ruby on rails - ActiveRecord Join table for legacy Database -

-

My legacy database is that I am working with ActiveRecord to work with I went into a problem with joining tables I have the following: 

  class TV show & lt; ActiveRecord :: Base set_table_name "tvshow" set_primary_key "idShow" and class episode & lt; ActiveRecord :: Base set_table_name "Episode" set_primary_key "idEpisode" end

And then I have a table called TVSolinkPeks with 2 fields: idShow, idEpisode so I have 2 tables and connect them (Many for many relationships), although it uses non-standard foreign keys. My first thought was to create a model called TV Shops Epicink, but not the primary key. The idea was that since foreign keys are non-standard then I can use set_foreign_key and I have some control. After all I'm TeeShosho I want to say something like (Previous). Episode or episode.fund (: last) .tv_show How do I get there?

I believe that you can be a little more beautiful than the answer to Alvaro. , Though its answer is perfectly fine and there will be very similar functionality for any client of your class. 

  class TvShow & lt; ActiveRecord :: Base set_table_name "tvshow" set_primary_key "idShow" has_and_belong_to_many: episode,: join_table = & gt; "TVSolink episode" ,: foreign_key => "IDShow" ,: association_foreign_key = & gt; "IDE Case" and Class Episode & lt; ActiveRecord :: Base set_table_name "Episode" set_primary_key "idEpisode" has_and_belong_s_many: tv_shows ,: join_table = & gt; "TVSolink episode" ,: foreign_key => "IdEpisode" ,: association_foreign_key = & gt; "IDSOW" and

Note that: The option of foreign_ specifies which column is on the "this side" of the square, while: association_foreign_key specifies that column The ID is the "On the Other Side" section of the link.

In contrast with Alvaro's answer, this pattern should not mean any unnecessary objects to represent the link.

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...
