Your problem is that you have a record #weblink{} but the table you create
is named ?TABLE which is the value 'links'. You have not supplied
{record_name, weblink} so the default record name becomes the same as the
table name. The error mnesia reports is because there is no table in which
to place #weblink{} records, but you should have one named links. Test with
`mnesia:table_info(links, all)`.
