Runtime Schema

Do you need to import data in columns that are not fixed firsthand? Impler provides a facility to provide schema at the moment of opening the import widget.

Available after the impler version 0.9.1

Purpose

Consider you have an ERP application that needs to import sales information. Our system provides a way to add extra information to sales information, like challan-no. Other users might have different columns.

In that case, fixing the import data structure is impossible. So we need to pass schema during run time when the user clicks on Import button to import the data.

You can find relevant implementation for react in Providing Runtime Schemaand for HTML & HS in Providing Runtime Schema

Example Schema

[
  {
    name: 'Name',
    key: 'name',
    type: 'String'
  },
  {
    name: 'Phone',
    key: 'phone',
    type: 'Number',
    defaultValue: '#########'
  },
  {
    name: 'Country',
    key: 'country',
    type: 'String'
  }
]
