Smarter dirty checking with @Transient fields
---------------------------------------------
Key: HSEARCH-1093
URL:
https://hibernate.onjira.com/browse/HSEARCH-1093
Project: Hibernate Search
Issue Type: Improvement
Affects Versions: 4.1.0.Final
Reporter: Marc Schipperheyn
I found that if you have a field that is @Transient and depends on a Hibernate managed
field, this field is not updated when the underlying field changes.
{code}
@ManyToOne
@JoinColumn
@IndexedEmbedded
public Photo getPhoto() {
return photo;
}
@Transient
@Field
public String getMugshot(){
if(photo == null)
return null;
return getUserDirectory() + "/" + photo.getFilename();
}
{code}
This makes sense. However, it's not desirable. I would therefore want to propose an
annotation that can add some magic to dirty checking and inform Hibernate Search that when
@Field x gets dirty, the @Transient field should also be considered dirty
Something like
{code}
@ManyToOne
@JoinColumn
@IndexedEmbedded
public Photo getPhoto() {
return photo;
}
@Transient
@Field
@AssociateDirty(fields={"photo"})
public String getMugshot(){
if(photo == null)
return null;
return getUserDirectory() + "/" + photo.getFilename();
}
{code}
There are many names one might give to such an annotation. E.g. @YouDirtyMeDirty, but many
somehow sound a little "dirty" :-)
