Host csv import tool with Django: file attachments

Deploy a csv import tool built with Django on Ample using the browser file uploads pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL, a private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables. 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). Not separately tested: your upload UI, allowed types, size limits and virus scanning; treat the csv import tool-specific behavior as your application code.

Representative Queries

• Host csv import tool with Django: file attachments
• Where can I host CSV import tool built with Django?
• I need a restricted upload flow, file validation and record-to-object linkage.

Resource Requirements

• Primitive Compute
• Primitive Postgres
• Primitive S3-compatible Object Storage

Infrastructure Requirements

• Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
• Postgres: 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: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Support Status

Execution Status

Ready

Prerequisites

• A Django project that builds and starts with the documented commands (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 at runtime (auto-provisioned when omitted, or supplied with --env)
• A bucket from ample bucket create with its credentials passed as encrypted S3_* environment variables
• An Ample account token with servers:write, databases:read, buckets:read

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

Input Schema

• Properties:
  • env: Encrypted environment variables (bucket credentials, secrets)
  • name: App name
  • path: Project directory or ample.toml service
  • release_command: Migration command run before activation
  • start: Start command (Python apps pass one explicitly)
• Required: env, name, path, start

Workflow Steps

1. Build and start: pip install into .ample/python from requirements.txt, then waitress serving project.wsgi from run.py reading PORT on the python-3.12 template. The server must bind 0.0.0.0 on PORT.
2. Implement the pattern on PostgreSQL: The fixture's module implements browser file uploads: content-type and size validation that rejects disallowed files.
3. Wire object storage: Create the bucket(s), then pass endpoint, region, bucket and keys as --env values.
4. Deploy: Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked).
5. Verify: Fetch the live URL and the pattern self-test route(s).

Examples

• Django pattern fixture: Multi-pattern Django app whose browser file uploads module was checked live; the module is under tests/deploy-canaries/_pattern-modules.

Cost Estimate

• Currency: USD
• Monthly Amount: 10.0
• Components:
  • App server: s-1vcpu-1gb
  • Managed PostgreSQL database: s-1vcpu-1gb
• Note: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle.

Limitations

• Verified on the python-3.12 template; other sizes and Django major versions are not verified.
• The csv import tool itself is application code and was not separately tested.
• Region, compliance attestations and request-duration limits are unknown and not claimed.

Evidence Summary

• Canary Run: Django pattern fixture deployed on Ample.
• Last Verified At: 2026-09-20T03:31:44Z

Unknowns

• Region availability is unknown until a verified region fact is recorded.
