Question

We are currently migrating from MySQL to MongoDB, and I stumbled over the following:

MyModel.destroy(params[model_ids]) # Remove many objects at once by passing an array of IDs

This worked for ActiveRecord, but for MongoDB it doesn’t: I have to iterate over the IDs, find it, and then call the delete method on the instantiated object:

MyModel.find(params[model_ids]).each do |item|
  item.destroy
end

Is this the correct way to go? And is there a special reason why Mongoid doesn’t offer the mentioned functionality?

Thank you!

Answer 1

You can try this

MyModel.where(:_id.in => params[model_ids]).destroy

In Mongoid you can run the destroy method on a criteria.
