repair\_tickets and rp\_parts are HABTM.

If I do:

> > repair\_ticket1.rp\_parts  
> > =\> [#\<RpPart id: 1, …"\>, #\<RpPart id: 1,…"\>, #\<RpPart …"\>]

I only want to delete one of those RpPart id:1, and not both of them. Is  
it possible? How can I do that?

If you want to remove duplicates from your array you do

repair\_ticket1.rp\_parts.uniq!
