obj = User.objects.get(email = request.session['user'])
user_files = File_Upload.objects.filter(user = user_obj)
img_list = []
audio_list = []
videos_list = []
pdfs_list = []
for file in user_files:
if str(file.file_field)[-3:] == 'mp3':
audio_list.append(file)
elif str(file.file_field)[-3:] == 'mp4' or
str(file.file_field)[-3:] == 'mkv':
videos_list.append(file)
elif str(file.file_field)[-3:] == 'jpg' or
str(file.file_field)[-3:] == 'png' or
str(file.file_field)[-3:] == 'jpeg':
img_list.append(file)
elif str(file.file_field)[-3:] == 'pdf':
pdfs_list.append(file)
data = {'user_files': user_files, 'videos': len(videos_list),
'audios': len(audio_list), 'images': len(img_list),
'pdf': len(pdfs_list), 'img_list': img_list,
'audio_list': audio_list, 'videos_list': videos_list,
'pdfs_list': pdfs_list}
return render(request, 'settings.html', data)
def file_upload(request):
if request.method == 'POST':
title_name = request.POST['title']
description_name = request.POST['description']
file_name = request.FILES['file_to_upload']
user_obj = User.objects.get(email=request.session['user'])
new_file = File_Upload.objects.create(user = user_obj, title=title_name,
description=description_name, file_field = file_name)
messages.success(request, "File is uploaded successfully!")
new_file.save()
return render(request, 'file_upload.html')
def delete_file(request, id):
if 'user' in request.session:
file_obj = File_Upload.objects.get(id = id)
file_obj.delete()
return redirect('settings')
else:
return redirect('login')
Step 10 - Create some path in urls.py file in main app.
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name="index"),
path('login/', views.login, name="login"),
path('logout/', views.logout, name="logout"),
path('signup/', views.signup, name="signup"),
path('settings/', views.settings, name="settings"),
path("file_upload/", views.file_upload, name="file_upload"),
path('delete/<str:id>/', views.delete_file, name="delete_file")
]
Step 11 - Add some html files in Template folder
File 1- base.html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

Step 12 - For successful file uploadation we have to add some important lines in settings.py & urls.py.
# In setting.py file
STATIC_URL = 'static/'
STATICFILES_DIRS = [BASE_DIR/'static']
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR/'static'/'media'
# In urls.py file
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('main.urls'))
]
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
Our project is created succesfully. Now lets start our server using this command -
python manage.py runserver
Thanks for reading my blog. You can read my others post too. I hope you get some knowledgeable stuff.
bro pls give a searchbar code
