Photography studios: asset library using Django

Summary

A asset library blueprint for photography studios built with Django on Ample. Domain schema: listings (reference, session_type, price_from, publishing_status, agency_id): session packages with publishing status; agencies (name, location, studio_count): studios or locations; galleries (listing_id, object_key, cdn_key, consent_reference): published portfolio media; reports (agency_id, period, object_key, generated_at): studio booking reports; uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner. Public information: session packages and pricing from, consented portfolio galleries, studio locations. Kept out of scope until handling is reviewed: client galleries before release, minors in photographs, payment details. Client galleries are private until released with consent; only consented portfolio media is public. Technical basis verified on Django: content-type and size validation that rejects disallowed files, an object written to a private bucket and a row linking the record to the object key (reject=ok upload=ok linked=ok).

Infrastructure requirements

• Compute: verified (Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.)
• Postgres: verified (Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.)
• S3-compatible object storage: verified (Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.)

Prerequisites

• A Django project (pip install into .ample/python from requirements.txt, then waitress serving project.wsgi from run.py reading PORT on the python-3.12 template)
• A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
• Bucket credentials from ample bucket create passed as encrypted S3_* environment variables
• A review of which photography studios data classes may be handled at all; this blueprint models public information only

Exact tested configuration

• template: python-3.12
• runtime: python
• size: s-1vcpu-1gb
• install: python3 -m pip install --target .ample/python -r requirements.txt
• start: PYTHONPATH=.ample/python:${PYTHONPATH:-} python3 run.py

Steps

1. Model the photography studios domain. Create the tables listings, agencies, galleries, reports, uploads. Session packages with publishing status lives in listings; keep the sensitive classes (client galleries before release, minors in photographs, payment details) out of this schema.
2. Workflow step 1. Model assets linked to their owning group or workspace
3. Workflow step 2. Validate uploads and store them in the private bucket; link each object to its row
4. Workflow step 3. Authorize downloads by membership
5. Workflow step 4. Deploy and verify rejection of disallowed files and a linked upload
6. Deploy. Run the synchronous deploy once and read the result. Re-running with no change is a no-op.

   ample deploy . --name <app-name> --public --start "python3 run.py" --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...

7. Verify. Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the photography studios workflow.

Tested examples

• Django pattern fixture (tests/deploy-canaries/django-patterns): Verified browser file uploads basis for this blueprint.

Success checks

• app responds on its public URL (/ on the live URL, expect ample canary django patterns)
• browser-file-uploads self-test from the example (/p/browser-file-uploads on the live URL, expect see the pattern fixture checks)

Limitations

• The technical basis (browser file uploads on Django) was verified with the pattern fixture; the photography studios schema and workflow are an original design for this blueprint and were not executed as a separate application.
• No health, financial, privacy or other compliance claim is made. Client galleries are private until released with consent; only consented portfolio media is public.
• Public content and synthetic examples only until actual data-handling requirements have been reviewed.
• Verified on the python-3.12 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
• Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
• PutObject and GetObject with path-style addressing are verified; other S3 operations and CDN cache rules are not verified.

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

• app server x1 s-1vcpu-1gb: 5.00 USD
• managed PostgreSQL database x1 s-1vcpu-1gb: 5.00 USD

Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

The blueprint's Photography studios schema and workflow below build on that verified basis and were not separately executed. (expires 2027-03-19T03:31:44Z)
