Question

目前我有两种型号。

class Booking
  include Mongoid::Document
  include Mongoid::Timestamps
  field :capacity, type: Integer
  field :date, type:Date

  embeds_many :appointments
  attr_accessible :capacity, :date, :appointments_attributes
  accepts_nested_attributes_for :appointments
end

class Appointment
  include Mongoid::Document
  field :name, type: String
  field :mobile, type: String

  embedded_in :booking
end

如何为预约中嵌入的约会创建表单？理想情况下，我希望能够通过指定预订日期将预约添加到预订中。

我可以在控制台中执行此操作，但无法找到为此创建表单的方法。

我试过这个，这不起作用

<%= form_for(@booking) do |f| %>
  <div class="field">
    <%= f.label :capacity %><br />
    <%= f.text_field :capacity %>
  </div>
  <div class="field">
    <%= f.label :date %><br />
    <%= f.text_field :date %>
  </div>

  <h1>  form for appointment </h1>
        <%= f.fields_for :appointments do |builder| %>
          <div class="field">
            <%= builder.label :name %><br />
            <%= builder.text_field :name %>
          </div>
          <div class="field">
            <%= builder.label :mobile %><br />
            <%= builder.text_field :mobile %>
          </div>

        <% end %>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

预约控制器中的

  def create
    @booking = Booking.new(params[:booking])
    @appointment = @booking.appointments.build(params[:appointments])

    respond_to do |format|
      if @booking.save
        format.html { redirect_to @booking, notice: 'Booking was successfully created.' }
        format.json { render json: @booking, status: :created, location: @booking }
      else
        format.html { render action: "new" }
        format.json { render json: @booking.errors, status: :unprocessable_entity }
      end
    end
  end

控制台命令执行表单所要执行的操作：

book = Booking.create(capacity: 10, date: Date.today)
book.appointments.create(name: "Josh", mobile: "19923")
book.appointments.create(name: "Bosh", mobile: "123344")
book.appointments
 => [#<Appointment _id: 51a083c332213f2cc9000002, _type: nil, name: "Josh", mobile: "19923">, #<Appointment _id: 51a0840632213f2cc9000003, _type: nil, name: "Bosh", mobile: "123344">]

所以我解决了这个问题。我只是使用它自己的控制器和表格来创建应用程序文档，而不是使用嵌套表单。我在应用程序模型中添加了一个日期字段，在控制器内部，我查询了具有该日期的预订文档，并使用该预订创建了应用程序。

这是代码：

  def create
    date = params[:appointment]['date']
    booking = Booking.find_or_create_by(date: date)
    @appointment = booking.appointments.new(params[:appointment])


    respond_to do |format|
      if @appointment.save
        format.html { redirect_to booking, notice: 'Appointment was successfully created.' }
        format.json { render json: @appointment, status: :created, location: @appointment }
      else
        format.html { render action: "new" }
        format.json { render json: @appointment.errors, status: :unprocessable_entity }
      end
    end
  end
