Module: ActiveRecord::Refined::AST::JsonComparable

Included in:
JsonAggregate, JsonBuild, JsonExcept, JsonKeys, JsonPath, JsonSet
Defined in:
lib/active_record/refined/ast.rb

Overview

What a dug value may be compared with. dig_text gives text on every adapter, and what a text value compared with a number means is a question the three answer three ways: dig_text(:n) == 5 is true on SQLite, an error on PostgreSQL and true on MySQL, while dig_text(:flag) == true is true, an error, and false. cast is what says which type was meant, and then all three agree.

dig, bury and except give JSON, and a JSON comparison belongs to the JSON types -- jsonb and MySQL's -- where numbers compare as numbers and documents structurally, key order and spelling aside. The Ruby value goes in as a JSON literal, and the adapters without such a type refuse it from JsonLiteral when the SQL is written, which is when the adapter is known.

A string against dig_text, and anything the block itself built -- a column, a function, another dug value -- go through untouched.

Arithmetic and the bit operators are refused outright on both sides: dig_text(:n) + 1 is 6 on SQLite, an error on PostgreSQL and 6.0 on MariaDB, and an expression on the right does not change what the dug side is.
