Extend modified flags to support track changes within components

[robertovaldesperez]

One question, I have mapped the fields this way:

Component(x => x.RentSearchParameters, m => { m.Map(x => x.MinPrice).Column("precio_min_alquiler").Nullable(); m.Map(x => x.MaxPrice).Column("precio_max_alquiler").Nullable(); m.Map(x => x.ApproxPosition).Column("posicion_aproximada_alquiler").Nullable(); m.Map(x => x.Timing).Column("timing_alquiler").Nullable(); m.Map(x => x.Step).Column("step_alquiler").Nullable(); });

Is it possible to audit them separately?

precio_min_alquiler - MinPrice_mod
precio_max_alquiler - MaxPrice_mod
posicion_aproximada_alquiler - ApproxPosition_mod
...

instead of

precio_min_alquiler
precio_max_alquiler
posicion_aproximada_alquiler
RentSearchParameters_mod
...

Sorry, dont understand. What do you mean with "seperately"?

Also, is this a bug? Or is it a question how to use/configure Envers? If it is the latter, please post it here instead, http://groups.google.com/group/nhusers.

@RogerKratz Is a question about use/configure I will ask in the community. thank you

@RogerKratz I have asked in the community for 10 days but I have not received an answer. Could you help me with the previous question?

Component(x => x.RentSearchParameters, m => { m.Map(x => x.MinPrice).Column("precio_min_alquiler").Nullable(); m.Map(x => x.MaxPrice).Column("precio_max_alquiler").Nullable(); m.Map(x => x.ApproxPosition).Column("posicion_aproximada_alquiler").Nullable(); m.Map(x => x.Timing).Column("timing_alquiler").Nullable(); m.Map(x => x.Step).Column("step_alquiler").Nullable(); });

and I get this result:

...
precio_min_alquiler
precio_max_alquiler
posicion_aproximada_alquiler
RentSearchParameters_mod

Is it possible to configure nhibernate.envers so that each field has its corresponding field that indicates that it has been modified?

precio_min_alquiler - MinPrice_mod
precio_max_alquiler - MaxPrice_mod
posicion_aproximada_alquiler - ApproxPosition_mod
...

[RogerKratz]

Sorry, dont understand. what do you mean with "and I get this result"? Result of what?
And what is "posicion_aproximada_alquiler"?

Do you want to have custom names of your property modification flags? Or do you want more/fewer flags?

How does your envers configuration look like?

Hi @RogerKratz

I need to have a mod flag for each field, but with FluentNHibernate.Mapping.ComponentPart I only get one mod flag for all fields.

For example, this is my ClassMap

and envers generate one mod flag for all fields

and i need to generate a mod flag for each field with the FluentNHibernate.Mapping.ComponentPart, it's possible?

[RogerKratz]

Ah, I see. Didn't even remember that it worked that way (I don't use modified flags myself).

Modified flags is a direct port from Hibernate's envers version. Found this issue there, HHH-10859, so if I understand you correctly, I'm afraid what you want to do isn't possible ATM. I personally don't have the time trying to fix this, at least not until it's impl in Hibernate so it's easy to port.
You are of course welcome to create a pull request and provide a fix yourself.

reopening the issue now when when it's clear what it's about

Hi @RogerKratz thank you so much for help me. I will wait for it to be fixed.
