Can someone please explain to me what locals[cdt][cdn] actually is doing? I know it’s necessary for child tables, but I don’t know why.

@cpurbaugh locals is the old cache that frappe use to store the data loaded. Basically is a namespace where you can access the information of a doctype, and some meta-information.

Ok, but what is cdt and cdn?
cdt = current doctype
cdn = current docname
cdt and cdn are passed as default arguments by frappe
