        or

            form=SQLFORM(db.mytable,myrecord).process(onaccept=auth.archive)

        crud.archive will define a new table "mytable_archive" and store the
        previous record in the newly created table including a reference
        to the current record.

        If you want to access such table you need to define it yourself in a model::

            db.define_table('mytable_archive',
                Field('current_record',db.mytable),
                db.mytable)

        Notice such table includes all fields of db.mytable plus one: current_record.
        crud.archive does not timestamp the stored record unless your original table
        has a fields like::

            db.define_table(...,
                Field('saved_on','datetime',
                     default=request.now,update=request.now,writable=False),
                Field('saved_by',auth.user,
                     default=auth.user_id,update=auth.user_id,writable=False),

        there is nothing special about these fields since they are filled before
        the record is archived.

        If you want to change the archive table name and the name of the reference field
        you can do, for example::

            db.define_table('myhistory',
                Field('parent_record',db.mytable),
                db.mytable)

        and use it as::

            form=crud.update(db.mytable,myrecord,
                             onaccept=lambda form:crud.archive(form,

        If you have a table (db.mytable) that needs full revision history you can just do::

            form=crud.update(db.mytable,myrecord,onaccept=crud.archive)

        crud.archive will define a new table "mytable_archive" and store the
        previous record in the newly created table including a reference
        to the current record.

        If you want to access such table you need to define it yourself in a model::

            db.define_table('mytable_archive',
                Field('current_record',db.mytable),
                db.mytable)

        Notice such table includes all fields of db.mytable plus one: current_record.
        crud.archive does not timestamp the stored record unless your original table
        has a fields like::

            db.define_table(...,
                Field('saved_on','datetime',
                     default=request.now,update=request.now,writable=False),
                Field('saved_by',auth.user,
                     default=auth.user_id,update=auth.user_id,writable=False),

        there is nothing special about these fields since they are filled before
        the record is archived.

        If you want to change the archive table name and the name of the reference field
        you can do, for example::

            db.define_table('myhistory',
                Field('parent_record',db.mytable),
                db.mytable)

        and use it as::

            form=crud.update(db.mytable,myrecord,
                             onaccept=lambda form:crud.archive(form,

                             current_record='parent_record'))
