Yediemin

A package for bulletproof attachment serving in Django Rest Framework.

Getting Started

Requirements

• Nginx
• Django Rest Framework
• Session Authentication
• Django Storages (S3)

Installation Steps

1. Install package from PyPi.

pip install yediemin

2. Add the view to urls.py

from yediemin import YedieminView

urlpatterns = [
    re_path(r'^yediemin/(?P<file_name>\S+)/$', YedieminView.as_view(), name='yediemin'),
]

3. Configure Nginx. Place the configuration below under your server.

location /yediemin-files/ {
            internal;
            resolver 8.8.8.8;
            set $redirect_uri "$upstream_http_redirect_uri";

            proxy_buffering off;
            proxy_pass $redirect_uri;
}

4. Use YedieminFileField in serializer for FileField.

from yediemin import YedieminFileField

class AttachmentSerializer(serializers.ModelSerializer):
    file = YedieminFileField()

    class Meta:
        model = Attachment
        fields = (
            "id",
            "file",
        )

5. Use PrivateS3Boto3Storage for the field in models.py

from yediemin import PrivateS3Boto3Storage

class Attachment(models.Model):
    file = models.FileField(storage=PrivateS3Boto3Storage())

6. Upload files to S3 with YedieminFileField. Yediemin requires presigned object url.
