About App, Model, and Field Name Length

When deciding the names for your apps, models, or model fields, don't abbreviate, use full words. But keep the length of names no longer than 30 characters. This way you should be safe with database limitations when creating database schema and many-to-many relations.

Database tables and fields are limited to max 63/64 bytes in PostgreSQL/MySQL.
