[Rails] Deleting only first occurrence from many to many collection

[Sadaf Noor]

Hello,
I am having a little bit problem in deleting duplicate entry of my many to
many tables.

In many to many fields delete method is deleting all the occurrence of
collection. Say I have (demo example):

class user < ActiveRecord::Base
  has_and_belongs_to_many :cars
end

class car < ActiveRecord::Base
  has_and_belongs_to_many :users
end

users and cars are many to many relationship, I have defined my
users_cars table.
Now user can have repetitive car entry as relation. For example:

Car: A,B,C User: U1,U2,U3

U1=[A,B,C,A,A,A,B]

Which can be implemented using many to many relationship, the way I have
implemented. BUT, at the time when I want to delete one of the car entries
of user the problem occurs.

Users.cars.delete(car) #deletes all occurrence of car
Users.cars.delete_at(User.cars.find_index(video_card)) #delete_at does not exist

Now how to resolve this?

I have also posted at stackoverslow (
http://stackoverflow.com/questions/31507056/deleting-first-occurrence-from-many-to-many-collection-entry-at-rails).
Please feel free to answer, and/or upvote.


Thanks.

Thanks for the help, everyone.  After following the link to github that 
Elizabeth posted I was able to cut and paste some updated code.

Thanks again.
