Hi everyone,
I'm having trouble accessing instance vars passed to my email template as part of an explicit multipart message, and I wonder if anyone here could help me.
The task at hand is to deliver email with only the text/html content type if the message lacks a plaintext (from a record in the db) and to send multipart email if it has both plaintext & html available.
Here's the simplified code from the mailer:
#SampleMailer.rb
def email(recipient, content) subject content.title recipients recipient.email from 'sender@example.com' headers 'return-path' => 'sender@example.com' sent_on Time.now
if context.plaintext.empty? # force HTML email if the module lacks plaintext content_type 'text/html' body :content => content, :user => recipient else # send a multi-part email part "text/plain" do |p| p.body = render_message("email_plain", :content => content, :user => recipient) p.transfer_encoding = "base64" end part "text/html" do |p| p.body = render_message("email", :content => content, :user => recipient) end end end
This works fine if content.plaintext is empty -- it properly delivers the HTML-only email. If however, content.plaintext is not empty (ie, it should send a multipart message), the template throws an error. For a template like:
# email.erb
<%= @content.title %>
The error is:
NoMethodError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.title)
Thank you for your help in looking at this. I'm much obliged for any advice you can offer.
Sincerely,
Jacob
