邮件预览无法正常工作

Question

My mailer is named send_invoice_mailer.rb (it works in dev and in prod).

I want to be able to preview the send_checkout_invoice function using the mailer preview.

routes.rb :

scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
  #app routes
end

/spec/mailers/previews/send_invoice_preview.rb AND /test/mailers/previews/send_invoice_preview.rb (not sure wich one is the correct one so I symlinked the file)

class SendInvoicePreview < ActionMailer::Preview

  def send_checkout_invoice
    #initializing foo
    SendInvoice.send_checkout_invoice(foo)
  end
end

When I go to : /rails/mailers/send_invoice/send_checkout_invoice I am redirected to /fr/rails/mailers/send_invoice/send_checkout_invoice with this error:

No route matches [GET] "/fr/rails/mailers/send_invoice/send_checkout_invoice"

EDIT : rails is 4.2 and this is done in dev with passenger. App has been upgraded from previous rails versions multiple times.

EDIT 2 : /rails/mailers also does not work. Is it because of the locale scope?

Answer 1

The location of the mailer previews directory can be configured using the preview_path option which has a default of test/mailers/previews:

Try updating your configuration path for action mailer preview as below:

config.action_mailer.preview_path = "#{Rails.root}/lib/mailer_previews"

which fails if test directory was not in production.

Answer 2

I had a few routes at the end of routes.rb that caught all requests. It works perfectly now.
