Put inline HTML into variable

Question

Is there a way to put an inline HTML in a view into variable? Something like this:

<% t = content_to_var do %>
   <h1>The title</h1>
<% end %>

<% my_var = content_to_var do %>
   <p>Watch this fine results:</p>
   <table>
   <tr><td>Value 1.1</td><td>Value 1.2</td></tr>
   <tr><td>Value 2.1</td><td>Value 2.2</td></tr>
   <tr><td>Value 3.1</td><td>Value 3.2</td></tr>
   </table>
<% end %>

<%= render 'partial', { title: t, contents: my_var }

Please be aware that I know about absence of function named exactly "content_to_var". It is mentioned only for example.

I know about content_for and yield, but want to do the same through locals.

I do not like an idea to do

my_var = '<table><tr><td>Value 1.1</td><td>Value 1.2</td></tr></table>'.html_safe

It looks ugly.

Answer 1

In old versions of Rails you can do

<% t = capture do %>
  <h1>The title</h1>
<% end %>

Don't know about newer versions

Answer 2

Why not just render partials? That's what they are made for.

You could do something like:

<% t = render :partial => 'title', :title => 'The title' %>
<% my_var = render :partial => 'values', :values => @values %>

<% render :partial => {title: t, contents: my_var } %>

And for completeness, your _title.html.erb would look like

<h1><%= title %></h1>

Hope this helps.
