启动前邮件程序不起作用

Question

I am running Harry's prelaunchr ( https://github.com/harrystech/prelaunchr ) on Heroku and the welcome email that is supposed to send out when a new user signs up on the site is not sending out. The rails app is using Delayed::Job and when I run

heroku rake jobs:work

I get the following output:

 Rendered user_mailer/signup_email.html.erb (1.2ms)
[Worker(host:46d2c895-5e66-464b-8594-510461de915c pid:3)] Class#signup_email failed with ActionView::Template::Error: undefined method `encoding' for {:host=>"windreturns.com"}:Hash - 9 failed attempts

^Note: host=>"windreturns.com" is my domain, but it is not where the site is currently located (it's a genericname.herokuapp.com domain)

Any idea why the jobs are failing? How do I get the emails to send?

Answer 1

I'm not sure why, but it seems like the file app/views/user_mailer/signup_email.html.erb has several issues, dating back to the initial commit that had a syntax error in it. The current version is using asset links like this:

<%= Rails.application.config.action_mailer.default_url_options %>/assets/logo.jpg

The first problem with this is that default_url_options is not a string, it's a hash. The second problem is that the email assets are in /assets/email . I got the email working by changing the above to:

<%= Rails.application.config.action_mailer.default_url_options[:host] %>/assets/email/logo.jpg

You have to do this in nine places, then it should work.

Also set something like DEFAULT_MAILER_HOST="http://localhost:5000" in your .env file.
