找不到 'id'= 的用户

Question

我知道这是最常见的问题，但我真的想在这里寻求帮助，因为我不明白我在这里做错了什么。

我生成了一个设计用户并打算为用户创建一个图库。以下是我试过的代码

型号 - Gallery.rb

class Gallery < ActiveRecord::Base
    belongs_to :user
end

控制器 - galleries_controller.rb

class GalleriesController < ApplicationController
  before_action :set_gallery, only: [:show, :edit, :update, :destroy]
  before_filter :authenticate_user!

  respond_to :html

  def index
    @user = User.find(params[:user_id])
    @galleries = Gallery.all
    respond_with(@galleries)
  end

  def show
    respond_with(@gallery)
  end

  def new
    @user = User.find(params[:user_id])
    @gallery = Gallery.new
    respond_with(@gallery)
  end

  def edit
  end

  def create
    @gallery = Gallery.new(gallery_params)
    flash[:notice] = 'Gallery was successfully created.' if @gallery.save
    respond_with(@gallery)
  end

  def update
    flash[:notice] = 'Gallery was successfully updated.' if @gallery.update(gallery_params)
    respond_with(@gallery)
  end

  def destroy
    @gallery.destroy
    respond_with(@gallery)
  end

  private
    def set_gallery
      @gallery = Gallery.find(params[:id])
    end

    def gallery_params
      params[:gallery, :user_id]
    end
end

由于我对 ROR 还是个新手，我们将不胜感激任何帮助。提前致谢。

Answer 1

从 URL 我假设你没有在参数中传递 user_id。

在你的路由文件库中应该是嵌套路由。如果你不想 user_id.

resources :users do
  resources :galleries do
  end
end

或者您可以使用

@user= current_user

找不到 'id'= 的用户

Couldn't find User with 'id'=
