ruby on rails - Activerecord error .include? nil -

-

I am writing a rail app, in which there are some modules and methods loaded through Lib Libretti, I have also added trusted authentication modules, now every time I run using the mongrel server on production, I do not get this error, although because model classes and controller classes are cached, but in development I get this error , First place After that, I get the right treatment after development and running, but when I refresh the page, I get this error, whereas it shows that there is a need for a blue to be repeated in every method, I There are also some homework, as I said method, for all the methods of that example, for example, I do not have any method definitions such as ID, name, title for the table attributes Purchaser. I am unsure about this,

I am using Rails 2.2.2 and Ruby 1.8.7. Server mouth & amp; Webrick

This situation occurred to me, where I get the error after refresh (i.e. Second call).

It is possible that you have defined a module in your / lib directory that does not match the Rail Names of File Naming. And you're using the "filename.rb" statement to get the module.

Try using requires_dependency "filename.rb" instead.

Tell me if the problem still exists, then we can look deeply.

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...

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...
