#with(options) ⇒ Document

Note:

This method will instantiate a new client under the covers and can be expensive. It is also recommended that the user manually closes the extra client after using it, otherwise an excessive amount of connections to the server will be eventually opened.

Tell the next persistance operation to store in a specific collection, database or client.

Examples:

Save the current document to a different collection.

model.with(collection: "secondary").save

Save the current document to a different database.

model.with(database: "secondary").save

Save the current document to a different client.

model.with(client: "replica_set").save

Save with a combination of options.

model.with(client: "sharded", database: "secondary").save

Parameters:

  • options (Hash) —

    The storage options.

Options Hash (options):

  • :collection (String, Symbol) —

    The collection name.

  • :database (String, Symbol) —

    The database name.

  • :client (String, Symbol) —

    The client name.

Returns:

Since:

  • 3.0.0
