Understanding insertreference in corvid

Hi,
So the function has the following parameters:

  • collectionName - name of the collection that contains the referring item (e.g. if the collection B has a reference field to the collection A, then the collection A will be the name to insert).

  • propertyName - the property to insert the reference into (column id in database A).

  • referringItem - The referring item or referring item’s ID.

  • referencedItem - The referenced item, referenced item’s ID, an array of referenced items, or an array of referenced item IDs.
    You can see complete description with an example here .
