title: Render ajax query in Rails
body: <p>I am tryign to render an Ajax query , but I just dont figure out how.</p>
  
  <p>This is the form:</p>
  
  <pre><code>&lt;%= form_tag(root_path, :method =&gt; "post",:id =&gt;"formid", :remote =&gt; true) do %&gt;
    &lt;%= label_tag(:number1, "El que quiero") %&gt;
    &lt;%= text_field_tag :quiero, nil, :class =&gt; 'drug_autocomplete' %&gt;
    &lt;%= hidden_field_tag :number1 %&gt;
  
    &lt;%= label_tag(:number1, "El modelo que tengo") %&gt;
    &lt;%= text_field_tag :tengo, nil, :class =&gt; 'drug_autocomplete' %&gt;
    &lt;%= hidden_field_tag :number2 %&gt;
  
    &lt;%= label_tag(:size1, "Talla de el que tengo") %&gt;
    &lt;%= text_field_tag :size1%&gt;
  
    &lt;%= submit_tag("Do it!",:id =&gt;"submit_but") %&gt;
  
  &lt;% end %&gt;
  </code></pre>
  
  <p>This is pretty much the controller</p>
  
  <pre><code>def index
      size1 = params[:size1]
      number1 = params[:number1]
      number2 = params[:number2]
      quiero = params[:quiero]
      tengo = params[:tengo]
  
  if (item1 and item2)
  
        @itemsok = Contribution.where("first_item_id = ?",item1.id).where("second_item_id = ?",item2.id).where("second_item_grade = ?",size1)
  
        end
  </code></pre>
  
  <p>Ok, so when I push the button to send, I can see that the consult in the database is being made, when I write correct values it returns it and all works perfectly.</p>
  
  <p>What I dont know how to do is to render the items from the query.
  In the view I have a table where I want to fill the information in...
  I've already done it without AJAX, and it is like this.</p>
  
  <pre><code>&lt;%if not @itemsok.nil? 
    @itemsok.each do |searches|
  %&gt;
  &lt;table&gt;
  &lt;tr&gt;
    &lt;td style="width:100px;"&gt;&lt;%= searches.first_item.description %&gt;  &lt;/td&gt;
    &lt;td style="width:150px; font-size:30px;"&gt;&lt;%= searches.first_item_grade %&gt;  &lt;/td&gt;
  
  
    &lt;td style="width:150px;"&gt;&lt;%= searches.second_item.description %&gt; &lt;/td&gt;
    &lt;td style="width:150px; font-size:30px;"&gt;&lt;%= searches.second_item_grade %&gt;  &lt;/td&gt;
    &lt;td style="width:150px; font-size:18px;"&gt;&lt;a href="&lt;%= contribution_path(searches.id) %&gt;"&gt;Show&lt;/a&gt;  &lt;/td&gt;
  
  
  &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Ok, so it takes the variable in the controller, and if is not nill, it renders the data (wich in a normal request, I can access reloading the page)</p>
  
  <p>How can I render the items from my query?
  Any hint would be very appreciated.
  Thank you.</p>
