Query for Author

[BenPezzei]

Hi,

We would really appreciate a possibility to use QueryBuilder (or JqlQuery for that matter) to search for changed objects who were updated/deleted/etc by a certain User (=Author)

After looking @ the code a bit, I guess this new Paramter has to be passed all the way "down" to JaversRepository (unfortunately).

Any ideas/hints if this feature may be available in javers?

tnx & regards

It would be easy to implement but only for Snapshot queries.
JaversRepository stores only snapshots. When you are querying for Changes, first, Snapshot query is executed and then Changes are recalculated as differences between Snapshots pairs.

For example:

javers.commit("author1",object);
javers.commit("author2",object);
javers.commit("author2",object);

If you query for Changes done by "author2", two snapshots will be found, and only third change set will be returned (between second and third commit).

Hi,

A list of snapshots would be sufficient for starters. Furthermore the API should be flexible enough to cope with "authorOnly"-Queries. Right now, I don't see a way to query for any changes/snapshots disregarding the entityClass.

Again, any hints if this may be implemented in the near future?

Regarding a pull-request: I may do it myself by modifying the QueryBuilder-class (adding static author-method) and pipe the arguments all through down the way to the repository (similar to commitId-Handling)

tnx & regards

Hi @BePe2, we are now in the middle of huge SqlRepository refactoring, so I cant promise you anything,
think about PR. This feature is easy to implement, look at this (merged) PR https://github.com/javers/javers/pull/318/files when commitId filter was added. Author filter can be done in a similar way.
