alter

Will change property names of the current-data to fit the required template placeholders.

Fields

  { 
      do      : 'alter'
    , data    : changes
    , select ?: items 
  }

Types

• items: string | number | Array < string | number >. Represent elements in the list. There are few predefined values: 'first','last','all'. Use number to define element from start to end or (-number) from end to start. Missing selection param is equal to: select: ['all']
• changes: { before : after }, where before is actual property name that will be renamed to after.

Example

  { do: 'alter', data: {'user':'text'} }

If current-data has item { user: 'Peter' }, item will be converted to {text: Peter} in order to fit template requirements - existing template placeholders.
