ruby on rails - Why is my view file moving all my head content into the body section? -


i'm confused how application.html.erb file , view files combine. have in application.html.erb file following (minimized content brevity):

<!doctype html> <html>   <head>     <!-- bootstrap css -->     <link href="/bootstrap-assets/css/bootstrap.css" rel="stylesheet">     <%= yield :head %>   </head> <body>    <nav>       <!--long navbar section -->    </nav>   <%= yield %> </body> </html>

in view file:

<html> <head>     <!-- view specific stylesheet -->     <link href="/css/viewspecific.css" rel="stylesheet" /> </head> <body>     <!-- view specific body --> </body>

what expect when these 2 files combine, view specific stylesheet load in <head> section, , view specific body load in <body> section. final result sends view specific stylesheet <body> section, after navbar application.html.erb loaded. produces unwanted result part of body loading before stylsheet loaded, , first second user views page looks terrible.

you should make use of content_for if want render view-specific head head section of application.html.erb. use

<% content_for :head %>  <!-- view specific head section -->   <link href="/css/viewspecific.css" rel="stylesheet" /> <% end %>

since yield :head in application.html.erb, thats done. , don't need html tags in views.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
