Question

我得到了如下嵌套资源错误：

ActiveRecord :: RecordNotFound位于/ admin / projects / 2 / project_comments

无法找到带有'id'=

的项目

的routes.rb

namespace :admin do
resources :users
resources :projects do
  resources :project_users
  resources :project_comments
end
end

project.rb

has_many :project_comments

project_comment.rn

belongs_to :project

project_comments_co

class Admin::ProjectCommentsController < ApplicationController
before_action :set_project_comment, only: [:show, :edit, :update, :destroy]  
before_action :set_project


def your_action
    # these are for debugging
    puts params.inspect
    puts params[:option_id]
    @event = Event.find(params[:event_id])
    @option = Option.find(params[:option_id])
end

def index
    @project_comments = @project.project_comments.all
end

def new
    @project_comment = @project.project_comments.new
end

def create
    @project_comment = @project.project_comments.new(project_comment_params)

    if @project_comment.save
    else
    end
end

def show
end

def edit
end

def update
    if  @project_comment.update(project_comment_params)
    else
    end
end

def destroy
    @project_comment.destroy
end

private
def set_project
    @project = Project.find(params[:id])
end


def set_project_comment
    @set_project_comment = ProjectComment.find(params[:id])
end


def project_comment_params
    params.require(:project_comment).permit(:project_id, :user_id, :comment)    
end

感谢您帮助我！

Answer 1

此错误表示Rails无法使用此ID找到任何项目记录。

数据库中是否有任何项目记录？

请发布堆栈跟踪。

Answer 2

使用以下代码更改set_project函数：

private 
def set_project 
  @project = Project.find(params[:project_id]) 
end

Answer 3

当你在ProjectCommentsController内时，params[:id]将id ProjectComment而不是Project。所以在你的方法中：

def set_project
    @project = Project.find(params[:id])
end

将params[:id]更改为params[:project_id]，这将解决您的问题。

ruby-找不到'id'=的项目
