ruby on rails - Polymorphic Association with multiple associations on the same model -

-

I got a little confused about the polymorphic union. I need a paragraph model for a header image and multiple images, but I have to make an image model. To make the case more confusing, the image model is polymorphous (to allow other resources to keep multiple images).

I am using this link in my article model: 

  class paragraph & lt; ActiveRecord :: Base has_one: header_image ,: as = & gt; : Image is qualified_mine: picture, as in: => : Imageable end

Is this possible? Thank you.

Yes it is entirely possible.

You may have to specify the class name for header_image , because it can not be estimated. Include : Dependent = & gt; : 

  class paragraph & lt; If deleted, delete  also to ensure that images have been deleted. ActiveRecord :: Base has_one: header_image ,: as = & gt; : Image worthy ,: class_name = & gt; 'Image' ,: Dependent = & gt; : Has_many deleted: images, as in => : Image, Dependent = & gt; : End of end

then on the other end ... 

  class image & lt; ActiveRecord :: Base is_to: imageable ,: polymorphic = & gt; True end

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
