named_scope

[et...@maven-soft.com]

Is named_scope available with MongoMapper? If so, what do you need to
do in order to use them? Simply calling named_scope doesn't seem to
work like it did in ActiveRecord.

Here is the class and resulting error:

class CommitFile
include MongoMapper::EmbeddedDocument

key :commit_id, ObjectId
key :filename, String
key :diff, String
key :state, String

belongs_to :commit
has_many :comments

named_scope :added, :conditions => {:state => 'added'}, :order =>
'filename'
named_scope :removed, :conditions => {:state => 'removed'}, :order
=> 'filename'
named_scope :modified, :conditions => {:state => 'modified'}, :order
=> 'filename'
end

undefined method `named_scope' for CommitFile:Class (NoMethodError)

Named scopes do not work in mongomapper. I think it would be a cool
feature. I just wrote an adapter for the AASM gem and the activerecord
version inculdes a bunch of support for named scopes. Would be nice to
be able to port these over as well.

Someone has been working on it. I also have ideas. Not in there right now.

One thing nice thing about mongo is that queries are basically chainable. To add a scope, just add to the query selector document. So named_scope should be quite a bit less complicated here than with the sql.

You can find named_scope in this branch:

I don't think that branch has any tests and is a direct port of AR which doesn't make sense to me. Unless it has changed since I looked at it or I'm thinking of something else.

I have plans for named scope type stuff in MM but it will be a few releases.

Yes, that's right, I just directly ported across named_scope from
activerecord, and hacked it in without tests in a hurry so I could
proceed with a current project. I wouldn't recommend anyone actually
using that branch, there are definitely a few problems with it.
