ios - NSOrderedSet is not convertible to NSManagedObject -

-

I'm partially following the tutorial with Ray Vendorlich (if you search for 'Save Run' This should jump in part about this question). I have also tagged it with 'swift', because I do not know that it is fast due to any problem (because it is working in the tutorial which is in Objisi).

I'm currently stuck on saving location data in the CoreData data model.

Code here for my saved session method: 

  func saveSession () {var newSession: session = NSEntityDescription.insertNewObjectForEntityForName ("Session", Managed Object Contex: Management Object Contains!) As the session new session.imestamp = NSDate () var tempArray = [AnyObject] () for self. Place newlocationArray {var location: location = NSEntityDescription.insertNewObjectForEntityForName ("Location", Managed Object Contact: Self.managedObjectContext!) As the location location. Timestamp = newLocation.Timestamp location.latitude = newLocation.coordinate.latitude location.longitude = newLocation.coordinate.longitude location .altitude = newLocation.altitude location. Title = new location Top Location Movement = NewLocation.hor IzontalAccuracy location.verticalAccuracy = newLocation.verticalAccuracy tempArray.append (location)} // This is a line generating error: // 'NSOrderedSet' is not variable for 'NSManagedObject' new session.locations = NSOrderedSet (array: tempArray)}   
 This is my data model:  
 session unit  session unit   
 location unit  location unit   
 Let me know if any more code / information is needed to solve it . Any help is greatly appreciated.  
  
 
 
 You defined the  locations  property "one-one" relationship "Many" relationships should be

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
