internals

Overview ¶

Example: internals

Shows what drel's codegen produces under the hood. Everything here — ModelMeta, Scan, Snapshot, Diff, column references — is normally generated into <model>_drel.go files. This example hand-crafts them so you can see the machinery without running the code generator.

Covers: queries (Find, Where, OrderBy, Limit, OR, Count, Exists, string Contains) AND transactions (insert, update with change tracking, delete, rollback, mid-tx SaveChanges).

Usage:

export DATABASE_URL="postgres://localhost:5432/drelexample?sslmode=disable"
go run ./examples/internals/
