From d4d5269b74e4fc04062169746b5803c88f8d43b0 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 13:30:51 +0000 Subject: [PATCH 1/2] feat: Add comparison operators for number field queries Implement support for querying number fields with comparison operators, following Laravel Eloquent and Active Record patterns. Features: - Three-parameter syntax: where('age', '>', 18) - Supported operators: =, !=, <>, >, >=, <, <= - Maps to MongoDB operators: $gt, $gte, $lt, $lte, $ne - Maintains backward compatibility with 2-param syntax - Full test coverage for all operators Example usage: ```typescript // Greater than User.where('age', '>', 35).get() // Less than or equal User.where('price', '<=', 50).get() // Chaining User.where('age', '>', 18) .where('votes', '<=', 100) .get() ``` Resolves #57 --- packages/esix/src/base-model.spec.ts | 249 +++++++++++++++++++++++++++ packages/esix/src/base-model.ts | 30
