Return flat object from sequelize with association

Question

I am working on converting all my queries in sequelize. The problem I have come across is that when select queries include associations (ex. one to many), the object I get

Answer 1

Using raw: true a helper function can simplify the return keys. This will make sure no values are over-written and gives a way to keep some of string-based nesting (IDs for example).

/**

  @example result.map(r => trimKeys(r))
*/
function trimKeys(obj, deepin = ['id']) {
  const keys = Object.keys(obj)
  const ret = {}
  for (var i = 0; i < keys.length; i++) {
    const key = keys[i]
    const keyParts = key.split('.')
    let idx = 1
    let newKey = keyParts[keyParts.length - idx]
    while((ret[newKey] || deepin.find(d => newKey === d)) && idx >= 0) {
      idx++
      newKey = keyParts[keyParts.length - idx] + '.' + newKey
    }
    ret[newKey] = obj[key]
  }
  return ret
}
