Content Disposition

A library that allows easy management of 'Content-Disposition' details of HTTP responses.

So far it provides:

• RFC 5987 (file response, https://datatracker.ietf.org/doc/html/rfc5987)

Installation

1. Install using pip:

pip install content-disposition

Usage

Use the rfc5987_content_disposition function to set an HTTP response's 'Content-Type' field in any endpoint, e.g.:

# within views.py

from django.http import FileResponse
from rest_framework import viewsets
from rest_framework.decorators import action

from content_disposition import rfc5987_content_disposition

class MyViewSet(viewsets.ModelViewSet):
    ...

    @action(
        detail=True,
        methods="get",
        url_path=r"download",
    )
    def download_route(self, request, pk=None):
        """
        Assuming that self.get_object() returns a model defining
        'name = models.CharField(...)', 'file = models.FileField(...)' and 'mime = models.CharField(...)'
        whereas 'mime' represents the correct mime_type related to 'file'
        """
        instance = self.get_object()

        response = FileResponse(
            instance.file,
            content_type=instance.mime,
        )
        response["Content-Disposition"] = rfc5987_content_disposition(instance.name)

        return response
    ...
