1.5.1. /db/_design/design-doc
HEAD
/{db}/_design/{ddoc}
Returns the HTTP Headers containing a minimal amount of information about the specified design document.
See also
GET
/{db}/_design/{ddoc}
Returns the contents of the design document specified with the name of the design document and from the specified database from the URL. Unless you request a specific revision, the latest revision of the document will always be returned.

PUT
/{db}/_design/{ddoc}
The PUT method creates a new named design document, or creates a new revision of the existing design document.
The design documents have some agreement upon their fields and structure. Currently it is the following:
language (string): Defines Query Server to process design document functions
options (object): View’s default options
filters (object): Filter functions definition
lists (object): List functions definition. Deprecated.
rewrites (array or string): Rewrite rules definition. Deprecated.
shows (object): Show functions definition. Deprecated.
updates (object): Update functions definition
validate_doc_update (string): Validate document update function source
views (object): View functions definition.
autoupdate (boolean): Indicates whether to automatically build indexes defined in this design document. Default is
true
.
Note, that for filters
, lists
, shows
and updates
fields objects are mapping of function name to string function source code. For views
mapping is the same except that values are objects with map
and reduce
(optional) keys which also contains functions source code.

DELETE
/{db}/_design/{ddoc}
Deletes the specified document from the database. You must supply the current (latest) revision, either by using the rev
parameter to specify the revision.
See also
COPY
/{db}/_design/{ddoc}
The COPY (which is non-standard HTTP) copies an existing design document to a new or existing one.
Given that view indexes on disk are named after their MD5 hash of the view definition, and that a COPY operation won’t actually change that definition, the copied views won’t have to be reconstructed. Both views will be served from the same index on disk.

HEAD
/{db}/_design/{ddoc}/{attname}
Returns the HTTP headers containing a minimal amount of information about the specified attachment.
See also
GET
/{db}/_design/{ddoc}/{attname}
Returns the file attachment associated with the design document. The raw data of the associated attachment is returned (just as if you were accessing a static file.

PUT
/{db}/_design/{ddoc}/{attname}
Uploads the supplied content as an attachment to the specified design document. The attachment name provided must be a URL encoded string.
