Batch insert/update using Mongoid?
I googled and all others, but I didn't find the a开发者_StackOverflow社区nswer. The question is:
Hi, how can I do batch insert with Mongoid to MongoDB?
You can insert a batch array of hashes using the ruby mongo driver's insert method. From any Mongoid class, you can call collection to access it.
batch = [{:name => "mongodb"}, {:name => "mongoid"}]
Article.collection.insert(batch)
If you want to batch insert Mongoid documents (models) instead of hashes, call your model's as_document method before placing it into array:
@page_views << page_view.as_document
...
PageView.collection.insert(@page_views)
You can use this:
books = [{:name => "Harry Potter"}, {:name => "Night"}]
Book.collection.insert_many(books)
And I find that "insert" does not work for me(Monogoid 5.1.3):
NoMethodError: undefined method `insert' for # <Mongo::Collection:0x007fbdbc9b1cd0>
Did you mean? insert_one
insert_many
inspect
This is the source code from "lib/mongo/collection.rb":
# Insert the provided documents into the collection.
#
# @example Insert documents into the collection.
# collection.insert_many([{ name: 'test' }])
#
# @param [ Array<Hash> ] documents The documents to insert.
# @param [ Hash ] options The insert options.
#
# @return [ Result ] The database response wrapper.
#
# @since 2.0.0
def insert_many(documents, options = {})
inserts = documents.map{ |doc| { :insert_one => doc }}
bulk_write(inserts, options)
end
Mongoid's Model.create
method can accept an array to create documents.
From the Mongoid docs:
Person.create([
{ first_name: "Heinrich", last_name: "Heine" },
{ first_name: "Willy", last_name: "Brandt" }
])
