Question

如何将以下form_for - collection_select翻译为simple_form？

<%= collection_select(:service, :service_menu_id, @service_menus, :id, :name, prompt: true) %>

要...

<%= f.input ...

要求更新：

<div class="col-xs-4">
<%= simple_form_for @service do |f| %>
    <div class="field">

        <!--Working - selected value saves to db-->
        <%= collection_select(:service, :service_menu_id, ServiceMenu.all, :id, :name, {:prompt => true }) %>

        <!--Selected value does not save to db-->
        <%#= f.input :service_menu, :collection => @service_menus, label_method: :name, value_method: :id, :include_blank => false, prompt: "Select a main service" %>

        <%= f.simple_fields_for :styles do |task| %>
            <%= render 'style_fields', :f => task %>
        <% end %>
    </div>

    <div class="links">
        <%= link_to_add_association 'Add New Style', f, :styles, class: 'btn btn-success' %>
    </div><br>

    <div class="actions">
        <%= f.submit :class => 'btn btn-primary'%>
    </div>
<% end %>

控制器

class ServicesController < ApplicationController

  before_action :set_service, only: [:show, :edit, :update, :destroy]

  def index
      @services = current_tech.services
  end

  def show
  end

  def new
    @service = current_tech.services.build
    @service_menus = ServiceMenu.all
  end

  def create
    @service = current_tech.services.build(service_params)
    respond_to do |format|
      if @service.save
        format.html { redirect_to @service, notice: 'Service was successfully created.' }
        format.json { render :show, status: :created, location: @service }
      else
        format.html { render :new }
        format.json { render json: @service.errors, status: :unprocessable_entity }

    end
  end

  def update
    respond_to do |format|

        format.html { redirect_to @service, notice: 'Service was successfully updated.' }
        format.json { render :show, status: :ok, location: @service }
      else
        format.html { render :edit }
        format.json { render json: @service.errors, status: :unprocessable_entity }

    end
  end

  def destroy
    @service.destroy
    respond_to do |format|
      format.html { redirect_to services_url, notice: 'Service was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_service
      @service = Service.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def service_params
      params.require(:service).permit(:name, :service_menu_id, styles_attributes: [:id, :tech_id, :name, :hours, :minutes, :price, :details, :_destroy])
    end
end

如果您可以将其包装为 表单对象 （即f.collection_select），那么这将有效

<%= f.input :service_menu, :collection => @service_menus, :label_method => :name, :value_method => :id, :selected => @service.service_menu_id :include_blank => true %>
