如何在Ruby on Rails中使用带有邮件程序的实例变量？

Question

I created an instance variable (@user) in the model of a mailer and want to access it in the view? But it's giving me an an error (@user = nil). What's the best way to pass a variable to view (the email body)?

Thanks, Chirag

Answer 1

If you want to access an instance variable in your mailer template then in your mailer model add

@body[:user] = user_object

The above would create an instance variable @user that can be accessed in your view. You should be able to access user object in your mailer view by doing

@user

The docs here have examples of alternative ways if you are using multiple formats (text/html).

Answer 2

I Rails 3 the process is similar:

@user = user_object

The above would create an instance variable @user that can be accessed in your view. You should be able to access user object in your mailer view by doing

@user

Note that you need to set this variable before the

mail(:from => "info@domain.info", :to => recipient, :subject => "Subject")

Answer 3

要将变量传递给视图/电子邮件正文，您可以通过正文方法发送它们:-) 因此，例如 ， body :account => recipient将导致实例变量@account ，其中可以访问recipient的值视图。
