Instance Method Details

#finder(column_name) ⇒ Object

Each call adds one indexed column that gets a ‘where_<col>` finder method on the generated model class. Spinel-shape constraint: each finder is its own typed method, single arity —we don’t generate a dynamic ‘where(hash)` because hash dispatch widens to RbVal.

# File 'lib/fresco/model_builder.rb', line 40

def finder(column_name)
  @finders << column_name
end

#validates(column_name, **opts) ⇒ Object

M4 validations DSL. Currently supports ‘validates :col, presence: true` — emitted as a top-of-method early-return guard inside insert/update. All validation is pure-Ruby (no DB roundtrip); rules expand to monomorphic `==` / `.length` checks so Spinel doesn’t widen the param types.
