[jira] Closed: (CAY-1261) Auto-inject values in NEW objects with
declared qualifiers
[ https://issues.apache.org/jira/browse/CAY-1261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrey Razumovsky closed CAY-1261.
----------------------------------
Resolution: Fixed
Finished; any advanced inject abilities will go through separate JIRAs. The most common case, ASTObjPath=ASTScalar [ AND ASTObjPath=ASTScalar]* is covered

True... The implementation of the client callbacks would require
considering various scenarios. At the minimum we will need a way to
specify callbacks/listeners separately on the client and the server
(e.g. it probably wouldn't make sense to init the same default values
in pre-persist first on the client, and later on the server; or if the
server does some audit recordings on commit, the same processing is
meaningless on the client). Another elephant in the room is callbacks
in locally nested contexts... So some food for thought.

I think we sould first then do something with lifecycles on ROP client..
There are none yet, and e.g. injection works on client

BTW, wonder if we could introduce our own internal lifecycle listeners
for processing of objects similar to this case (a pre-persist listener
on CayenneDataObject). Seems like a rather flexible approach. Just an
idea anyways...

Yeah, big +1 from me as well. It was one of the top items on my list
of things I want to see in Cayenne. Kudos to Andrey for making it a
reality.

But yes, injections will be enabled if you use qualifiers like
isDeleted=false, then the value will be injected when creating an object

Hi Ari,
I can't think of the situation when the feature should be disabled. I think
it just spares time and lines of code when working with entities with
qualifiers. Initial values will be injected only if that is trivial (in
fact, only equality expressions - otherwise Cayenne just cannot decide what
to inject).
For "isDeleted" case I intentionally implemented CAY-1235 and CAY-1236 and
use them in pair, more at [1]. I agree this should be mentioned in docs,
though.
And once again, currently the feature is quite trivial, e.g. it does not
support db paths, chained paths and so on.. If needed, we can discuss an
improvement

Hi Andrey
This is a very interesting feature, and I think that before you close the task we need some documentation on the web site for it. Is there a way to enable or disable this feature? Is it designed to work in the vertical inheritance situation as well as the common isDeleted use-case?
