Using Django to retrieve data from a file uploaded through a website

Looking to create a website that allows users to select a local file (XML/JSON) and then navigate to a Django view to extract data from it. Should I implement javascript for the file selection form and sending it to a specific URL for the Django view? Any guidance on how to achieve this? Are there any examples available?

I found a starting point here.

Whether you prefer to include javascript in your project or not, the Django functionality remains constant. Your application will have a Django view responsible for handling file uploads. If you are using the

<input type="file" name="" />

element, you can retrieve the file using the request.FILES object. Detailed information can be found in the documentation here.

This snippet demonstrates how your view could manage the uploaded file:

def file_upload_view(request):
    file_name = request.FILES['input_field_name'].name 
    file_data = request.FILES['input_field_name'].read()
    # process the file here

When providing users with the option to upload files, you can either allow them to submit the form normally or utilize javascript to send the file via AJAX. For AJAX uploads, consider using a jQuery plugin like jquery-iframe-transport. However, it might be simpler to stick with traditional form submission.
