Acts_as_list issue in single table inheritence

Rails
1

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 to 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 solution 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:
