Can't make a new line in slim template

My code is the below.

mails_preview.rb

summaries = ["test\ntest\ntest\ntest", "test\ntest\ntest\ntest"]
ClientsMailer.test(summaries)

clients_mailer.rb

class ClientsMailer < ApplicationMailer
  def test(summaries)
    @summaries = summaries

    mail(
      to: "test@test.com,
      subject: "test",
    )
  end
end

test.slim

= @summaries.map { |summary| summary }.join("\n")

Output is here

test test test test test test test test

\n doesn't work for making a new line.
I can't understand why.
Do you have any ideas?

Solution

  • I lacked .html_safe.
    fixed code is the below.

    test.slim

= @summaries.map { |summary| summary }.join("\n").html_safe
