Ruby on rails 使用简单表单的单选按钮在关联的“属于”侧具有多个直通关联

我想知道如何在我的预约表中把医生列表作为单选按钮。现在如果我使用“f.input:medicine\u id，：as=>：单选按钮”，我会得到一个“Yes/No”单选按钮。如果我改为“f.association:medicine\u id，：as=>：radio\u buttons”，那么我将得到运行时错误“association:user\u id not found”

顺便说一下，我用的是简单的表格

谢谢

我的预约表格：

<%= simple_form_for(@appointment) do |f| %>
  <div class="form-inputs">
    <%= f.hidden_field :patient_id %>
    <%= f.input :physician_id, :as => :radio_buttons %>
    <%= f.hidden_field :appointment_date, :value => DateTime.now  %>
  </div>

  <div class="form-actions">
    <%= f.button :submit, "Create Appointment" %>
  </div>
<% end %>

：单选按钮%>
DateTime.now%>

我的模型：

/app/models/medicine.rb

class Physician < ActiveRecord::Base
  has_many :appointments
  has_many :patients, :through => :appointments

  attr_accessible :physician_name
end

class医生：预约
属性可访问：医生姓名
结束

/app/models/appointment.rb

class Appointment < ActiveRecord::Base
  belongs_to :physician
  belongs_to :patient

  attr_accessible :physician_id, :patient_id, :appointment_date, :state
end

班级预约

/app/models/patient.rb

class Patient < ActiveRecord::Base
  has_many :appointments
  has_many :physicians, :through => :appointments

  attr_accessible :patient_name
end

class Patient：预约
属性可访问：患者名称
结束

我的控制器：

/app/controllers/appointment\u controller.rb

class AppointmentsController < ApplicationController
  def new
    @appointment = Appointment.new
    @appointment.patient_id = params[:patient_id]
  end

  def create
    @appointment = Appointment.new(params[:appointment])

    if @appointment.save
      flash[:notice] = "New appointment record created"
      redirect_to dashboards_path
    else
      render 'new'
    end
  end
end

类指定控制器

您应该将关联名称传递给

关联

方法

f.association :physician, :as => :radio_buttons

尝试

f.关联：医师，：as=>：单选按钮
