Overview

The View Index Manager interface contains the means for managing design documents used for views.

A design document belongs to either the “development” or “production” namespace. A development document has a name that starts with “dev_”. This is an implementation detail we’ve chosen to hide from consumers of this API. Document names presented to the user (returned from the “get” and “get all” methods, for example) always have the “dev_” prefix stripped.

Whenever the user passes a design document name to any method of this API, the user may refer to the document using the “dev_” prefix regardless of whether the user is referring to a development document or production document. The “dev_” prefix is always stripped from user input, and the actual document name passed to the server is determined by the “namespace” argument.

All methods (except publish) have a required “namespace” argument indicating whether the operation targets a development document or a production document. The type of this argument is [Symbol] with allowed values :production and :development.
