How do I render a partial of a different format in Rails?

Question

I\'m trying to generate a JSON response that includes some HTML. Thus, I have /app/views/foo/bar.json.erb:

{
  someKey: \'some value\',
  someH

Just elaborating on what zgchurch wrote:

• taking exceptions into account
• returning the result of the called block

Thought it might be useful.

def with_format(format, &block)
  old_formats = formats
  begin
    self.formats = [format]
    return block.call
  ensure
    self.formats = old_formats
  end
end
