 & Lt; Strong & gt; Coming soon. & Lt; / Strong> & Lt; / H1> & Lt; Br> & Lt; Br> & Lt; P & gt; & Lt; B & gt; Name: & lt; / B & gt; ** & lt;% = @ product.name% & gt; ** & lt; / P & gt; & Lt; / Div & gt; & Lt; / Div & gt;

  Model   
 product.rb  
  class product & lt; ActiveRecord :: Base attr_accessible: name,: photo end   
  controller   
 products_controller.rb  
  Class Product Controller & lt; ApplicationController def Show @ Product = Product.Fund (Parameters [: ID]) End Def Index = Products = Product.All End End    
 
 
 You are providing the  index  template with the  index  operation in your scope so that  @product  < Code> none . You must present partially in the loop with each product.  
  index.html.erb  should be something like this:  
  & lt; Div class = "row" & gt; & Lt;% @ products.each do | Products | & Gt%; & Lt; Div class = "span3" & gt; & Lt;% = Render: Partial = & gt; "Show",: Local => {: Product = & gt; Product}%> & Lt; A href = "# myModal" role = "button" data-toggle = "model" & gt; & Lt;% = (image_tag product.photo (Medium))% & gt; & Lt; / A & gt; & Lt; / Div & gt; & Lt;% end% & gt; & Lt; / Div & gt;
