Missing template layouts/mailer with {:locale=>[:en], :formats=>[:html],

I'm following michael harlt rails tutorial but i get this error

Missing template layouts/mailer with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :coffee, :jbuilder]}. Searched in: * "/home/ubuntu/workspace/app/views"

when previewing account activation

This is my user_mailer.rb

class UserMailer < ApplicationMailer

  def account_activation(user)
    @user = user
    mail to: user.email,  subject: "Account activation"
  end

  def password_reset
    @greeting = "Hi"

    mail to: "[email protected]"
  end
end

and the error highlights the line that says

mail to: user.email,  subject: "Account activation"

I tried adding layout 'mailer' in user_mailer.rb but it doesn't work.

EDIT: Here is the screenshot of the error

The screenshot of my folders

You need to add the actual erb.html (or any other variant you might have) – Laocoon 15/7, 2016 at 14:59

If you don't already, you will need a folder within views called user_mailer and within that you will need a file for each of those methods (account_activation.html.erb & password_reset.html.erb). This is where the template of your email will be.

I have them, all html.erb files in views . – Schlimazel 15/7, 2016 at 15:40

Do you have a github link for this project? or a screenshot of your mailers folder and views where you've placed these files? – Sclerous 15/7, 2016 at 15:54

I'm using bit bucket but i can screenshot it. – Schlimazel 15/7, 2016 at 15:57

Yes please - would help if you could screenshot it. I just want to see the layout of the folders within view and your files in mailer folder. – Sclerous 15/7, 2016 at 15:58

Is the name account_activation or account_activations? of the file which is highlighted? – Sclerous 15/7, 2016 at 16:8

account_activation – Schlimazel 15/7, 2016 at 16:15

i found out that the layout 'mailer' should be 'layout mailer'. Thanks for the help. – Schlimazel 15/7, 2016 at 17:3

@wemode, that is equivalent to commenting out the line. In ruby, any literal value, like "string" or 42 does nothing. – Giffin 9/10, 2016 at 3:57

I had the same problem, and it seemed to work for me if I commented out the layout 'mailer' line in application_mailer

eg

class ApplicationMailer < ActionMailer::Base
  default from: '[email protected]'
  # layout 'mailer'
end

Any idea why the rails generate command did not produce the layout files for us and it did for Michael Hartl? – Equivalent 12/2, 2017 at 14:10

The issue is the next:

to generate this mailer you use this command

$rails generate mailer UserMailer account_activation password_reset

sending back

create  app/mailers/user_mailer.rb
create  app/mailers/application_mailer.rb
invoke  erb
create    app/views/user_mailer
create    app/views/layouts/mailer.text.erb
create    app/views/layouts/mailer.html.erb
invoke  test_unit
create    test/mailers/user_mailer_test.rb
create    test/mailers/previews/user_mailer_preview.rb

by a strange way app/views/layouts/mailer.html.erb file is not generated so when you call

layout 'mailer'

the rails core send you this error

"Missing template layouts/mailer"

you can resolve this by 2 ways.

First: comment out or delete layout 'mailer'.
Second: Creating the file.

Another ways like 'layout mailer' are bad practices cause this syntax have no sense for Rails.

If you create the file, use this code to fill it

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <style>
      /* Email styles need to be inline */
    </style>
  </head>

  <body>
    <%= yield %>
  </body>
</html>

Creating a blank file raised an exception. Creating one with just a HTML comment caused blank HTML view output (text worked fine). What content did you have in the file? – Giffin 9/10, 2016 at 8:19

Thanks. Try using backticks - ` to mark text as code – Giffin 14/10, 2016 at 6:12

I had this same issue and what resolved it is ensuring I had two files in .../app/views/layouts/: mailer.html.erb and mailer.text.erb.

mailer.html.erb:

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <style>
      /* Email styles need to be inline */
    </style>
  </head>

  <body>
    <%= yield %>
  </body>
</html>

mailer.text.erb:

<%= yield %>

What was the content of those files? – Giffin 9/10, 2016 at 3:43

@TomHale, I've edited my response to include to contents of both files. – Mainstream 16/10, 2016 at 12:50

Excellent, this is the solution I went with. I believe it is the only one which works generically in the text-only case - thanks! – Giffin 17/10, 2016 at 7:48

Make sure you have the file app/mailers/application_mailer.rb From Hartl's tutorial:

class ApplicationMailer < ActionMailer::Base
 default from: "[email protected]"
 layout 'mailer'
end

I do have that file with all user_mailers templates in views – Schlimazel 15/7, 2016 at 15:39

Your UserMailer class, is still inheriting from the ApplicationMailer which defines the base layout directory as layout 'mailer'. For your current code and folder structure to work, you could make the following changes.

From this

UserMailer < ApplicationMailer

To this

UserMailer < ActionMailer::Base
