When using Kendo Scheduler to work with a SharePoint list I am able to display and edit item but running into an issue adding/creating a new item. I do not receive a javascript error when I save the item, but stepping through the done function in jquery, I do receive a bad request error.
When editing the record, a __metadata object exists in the data, but during a create, this item is missing. The __metadata object contains the url and other important information.
When I stringify the edit call the data looks like this: "{\"__metadata\":{\"id\":\"Web/Lists(guid'2abecf66-35ed-4c67-b1f1-8b7255ebf0e2')/Items(2)\",\"uri\":\"https:///_api/Web/Lists(guid'2abecf66-35ed-4c67-b1f1-8b7255ebf0e2')/Items(2)\",\"etag\":\"\\"4\\"\",\"type\":\"SP.Data.6001C5110ListItem\"},\"Author\":{\"__metadata\":{\"id\":\"e10cdb3d-b3da-4f1f-8a64-fca71ddeafa9\",\"type\":\"SP.Data.UserInfoItem\"},\"Id\":5,\"Title\":\"User name here>\"},\"Id\":2,\"ID\":2,\"Title\":\"6001-C5-110 Test 2 A\",\"Start1\":\"2018-11-19T17:00:00.000Z\",\"OData__x0045_nd1\":\"2018-11-19T19:00:00.000Z\",\"RecurrenceRule\":null,\"RecurrenceParentID\":null,\"CategoryDescription\":\"Test2\",\"IsAllDay\":false}"
The create looks like this: "{\"startTimezone\":\"\",\"endTimezone\":\"\",\"recurrenceException\":\"\",\"ID\":null,\"Title\":\"No title\",\"Start1\":\"2018-11-06T05:00:00.000Z\",\"OData__x0045_nd1\":\"2018-11-06T05:00:00.000Z\",\"RecurrenceRule\":\"\",\"RecurrenceParentID\":0,\"CategoryDescription\":\"\",\"IsAllDay\":true}"
I would think the __metadata tag is necessary. The message I get back from the server when the create is attempted is
"{\"error\":{\"code\":\"-1, Microsoft.SharePoint.Client.InvalidClientQueryException\",\"message\":{\"lang\":\"en-US\",\"value\":\"An entry without a type name was found, but no expected type was specified. To allow entries without type information, the expected type must also be specified when the model is specified.\"}}}"
As I mentioned, I receive a Bad Request error in jquery.
Here is my scheduler code:
$("#scheduler").kendoScheduler({
date: new Date("2018/11/11"),
startTime: new Date("2018/11/11 07:00 AM"),
height: 600,
views: [
"day",
"workWeek",
"week",
{ type: "month", selected: true },
"agenda",
{ type: "timeline", eventHeight: 50}
],
save: function (e)
{
// alert('scheduler save');
},
dataSource: {
transport: {
read: {
url: "https://<ShrePoint Site Collection>/_api/web/lists/getbytitle('6001-C5-110')/items?$expand=Author&$select=Author/Id,Author/Title,ID,Title,Start1,OData__x0045_nd1,RecurrenceRule,RecurrenceParentID,CategoryDescription,IsAllDay&$filter=Start1 ge datetime'2018-11-01T00:00:00Z'",
//url: "https://demos.telerik.com/kendo-ui/service/tasks",
beforeSend: function (xhr) {
xhr.setRequestHeader("Accept", "application/json; odata=verbose");
},
},
update:

},

headers: {
"accept": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val(),
"If-Match": "*",
"X-HTTP-Method": "MERGE",
},
},
create: {
// The create function should perform a similar routine as the update one with a couple of notable differences:
// •The newly created data items have no ID, so they must be added by the function script or returned by the remote service.
// •The newly created data items must be returned in the success method with their IDs assigned. Otherwise, the DataSource
// instance is going to operate with incorrect data and subsequent data operations can fail.
// •If the schema.data configuration is set, the success method should receive the created data item in an object
// with the same structure as the object that is passed to the success method of the read function. See the example below.
url: function (data) {
return "https://<SharePoint Site collection>/_api/web/lists/getbytitle('6001-C5-110')/items";
},
type: "POST",
dataType: "json",
contentType: "application/json;odata=verbose",

alert('Success!');
},
error: function (error) {
alert('Error!');
console.log(JSON.stringify(error));
},
},
save: function (e)
{
alert('saving');
},
parameterMap: function (data, type) {
return kendo.stringify(data);
}
},
schema: {
data: function (data) {
return data.d && data.d.results ? data.d.results : [data.d];
},
model: {
id: "id",
fields: {
id: { from: "ID", type: "number" },
title: { from: "Title", defaultValue: "No title", validation: { required: true } },
start: { type: "date", from: "Start1" },
end: { type: "date", from: "OData__x0045_nd1" },
recurrenceRule: { from: "RecurrenceRule" },
recurrenceId: { from: "RecurrenceParentID", type: "number" },
description: { from: "CategoryDescription" },
isAllDay: { type: "boolean", from: "IsAllDay" }
}
}
}
}
});
Thank you for your time!
