Hi every one! I used Javers for history management. But i can't filter like instead of equals with commit properties information. How to do it?

example: John Smirt, i just want to filter "John " word to found "John Smirt"

Bartosz Walacik

@bartoszwalacik

hi, you mean SQL like with % ?

DienLH

@dienlh

yeap, @bartoszwalacik ! I seen source of Javers when generation query, i see that Javers used "=". If i want to use "Like", What should i do? please help me! Thanks

Bartosz Walacik

@bartoszwalacik

like is not supported

but you can contribute to Javers and implement support for likes :)

DienLH

@dienlh

@bartoszwalacik Ok thanks! I will apply if javers implement new version and support this.

Hey guys! I hope you are doing well! I want to use Javers in my pet project. And I use PostgreSQL as the main warehouse and MongoDB as a warehouse for audited data. Everything is working great, except for one thing. When I make several requests in a single transaction auditing data persists in Mongo with different commit version. Is it expected behavior when MongoDB is used? I just want to find changes that were been changed in one transaction. Сan someone point me in the right direction?

Bartosz Walacik

@bartoszwalacik

hi, javers doesnt know nothing about your transactions

helycopternicht

@helycopternicht

Thanks for the answer! And if I'll store audited data together with main data javers will use transaction right?

Bartosz Walacik

@bartoszwalacik

if in sql db - yes

helycopternicht

@helycopternicht

Hi, is there a way for TERMINAL snapshot to have the last know entity values rather being empty? Or, is there a easy way to retrieve the terminated object? I am using findSnapshots() in the context of Spring Boot. Thanks!

Btw, Javers is amazing work. Much more easier to configure and intuitive to use and query than envers.

Bartosz Walacik

@bartoszwalacik

Thanks @skogs, nice to hear that :)

but, no, there is no query for last snapshot of deleted object, if you'd like to contribute such feature, you are welcome

If I just want to use Javers to detect changes in a object graph, compared to the previous version, and then send notifications to clients if changed.
And I dont need the persistent respository of thye audit log.
Is Javers still a good match?

Bartosz Walacik

@bartoszwalacik

yes, thats javers core feature, diff

Daniel Engfeldt

@dniel

yeah, but when starting up without any special repository says "using in-memory repo, please register real repo" and the documentation says in-memory is only for testing, not for production.

But when running only for using diff-features and not persistence, is the default config with the in-memory enough and usable in production?

Bartosz Walacik

@bartoszwalacik

you dont get it, javers.compare() doesnt use any repo , its a pure function

Hi, it seems output from javers is colored red in intellij, which is default error color. Does anyone have a solution to this. Example of logging colored incorrectly (as I see it):
mar 01, 2020 10:04:56 FM org.javers.core.JaversBuilder bootAddOns
INFO: loading GroovyAddOns ...

Bartosz Walacik

@bartoszwalacik

it's INFO level, so how it can be red?

Björn Lindahl

@r3trobear_twitter

Good question. Can it be that it prints to stderr by default causing it to be treated as an error?

Bartosz Walacik

@bartoszwalacik

javers logs only to logger

Hi all, How to use Javers audit in a dropwizard project (No spring, spring-boot) ? Also is auto audit supported with dropwizard ? Persistence is done via dropwizard-hibernate. Thanks

Bartosz Walacik

@bartoszwalacik

Hi, where is the problem, if you don't use Spring, you have to create a Javers instance using JaversBuilder - see https://javers.org/features#javers-repository

Hi. I`m using Javers audit with MongoDB. Is there any way to archive (delete) Javers snapshots with Javers API? I need to remove obsolete snapshots in order to free up space in the DB

Bartosz Walacik

@bartoszwalacik

only deleteAll

MaximOsievskiy

@MaximOsievskiy

@bartoszwalacik Could you please explain in more details? Do you mean direct removal of documents from the jv_snapshots?

Bartosz Walacik

@bartoszwalacik

short answer is no, javers repository API is insert & read only
