我正在开发Rails 5.2应用程序,我已经安装并设置了active_storage,但是,我似乎无法编辑或显示rails凭据.

这是错误的输出

这是课程控制器

class CoursesController < ApplicationController
  layout proc { user_signed_in? ? "dashboard" : "application" }

  before_action :set_course, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except: [:index, :show]
  before_action :authorize_admin, except: [:index, :show, :complete]

  def index
    @courses = Course.all.order(created_at: :asc)
  end

  def show
    course = Course.friendly.find(params[:id])
    @course_modules = course.course_modules.order(created_at: :asc)
  end

  def new
    @course = Course.new
  end

  def edit
  end

  def create
    @course = Course.new(course_params)

    respond_to do |format|
      if @course.save
        format.html { redirect_to courses_path, notice: 'Course was successfully created.' }
        format.json …

我有两个模式，一个集合，另一个类别。一个集合有很多类别，一个类别可以有很多集合项。

我希望稍后再创建一个过滤器。

类别架构

const mongoose = require('mongoose')

let categorySchema = new mongoose.Schema({
  name: {
    type: String,
    required: true,
    unique: true
  },
  collections: [{ type: mongoose.Types.ObjectId, ref: 'Collection' }]
})

module.exports = mongoose.model('category', categorySchema)

收集模式

const mongoose = require('mongoose')

let collectionSchema = new mongoose.Schema({
  ...
  categories: [{
    type: mongoose.Schema.Types.ObjectId, ref: 'categories',
    required: true
  }]
})

module.exports = mongoose.model('collection', collectionSchema)

截断此内容以保持相关性。

我现在不打算填充引用，因为我现在只是在做后端，所以我现在仅渲染JSON。

我可以创建多个类别

并且我可以创建一个具有类别的集合，因为一个集合必须至少具有一个类别

我可以编辑收藏夹并添加新类别

但是，有时我似乎收到以下错误

我不确定为什么应用程序中的数据库可能没有更新，我使用的是nodemon，所以我不太确定问题可能在这里。
