Question

Normally you would use something like attr_accessible :name, :email to allow for mass assignment for those specific fields but how do you do this in mongoid for an embedded document like :nick_names? I tried tagging it at the end of attr_accesible but it does not work.

Thanks!

Answer 1

I would use a combination of criteria and update all. For instance:

Foo.where(country: nil).update_all(country: "USA")

If you’re trying to do it via a Rails update, then @apneadiving is correct in that you need to enable accept_nested_attributes_for in the parent model.
