* Add project specs, gitignore the source PDF
specs/batch-cooking-architecture.md and specs/batch-cooking-modele.md
are the clean markdown transcription of "Projet batch cooking.pdf"
(a scanned/image-only PDF, no extractable text). The PDF itself is
gitignored — source working document, not meant to be committed.
* Add Prisma schema for the documented data model
Models every table from specs/batch-cooking-modele.md: users/household
(user_profiles, house, diet, allergy, category), planning (planning,
planning_item), and recipes (recipe, ingredients, step, tech_step,
tech_step_mapping, sources).
Two deliberate deviations from the literal spec doc, per project
discussion:
- recipe_ingredient (recipe <-> ingredients) carries quantity + unit.
The spec describes a plain many-to-many with no extra fields, but a
shopping list / batch-cooking calculation needs quantities.
- step is modeled one-to-many from recipe (not many-to-many as labeled
in the doc): the documented `order` column only makes sense scoped
to a single recipe, which isn't reconcilable with steps being
shared across recipes.
Everything else follows the doc as-is, including field nullability
choices made where the doc doesn't specify (e.g. user_profiles.house_id
optional, recipe.source_id optional) and onDelete behavior (Cascade
for owned child records, SetNull for optional references) — first
draft, not meant as final production hardening.
Verified: `prisma validate`, `prisma generate`, and a real
`prisma migrate dev` against a local Postgres (via docker-compose) —
the migration applies cleanly and produces the expected schema.
README: documents the migrate command and a Postgres port-conflict
gotcha hit during validation (a native Postgres service on this
machine was already bound to 5432, intercepting the Docker container's
connections).
* Add COMMENT ON for every table and column in the init migration
Descriptions pulled from specs/batch-cooking-modele.md's per-table
field tables. The two tables not in the original spec (join tables
recipe_ingredient, user_profile_allergy) get a comment explaining
why they exist.
Amends the still-unmerged init migration directly rather than adding
a follow-up migration, since it hasn't been applied anywhere but this
local dev database.
Verified: `prisma migrate reset --force` reapplies cleanly, and a
query against pg_description confirms every column of every project
table has a comment (only Prisma's own internal _prisma_migrations
table is uncommented, out of scope).
