Mongoid deleting embedded documents does not persist

I have been running into an issue for hours and have Googled myself senseless.

I have a Mongoid model with an embedded document, like so:

embeds_many :tags, :as => :taggable

For some reason, attempting to delete this document appears to work in the console but then the documents come back after a reload. I have tried the following:

model.tags.delete_all

model.tags.each do |tag|
  tag.delete
end

model.tags.destroy_all

After all of the above, I can confirm that model.tags returns an empty array. Then to be safe, I even call model.save. If I reload the model, all of the embedded tags come back.

What is the correct way to delete embedded documents using Mongoid?

Well Its very simple but tricky ...

When you delete the tags , You need to reload the parent object.

Code 

model.tags.delete_all
model.reload

 model.tags.each do |tag|
  tag.delete
 end
 model.reload

model.tags.destroy_all
model.reload

This is the way your model will be reloaded and you will get right object
