How to render erb template to string inside action?

Question

I need a string of html (something like \"Hello World\") for faxing purpose.

I wrote it into a seprat

Answer 1

The reason is you cannot render or redirect inside the same action more than once at a given time.

But in your code, you have both render and redirect. I think in your controller you can use simply only the render, assuming you don't need any json output.

Try this

def create
  @order.save   
  render(:partial => 'fax')
end

I haven't tested this, but I guess you get the idea :), and think about a way to handle errors as well (in case order didn't save).
