actionmailer

问题 I'm trying to use actionmailer to notify me when a new comment has been posted but I keep getting the error: uninitialized constant CommentsController::CommentMailer The comment is added to my database and can be viewed. I am also using devise and it's email functions are working fine. My comment mailer: class CommentMailer < ActionMailer::Base def newcomment(comment) mail(:to => "admin@example.com", :subject => "New Comment") end end and my controller section: def create @comment = Comment

问题 Setup: Ruby 1.9.2 Rails 3.2.2 I'm having some trouble with the encoding of my emails. Note: I'm not that familiar with encoding and stuff like that. When sending an email with ActionMailer, something weird is going on with the html in the email. All equal(=) signs are getting changed to =3D . Example: <table border=3D"0" cellpadding=3D"0" cellspacing=3D"0" width=3D"=440"> <tbody> <tr> <td height=3D"10"> </td> </tr> </tbody> </table> Special characters looks like this: ä -> ä . It looks great

问题 How can I serialise the mailer so that it can be stored for further use? The serialised data should be disconnected and self sufficient to be delivered on separate machine that should deliver that message (not knowing about database or anything else). 回答1: Suppose you usually send emails with this: MyMailer.some_email(...).deliver Instead delivering it, you can convert it to a string and transfer the string to another server: raw_mail = MyMailer.some_email(...).to_s On another server, send

问题 I'm using the free sendgrid plan to send email from my rails app hosted on heroku. I set it up using a combination of these instructions and this tutorial It's all working, but on gmail the it the sender comes through as 'myemail@myapp.com via sendgrid.me' Is there any way to get rid of this? I've had a look at this forum but it's not very clear on whether it's possible. If I can't remove it, can anyone recommend an alternative, free, service? 回答1: I know its an old question. But things are

问题 Using Rails 3 I want to use an X.509 certificate to sign parts of emails. There is a currently existing answer for Rails 2 at How do I send signed emails from ActionMailer? but it doesn't work on Rails 3. Is it possible to sign emails via ActionMailer in Rails 3? If that is not possible, is it possible to sign emails via sendmail after creating by ActionMailer? 回答1: perhaps it's not the best answer, however here's what I'd do: try to install that plugin (even if it's for rails 2.0.x) tests

问题 I have tried all kinds of configurations but still I can't send an email in my development environment from rails. I installed mailutils to try this from the command line and it worked, I received the email (in spam of course): echo test | mail -s Subject user@example.com Here's my config: # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = true # still no logs about emails config.action_mailer.delivery_method = :smtp config.action_mailer.perform_deliveries =

问题 I got an rails 4 application with following mailer configuration: config.action_mailer.delivery_method = :smtp config.action_mailer.default_url_options = { host: 'myhost.com' } config.action_mailer.perform_deliveries = true config.action_mailer.smtp_settings = { :enable_starttls_auto => true, :address => 'smtp.myhost.com', :port => 587, :domain => 'myhost.com', :authentication => :login, :enable_starttls_auto => false, :tls => false, :openssl_verify_mode => 'none', :ssl => false, :user_name =

问题 When sending mail through actionmailer, the actionmailer gets a response from the SMTP server, when its ok, or when its wrong. Is there a way to retrieve this response after sending a mail? Also when no errors are thrown by the SMTP server? Our qmail mail server throws a handler id which we want to use for tracing e-mails. As an example, the server response is this : 250 ok 1308235825 qp 17832 回答1: Set return_response: true in the smtp settings and call message.deliver! instead of deliver .

问题 I'm using Paperclip and S3 for file upload and storage in a Rails 3 app. The uploading of the files is working well, but when trying to attach an uploaded file to an email message with actionmailer, I am running into issues. After a lot of troubleshooting, hopefully someone can offer a hint. From a high level, it seems like I may need to download the file first, with some kind of download method before attaching, which is suggested here but I do not quite follow on how to implement -
