Create and drop indexes for a single collection in Mongoid 3.0

[Andreas Saebjoernsen]

Some gems we depend upon drop and create indexes during testing. In Mongoid 2.4 this can be done with:

  - Dropping indexes if there are any:  Book.collection.drop_indexes

  - Creating indexes if there are any:  Book.collection.create_indexes

I can perform the same functionality by accessing the index through the session, but is there a more concise way of creating and dropping indexes in Mongoid 3.0?

Best,

Andy

For both calls:

Book.remove_indexes
Book.create_indexes

If you want to drop all indexes on a collection, even ones that aren't defined in Mongoid:

Book.collection.indexes.drop

Thank you. The gem in question, mongoid-slug, also use a composite key made from two fields. I can not find any documentation on how to create composite keys in Mongoid 3.0. Please let me know if this is still supported. 

This is a simple example on how composite keys are used in mongoid-slug:

class Animal

  include Mongoid::Document

  field :name

  field :nickname

  key :name, :nickname

end

Which I could change to the new syntax:

  field :_id, type: String, default: ->{ default_field }

I was not aware of the 'key :field_1, :field_2' syntax before looking at this gem and

can not see anything about it in the documentation. Does the

'key :field_1, :field_2' syntax have an equivalent and supported analogue in 

Mongoid 3.0? 

 

Best,

Andy
