I exploit distinctive area mapping, however as a substitute of blocking the import on duplicates from CSV, it overwrites the information in Drupal and inserts the brand new worth from the CSV file.
That is the default habits with distinctive title area mapping:
“IF the title is duplicate THEN overwrite previous merchandise in Drupal with new merchandise from spreadsheet”
However I am in search of this behaviour:
“IF the title is duplicate THEN skip new merchandise from spreadsheet, and preserve previous authentic merchandise in Drupal intact”
I’ve area tamper, the merchandise area AND the importer area all set to distinctive. All of it works high quality, however on duplicate feed imports, as a substitute of stopping import of duplicate gadgets, it overwrites the previous area, and inserts the brand new duplicate…
My purpose is for Drupal to PREVENT the duplicate area to be populated in any respect…the identical method should you manually attempt to enter a reproduction entry in manually imputing content material, it exhibits an error and prevents you from submitting the shape.
Is that this even doable with out customized code? Possibly with guidelines?
