Trying to figure out generating html in controller

So I have some old code that used to work and I am trying to
resurrect it.

 The controller has this:

 @content=""
  for i in 0..w.size
    @content = @content + "<span id=\"w#{i}\"
style=''display:none''>
#{w[i]} </span>"
  end
  @content = "<div
style=\"font-size:100;color:blue;\">" + @content +
"</div>"

  @txt_divs = ""
  for i in 0..5
    span = ""
    for j in 0..10
      span = "#{span} <span id=''sp#{i}_#{j}''
style=''display:none''> </
span>"
    end
    div = "<div> #{span} </div>"
    @txt_divs << div << "\n"
  end




In the view I then do this:


<%= @content%>

<%= @txt_divs %>


but what''s get generated is this as literal text and not what I wanted
or what used to work:

&lt;div
style=&quot;font-size:100;color:blue;&quot;&gt;&lt;span
id=&quot;w0&quot; style=''display:none''&gt; Free
&lt;/span&gt;&lt;span
id=&quot;w1&quot; style=''display:none''&gt; Spirit
&lt;/
span&gt;&lt;span id=&quot;w2&quot;
style=''display:none''&gt; Boston
&lt;/span&gt;&lt;span id=&quot;w3&quot;
style=''display:none''&gt;  &lt;/
span&gt;&lt;/div&gt;

&lt;div&gt;  &lt;span id=''sp0_0''
style=''display:none''&gt; &lt;/
span&gt; &lt;span id=''sp0_1''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_2''
style=''display:none''&gt; &lt;/span&gt;
&lt;span
id=''sp0_3'' style=''display:none''&gt;
&lt;/span&gt; &lt;span id=''sp0_4''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_5''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_6''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_7''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_8''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_9''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp0_10''
style=''display:none''&gt; &lt;/span&gt;
&lt;/div&gt;

&lt;div&gt;  &lt;span id=''sp1_0''
style=''display:none''&gt; &lt;/
span&gt; &lt;span id=''sp1_1''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp1_2''
style=''display:none''&gt; &lt;/span&gt;
&lt;span
id=''sp1_3'' style=''display:none''&gt;
&lt;/span&gt; &lt;span id=''sp1_4''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp1_5''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp1_6''
style=''display:none''&gt; &lt;/span&gt;
&lt;span id=''sp1_7''

Seems like you should move that into the view if you can though...

Additionally, as you take Philip''s suggestion, you ought to consider
the
power of using partials:

http://guides.rubyonrails.org/layouts_and_rendering.html#using-partials

Specifically, check out section 3.4.5, "Rendering Collections"
