Delete one version

[vighnesh1987]

I've a Rails model set up with Mongoid::Versioning.

class Post
  include Mongoid::Document
  include Mongoid::Timestamps

  include Mongoid::Versioning

  field :name, type: String
end

I want to delete a specific older version. For eg.

post = Post.create name: 'A'
post.update_attributes name: 'B'
post.update_attributes name: 'C'
post.version #=> 3
post.versions.count #=> 2
first_version = post.versions.first #=> #<Post _id: , created_at: _, updated_at: _, version: 2, name: "B">

I want to delete first_version, but when I try to delete it..

first_version.delete
post.versions.count #=> 1
post.reload
post.versions.count #=> 0

..all versions get deleted.

I've tried using destroy instead, tried running the code inside a block passed to post.versionless, to no avail. This definitely looks like a bug. Am I doing something wrong?

I've gotten it to work with Mongoid::Paranoia. But it'd be nice to have the flexibility of not using Mongoid::Paranoia.

I'll take a look.

deleted = post.versions.first
post.versions.delete(deleted)

Please re-open if this doesn't work for you.
