Hi,

Has $inc been implemented yet?

[Maryna Brodina]

Hello!

Yes, it has been implemented.

To update objects in collection, send PUT request to according URL:
precurl -X PUT \
-H "Content-Type: application/json" \
-H "X-Appery-Database-Id: <database_id>" \
[-H "X-Appery-Session-Token: <session_token>" \]
-d '{“where”:<query>, “update”:<object>, “operations”:<operations>}' \
https:&#47;&#47;api&#46;appery&#46;io/rest/1/db/collections/<collection_name>/pre

where:
database_id is unique identifier of database.
session_token is session token which you use to do some actions with database.
collection_name is name of database's collection.
query is JSON query object that was built in accordance with the documentation of mongo quering. .
object is an JSON object with fields of object that should be updated.

operations is JSON update object with native mongo operations and fields of object that should be updated. Object was built in accordance with the documentation of mongo set operations. If operations object specified, update object fully ignored. Their functionality can not be used simultaneously.

You can use the following operations:

$set
$unset
$inc (Number type only)
$mul (Number type only)
$min (Number and Date type only)
$max (Number and Date type only)
