Hello Rails experts,

Need your help in following issue with the acts_as_list and single table inheritence

Code details : http://pastie.org/1214846

But here I need create those entries with the scope on Relater only and not on RelaterFeed or RelatedLink I mean do not want to repeat these Position number 1,2,3 then 1,2,3 for same clip(i.e Relater). Currently it generating those positioning individually for RelatedFeed and for RelatedLink of same Relater(i.e clip)

Here I need something like when I'll assign Relater to RelatedLink or RelatedFeed it auto create positioning on the basis of Relater only like

RelatedLink : rec 1 -> position =1, relater_id=10, relater_type="Clip", type="RelatedFeed" rec 2 -> position =2, relater_id=10, relater_type="Clip", type="RelatedFeed" rec 3 -> position =3, relater_id=10, relater_type="Clip", type="RelatedFeed"

Then for RelatedFeed rec 1 -> position =4, relater_id=10, relater_type="Clip", type="RelatedFeed" rec 2 -> position =5, relater_id=10, relater_type="Clip", type="RelatedFeed" rec 3 -> position =6, relater_id=10, relater_type="Clip", type="RelatedFeed"

position will be like 1,2,3,5,6.. etc

Any Idea..?? How is to be done..?

Thank you :slight_smile:

In that till I've tried following way to assign scope for relater:

1 - acts_as_list :scope => :relater

2 - acts_as_list :scope => [:relater_id, :relater_type]

3 - acts_as_list :scope => 'relater_id=#{relater_id} and relater_type = \'#{relater_type}\''

But showing same result position 1,2,3 for RelatedFeed and 1,2,3 for RelatedLink.. not generating position number with the scope on Relater(i.e 1,2,3,4,5,6....etc)..

Guys, any Idea...???

I got the solutions and I would like to thank my PM(Mr.Rahul) for this solution..

Here what we have done..

Instead of assigning scope by using with acts_as_list ,

like: #model file class RelatedItem < ActiveRecord::Base acts_as_list belongs_to :relater, :polymorphic=>true

def scope_condition “relater_id = #{relater_id} and relater_type = ’#{relater_type}’” end

end

I hope it would be helpful for other Rails people also.!!!!!!! :slight_smile:
