单选按钮上使用simple_form has_many通过关联belongs_to侧特别是关联

我想弄清楚我怎么能有我的预约形式作为radio_buttons的医生名单。现在，如果我使用“f.input：physician_id，：as =>：radio_buttons”，我会得到一个“是/否”单选按钮。如果我更改为“f.association：physician_id，：as =>：radio_buttons”，那么我得到RuntimeError“Association：user_id not found”。单选按钮上使用simple_form has_many通过关联belongs_to侧特别是关联

顺便说一下，我使用simple_form这个。

谢谢。

我的约会形式：

<%= 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 %>

我的模型：

/app/models/physician.rb

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

    attr_accessible :physician_name 
end

/app/models/appointment.rb

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

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

/app/models/patient.rb

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

    attr_accessible :patient_name 
end

我的控制器：

/app/controllers/appointment_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

尝试'f.association：医师，：as =>：radio_buttons' – 2012-08-09 11:44:44

这是有效的。谢谢：-） – Azren 2012-08-09 13:39:22

你应该通过协会的名字到association方法

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