    copied!<p>I have an application with a list of majors and each one is tagged with categories using the acts-as-taggable-on gem. I have a page where you can explore majors by category. So, you see the categories and grouped under the category is a list of the majors. </p> <p>My <code>categories_controller.rb</code> file: </p> <pre><code>def index @creative = Major.tagged_with("creative arts") @engineering = Major.tagged_with("engineering and technology") @mechanics = Major.tagged_with("mechanics and construction") @transportation = Major.tagged_with("transportation") @science = Major.tagged_with("science") @math = Major.tagged_with("math") @resources = Major.tagged_with("natural resources") @healthcare = Major.tagged_with("health care") @social_sciences = Major.tagged_with("social sciences") @education = Major.tagged_with("education") @law = Major.tagged_with("law") @management = Major.tagged_with("management and marketing") @administrative = Major.tagged_with("administrative and clerical") @services = Major.tagged_with("services") @tags = Major.tag_counts end </code></pre> <p>You can see the duplication. This is compounded on the view template. </p> <p>Here's part of the <code>index.html.erb</code> page: </p> <pre><code>&lt;!-- Creative Arts --&gt; &lt;h2 class="major-categories-landing"&gt;Creative Arts&lt;/h2&gt; &lt;% @creative.sample(10).each do |creative| %&gt; &lt;%= link_to creative, class: 'span2 category-landing' do %&gt; &lt;%= image_tag creative.image(:similar), class: 'img-polaroid', id: 'category-landing-list' %&gt; &lt;p class="category-landing-list-name"&gt;&lt;%= creative.name %&gt;&lt;/p&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;%= link_to "View all #{@creative.count} majors in this category.", category_path("creative arts"), class: "view-category-show-page" %&gt; &lt;!-- Social Sciences --&gt; &lt;h2 class="major-categories-landing"&gt;Social Sciences&lt;/h2&gt; &lt;% @social_sciences.sample(10).each do |ss| %&gt; &lt;%= link_to ss, class: 'span2 category-landing' do %&gt; &lt;%= image_tag ss.image(:similar), class: 'img-polaroid', id: 'category-landing-list' %&gt; &lt;p class="category-landing-list-name"&gt;&lt;%= ss.name %&gt;&lt;/p&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;%= link_to "View all #{@social_sciences.count} majors in this category.", category_path("social sciences"), class: "view-category-show-page" %&gt; </code></pre> <p>and so on for each category. I have tried <code>@category = Major.tagged_with(params[:tag])</code> and many variations to that to no avail. This is my first time working with acts_as_taggable_on and although I've read the documentation over and over I can't quite figure this out. </p> <p>I hope to extend this out throughout the application and so I want to figure it out now before I get a lot duplicate code. Thanks for sharing any ideas or suggestions!!</p> <p>I am running a rails 3.2.11 app. </p> <p><strong>UPDATE</strong><br> Here's how much better this is now:<br> My <code>categories_controller.rb</code> file: </p> <pre><code>def index @major_categories = ["creative arts", "social sciences", "science", ....] end </code></pre> <p>My <code>index.html.erb</code> page: </p> <pre><code>&lt;% @major_categories.each do |c| %&gt; &lt;!-- Title and blue strip --&gt; &lt;div class="category-strip"&gt; &lt;div class="container"&gt; &lt;h2 class="major-categories-landing"&gt;&lt;%= c %&gt;&lt;/h2&gt; &lt;/div&gt; &lt;/div&gt; &lt;!-- Show Each Major in this Category --&gt; &lt;div class="container"&gt; &lt;div class="row-fluid"&gt; &lt;% Major.tagged_with(c).order('RANDOM()').limit(10).each do |major| %&gt; &lt;%= link_to major, class: 'span2 category-landing' do %&gt; &lt;%= image_tag major.image(:similar), class: 'img-polaroid' %&gt; &lt;p class="category-landing-list-name"&gt;&lt;%= major.name %&gt;&lt;/p&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;/div&gt; &lt;!-- Link to View All Majors --&gt; &lt;div class="row-fluid"&gt; &lt;div class="view-all-category"&gt; &lt;%= link_to "View all #{Major.tagged_with(c).count} majors in this category.", category_path(c), class: "view-category-show-page" %&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre>
