RubyonRails按钮不能正常工作(帮助?)

Question

在我的项目中，"销毁"按钮与"显示"按钮类似。这个项目是用脚手架做的。我不知道怎么了，你能帮我吗？

这是我的控制器文件

class BloknotsController < ApplicationController
  before_action :set_bloknot, only: [:show, :edit, :update, :destroy]
  # GET /bloknots
  # GET /bloknots.json
  def index
    @bloknots = Bloknot.all
  end
  # GET /bloknots/1
  # GET /bloknots/1.json
  def show
  end
  # GET /bloknots/new
  def new
    @bloknot = Bloknot.new
  end
  # GET /bloknots/1/edit
  def edit
  end
  # POST /bloknots
  # POST /bloknots.json
  def create
    @bloknot = Bloknot.new(bloknot_params)
    respond_to do |format|
      if @bloknot.save
        format.html { redirect_to @bloknot, notice: 'Bloknot was successfully created.' }
        format.json { render :show, status: :created, location: @bloknot }
      else
        format.html { render :new }
        format.json { render json: @bloknot.errors, status: :unprocessable_entity }
      end
    end
  end
  # PATCH/PUT /bloknots/1
  # PATCH/PUT /bloknots/1.json
  def update
    respond_to do |format|
      if @bloknot.update(bloknot_params)
        format.html { redirect_to @bloknot, notice: 'Bloknot was successfully updated.' }
        format.json { render :show, status: :ok, location: @bloknot }
      else
        format.html { render :edit }
        format.json { render json: @bloknot.errors, status: :unprocessable_entity }
      end
    end
  end
  # DELETE /bloknots/1
  # DELETE /bloknots/1.json
  def destroy
    @bloknot.destroy
    respond_to do |format|
      format.html { redirect_to bloknots_url, notice: 'Bloknot was successfully destroyed.' }
      format.json { head :no_content }
    end
  end
  private
    # Use callbacks to share common setup or constraints between actions.
    def set_bloknot
      @bloknot = Bloknot.find(params[:id])
    end
    # Never trust parameters from the scary internet, only allow the white list through.
    def bloknot_params
      params.require(:bloknot).permit(:NameOfBkoknot)
    end
end

Answer 1

确保您已设置方法：：删除按钮链接

<%= link_to "Delete", post, data: { confirm: 'Are you sure?' }, method: :delete, :class => "button" %>

Answer 2

如果您在控制台中执行rake路由，您将看到show和destroy的url完全相同，只是动词部分不同 如果是获取请求，则需要您显示操作，如果使用删除动词，则需要销毁操作，因此这可能是由两件事引起的：

a。正如@wally所指出的，请确保您在链接中使用删除方法：

 = link_to "Delete", post, data: { confirm: 'Are you sure?' }, method: :delete, class: "button"

bDelete方法需要应用程序中的jquery_ujs。Rails默认附带jquery_ujs，但请确保您的应用程序中有它
