SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the creation of well-structured, validated database models, ensuring data integrity and consistency from the very beginning of development.

Core Features & Use Cases

  • Data Integrity: Defines ORM models with clear naming, proper data types, relationships, and constraints.
  • Automated Validation: Implements model-level validations, timestamps, and indexing for optimal performance.
  • Use Case: Automatically generate a new Product model with fields like name, description, price, and category_id, including validation rules and a foreign key relationship.

Quick Start

Use the backend models skill to define a new 'Order' model with fields for 'customer_id', 'total_amount', and 'status', including appropriate data types and relationships.

FAQPage Schema
How do I define ORM models with proper relationships and constraints?▼

ORM models should include clear field definitions with appropriate data types, foreign key relationships (has-many, belongs-to, many-to-many), and database constraints like NOT NULL and UNIQUE. Add timestamps, indexes, and cascade rules to maintain data integrity across your schema.

What's the best way to prevent data integrity issues in my database models?▼

Standardize ORM model definitions by enforcing consistent naming, proper relationships, field validation at the model level, and appropriate indexing. Include computed properties, scopes, and cascade rules to ensure reliable schemas across your codebase.

How do I add validation and indexing to database models?▼

Implement model-level validations, timestamps, and strategic indexing within your ORM classes. Define constraints at the database level and use computed properties or scopes to optimize query performance and ensure data consistency.

Can I automate the creation of new database models with relationships?▼

Yes. Generate standardized ORM models with field definitions, foreign key relationships, validation rules, and database constraints automatically. This ensures consistent structure and prevents common data integrity issues from the start.

What database constraints should I include in entity definitions?▼

Include NOT NULL, UNIQUE, and foreign key constraints in your entity definitions. Add cascade rules for relationship integrity, indexes for query optimization, and timestamps for audit trails and data tracking.

Do I need to define indexes and cascade rules in my ORM models?▼

Yes. Define indexes to optimize query performance and cascade rules to maintain referential integrity when records are updated or deleted. Both are essential for reliable, performant database schemas in production.
