[erlang-questions] clarify: mnesia foreign_key

[Paul Mineiro]

hi.

the documentation indicates that when foreign_key is used, "Instead of
using the record key to determine which fragment to access, the value of
the Attr field is used."

how does this work with operations that take a key only and not a whole
record?
