ruby-on-rails – ActionMailer link_to显示操作失败并显示“缺

mailer.rb

class Mailer < ActionMailer::Base
  default from: "foo@bar.com"

  def catalog_download_request(email,catalog)
    @catalog = catalog

    mail({
         to: email
    })
  end

end

的routes.rb

Rails.application.routes.draw do

  scope "(:locale)" do
    resources :catalogs,:path => I18n.t("routes.catalogs"),only: [:index,:show]
  end

end

development.rb：

config.action_mailer.default_url_options = { host: "http://localhost:3000" }
config.action_mailer.asset_host = "http://localhost:3000"

config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {
  address: "localhost",port: 1025
}

config.action_mailer.raise_delivery_errors = false

我打电话给邮件的模特：

class CatalogDownloadRequest < ActiveRecord::Base
  belongs_to :catalog

  after_create :send_mail

  private

  def send_mail
    Mailer.catalog_download_request(email,catalog).deliver
  end

end

这就是我在我看来尝试的内容：

<%= link_to @catalog %>

错误：

ActionView::Template::Error: No route matches {:action=>”show”,:controller=>”catalogs”,:format=>nil,:id=>nil,:locale=>#} missing required keys: [:id]

另一个尝试：

<%= link_to catalog_url(@catalog) %>

错误：

ActionView::Template::Error: No route matches {:action=>”index”}

我怀疑这种情况正在发生,因为我在路线上的语言环境范围.

如果我使用<％= link_to catalog_url(@catalog)％>在另一种观点中,它有效.

解决：

<%= link_to catalog_url(:id => @catalog.id),catalog_url(:id => @catalog.id) %>
