Wildcard / Unmatched fields

[lorenzpfei]

Hi Tableflow team, thanks for your nice work!

I'm using csv-import to import a csv with a lot of columns. For future use, we want to save all unmatched columns into our db as well. Therefore, we need to receive all unmatched columns.

Is there a possiblity to get those columns? If not it would be nice, if we could get them via onSubmit as a second param or via a wildcard in the template which might be less clean.

@lorenzpfei thanks for the issue! I think this could work as an option to include the unmatched columns in the response.

@ciminelli I have a PR for this locally, it's pretty small. I'd be happy to share it and open a PR if you give me permission.

@DenisStad that sounds great, you can open a PR from your fork and I'll check it out.

👍 -- we need this too. Any timeline for when it will land? Great library!

If simpler, some different ways to allow this would also be to:

a) Allow the component to take the data as a parameter and go immediately to the "Select header" or "Map columns" page. As it is trivial for users to build their own file input components, this means they could pre-process the file and extract the column names (and perhaps do some necessary processing on them beforehand), and pass these column names and the data into the component so the user can map them properly.

b) Allow template to be a function which is passed the data upon CSV upload. This would be useful as we have a list of required columns but also want the user to provide other columns dynamically -- but they may only want to upload a subset of these, or we may want to exclude or special-case certain columns. Having a generic wildcard which uploads all other columns wouldn't allow this.
