 Finally, you may wish to recreate objects from a table that already exist, for

-is fetchable (most likely to check if it exists.)
+this purpose we have the module `fetch` module, from this you can import `

+We also have four helper methods, `fetch_range(class_, range_)` and
 `fetch_all(class_)` are very similar: the former fetches the records
 fetchable from the object id range provided by the user, whereas the
 latter fetches all records. Both return a tuple of `class_` objects.
