Question

Is it possible to respond a json request with html instead of json?

I would like to do this:

respond_to do |format|
  format.html { render 'page' }
  format.json { render 'page' } #render an html page instead of a JSON response
end

but Rails will search for a ‘page.json’ and will throw an error.

Answer 1

You need to explicitly set format, content-type (default is application/json) and layout (default is none):

respond_to do |format|
  format.html { render 'page' }
  format.json do              # render an html page instead of a JSON response
    render 'page.html', {
      :content_type => 'text/html',
      :layout       => 'application'
    }
  end
end
