This initialization lets the database know that it is okay for the media field to be null if the user entering the data simply doesn't have any media to attach. Media is an instance of a FileField which was initialized with the null argument set to True.
Media = models.FileField(null= True, blank= True)Įach beast has a name, description, accompanying media (sightings of the beast) as well as a mom_classification (M.O.M stands for Ministry of Magic). Mom_classification = models.CharField(max_length= 5, choices=MOM_CLASSIFICATIONS) ( 'XXX', 'Competent wizard should cope'), In the beasts/models.py file, we can define a model that extends the models.Model class, which then inherits the functionality to be saved in the database: from django.db import models A form can then be created to represent a blank slate of this model, allowing the user to fill in the details. Let's start off by defining a model of a Beast, which directly matches to a database table.
Uploading Files with Django Creating the Model We can define a simple model for a Beast, create a form and template to display it to an end user, as well as handle the files they send through with the form. Once a project skeleton has been created, we can move into that directory and start the app via startapp: $ django-admin startproject fantasticbeasts $ cd fantasticbeasts $ django-admin startapp beastsĪnd finally, let's register this app in the fantasticbeasts/settings.py file, by adding it to the list of INSTALLED_APPS: INSTALLED_APPS = [Īwesome! Now we are all set. Now, let's create a project, named fantasticbeasts via the startproject command of the django-admin module.
#Django file upload example install#
Here, we can install Django via pip: $ pip install "Django=3.0.*" Once the environment is activated, if we install dependencies, they'll only be applicable to that environment, and won't collide with other environments, or even the system environment.

Now that our virtual environment has been created, all that's is left to do is to activate it, by running the activate script: # Windows $ myenv/Scripts/activate.bat # Linux $ source myenv/Scripts/activate # MacOS $ source env/bin/activate Open your command prompt/shell and inside the directory we've just created, run: $ mkdir fileupload $ cd fileupload $ python -m venv. Let's create a directory that will act as a container for the environment. This step is optional, but highly recommended, and considered good practice for keeping Python environments clean. We start by creating a virtual environment to avoid having our dependencies cause version mismatch issues with other projects. Throughout this guide, we'll assume basic knowledge of Django and quickly go through the setup process, though, if you'd like to gain deeper understanding of the project creation process, read our Guide to Creating a REST API in Python with Django! If you're unfamiliar with Django and its modules, such as django-admin - you can read out general guide to creating REST APIs that cover the basic elements of Django. We will create a form through which they can log descriptions and images for each beast, then we will render that form, store the information and display it to the user when needed. Let's assume we live in an imaginary universe where we live alongside the magical creatures of the Harry Potter books, and the magi-zoologists of our world need an application to keep track of information regarding each magical creature they study. We will be building a small project where we can implement file upload, storage, and display functionalities of Django, with a database, however, storing the images on a hard drive. Throughout the guide, we'll be taking these questions into consideration, building a small project that offers a user the ability to upload files to a Django web application. Uploading files also raises a question of storage (where the files end up) as well as display (how they can be retrieved and displayed).
#Django file upload example how to#
In this guide, we'll take a look at how to upload a file with Python, to a Django-based web application.įiles that are uploaded can be additionally processed in various forms, or could be left in their raw state. Users are so used to file sharing within a wide variety of software, that its novelty is far-gone, and its functionality is oftentimes considered standard. This data can take various forms and shapes, and some common human-interpretable format are images, videos, and audio files. The World Wide Web facilitated the transfer of huge amounts of data between networked computers, and it's a community that creates and shares data in abundance.
