    <p>How long are you programming with ruby? You have to create a new instance of your class to access the instance outside. Take a look at these basics: <a href="http://www.tutorialspoint.com/ruby/ruby_variables.htm" rel="nofollow">http://www.tutorialspoint.com/ruby/ruby_variables.htm</a></p> <p><strong>UPDATE</strong></p> <p>From the link above..</p> <p>Ruby Instance Variables:</p> <p>Instance variables begin with @. Uninitialized instance variables have the value nil and produce warnings with the -w option.</p> <p>Here is an example showing usage of Instance Variables.</p> <pre><code>class Customer def initialize(id, name, addr) @cust_id=id @cust_name=name @cust_addr=addr end def display_details() puts "Customer id #@cust_id" puts "Customer name #@cust_name" puts "Customer address #@cust_addr" end end # Create Objects cust1=Customer.new("1", "John", "Wisdom Apartments, Ludhiya") cust2=Customer.new("2", "Poul", "New Empire road, Khandala") # Call Methods cust1.display_details() cust2.display_details() </code></pre> <p>That´s how you can work with ruby and instance variables. More details are in the link.</p> <p>In your case I think you have another "error", you mixed a few things.. where is your helper class? Under the app/helpers/store_helper.rb? In this file you should just add view helpers. If I am right with my intuitions I would solve your problem like following:</p> <p>app/helpers/store_helper.rb</p> <pre><code>module StoreHelper def get_level_states(product) product_sales = product.line_items.total_product_sale.sum("quantity") product.volume2 = 0 if product.volume2.nil? product.volume3 = 0 if product.volume3.nil? levels = {} if (product_sales &gt;= product.volume2) &amp;&amp; (product_sales &lt; product.volume3) levels[:1] = "On!" levels[:2] = "On!" levels[:3] = "Active!" elsif product_sales &gt;= product.volume3 levels[:1] = "On!" levels[:2] = "On!" levels[:3] = "On!" else levels[:3] = "Pending" end levels end end </code></pre> <p>app/views/your_views_folder/your_view.html.erb</p> <p>to get the different level state:</p> <pre><code>&lt;% levels = get_level_states(product) %&gt; &lt;%= levels[:1] %&gt; # will print the level 1 &lt;%= levels[:2] %&gt; # will print the level 2 &lt;%= levels[:3] %&gt; # will print the level 3 </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
