TypeError: can't define singleton

[hayesgm]

I'm getting the following error when trying to send a message: TypeError: can't define singleton. I'm attempting to updating from roadie 2.0 to roadie-rails, but this is a blocker. I'm using rails 4.0.8. Also, I'm using the sendgrid gem which is present in the backtrace.

Code

UserMailer.my_letter().deliver

Thanks for help getting this fixed.

That's weird. It's saying that Roadie cannot extend the Mail object for some reason. You could go with a manual Mailer for moment if you want to upgrade. I'll take a look in the meantime. Den 22 jul 2014 08:22 skrev "Geoff Hayes" notifications@github.com:

Hmm, could it be that your Mailer method isn't returning an instance of Mail, but rather a symbol, numeric, true, false, nil or something similar? Perhaps you could inject a small p mail in the line of the exception to see what it is. Den 22 jul 2014 19:10 skrev "Magnus Bergmark" magnus.bergmark@gmail.com:

@Mange Yeah, I was going to do that to see what could be causing this.

[hayesgm]

I added p email in Roadie::Rails::Automatic module:

def mail(*args, &block)
  super.tap do |email|
    p email
    email.extend InlineOnDelivery
    email.roadie_options = roadie_options.try(:dup)
  end
end

Result

:user_mailer

So the question is how that is coming up as the response.

I tried removing the sendgrid gem, as well as all other includes, default and interceptors to no avail.

That's really weird! Maybe you could trace it from Rails' source code? What does your Mailer method look like? It might be an option you are passing that causes it. If you were to remove the Automatic module and print the result of the #mail call, do you get a proper email? If so, Roadie must be the one to blame.
