accepts_nested_attributes_for rails 4 is not deleting

Question

I have been reading and researching for about 3 days now. This is my last resort.

land.rb:

has_many :uploads , :dependent => :destroy
accepts_nest         


        

Answer 1

You need to allow the :_destroy parameter for your nested model as well, as this gets used when you check the 'Delete' checkbox in the form. It's Rails' way of flagging model instances that have to be destroyed.

def land_params  
  params.require(:land).permit(uploads_attributes: [:id, :filename, :_destroy])
end

Answer 2

The OP didn't have the same problem as me, but for anyone coming across this question, for me, it was the absence of allow_destroy: true as an argument on the accepts_nested_attributes call in the model.
