I fetched a list of all events and try to match it with my current events about to be added, but it never matches and just add duplicates.
The code I used to fetch is from apple's document. Can anyone help?
http://developer.apple.com/library/ios/#documentation/DataManagement/Conceptual/EventKitProgGuide/ReadingAndWritingEvents.html#//apple_ref/doc/uid/TP40004775-SW1
Code from another tutorial (I scourged the net but couldn't find how to match events. the fetch predicates results title string comparison did not work)
http://neilang.com/entries/using-eventkit-in-ios/
I found out that one can save the eventstore event unique identifier immediately after saving. And with this identifier one can get the events back.

I have a plannerTask and in its Details it has a CheckList. I use it to programatically insert CheckListItems in it, and it all works like a charm when inserting or retrieving the tasks.
My problem arrives when I am going to insert a new CheckListItem and the CheckList already has 20 items. It returns a MaximumChecklistItemsOnTask (because it is forbidden to insert more than 20 items in a check list).
Solution could be to remove the oldest item, but I am not able to do it. I have tried this:
var elementToRemove = oldDetails.Checklist.Where(c => c.Value.IsChecked).OrderBy(c => c.Value.LastModifiedDateTime).First();
oldDetails.Checklist = oldDetails.Checklist.Where(c => c.Value.LastModifiedDateTime <> elementToRemove.Value.LastModifiedDateTime);
But it throws a casting error in the second line:
Unable to cast object of type
'WhereEnumerableIterator1[System.Collections.Generic.KeyValuePair2[System.String,Microsoft.Graph.PlannerChecklistItem]]'
to type 'Microsoft.Graph.PlannerChecklistItems'.
Which is the right way to remove the oldest element from the ChecklistItem?
UPDATE:
In first place I retrieve a plannerTask from the server. Then I get the details from this plannerTask. So oldDetails is a plannertaskdetails object (https://learn.microsoft.com/en-us/graph/api/resources/plannertaskdetails?view=graph-rest-1.0). Inside the plannertaskdetails object (oldDetails), I have the plannerchecklistitems object (oldDetails.Checklist): https://learn.microsoft.com/en-us/graph/api/resources/plannerchecklistitems?view=graph-rest-1.0.
If plannerchecklistitems were just a List, it would be as easy as list.Remove(item), but it is not a normal list, and that is why I am not able to remove the item.
UPDATE 2:
I have found this way to remove the item from oldDetails:
oldDetails.Checklist.AdditionalData.Remove(elementToRemove.Key)
But, the the way I send the changes to the server is this:
await graphClient.Planner.Tasks(plannerTask.Id).Details.Request().Header("If-Match", oldDetails.GetEtag).UpdateAsync(newDetails)
As it is a PATCH request (not a PUT one), I only have in newDetails the records that have changed, it is, the new records. How could I specify there that a record has been deleted from the list? Sorry if my English is not good enough to express myself properly, but what I mean is that newDetails is not the full list, it only contains the records that must be added and I do not know how to specify in that request that one record must be deleted.
Currently I'm using Eventstore (by Greg Young) for my company project. In my read model, I store the processed event ids, not the event name. How can I find the event in Eventstore using its Id?
I don't think this is possible currently. I think you have two choices:
in your read model store the stream and index, or the commit/prepare position of the event and then read the event from either the $all stream using the commit/prepare position or from the stream it was written to using the stream and index. This is probably the simplest.
Or create a projection in event store which indexes the events by their id and reprojects into a stream called, say, eventid-{event.id} then you can read directly from this stream.
The second is backwards compatible with your current read model, but I'm not sure is the right thing to do, as projections cause write amplification, and you probably need to make sure you exclude system events from being projected.
You can query the event using the following URL path. This will return the event and the last 20 events before it
{youreventstoredomain}:2113/web/index.html#/streams/$ce-{streamname}/{eventnumber}/backward/20
When doing a PurchaseOrderQuery in QBXML I am trying to get Quickbooks to only return purchase orders that are not yet processed (i.e. "IsFullyReceived" == false). The response object contains the IsFullyReceived flag, but the query object doesn't seem to have a filter for it??
This means I have to get every single Purchase Order whether or not it's received, then do the filtering logic in my application - which slows down Web Connector transactions.
Any ideas?
Thanks!
You can't.
The response object contains the IsFullyReceived flag, but the query object doesn't seem to have a filter for it??
Correct, there is no filter for it.
You can see this in the docs:
https://developer-static.intuit.com/qbSDK-current/Common/newOSR/index.html
This means I have to get every single Purchase Order whether or not it's received, then do the filtering logic in my application - which slows down Web Connector transactions.
Yep, probably.
Any ideas?
Try querying for only Purchase Orders changed or modified (ModifiedDateRangeFilter) since the last time you synced.
Or, instead of pulling every single PO, keep track of a list of POs that you think may not have been received yet, and then only query for those specific POs based on RefNumber.
Or, watch the ItemReceipt and BillPayment objects, and use that to implement logic about which POs may have been recently filled, since BillPayment andItemReceipt` objects should get created as the PO is fulfilled/received.
I have the following predicate:
let predicate = NSPredicate(format: "NOT (recordID in %#)", recordIDs)
-- recordIDs is an array of CKRecordID objects corresponding to the CKRecords on the device
...that produces a runtime error about the predicate. If I change the predicate format string to something else, the query runs fine. I have the "Query" checkbox checked for all the metadata for this record type in CloudKit.
According to CKQuery documentation:
Key names used in predicates correspond to fields in the currently evaluated record. Key names may include the names of the record’s metadata properties such as "creationDate” or any data fields you added to the record.
According to CKRecord documentation, these are the available metadata for querying:
recordID, recordType, creationDate, creatorUserRecordID, modificationDate, lastModifiedUserRecordID, recordChangeTag
You can use the creation date:
NSPredicate(format: "creationDate > %#", dateLastFetched)
After you pull the records down to the device and save them, save the dateLastFetched and use it for subsequent fetches.
Edit: Be sure to enable the creationDate query index on the CloudKit dashboard (it is not enabled by default like many other indexes)
This is an old question, so I'm not sure if it existed at the time, but the correct way to do this now is to use Apple's built-in server change token support.
Making a giant query including all existing record ID's on the device is going to be slow, and picking a date is going to be imprecise.
The right way to do this is to use CKFetchRecordZoneChangesOperation and pass in a CKServerChangeToken using the operation's configurationsByRecordZoneID property.
The first time you call, pass a nil change token. As records are received, CloudKit will call recordZoneChangeTokensUpdatedBlock with the latest change token. Persist the latest token so the next time you need records from the server, you can just pass in your most recent token and get only what's changed since then.

I am making a call to;
https://www.eventbrite.com/xml/organizer_list_events?id=MYID
and getting a collection of event returned. I am integrating this data into an internal event system.
However, periodically I will get a venue without an ID. This means I cant add the venue into the system as I have no way of checking for duplicates before it is imported.
Show the VenueID always be returned? If not, under what circumstances would it not be returned?
The venue Id will not be returned if there is no venue, e.g. if the event is a webinar / online only event or the venue is not yet chosen
