Module: RESTFramework::BulkCreateModelMixin

Included in:
BulkModelControllerMixin
Defined in:

Overview

Mixin for creating records in bulk. This is unique compared to update/destroy because we overload the existing ‘create` action to support bulk creation.

def create
  if params[:_json].is_a?(Array)
    records = self.create_all!
    serialized_records = self.bulk_serialize(records)
    return api_response(serialized_records)
  end

  return super
end

#create_all! ⇒ Object

Perform the ‘create` call, and return the collection of (possibly) created records.

def create_all!
  create_data = self.get_create_params(bulk_mode: true)[:_json]

  # Perform bulk create in a transaction.
  return ActiveRecord::Base.transaction do
    next self.get_create_from.create(create_data)
  end
end

#get_options_metadata ⇒ Object

While bulk update/destroy are obvious because they create new router endpoints, bulk create overloads the existing collection ‘POST` endpoint, so we add a special key to the options metadata to indicate bulk create is supported.
