Ruby on rails 行动'；破坏性'；在控制器中找不到

我想我要失去它了。我不明白为什么一个简单的销毁链接会突然失效

我得到了这个错误：

AbstractController:：ActionNotFound位于/plans/v41w74v2 找不到PlansController的操作“销毁”

计划控制员：

class PlansController < ApplicationController
before_filter :authenticate_user!

def index
  @plans = Plan.all
end
def new
  @plan = Plan.new
end
def create
  @plan = Plan.new(plan_params)
  if @plan.save
    if @plan.trips.empty?
      @possible = @plan.group.trips
      render "add_trips"
    else
      redirect_to plans_path, notice: "Plan successfully created"
    end
  else
    render "new"
  end
end
def show
  @plan = Plan.find_by_unique_identifier(params[:id])
end
def edit
  @plan = Plan.find_by_unique_identifier(params[:id])
  @group = @plan.group
  @possible = @plan.group.trips
  render "add_trips"
end
def update
  @plan = Plan.find_by_unique_identifier(params[:id])
  if @plan.update_attributes(plan_params)
    redirect_to plans_path, notice: "Plan successfully updated!"
  else
    render "edit"
  end
end
def add_trips
  @plan = Plan.find_by_unique_identifier(params[:id])
  trip.each.update_attributes(plan_id: @plan.id)
  redirect_to plans_path, notice: "Trips added to plan"    
end
def destory
  @plan = Plan.find_by_unique_identifier(params[:id])
  @plan.destroy
end

类平面控制器

平面视图：

<%= button_to "Delete", @plan, method: :delete, data: { confirm: "Are you sure you want to delete this plan?"} %>

我做错了什么？

是的。你打错了<代码>销毁
