Module: ActiveScaffold::AttributeParams

Defined in:

lib/active_scaffold/attribute_params.rb

Overview

Provides support for param hashes assumed to be model attributes. Support is primarily needed for creating/editing associated records using a nested hash structure.

Paradigm Params Hash (should write unit tests on this):

params[:record] = {
  # a simple record attribute
  'name' => 'John',
  # a plural association hash
  'roles' => {
    # hack to be able to clear roles
    '0' => ''
    # associate with an existing role
    '5' => {'id' => 5}
    # associate with an existing role and edit it
    '6' => {'id' => 6, 'name' => 'designer'}
    # create and associate a new role
    '124521' => {'name' => 'marketer'}
  }
  # a singular association hash
  'location' => {'id' => 12, 'city' => 'New York'}
}

Simpler association structures are also supported, like:

params[:record] = {
  # a simple record attribute
  'name' => 'John',
  # a plural association ... all ids refer to existing records
  'roles' => ['5', '6'],
  # a singular association ... all ids refer to existing records
  'location' => '12'
