Rails 4: render ERB from database into string

Question

I have stored the content of a .html.erb file in the database. I now want to render the ERB data into a string without displaying it. I tried

rendered = render_to_string(:template => MailTemplate.find(1).body)

but it throws Missing template. Does the render_to_string method only work with an actual file?

You need to tell render to use a text string, not a template.

rendered = render_to_string(:text => MailTemplate.find(1).body)
