Accepting nested IDs in header object

[zoranlorkovic]

As often you need to get data from database and then export it in CSV, it would be very handy if we could put nested IDs in header object.

Example:
object = {name: Test, surname: Test, nested: {time: test}}

And our header object would look like:
header: [{id: 'name', title: 'First name' }, {id: 'surname', title: 'Last name'}, {id: 'nested.time', title:'My time'}]

Does this make sense?

Thanks @zoranlorkovic for the suggestion. Perhaps we also need to provide an option to overwrite the character used to separate key names as nested.time can actually be a key for someone.

Released as v1.6.0. Let me know if there's any issue 👍

Hi good day, I just tried

example object:  {
  name: 'SSL Certificate',
  stock: null,
  price: 3650,
  ProductCategory: { 
     name: 'All',
  }
 },
header = [
  { id: 'name', title: 'name' },
  { id: 'ProductCategory.name', title: 'category' },
  { id: 'price', title: 'price' },
  { id: 'stock', title: 'stock' },
 ];

but the category column always comes out empty.

Hi @kazeemOnis , you need to specify headerIdDelimiter: '.'. I didn't want to make . as a default value, as it had introduced a breaking change otherwise.

• headerIdDelimiter <string> (optional)

  Default: undefined. Give this value to specify a path to a value in a nested object.
