Ruby on rails 缺少rails mailer开发环境的模板

我正在学习Ryan Bates关于密码重置的教程，但在完成它时遇到了困难

当我尝试运行密码重置时，出现错误--

缺少模板用户\u mailer/密码\u用“mailer”重置。在以下位置搜索：“\u用户邮箱”

*我不知道为什么会这样说，我在app/views/user\u mailer/password\u reset.text.erb下有一个password\u reset.text.erb文件*

这是

密码\u重置控制器

class PasswordResetsController < ApplicationController
  def new
  end

  def create
    user = User.find_by_email(params[:email])
    user.send_password_reset if user
    redirect_to root_url, :notice => "Email sent with password reset instructions"
  end
end

类密码重置控制器“发送带有密码重置说明的电子邮件”

<%= form_tag password_resets_path, :method => :post do %>
  <div class="field">
    <%= label_tag :email %>
    <%= text_field_tag :email, params[:email] %>
  </div>
  <div class="actions"><%= submit_tag "Reset Password", :class => "button" %></div>
<% end %>

class UserMailer < ActionMailer::Base
  default from: "from@example.com"

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.user_mailer.password_rest.subject
  #
def password_reset(user)
  @user = user
  mail :to => user.email, :subject => "Password Reset"
end

end

Click the link below to reset your password.

<%= edit_password_reset_url(@user.password_reset_token) %>

If you did not request to change your password, ignore this email and your password will stay the same.

password\u reset.text.erb将其名称更改为password\u reset.html.erb

Huh，在删除.html和.erb后，它使事情正常运行：S.不确定为什么更新：嗯，奇怪，现在.html.erb和.text.erb都正常工作了：S.html意味着一个文件有各自的html代码，.erb是嵌入其中的ruby代码。如果有.text，则表示这是一个文本文件。
