Overview

rails generate graphsql:type Persona

Introspects an already-migrated ActiveRecord model's columns and associations and emits a matching GraphSQL::Mapping type — every column gets a graphsql_column + field pair, every association gets a graphsql_association + field pair (plus a lookahead-driven resolver method for collection associations), and to: is guessed for every non-polymorphic association as "<type_namespace>::Type". Also wires a matching collection field + resolver into the app's query type via Thor's inject_into_class, unless --skip-query.

This only works against a model whose table already exists — it reads real column/association metadata via ActiveRecord, it doesn't infer anything from a migration file. Generate the model (and run its migration) first, then generate its type.
