Hi,

I am currently trying to implement a problematic mapping for a given entity but have an issue. In the entity the ID is a UUID.. I can not find a way to register a bridge to handle the type. I have created and tested a bridge.

mapping.entity(Article.class).indexed().indexName("article")
.property("uid", ElementType.METHOD).documentId().field().bridge(HibernateSearchUUIDBridge.class)

Is there a way to do this? is it possible to register with hibernate a default bridge for a type?

Just a note to this. I can not use annotations and have to use java.util.UUID. a default bridge for UUID would be nice... the code would be simple..

@Override
public void set(String name, Object value, Document document,
LuceneOptions luceneOptions) {

UUID uid = (UUID)value;
Field field = new Field(name, uid.toString(), luceneOptions.getStore(), luceneOptions.getIndex(), luceneOptions.getTermVector());

document.add(field);
}


@Override
public String objectToString(Object object) {

UUID uid = (UUID)object;
return uid.toString();
}

@Override
public Object get(String name, Document document) {
String result = document.get(name);
UUID uid = UUID.fromString(result);
return (Object)uid;
}

Thanks,
Greg B.

Hi,


I'm not sure if I understood the question; are you saying that this code is not working?
Or just that you would like to register the HibernateSearchUUIDBridge for all UUID instances, to be applied automatically? That is currently not possible.


Absolutely, that would be nice to add. I think it's not there as nobody asked for it and we didn't think about it :)
Would you like to create a patch? We'll include it in the next release.

This is a starting point: http://community.jboss.org/wiki/Contrib ... nateSearch
but of course if you need help you can ask here, on the mailing list or on IRC as documented http://hibernate.org/community

thanks for the quick reply.

I will have a go at creating the patch.

The code does not work, I can not seem to find a way to add a field bridge to a document Id.

cheers,
Greg B.

ok I have made the changes and added test cases in-line with what was already done.

I have a small issue tho, I can not get all test cases to pass when using Maven. They seem to run fine in eclipse.

It seems that when test cases are storing an index on the file system they fail.. I am developing on windows.. most of them are passing.


an example

Hi,
you're right there is an issue with paths under Windows. Sorry we didn't spot that as nobody on the team is using Windows but we'll get that fixed as soon as possible.

have tested the change, do I tag my changes or something so they can be picked up?

Hi,
first step is you should create a issue on JIRA so that we track this as a new feature: https://hibernate.onjira.com/browse/HSEARCH

To send the code changes you can either attach a traditional patch file to the issue in JIRA, or if you're familiar with git and github you can send a pull request.
Sending a pull request is preferable ;)

Last step (first time only) is to sign the contributor agreement:
please create an account on jboss.org if you don't have one and sign https://cla.jboss.org/ for the project "Hibernate". sorry for the bureaucracy, but it's just a short agreement and a checkbox it won't take you long.

then if you like you could subscribe to the developers mailing list http://hibernate.org/community/mailinglists and introduce yourself.

thank you!

Hi, I have a similar problem. Have you found a solution to create a document id bridge for the programmatic mapping? Thanks

Hi, what is your problem? Could you post an example or create a testcase? I don't think it's the same issue, as the UUID patch was integrated.

Hi, in my case I am trying to implement a problematic mapping for a entity. The entity has an an composite primary key annotated with @EmbeddedId.



I try the same code, but the code does not work:



Exception occurred during event dispatching:
org.hibernate.HibernateException: could not init listeners
...
Caused by: org.hibernate.search.SearchException: Unable to guess FieldBridge for id
...


I need an advise to solve my problem. Thanks
