其他控制器

Question

我想从其他控制器创建，编辑和删除db实体，而不是由scaffold生成。我希望在没有重定向的情况下进行验证，创建和删除。我不想使用生成的控制器，因为我想从一个控制器创建至少两种类型的实体。

现在我创建了没有重定向但我没有关于实体创建的通知。

此控制器应支持crud操作：

class SmartHomeController < ApplicationController

  layout 'smart_home'

  def index
    @name = 'Home';
  end

  def settings
    @name = 'Settings';

    @place = Place.new;

    @all_places = Place.all;

    respond_to do |format|
      if @place.save
        format.html { redirect_to @place, :notice => 'A was successfully created.' }
      else
        # render new with validation errors
        format.html { render :action => "settings" }
      end

    end
  end
end

脚手架生成的控制器：

class PlacesController < ApplicationController
  before_action :set_place, only: [:show, :edit, :update, :destroy]

  # GET /places
  # GET /places.json
  def index
    @places = Place.all
  end

  # GET /places/1
  # GET /places/1.json
  def show
  end

  # GET /places/new
  def new
    @place = Place.new
  end

  # GET /places/1/edit
  def edit
  end

  # POST /places
  # POST /places.json
  def create
    @place = Place.new(place_params)

    respond_to do |format|
      if @place.save
        format.html { redirect_to smart_home_settings_path, notice: 'Place was successfully created.' }
        format.json { render :show, status: :created, location: @place }
      else
        format.html { render :new }
        format.json { render json: @place.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /places/1
  # PATCH/PUT /places/1.json
  def update
    respond_to do |format|
      if @place.update(place_params)
        format.html { redirect_to @place, notice: 'Place was successfully updated.' }
        format.json { render :show, status: :ok, location: @place }
      else
        format.html { render :edit }
        format.json { render json: @place.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /places/1
  # DELETE /places/1.json
  def destroy
    @place.destroy
    respond_to do |format|
      format.html { redirect_to places_url, notice: 'Place was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

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

    # Never trust parameters from the scary internet, only allow the white list through.
    def place_params
      params.require(:place).permit(:name, :hw)
    end
end

你能指导我如何实现这个目标吗？

编辑。新代码。

删除有效，但没有确认：

页：

<%= link_to 'Destroy', delete_place_path(id: place.id), data: {:confirm => 'Are you sure?'}, :method => :delete %>

控制器：

def delete_place
    place = Place.find(params[:id])
    place.destroy

    respond_to do |format|
      format.html { redirect_to smart_home_settings_path, notice: 'Place was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

路线：

  get 'delete_place/:id' => 'smart_home#delete_place', as: :delete_place
