The book is incorrect. If you want to rely on the generic.json view to
generate the JSON response, then you must return a dictionary (otherwise,
no view will be called, and whatever you return will be returned directly).
In this case, the .validate_and_insert method returns a DAL Row object (not
a database record, just a Row object that contains "error" and "id" keys).
Apparently, when you return a Row object, the response body ends up being
just a concatenation of its keys, so in this case, we get "errorid" as the
response.
You have a few options:
1. Put the result in a dictionary:
return dict(result=db[table_name].validate_and_insert(**vars))
2. Convert the Row object itself to a dictionary:
return db[table_name].validate_and_insert(**vars).as_dict()
3. Return JSON directly:
from gluon.serializers import json
return json(db[table_name].validate_and_insert(**vars))
