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         


        

Answer 1

It seems that passing a formats option will render it properly in newer Rails version, at least 3.2:

{
  someKey: 'some value',
  someHTML: "<%= h render('baz', formats: :html) -%>"
}
