我正在使用设计,并在我的Ruby on Rails网络应用程序中拥有一个模型。用户拥有多件作品。现在,在我的棋子控制器中,我有一个名为correct_user的方法,它只允许拥有这些碎片的用户编辑和销毁它们。我想在这个方法中添加一行,它允许设计用户id为1的用户能够编辑和销毁其他人的部分(如果current_user.id == 1,则允许编辑/销毁操作)。我尝试过几种组合,但我一直都会遇到错误。
这是我的棋子控制器:( correct_user方法即将结束)
class PiecesController < ApplicationController
before_action :set_piece, only: [:show, :edit, :update, :destroy]
before_action :correct_user, only: [:edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]
respond_to :html
def index
@pieces = Piece.all
respond_with(@pieces)
end
def show
respond_with(@piece)
end
def new
@piece = current_user.pieces.build
respond_with(@piece)
end
def edit
end
def create
@piece = current_user.pieces.build(piece_params)
flash[:notice] = 'Piece was successfully created.' if @piece.save
respond_with(@piece)
end
def update
flash[:notice] = 'Piece was successfully updated.' if @piece.update(piece_params)
respond_with(@piece)
end
def destroy
flash[:notice] = 'Piece was successfully deleted.' if @piece.destroy
respond_with(@piece)
end
private
def set_piece
@piece = Piece.find(params[:id])
end
def correct_user
@piece = current_user.pieces.find_by(id: params[:id])
redirect_to pieces_path, notice: "Access Denied! Not authorized to edit this piece." if @piece.nil?
end
def piece_params
params.require(:piece).permit(:title, :image, :genre, :size, :price, :description, :status)
end
end
谢谢你们!
答案 0 :(得分:0)
在correct_user
中,将redirect_to
上的条件更改为and return if @piece.nil? and current_user.id != 1
,然后在@piece = Piece.find(params[:id]) if current_user.id == 1
下面添加一个新行,该行仅在redirect_to ... and return
时运行没有。
(另外,您有current_user.pieces.find_by(id: ...)
,为简单起见,这可能只是.find(...)
。)
