ruby-on-rails - 通过关联在 has_many 上使用 simple_form 的单选按钮，特别是在关联的belongs_to 一侧

Question

我想弄清楚如何在我的预约表格中将医生列表作为radio_buttons。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”，那么我会收到 RuntimeError “Association :user_id not found”。

顺便说一下，我为此使用了 simple_form。

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 %>

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 Controller :

/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

您应该将关联名称传递给 association方法

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