I am using Mongoid as my ODM. I am also using single collection inheritance. Tire wants to put all of my sub classes into the same elastic search type.

I have a class type of Foo,
When I have a sub class of Bar, tire wants to put all 'bars' in elastic search as 'foos'.

I noticed a method named .document_type, which will allow me to change what elastic search '_type' I want. In my 'Bar' model I do this:

document_type 'bar'

If I call '#update_index' on my bar model, it will set the actual _type field on my mongoid instance to 'bar'. It should be 'Foo::Bar'. If I save my model afterwards to the database, it will save the _type field as 'bar'. Is this the intended behavior of '.document_type' ?

Hi, it's a known bug, there are several issues opened for that: #265, #201 related to that. It needs to be solved, definitely. And it needs to be solved with the multimodel search bug, #218 looks very promising in this regard.

I don't know that those issues directly solve the one I am experiencing. However they do address the root issue why I started playing around with the document_type settings. I don't think update_index should be able to over write any model attributes. At least not any that could potentially be persisted to the database after a manual index update.

Thank you for your huge contribution to the community with Tire. I understand I am complaining without offering solutions. So I will take a stab at a solution when I have some time.

#218 does look like a good solution to the multi model issue. Is there something holding you back from pulling that fix into master?

Time :) (Joking.) Seriously, I need to review all the patches related to this issue, and somehow kill it in one swoop. I got burned with some commits such as 1d6b267 and am a bit reluctant to "just pull" on a piece-by-piece basis now, usually pulling the patch means making sure it still makes sense in the grand picture....
