angularjs - Capture the original value of an Angular model for in-place editing -

-

I have created a simple in-place editing solution for profile data in my app. The problem is, if a person Edits and modifies the text of that field, but due to the binding of the coonors, the change in text is still displayed in the UI to select "Cancel".

I was thinking that when someone "edits the profile", then I capture the original value of the ground so that if it is canceled, then it can restore the original text . 

  $ scope.editProfile = - & gt; $ Scope.editState = true $ scope.originalDescription = $ scope.user.profile.description   
 Of course, something that does not work is $ scope.user.profile.description at that time I want to edit when the Edit profile file is called.  
 Any suggestions for strategies here?   
 
 
 what you can do, is this:  
  angular copy ($ Scope.user.profile.description, $ scope.description.backup)   
 and if you need to restore the original values:  
  Angular.copy ($ scope.description.backup, $ scope.user.profile description)

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...
