Aug 28,  · Using media files in Django. Media files are typically managed in Python using FileField and ImageField fields on models.

In a template, you use the url attribute on the file or image field to get a URL for the underlying file. I've found Django's FileField to be really helpful for letting users upload and download files. The Django documentation has a section on managing files.

Build an Instagram clone in Django with user-uploaded files and images. This tutorial shows how to implement file and then image uploading with Django. We'll build a basic Instagram clone. If you're on a Mac the Desktop is a convenient place to put our code. The location doesn't matter; it just needs to be easily available. On the command line, navigate there and create a directory insta for our files.

We will use Pipenv to install both Django and pillow which is a Python image process library Django relies on for image files. For non-image file uploads, pillow is not needed. Finally activate our new virtual environment with the shell command. You should see insta going forward to indicate we're in an active virtual environment. You can type exit at any time to leave it and pipenv shell to re-enter.

Starting with the database model is a good choice. In our case our model Post will only have two fields: title and cover.

We'll set that now. If we wanted to use a regular file here the only difference could be to change ImageField to FileField.

We will add two new configurations. We could pick a name how to download files with django than media here but this is the Django convention. We'll also make an images folder within it to use shortly. Now we can create a superuser account to access the admin and then execute runserver to spin up the local web server for the first time.

It should redirect you to this page:. You can add whatever you like but for this tutorial I'm making a post on the Django Pony mascot. You can download it here yourself if you like. If you look within the local media folder in your project you'll see under images there is now the djangopony. Ok, so at this point we're done with the basics.

But let's take it a step further and display our posts which means urls. The confusing thing about Django is that you often need 4 different but interconnected files for one webpage: models.

Our model is already done so that means diving into URL routes. We'll need two urls. Then define a route for the posts app. Next we'll need to sort out the URL routes within the posts app.

First create that file. Then we'll put all posts on the homepage so again use the empty string '' as our route path. We can use the generic class-based ListView here, import our Post model, and then create a HomePageView that uses the model and a template called home. We have two choices for our template's location. Plus it's harder to reason about templates when they are all buried within their respective apps. So typically I will instead create a project-level templates directory.

Our home. Just like Instagram would :. Ok, that's it! Make sure the server is running with the python manage, how to download files with django. Refresh the page if needed. And voila! If you add additional posts with a title and image via the admin they will appear on the homepage.

Now we can add a form so regular users, who wouldn't have access to the admin, can also add posts. That means creating a new page with a form. Let's start with the views. We can extend Django's built-in ModelForm.

All we need for our basic form is to specify the correct model Post and the fields we want displayed which are title and cover, how to download files with django. And fill it with how to download files with django headline and form. We're specifiying form.

That's it! After you submit a new how to download files with django you'll be redirected back to the homepage and will see all the posts. Hosting this site in production would require a few additional steps. Notably, it's likely that you would use WhiteNoise on the server for your static files, however WhiteNoise explicitly does not support media files.

The common practice is to use django-storages for this purpose and connect to something like S3. What else? You probably want to put restrictions around the image size which can be done initially in the models. Perhaps you want to add edit and delete options as well for the Post, how to download files with django. And you'll likely want a thumbnail version of the images too which can be done with sorl-thumbnail.
