Rails应用程序不适用于heroku

Question

I'm trying to use sendgrid to send confirmation emails to users after they sign up. Everything was working before I tried configuring send grid, but now as soon as a user tries to sign up, I get the heroku error message to check the logs. I don't know what to make of the logs because every single thing is just a fatal error:

 2016-09-24T02:33:00.151277+00:00 app[web.1]: F, [2016-09-24T02:33:00.151247 #3] FATAL -- : [e27b857c-d6d7-4e1d-a859-0abf408efa52]   vendor/bundle/ruby/2.2.0/gems/actionmailer- 5.0.0.1/lib/action_mailer/message_delivery.rb:96:in `block in deliver_now'

EDIT: Going back in the logs I found these

These are just the first few. I feel like they're not telling me enough to figure out how to fix the problem.

The link to the repository if that helps at all: https://github.com/hbrodsk1/facebook

Any guidance would be awesome because I'm truly stuck at this point.

Answer 1

Have you set your SENDGRID USERNAME and PASSWORD in the rails console through "heroku config:set"? And also including your SENDGRID USERNAME and PASSWORD in your .bashrc file (if you are on c9). Maybe you might like to share what set up procedures you have done for sendgrid?

Answer 2

您必须在heroku配置或rails应用程序的production.rb文件中设置sendgrid用户名和密码。

Answer 3

It looks like you haven't configured the production environment to use Sendgrid for your mailer. Adding this to your production.rb in the config/environments folder should be the first step. That is as long as you define SENDGRID_USERNAME and SENDGRID_PASSWORD somewhere in the code.

config.action_mailer.smtp_settings = { :address => 'smtp.sendgrid.net', :port => '587', :authentication => :plain, :user_name => ENV['SENDGRID_USERNAME'], :password => ENV['SENDGRID_PASSWORD'], :domain => 'heroku.com', :enable_starttls_auto => true }

This error is coming up because Devise is attempting to handle a mailer event but can't find the instructions on how to process the mailer for the production environment. You've defined this in the local/development environment already so that's why it works locally. This should at least point you in the correct direction.

Check this out as a resource too: https://sendgrid.com/docs/Integrate/Frameworks/rubyonrails.html#-Configure-ActionMailer-to-Use-SendGrid

Answer 4

It turns out that I had to reset my send grid environment username from my console and it worked. Thank you for all of your responses and help though.
