Passing Variable into Rails Mailer

Question

Hey there Stack Users,

I have been frustrated with this problem for about two hours now and don't know what I am doing wrong. I am calling a method send_intro_emailon an update action for a User. The send_intro_email method calls a NotificationMailer method named intro_email(user).

The problem I am having is the data for user is being passed all the way until the point of where it is used inside .erb email. I tested it and it actually is being passed but don't know why I can't use it inside the email itself.

Files:

notificaion_mailer.rb

def intro_email(user)
   puts user # works
   mail(to: "email", from: "email2", subject: "THIS IS A TEST")
end

User.rb

def send_intro_email 
  NotificationMailer.intro_email(self).deliver
end

intro_email.erb

The users name is <%= user.name %>.

I can show an error message later when I get on my other PC if needed. Thank you so much for any help.

Well, you are using local variable user, which has scope only to the method you have defined. You have to use instance variable @user as an example. So changes are to be done like :

def intro_email(user)
   @user = user
   mail(to: "email", from: "email2", subject: "THIS IS A TEST")
end

Then inside the view use @user. Like

The users name is <%= @user.name %>.
