Question

I have a nested resources:

resources :bills do
  resources :debts
end

and when I make a delete link in the index html in the debts view like this:

<td>
   <%= link_to "Delete", [@bill, @debt], confirm: "Are you sure?", method: :delete %>
</td>

the bill is deleted, not the debt.
What happens?, How can I deleted only one debt of a specific Bill?
This is my delete action in my debt’s controller.

def destroy
    @bill = Bill.find(params[:bill_id])
    @debt = @bill.debts.find(params[:id])
    @debt.destroy

    flash[:notice] = "The debt was successfully deleted"
    redirect_to bill_debts_url    
end

And my models:

Bill model:

class Bill < ActiveRecord::Base
  has_many :debts
end

Debt model:

class Debt < ActiveRecord::Base
  belongs_to :bill
end

Thanks in advance!

Answer 1

You have a has_many association. If a bill has_many debts, then bill.debts is an association, not a single object. You need to call destroy_all on that object to destroy all of them:

def destroy
  @bill = Bill.find(params[:bill_id])
  @debts = @bill.debts.find(params[:id])
  @debts.destroy_all

  flash[:notice] = "The debt was successfully deleted"
  redirect_to bill_debts_url    
end

That being said, I’m not sure why the Bill is being destroyed at all…
