In this Python Django tutorial, we will learn about using the Django display image feature.
Python Django is a free, open-source web framework written in Python. It is based on the model-view-template pattern and operates with the principle of DRY (don't repeat yourself) programming.
It is a stable, mature and well-established framework that has been around for over 10 years. It has a large community of contributors and users around the world who help to improve it continuously.
The following are the steps on how to display an image in Python Django.
The first thing we need to do is create a new file called ‘displayimage.py’ and save it in the ‘static’ folder of your Django project.
Next, we need to import the Image class from the PIL library which is a Python Imaging Library.
Then we create a new instance of the Image class and set its source attribute to point towards our image file.
We then assign this new instance of the Image class to an object called ‘image’ and save it in our variable ‘my_image’.
Finally, we use the my_image object as a source for our HttpResponse object and wrap it inside an HttpResponse.
We need to use the ImageField in the model and then we can use the Django admin to upload an image and then associate that image with a model.
The following code will allow us to display an image from the database in Django:
"""Returns the requested image."""
if request.method == 'POST': # Handle POST requests
if request.FILES['file']: # Handle file uploads
f = open('/path/to/my/image.jpg', 'rb')
image = f.read()
f.close() # Close file when done reading it
