    <p>I have a page in my rails application that shows a list of listings (paginated using will_paginate). I am trying to find a good gem to implement searching and sorting with the list on this page. The Ransack gem looked like what i needed but i'm running into an issue with it. This is what my code looks like right now with the Ransack gem.</p> <p>My model (didn't include the whole model, didn't want the validations and extra code to get in the way):</p> <pre><code>UNRANSACKABLE_ATTRIBUTES = ["id", "state", "show_email", "email", "show_phones", "primary_phone", "secondary_phone", "updated_at", "user_id"] def self.ransackable_attributes auth_object = nil (column_names - UNRANSACKABLE_ATTRIBUTES) + _ransackers.keys end </code></pre> <p>My controller action:</p> <pre><code>def index @search = Listing.search(params[:q]) @listings = @search.result.paginate(page: params[:page], per_page: 20, joins: "LEFT OUTER JOIN attachments ON listings.id = attachments.attachable_id", select: "listings.*, COUNT(attachments.id) AS photos", group: "listings.id", order: "listings.created_at DESC, listings.title ASC, listings.id DESC") @search.build_sort if @search.sorts.empty? end </code></pre> <p>My search form on the page:</p> <pre><code> &lt;div class="advanced-search"&gt; &lt;%= search_form_for @search do |f| %&gt; &lt;div class="search-by"&gt; &lt;div class="search-field"&gt; &lt;%= f.label :title_cont, "Title Contains" %&gt; &lt;%= f.text_field :title_cont %&gt; &lt;/div&gt; &lt;div class="search-field"&gt; &lt;%= f.label :description_cont, "Description Contains" %&gt; &lt;%= f.text_field :description_cont %&gt; &lt;/div&gt; &lt;div class="search-field"&gt; &lt;%= f.label :price_gteq, "Price Between" %&gt; &lt;%= f.text_field :price_gteq %&gt; &lt;%= f.label :price_lteq, "and" %&gt; &lt;%= f.text_field :price_lteq %&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="sort-by"&gt; &lt;%= f.sort_fields do |s| %&gt; &lt;%= s.sort_select %&gt; &lt;% end %&gt; &lt;/div&gt; &lt;div class="search-actions"&gt; &lt;%= f.submit "Search" %&gt; &lt;/div&gt; &lt;% end %&gt; &lt;/div&gt; </code></pre> <p>My route:</p> <pre><code>resources :listings do collection do match 'search' =&gt; 'listings#index', via: [:get], as: :search end end </code></pre> <p>With everything i have in place now i have been able to get the application to successfully search and sort the listings.</p> <p><strong>My question:</strong> The <code>sort_select</code> field is showing everything option that is "ransackable". Is there a way to make one attribute available for the searching, but <em>not</em> the sorting? For example i want the ability to search on the <code>description</code> attribute but it doesn't make any sense to include that attribute in the sorting. How can i use an attribute in one and not the other? Thanks for any help and let me know if my question is not clear enough.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
