WalkthroughThis pull request introduces a new Docker Compose configuration for a PostgreSQL service, complete with environment variables, volume mapping, and custom port exposure. Additionally, a SQL migration script creates a new database schema with tables for users, polls, user actions, and votes, along with an enumeration for action types. A new migration lock file is added for PostgreSQL, and the Prisma schema is updated to include corresponding models and relationships. Changes

docker-compose.yml (1)
1-19: PostgreSQL Service Configuration: Solid Setup with Minor Suggestions
The docker-compose file defines a PostgreSQL service with the correct environment variables, volume mapping, and port exposure. As a best practice, consider pinning a specific version of the Postgres image (for example,postgres:15.3) rather than usingpostgres:latestto avoid unexpected breaking changes in the future.prisma/schema.prisma (1)
37-52: Model Poll: Comprehensive, Potential for Indexing
ThePollmodel covers a wide range of fields and relationships accurately. For performance optimization, consider adding an index on frequently queried fields such asauthorUserID.prisma/migrations/20250314191236_init/migration.sql (1)
26-42: Poll Table: Detailed Schema with Room for Index Optimization
ThePolltable is comprehensive and aligns with the Prisma model. For improved query performance, you might consider adding an index onauthorUserIDif it becomes a frequent query parameter.

1-3: Migration Lock File: Confirmed Provider Setting
The file correctly specifies the PostgreSQL provider and includes a clear warning not to edit manually. This setup aligns well with the new PostgreSQL service configuration.prisma/schema.prisma (4)
17-26: Model User: Well-Defined Structure
TheUsermodel includes all the necessary fields and relationships. Default values and the one-to-many relations are implemented correctly.
28-35: Model UserAction: Unique and Cascade Configurations
TheUserActionmodel is configured properly with a uniqueactionIDand a cascading delete relation to theUsermodel. This guarantees that orphan records do not persist.
54-63: Model Vote: Correctly Implements Relationships and Constraints
TheVotemodel correctly defines its relationships with both theUserandPollmodels and applies cascading deletes appropriately. If business rules require further validation (for example, onvotingPower), consider adding those constraints at the application level.
65-68: Enum ActionType: Proper Definition
TheActionTypeenum is defined with the required values. It provides clear semantics for actions, aligning well with the application logic.prisma/migrations/20250314191236_init/migration.sql (6)
1-3: Enum Creation for ActionType: Correct Implementation
The creation of theActionTypeenum with values ('CREATED', 'VOTED') is accurate. Note that any future changes to enum values in PostgreSQL require careful handling.
4-14: User Table: Schema Consistency Achieved
TheUsertable schema mirrors the Prisma model well, including default values and the primary key constraint onworldID.
15-25: UserAction Table: Integrity and Uniqueness Ensured
TheUserActiontable is well-defined with its primary key and unique constraint onactionID, supporting the intended data integrity measures.
44-54: Vote Table: Accurate Construction with Cascading Deletes
TheVotetable is accurately constructed with appropriate use of JSONB forweightDistributionand thorough cascading rules to preserve referential integrity.
56-58: Unique Index on UserAction: Correctly Enforced
The unique index onactionIDensures no duplicate user actions can be recorded, solidifying data integrity for theUserActiontable.
59-70: Foreign Key Constraints: Enforcing Referential Integrity
All foreign key constraints are correctly implemented with cascading deletes and updates, ensuring the database maintains consistent and related data across tables.
