Screencast: wrong argument type
23 Nov 2011

I am really surprised at how well-received my Conway's Game of Life screencast was. Seems that everyone who watched it liked it, which is always a nice thing :)

This week's screencast is a slightly more advanced topic: debugging a wrong argument type Module (expected class) error which was happening inside of the spree_paypal_express Spree extension.

It's 28 minutes of debugging goodness and you can view it here.


The next screencasts I will do are examples of how to do nested attributes within Rails, covering belongs_to, has_many and has_many :through associations, along with demystifying how nested attributes works within Rails.
