-*   Add migration history to schema.rb dump.
-    Loading schema.rb with full migration history
-    restores the exact list of migrations that created
-    that schema (including names and fingerprints). This
-    avoids possible mistakes caused by assuming all
-    migrations with a lower version have been run when
-    loading schema.rb. Old schema.rb files without migration
-    history but with the :version setting still work as before.

     that the association is expecting.
