Sean Busbey commented on AVRO-1886: ----------------------------------- thanks again for the work here [~MiroslavCsonka] and [~sldblog]! > Improve error reporting for schema validation > --------------------------------------------- > > Key: AVRO-1886 > URL: https://issues.apache.org/jira/browse/AVRO-1886 > Project: Avro > Issue Type: Improvement > Components: ruby > Reporter: Miroslav Csonka > Assignee: Miroslav Csonka > Fix For: 1.9.0, 1.8.2 > > > In Funding Circle we use avro schema to validate some financial data and > we've found ourselves wondering what is invalid. We've noticed that avro > [does already > validation|https://github.com/apache/avro/blob/master/lang/ruby/lib/avro/schema.rb#L94], > but does not report what fields are invalid, so we've decided to change it > and we use Avro as a validation library. > h5. What error messages to expect? > We communicate errors for a given payload in format "at <path> <expected> > <received>". > For <path> we've decided to use syntax similar to json path: > * . refers to root > * \[0\] first index in array > * .age would match 42 from {"age": 42} > Error within object *person* and his optional array *houses* on *second item* > with key *number_of_rooms*: > {quote} > at .person.houses\[1\].number_of_rooms expected type long, got string > with value "not valid at all" > {quote} > Example of multiple errors for a single payload: > {quote} > at .\[0\] expected type int, got null > at .\[1\] expected type int, got string with value \"e\" > {quote} > More examples can be seen at > https://github.com/apache/avro/pull/111/files#diff-830ac80276854fceefa3f92c346d165f -- This message was sent by Atlassian JIRA (v6.3.4#6332)
