Instance variables not working in templates

[RemiKalbe]

I created a text and HTML template, I have a couple of instance variables but when the email is sent the variables aren't replaced by their value they stay like that #{@name_of_the_variable}.

My class is like that:

class ConfirmationEmail < BaseEmail
    @title : String
    @sub_title : String
    @body : String

    def initialize(@email_address : String, @language : String, @confirmation_code : String)
      @title = translate("email_confirmation_title", @language, Nil)
      @sub_title = translate("email_confirmation_sub_title", @language, Nil)
      @body = translate("email_confirmation_body", @language, Nil)
    end

    to @email_address
    subject translate("email_confirmation_subject", @language, Nil)
    reply_to "[email protected]"
    templates text, html
  end

Here is my text template, couldn't be simpler:

#{@title}
#{@sub_title}

#{@body}


#{@confirmation_code}

I won't show my HTML template it's way too big. And I don't think it matters as the issue also involve the text template.

So when the email is sent, I receive the email like that:

#{@title}
#{@sub_title}

#{@body}


#{@confirmation_code}

Not, with the actual values.

Am I doing something wrong here?

I figured it out!

I replaced

#{@name_of_the_variable}

by

<%= @name_of_the_variable -%>

( from https://crystal-lang.org/api/0.21.1/ECR.html )

And now it works!
