SAPUI5 get single property from JSON-Model -

-

I am currently trying to figure out how I got a sap.ui.model.json.JSONModel

In my main view: 

  var gConfigModel = new sap.ui.model.json.JSONModel (); Var getConfigCallback = function (config) {gConfigModel.setData (config); }; OController.getConfiguration (getConfigCallback); Console.log (gConfigModel);   
 In my controller:  
  getConfiguration: function (callback) {var sServiceUrl = "/ sap / opu / odata / sap / xxx / configurationSet (' Start ') "; Var config = {}; Callback; $ .getJSON (sServiceUrl) .done (function (data) {config = data.d; callback (config);}); },   
 In your console.log statement, I can see that the data passed from the backend successfully and successfully set to the JSON model. The value of my requirement attribute is editable in a variable.  
 console.log-statement  
 I already have gConfigModel Tried .getProperty ('/'), did not work. Attempted to use GConfigModel.oData .. How can I store it in a value?  
  Solution Comment:  If you capture data from backend, then you have to remember how long it will take. The data can later be available, hopefully in my case I added a 1 second timeout, later I can easily use the property  
  setTimeout (function () {console Log (gConfigModel.getProperty ('/ editable'));}, 1000);    
 
 
  
 
 
  & lt; Script src = "https: // Openui5.hana.ondemand.com/resources/sap-ui-core.js" id = "Sap-U-Bootstrap" Data-SAP-UI-Theme = "SAP_blueistrist" Data-SAP- UI-Libs = "SAPM"> & gt; & lt; / script & gt; & lt; script & gt; function getConfiguration (callback) {var sServiceUrl = "/ sap / opu / odata / sap / xxx / configurationSet ('Initialize') "; var config = {}; Var data = {" d ": {" _metadata ":" "," backup "": "01", "editable": "true"}}; SetTimeout ((function () {config = data; callback (config);}) (), 2000); }; Var gConfigModel = new sap.ui.model.json.JSONModel (); Var getConfigCallback = function (config) {gConfigModel.setData (config); Warning (gConfigModel.getProperty ("/ d / editable")); }; GetConfiguration (getConfigCallback); & Lt; / Script & gt;

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...
