by compare key
This block is part of the array group and was last modified in core v13.0.8.
by compare key v13.0.8 Merge array increment by deep key
- base array required
arrayarray to merge into
- from array required
arrayarray to merge from
- deep key
valuethe key to be merged, if none given, the main array wil be merged
- compare key required
valuethe keys to be compared, based on the comparision, these objects are merged
- increment keys
arrayKeys to increment, within the array being merged. For example
quantity
- merged array
array
Merges base_array then merge_from into one array deduplicated on the string value of compare_key: the first occurrence is kept and later occurrences shallow-merge over it, their fields overwriting, EXCEPT the increment_keys fields which are summed numerically. With deep_key set, items are drawn from the array at that path inside each element. Non-array base outputs [] plus error BASE_ARRAY_IS_INVALID; empty compare_key outputs [] plus MISSING_COMPARE_KEY.

A typical wiring for by compare key: with values feeds the base_array pin; with values feeds the merge_from pin; value feeds the compare_key pin; the merged_array out pin feeds length.
