Hey I am trying to learn rails and following the rails tutorial. I am adding some elements to the apps style sheets using SCSS and this is what I am adding
/* miscellaneous */
.debug_dump {
clear: both;
float: left;
width: 100%;
margin-top: 45px;
@include box_sizing;
}
}
but when I go to view my it in a browser I receive this error
Mixin box-sizing is missing argument $boxmodel.
(in /Users/<mynamehere>/workspace/sample_app/app/assets/stylesheets/custom.css.scss:110)
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all",
"data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
Rails.root: /Users/<mynamehere>/workspace/sample_app
Any help would be much appreciated. Here is a link to my github if you need to see anything else

The error says, you need a argument for box_sizing.
So try @include box-sizing(border-box);.

I made the same mistake. Check again Listing 7.2, there's some extra code there before the "/* Miscellaneous */" part, where you declare what box_sizing is:
@mixin box_sizing {
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
