Question

我的Reminders模型（date和mail_date）中有两列，其列类型为datetime，您可以在schema.rb中看到：

create_table "reminders", force: :cascade do |t|
    t.string   "name"
    t.datetime "date"
    t.boolean  "reminder",      default: false
    t.string   "repeating"
    t.boolean  "approved"
    t.boolean  "gift",          default: false
    t.boolean  "gift_help",     default: false
    t.string   "occasion_type", default: "Other"
    t.integer  "user_id"
    t.datetime "created_at",                      null: false
    t.datetime "updated_at",                      null: false
    t.string   "slug"
    t.datetime "mail_date"
  end

但是，在我的console中，它们仅显示为日期：

[33] pry(main)> Reminder.where(name: "Mentor Call")
  Reminder Load (0.4ms)  SELECT "reminders".* FROM "reminders" WHERE "reminders"."name" = ?  [["name", "Mentor Call"]]
=> [#<Reminder:0x007fe32b13f090
  id: 8,
  name: "Mentor Call",
  date: Thu, 27 Oct 2016,
  reminder: true,
  repeating: "Weekly",
  approved: nil,
  gift: false,
  gift_help: false,
  occasion_type: "Other",
  user_id: 1,
  created_at: Thu, 13 Oct 2016 01:59:57 UTC +00:00,
  updated_at: Fri, 21 Oct 2016 23:47:16 UTC +00:00,
  slug: "mentor-call",
  mail_date: Thu, 27 Oct 2016>]

我知道datetime数据正在保存，因为它显示在我的视图页面上，这里......

October 27, 2016 07:00  Mentor Call     ... 2016-10-27 07:00:00 UTC

...是从这个erb生成的：

<% @reminders.each do |o| %>
    <tr>
      <td>
        <%= o.date.try(:to_formatted_s, :long) %>
      </td>
      <td>
        <%= link_to reminder_path(o), style: "color: black" do %>
          <strong><%= o.name %></strong>
        <% end %>
        ...
      <td>
        <% if o.reminder %>
          <%= o.mail_date.try(:to_formatted_s, "%m/%d/%Y") %>
        <% else %>
          None, you're on your own.
        <% end %>
      </td>
    </tr>

我正在尝试创建mailer，mail_date发送datetime，但由于此date vs {{1}}问题，我遇到了麻烦（我认为）。谁能让我理顺？

我怀疑date列的名称与Rails＆＃39;或者Ruby的reserved words。将date列的名称更改为其他内容，例如remind_at，这应该可以解决问题：

create_table "reminders", force: :cascade do |t|
  t.string   "name"
  t.datetime "remind_at"
  t.boolean  "reminder",      default: false
  # ...
end

Rails控制台仅显示日期时间列的日期
