removing rows doesnt work

[paweł kamiński]

I have simple functionality where I fetch N items from collection and after I process them I can remove those items from db.

I set JacksonDBCollection to use String as key type and I am extending Storable for all storable domain objects

public abstract class Storable
{
    @Id
    private String id;

    public String getId()
    {
        return id;
    }

    public void setId(String id)
    {
        this.id = id;
    }
}

in my dao I tried to implement removing like this

public void removeStatuses(List<String> ids)
{
   // JacksonDBCollection<T, String>
   getCollection().remove(DBQuery.in("_id", ids), WriteConcern.JOURNALED);
}

but this didnt work. I tried to replace _id with id (as in Storable class)

public void removeStatuses(List<String> ids)
{
   // JacksonDBCollection<T, String>
   getCollection().remove(DBQuery.in("id", ids), WriteConcern.JOURNALED);
}

finally I implemented removing like this (which is native mongo api)

public void removeStatuses(List<String> ids)
{
    final BasicDBList value = new BasicDBList();
    for (String id : ids)
    {
        value.add(new ObjectId(id));
    }
    final BasicDBObject q = new BasicDBObject("_id", new BasicDBObject("$in", value));
    getCollection().getDbCollection().remove(q, WriteConcern.JOURNALED);
}

what I am doing wrong :/ I am using mongo-jack 2.0.0

thanks

There are several open issues that are some variation of this same problem,
which is that there are issues serializing _id particularly with
polymorphic objects.

Concise repro here:

This shouldn't be too hard to fix, but I am hesitant to sink time into it
as at present there are no project admins who are able to look at and merge
pull requests.

Which is really a bummer because Mongojack is a such a useful tool. There's been active contribution to the project but releases are so few and far between that it becomes demotivating for people willing to submit PRs

Indeed. That is a killer.

The project should really just be moved and maintained by someone else under a different name.
