The provided copyEntry
function appears to interact with what is likely a database operation to copy an "entry" associated with a specified nodeId
to a new location, while also mapping specific attributes or fields from the source to their corresponding destinations.
Here's a breakdown of what the code does step-by-step:
-
Function Definition: The function takes a single parameter,
nodeId
, which identifies the "node" or entry to be copied. -
Purpose: The primary purpose of this function is to invoke a method,
db.entryCopier
, to perform the copying of some data associated with the givennodeId
. -
JSON Object Construction: Inside the function, a JSON object is constructed and passed to the
db.entryCopier
method. This object defines the details of the copy operation:"THIS_PATH":"/workflow-demo/3"
: Specifies the current path of the entry to be copied."THIS_NODEID":nodeId
: Uses thenodeId
parameter to identify the specific entry to copy."NEW_PATH":"/workflow-demo/4"
: Indicates the new path where the copied entry will be stored."COPY"
: A nested object that maps fields or attributes in the source to fields/attributes in the destination:1000030:1000014
: Copies the field with ID1000030
to a new field with ID1000014
.1000031:1000015
: Copies the field with ID1000031
to a new field with ID1000015
.1000032:1000018
: Copies the field with ID1000032
to a new field with ID1000018
.1000033:1000020
: Copies the field with ID1000033
to a new field with ID1000020
.
-
Stringify and Pass to Method: The JSON object is converted to a string using
JSON.stringify
. This is commonly done when serializing data for APIs or functions that might require input in a string format. -
Method Invocation: The stringified JSON object is passed to the
db.entryCopier
method, along with aresponse
parameter.db.entryCopier
is likely a method interacting with a back-end system or database to execute the copy operation.- The
response
parameter isn't defined within the provided code and might be a callback or a handler for the operation's results.
Summary of Functionality:
The copyEntry
function facilitates the copying of data from one location (path) to another within some workflow or entry management system:
- It copies the entry identified by
nodeId
in the source path ("/workflow-demo/3"
) to the destination path ("/workflow-demo/4"
). - While copying, it maps specific fields or attributes from the source entry to new IDs in the destination entry according to the
"COPY"
mappings.
