postgresql - Rails before_destroy callback db changes always rolled back -

-

I am trying to remove the model from DB and it is too much to follow (see 9.2.5.3 Exercise < P>

I have a simple model: 

  class user & lt; ActiveRecord :: base before_destroy update_attribute (: deleted_at, Time.current) incorrect end  >

and in the controller: 

  Delete def @ user = user # # User.update! (Deleted_at: time.zone.now) #If I do it So it works at user.destroy @ # if I also comment on this line ... render: sh End

Callback is called and the attribute is set, but then the database transaction is always rolled back. I leave it because I false The model is removed because the deletion execution is not stopped.

As you can see in the comments, I can find it to work, but do I actually have a service object To use So my logic and I want out of the controller.

If your callback incorrectly transmits the transaction will always be rollbacked.

Whatever you want, you should not call the destroy method on your escale object. Instead, make your own method like soft_destroy or something else to update your feature.

And to prevent others from calling the destroy method on their arel objects, just add a callback, for example, raising and exception.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
