Add copy paste capability on packaging + tags fields

[alexgarel]

Currently, on the web site:

• you can't copy/paste packaging data from one product to another
• you can't copy tags values in the fields

Proposal:

• add a copy icon next to tags fields and in the packaging fields
  • when clicked, it copies the value of field in CSV form in the clipboard
  • for tags: values separated by comma
  • for packaging: one item per line for packaging, and values separated by commas for each item
• this already enables pasting tags fields (as they accept a list of comma separated values)
• for packaging, add a paste button to fill packaging items from the CSV in clipboard (might be the hardest to do)
  • it should not care about "merging" existing values (user will remove them)

This should all be supported by javascript.

This issue is stale because it has been open 90 days with no activity.

I had a quick look at this and I found the whole packaging area quite hard to understand. For example, if I have said that the packaging is a "Tetra Brik Aspetic", do I still need to list the individual parts of the packaging, like the cap, or is that double-counting?

I think we should therefore be a bit cautious about prolifically "copying and pasting" data as one incorrect entry could then potentially corrupt many others without any kind of audit trail. I would suggest the following enhancement to this idea to help mitigate this:

1. If packaging data is copied from one product (source) to another (target) then store the source product id against the target product, and add the target product id to a list on the source product. Maybe want to include a timestamp for when the data was copied
2. If the product data is subsequently edited, create a data quality tag to indicate there may also be a problem with other product data if the product has a "copied from" product id or has any "copied to" product ids. Also make sure that a specific timestamp is stored for packaging edits

As discussed yesterday, as the process will probably be done by an advanced contributor, I don't think there will be so much mistakes.
