我无法在谷歌上找到它.我有3个型号.

模型1 - > has_many模型2 - >有很多模型3

模型1具有用于确定可以创建多少模型2的字段.和模型2有字段来知道必须创建多少模型3.

我想保存模型1时,自动创建模型2和模型3.

我想从模型1中使用after_create create_model2_record

def create_model2_record
  for(x=0, x<=model1.field; x++){  #c sample
    @model2 = Model2.new
  }
end 

怎么用rails 3来处理这个？thansk

我的prod actionmailer有问题.我托管在site5共享云上.问题是我收到此错误消息.

我尝试做的WinMain出了问题.我在Windows C++编程中完全是noob,我试着学习.我跟着一个tutoriel来帮助我.但是看起来不行!这是我的代码..

    ZeroMemory(&wc, sizeof(WNDCLASSEX));

    wc.cbSize = sizeof(WNDCLASSEX);
    wc.style = CS_HREDRAW | CS_VREDRAW;
    wc.lpfnWndProc = WindowProc;
    wc.hInstance = hInstance;
    wc.hCursor = LoadCursor(NULL, IDC_ARROW);

    wc.lpszClassName = "WindowClass1";

    RegisterClassEx(&wc);
