The `rails generate model` command automates creation of database models, migrations, and tests in Ruby on Rails applications. This guide covers basic syntax for generating models with various field types (string, text, integer, boolean, datetime, decimal, jsonb, references), command modifiers for indexes and constraints, and best practices like using `:references` for foreign keys, `:jsonb` for structured data, and proper enum usage.
