Updating 2 models at once with same attributes in ruby on rails?

Yes. See you are already using 'accepts_nested_attributes_for' in stock. Rb model which is a nice practice while saving multiple 'store_opening_stock' records from a stock model form.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
