Rails 3 -Render PDF from view and attach to email

Question

I have been using Wicked_pdf to render a view as a PDF and actionmailer to send emails, but I can\'t get them to work together. I want to attach a PDF version of a certain v

Answer 1

2 good ways to do this the way you want:

1: Create the pdf in the controller, then send that to the email as a param.

# controller
def sendemail
  @user = User.find(params[:id])
  pdf = render_to_string :pdf => 'MyPDF'
  Sendpdf.send_report(@user, pdf).deliver
  redirect_to user_path(@user)
  flash[:notice] = 'Email has been sent!'
end

# mailer
def send_report(user, pdf)
  @user = user
  attachments['MyPDF.pdf'] = pdf
  mail(:to => user.email, :subject => "awesome pdf, check it")
end

2: Create the pdf in the mailer directly (a little more involved, but can be called from a model)

def send_report(user)
  @user = user
  mail(:to => user.email, :subject => "awesome pdf, check it") do |format|
    format.text # renders send_report.text.erb for body of email
    format.pdf do
      attachments['MyPDF.pdf'] = WickedPdf.new.pdf_from_string(
        render_to_string(:pdf => 'MyPDF',:template => 'reports/show.pdf.erb')
      )
    end
  end
end
