deep map keys? #26

Closed masciugo closed 4 years ago

masciugo commented 5 years ago

How can I deeply transform keys with deepdash?

YuriGor commented 5 years ago

Hi, currently there is no such method, I'll think about adding it in future release, when I'll have a bit of free time. If you need it right now you can use reduceDeep instead

For the sake of completeness, a specific method would be the best solution. But this is my implementation, which is quite satisfying 

mapDeep( obj, (value, key, parentValue, context) => {
  if (_.isPlainObject(value)) {
    return _.mapKeys(value, (v,k) => {
      switch (k) {
        case 'id':
          return 'value'
        case 'name':
          return 'label'
        default:
          return k
      }
    })
  } else {
    return value
  }
})

Looks like I've chosen the wrong name for mapDeep. It actually should be mapValuesDeep, same as in lodash for one preserving object structure to be pair for mapKeysDeep requested above. And mapDeep is the correct name for 'collectDeep' planned in #42

done in v5,0,0 (that was tricky :sweat_smile:) mapKeysDeep also "old" mapDeep was renamed to mapValuesDeep and implemented again to return just array
