Allow multiple columns with same column name

[floriansattler]

It would be important to handle columns with same name in the csv-mapper.

Use case is to provide additional image links for a datafeed for google merchant center. Google always expects the same header additional_image_link.

The following code for example creates two additional_image_link columns but all of the containing URLs end with "-3" instead of "-1" and "-3"

  -
    type: "addColumn"
    toCol: "additional_image_link"
    valueTransformers:
      -
        type: "multipartString"
        parts:
          -
            valueTransformers:
              -
                type: "constant"
                value: "https://coeur.scene7.com/is/image/Coeur/"
          -
            valueTransformers:
              -
                type: "column"
                col: "ID"
          -
            valueTransformers:
              -
                type: "constant"
                value: "-1"
# setze zusätzliche Bild-Url aus Media-Url und SKU und -3 zusammen  
  -
    type: "addColumn"
    toCol: "additional_image_link"
    valueTransformers:
      -
        type: "multipartString"
        parts:
          -
            valueTransformers:
              -
                type: "column"
                col: "Media-Url"
          -
            valueTransformers:
              -
                type: "column"
                col: "ID"
          -
            valueTransformers:
              -
                type: "constant"
                value: "-3"

Any takers on this yet?

The value transformers are recursive by nature, so you can compose them together. In this case, I would suggest to structure additional_image_link column value transformers like this:

• multipartString
  • multipartString (first link with "-1")
  • constant (separator)
  • multipartString (first link with "-3")
