Module: ActiveScaffold::DataStructures::ActionColumns::AfterConfiguration
- Defined in:
- lib/active_scaffold/data_structures/action_columns.rb
Overview
A package of stuff to add after the configuration block. This is an attempt at making a certain level of functionality inaccessible during configuration, to reduce possible breakage from misuse. The bulk of the package is a means of connecting the referential column set (ActionColumns) with the actual column objects (Columns). This lets us iterate over the set and yield real column objects.

Redefine the each method to yield actual Column objects.

#each(options = {}, &proc) ⇒ Object
Redefine the each method to yield actual Column objects. It will skip constrained and unauthorized columns.
Options:
* :flatten - whether to recursively iterate on nested sets. default is false.
* :for - the record (or class) being iterated over. used for column-level security. default is the class.
