importation of values from text file

[lpatiny]

I have an text file that contains many results for the same product of elementAnalysis.

I would like therefore to add many entries in the table spectra -> elementAnalysis

This can be done usually using 'addAttachments' that allows to attach many files at once.

My problem is that I have no attachment. Each entry contains only the metadata and therefore the test of the attachment fails (no field, buffer, etc.). Would it possible to add a flag 'onlyMeta' or something like that ?

  for (let line of lines) {
    let metadata = {
      c: line[10],
      h: line[9],
      n: line[11],
      instrument: {
        model: '',
        manufacturer: ''
      }
    };

    const hash = md5(line).substring(0, 8);
    result.addAttachment({
      jpath: ['spectra', 'elementalAnalysis'],
      metadata,
      reference: hash // we ensure the unicity of the reference as well
    });
  }
