Transport.create

configuration

The configuration used when the data source saves newly created data items. Those are items added to the data source via the add or insert methods.

The data source uses jQuery.ajax to make an HTTP request to the remote service. The value configured via transport.create is passed to jQuery.ajax. This means that you can set all options supported by jQuery.ajax via transport.create except the success and error callback functions which are used by the transport.

If the value of transport.create is a function, the data source invokes that function instead of jQuery.ajax. Check the jQuery documentation for more details on the provided argument.

If the value of transport.create is a string, the data source uses this string as the URL of the remote service.

The remote service must return the inserted data items and the data item field configured as the id must be set. For example, if the id of the data item is ProductID, the "create" server response must be [{ "ProductID": 79, "AnotherProperties": "value"}] including the ID and the other properties of the data items.

All transport actions (read, update, create, destroy) must be defined in the same way, that is, as functions or as objects. Mixing the different configuration alternatives is not possible.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      url: "https://demos.telerik.com/service/v2/core/products/create",
      type: "POST",
      contentType: "application/json"
    },
    parameterMap: function(data, type) {
      if (type == "create") {
        // send the created data items as the "models" service parameter encoded in JSON
        return kendo.stringify(data.models);
      }
    }
  },
  batch: true,
  schema: {
    model: { id: "ProductID" }
  }
});
// create a new data item
dataSource.add( { ProductName: "New Product" });
// save the created data item
dataSource.sync(); // server response is [{"ProductID":78,"ProductName":"New Product","UnitPrice":0,"UnitsInStock":0,"Discontinued":false}]
</script>

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    read: function(options) {
      /* implementation omitted for brevity */
    },
    create: function(options) {
      $.ajax({
        url: "https://demos.telerik.com/service/v2/core/products/create",
        type: "POST",
        contentType: "application/json",
        data: kendo.stringify(options.data.models),
        success: function(result) {
          // notify the data source that the request succeeded
          options.success(result);
        },
        error: function(result) {
          // notify the data source that the request failed
          options.error(result);
        }
      });
    }
  },
  batch: true,
  schema: {
    model: { id: "ProductID" }
  }
});
dataSource.add( { ProductName: "New Product" });
dataSource.sync();
</script>

If set to false, the request result will not be cached by the browser. Setting cache to false will only work correctly with HEAD and GET requests. It works by appending "_={timestamp}" to the GET parameters. By default, "jsonp" requests are not cached.

Refer to the jQuery.ajax documentation for further information.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      cache: true
    }
  }
});
</script>

transport.create.contentType

String

The content-type HTTP header sent to the server. The default is "application/x-www-form-urlencoded". Use "application/json" if the content is JSON. Refer to the jQuery.ajax documentation for further information.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      contentType: "application/json"
    }
  }
});
</script>

transport.create.data

Object|Function

Additional parameters that are sent to the remote service. The parameter names must not match reserved words, which are used by the Kendo UI DataSource for sorting, filtering, paging, and grouping.

Refer to the jQuery.ajax documentation for further information.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      data: {
        name: "Jane Doe",
        age: 30
      }
    }
  }
});
</script>

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      data: function() {
        return {
          name: "Jane Doe",
          age: 30
        }
      }
    }
  }
});
</script>

transport.create.dataType

String

The type of result expected from the server. Commonly used values are "json" and "jsonp".

Refer to the jQuery.ajax documentation for further information.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      dataType: "json"
    }
  }
});
</script>

transport.create.type

String

The type of request to make ("POST", "GET", "PUT" or "DELETE"). The default request is "GET".

The type option is ignored if dataType is set to "jsonp". JSONP always uses GET requests.

Refer to the jQuery.ajax documentation for further information.

Default: "GET"

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      /* omitted for brevity */
      type: "POST"
    }
  }
});
</script>

transport.create.url

String|Function

The URL to which the request is sent.

If set to a function, the data source will invoke it and use the result as the URL.

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      url: "https://demos.telerik.com/service/v2/core/products/create",
      cache: true,
      type: "POST",
      contentType: "application/json"
    },
    parameterMap: function(data, type) {
      if (type == "create") {
        return kendo.stringify(data.models)
      }
    }
  },
  batch: true,
  schema: {
    model: { id: "ProductID" }
  }
});
dataSource.add( { ProductName: "New Product" });
dataSource.sync();
</script>

<script>
var dataSource = new kendo.data.DataSource({
  transport: {
    create: {
      url: function(options) {
        return "https://demos.telerik.com/service/v2/core/products/create"
      },
      cache: true,
      type: "POST",
      contentType: "application/json"
    },
    parameterMap: function(data, type) {
      if (type == "create") {
        return kendo.stringify(data.models)
      }
    }
  },
  batch: true,
  schema: {
    model: { id: "ProductID" }
  }
});
dataSource.add( { ProductName: "New Product" });
dataSource.sync();
