Hi

I have vacancies, I want to recommend, and if wanted directly attache  
as pdf.

You get the PDF with e.g. /vacancies/9887.pdf  
How can I attach some thing in a mail?

Whats the best pratice here?  
Sending through Rack?  
Streaming / self calling HTTP URI and attach it?

I tried even to do something like this:

# Forward via Email

def forward  
render\_to\_string :action =\> “show”  
pdf = response.body  
@vacancy = Vacancy.find\_by\_vacancy\_number(params[:vacancy\_number])  
if NotificationMailer.recommendation(@vacancy, params[:email],  
(params[:pdf] == ‘true’), params).deliver  
flash[:notice] = ‘The Job offer has been sent.’  
else  
flash[:notice] = ‘The Job offer could not be sent’  
end  
redirect\_to :action =\> :show, :id =\> params[:vacancy\_number]  
end

Thanks for any clue!
