Hi, everyone.
I need to add one more column to ActiveScaffold via association, but here
is problem: the same column already exists with the same association
Env Rails 2.1.1, ActiveScaffold for Rails 2.1
Basical model
class Context < ActiveRecord::Base
has_many :descendant_associations, :class_name => 'ContextsRelation',
:foreign_key => 'ancestor_context_id'
has_many :descendant_contexts, :through => :descendant_associations,
:source => :context, :uniq => true
named_scope :countries, lambda {|*args|
self.options_for_contexts_filter(COUNTRIES_CONTEXT, args.first == :wi ?
:country : nil)}
named_scope :regions, lambda
{self.options_for_contexts_filter(REGIONS_CONTEXT)}
end
And AS controller:
class Manage::CountryContextsController < ManageAreaController
active_scaffold :context do |config|
config.columns[:descendant_contexts].label = 'Countries'
config.columns[:descendant_contexts].sort_by :method =>
"descendant_contexts.cities.sorted.collect{ |v| v.name }.join(', ')"
config.columns[:descendant_contexts].label = 'Regions'
config.columns[:descendant_contexts].sort_by :method =>
"descendant_contexts.regions.sorted.collect{ |v| v.name }.join(', ')"
end
end
How to resolve this issue? I have no idea. For any idea or approaches will
be very appreciated.
