Write Ruby code inside TinyMCE textbox

Question

Is it possible to write Ruby code inside the TinyMCE textbox? I've tried accessing some model data by putting <%= foo.bar %> inside a TinyMCE textbox but when rendering the raw text it displays the Ruby code as is - it doesn't render the Ruby code, just treats it as part of the text.

I've tried the raw and html_safe methods but neither worked.

Any suggestions?

Edit: I'm using the tinymce-rails gem and the following is the code in my form:

  <td><%= section_form.text_area :html, class: "tinymce", style: "width:800px; height:300px;" %></td>
  <%= tinymce content_css: asset_path('tiny_mce_content.css') %>

How are you trying to add your text to tinymce? stackoverflow.com/questions/488189/… may be relevant. Are you using tinyMCE.activeEditor.setContent? — Puhlze

Just run it through ERB, e.g:

ERB.new("<%= 'something'.upcase %>").result
=> "SOMETHING"

If you're looking to pass variables in, check out this post, which has a few options: Ruby templates: How to pass variables into inlined ERB?

Unfortunately the code above doesn't display the Ruby code any different. It's still not returning the object - just the text. I tried <% foo = ERB.new("<%= current_profile.name %>").result %> then displaying foo; I also tried <% foo = ERB.new("<%= current_profile.name %>").result(namespace.instance_eval { binding }) %> and then displaying foo but both ways give me a syntax error: syntax error, unexpected keyword_class, expecting keyword_do or '{' or '('.

@mmichael Yes, unfortunately this doesn't get you access to the current variable scope. You have to jump through some hoops-- take a look at the post I linked to in the answer.

I'll take a closer look. Thank you for your response. I'll give it another go tomorrow.
