3197 :: Error: cannot instantiate: 'OrderedTable'

  I get a compiler error for the following code. Anyone know what I am doing wrong?

  from tables import OrderedTable, toOrderedTable
  
  proc getMetaInfo(filename: string, fileSize: int64): OrderedTable =
    result = {
      "filename": filename,
      "size": fileSize,
    }.toOrderedTable
  
  var testing = getMetaInfo("filename", 44)
  Run

  sflennik: your code is wrong, OrderedTable can't contain different types It should be like this:

  from tables import OrderedTable, toOrderedTable
  
  proc getMetaInfo(filename: string, fileSize: int64): OrderedTable[string, string] =
    result = {
      "filename": filename,
      "size": $fileSize,
    }.toOrderedTable
  
  var testing = getMetaInfo("filename", 44)
  Run

  Thank you, that helps. I'm now looking at the json module.
