Instance Method Details

#storable_by(column, keys = {}, prefix: nil, suffix: nil, **kw_keys) ⇒ Object

Declare typed accessors over ‘column`. Key specs may arrive as the positional `keys` Hash or as trailing keyword arguments (they are merged); the positional form is the escape hatch for keys literally named `prefix`/`suffix`. See the module docs.

def storable_by(column, keys = {}, prefix: nil, suffix: nil, **kw_keys)
  column = column.to_sym
  ensure_columns!(LABEL, column)

  prepared = storable_merge_key_specs(keys, kw_keys).map do |key, raw_spec|
    key = key.to_sym
    [key, storable_normalize_spec(key, raw_spec, prefix, suffix)]
  end

  storable_install_keys(column, prepared)
end

#storable_native_hash_column?(column) ⇒ Boolean

Lazily decide — once per class/column, at first write when a DB connection exists — whether the column’s attribute type stores a Hash natively (a :json column, or a host-app ‘serialize`d column) so we can hand it the Hash; everything else gets a generated JSON String.

Returns:

  • (Boolean)
