Hi,

rake db:mongoid:create_indexes does not create the defined indexes correctly in 3.0.0.rc.

In my model I use:

index(

{ project_id: 1, email: 1 }

, unique: true)
index(

{ project_id: 1, tag_ids: 1, active: 1, next_mailing: -1 }

)
index(

{ project_id: 1, created_at: -1 }

)

rake db:mongoid:create_indexes shows the following output in the console, which is wrong:

Creating indexes on: Subscriber for: {:project_id=>1, :email=>1}, {:created_at=>-1}, {:active=>1, :next_mailing=>-1}.

And in MongoDB the following indexes are created:

db.subscribers.getIndexes()
[
{
"v" : 1,
"key" :

{ "_id" : 1 }

,
"ns" : "test.subscribers",
"name" : "id"
},
{
"v" : 1,
"key" :

{ "project_id" : 1, "email" : 1 }

,
"unique" : true,
"ns" : "test.subscribers",
"name" : "project_id_1_email_1"
},
{
"v" : 1,
"key" :

{ "created_at" : -1 }

,
"ns" : "test.subscribers",
"name" : "created_at_-1"
},
{
"v" : 1,
"key" :

{ "active" : 1, "next_mailing" : -1 }

,
"ns" : "test.subscribers",
"name" : "active_1_next_mailing_-1"
}
]

Am I defining indexes in my models the wrong way?

Thanks and cheers
