Can't get Swoosh to use the template I'm specifying.

Questions / Help

Hi,

I´m trying to send email using Phoenix.Swosh, but I get this error message that I don´t really understand.

This is how I send the mail:

      MyCompany.UserEmail.mail_requesting_signature(%{
        contract: contract,
        current_user: sender
      })
      |> MyCompany.Mailer.deliver()


defmodule MyCompany.UserEmail do
  use Phoenix.Swoosh,
    template_root: "lib/MyCompany_web/templates/emails/",
    template_path: "requesting_signature"


  def mail_requesting_signature(%{
        contract: contract,
        current_user: current_user
      }) do
    sender_email = extract_string(current_user.email)
    recipient_email = contract.client.email
    recipient_name = "John Doe"

    new()
    |> to({recipient_email, recipient_name})
    |> from({"MyCompany", "no-reply@MyCompany.no"})
    |> subject("#{sender_email} has invited you to sign a contract")
    |> render_body(
      "requesting_signature.html.heex",
      %{
        username: user.email,
        title: contract.title,
        content: contract.content,
      }
    )
  end
end

 ** (Phoenix.Template.UndefinedError) Could not render "mail_template.html.heex" for MyCompany.UserEmail, please define a matching clause for render/2 or define a template at "lib/MyCompany_web/templates/emails/mail_template/*". The following templates were compiled:

 Assigned keys: [:title, :username, :email, :content,]

The template:
lib/quantik_web/templates/emails/requesting_signature/requesting_signature.html.heex

<div>
  <h1>Document to be signed</h1>
  <h1>Welcome to MyCompany, <%= @username %>!</h1>
  <pre> Please read the document below: </pre>
  <h2><%= @title %></h2>
  <pre> <%= @content %> </pre>
</div>

I think you need to drop the .heex part of the template name you’re passing into Phoenix.Swoosh.render_body/3.

Edit: but I think your template is also not found where phoenix_swoosh expects it, because it’s not being listed as one of the possible templates in the error. It is searching here: lib/MyCompany_web/templates/emails/mail_template/*, where it can find mail_template.html.heex (I guess), but not your other template. Make sure they are next to each other.

Yes, that was it! I removed the .heex part of the template name, and it worked.
Thanks, @linusdm :blush:
