Tutoring centers: asset library using Django

Summary

A asset library blueprint for tutoring centers built with Django on Ample. Domain schema:

• course_groups (subject, level, start_at, end_at, capacity): tutoring groups;
• memberships (course_group_id, student_reference, guardian_reference, role): students, guardians and tutors;
• sessions (course_group_id, starts_at, tutor, attendance_count): session events;
• materials (course_group_id, title, object_key, visibility): worksheets and answer keys;
• uploads (id, owner_reference, object_key, content_type, size, uploaded_at): validated uploads linked to their owner.

Public information: subjects and levels, schedule and locations, tutor qualifications. Kept out of scope until handling is reviewed: minor students and guardian identity, progress reports. Data about minors is sensitive; only group schedules and materials are modeled here.

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).

Representative Queries

• Tutoring centers: asset library using Django
• Where can I host Tutoring centers: Asset library built with Django?
• I need a genuinely specialized asset library workflow covering course-group membership, session events and teaching materials.

Resource Requirements

• primitive:compute
• primitive:postgres
• primitive:s3-compatible-object-storage

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.

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 tutoring centers data classes may be handled at all; this blueprint models public information only.

Examples

Django pattern fixture

• Verified browser file uploads basis for this blueprint.

Workflow Steps

1. Model the tutoring centers domain: Create the tables course_groups, memberships, sessions, materials, uploads. Tutoring groups lives in course_groups; keep the sensitive classes (minor students and guardian identity, progress reports) 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.
7. Verify: Run the pattern self-test(s) from the example (/p/browser-file-uploads) and your own acceptance checks for the tutoring centers workflow.

Success Checks

• app responds on its public URL
• browser-file-uploads self-test from the example

Limitations

• No health, financial, privacy or other compliance claim is made. Data about minors is sensitive; only group schedules and materials are modeled here.
• Verified on the python-3.12 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.

Cost Estimate

• Monthly Amount: 10 USD
  • App Server: 5.0
  • Managed PostgreSQL Database: 5.0

Note

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