Question

尝试通过嵌入文档来建立馆藏之间的关系模型但是在模式中进行验证并将“ required”设置为True时，就会出现err

一旦我解决了电影模式中的流派对象所需的问题，便会对此进行评论但我要验证

const Movie = mongoose.model(
  'Movies',
  new mongoose.Schema({
    title: {
      type: String,
      required: true,
      trim: true,
      minlength: 1,
      maxlength: 255
    },
    numberInStock: {
      type: Number,
      required: true,
      min: 0,
      max: 255
    },
    dailyRentalRate: {
      type: Number,
      required: true,
      min: 0,
      max: 255
    },
    genre: genreSchema
    required: true
  })
);

const genreSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true,
    minlength: 5,
    maxlength: 50
  }
});

TypeError：无效的架构配置：True在路径required处不是有效类型

Answer 1

尝试在true旁边给出消息。例如->必填：[true，“ Title required”]

Answer 2

您可以在提取

时使用引用并使用填充

genre: [{
        type: mongoose.Schema.Types.ObjectId,
        ref: 'genreSchema',
        required: true
    }],

参考：Model Referenced one to Many Relationship between documents 进行更好的架构设计

Answer 3

请共享完整代码。

也许主要原因是您没有使用

const Movie = mongoose.model(
  'Movies',
  new mongoose.Schema({
    title: {
      type: String,
      required: true,
      trim: true,
      minlength: 1,
      maxlength: 255
    },
    numberInStock: {
      type: Number,
      required: true,
      min: 0,
      max: 255
    },
    dailyRentalRate: {
      type: Number,
      required: true,
      min: 0,
      max: 255
    },
    genre: {
        ref: 'SchemaName',
        required: true
    },
  })
);

您可以这样做。

Answer 4

将流派模型导出为 exports.genreSchema = genreSchema

然后在movies.js文件中将模型导入为 import { genreSchema } from './genre.model'

尝试执行此操作将不会出现错误。

Answer 5

删除required: true，然后从官方docs中删除。注意所用猫鼬的版本。我遇到了同样的错误并解决了。我的错误是使子文档成为模型，而不是将其保留为模式

const childSchema = new Schema({ name: 'string' });

const parentSchema = new Schema({
  // Array of subdocuments
  children: [childSchema],
  // Single nested subdocuments. Caveat: single nested subdocs only work
  // in mongoose >= 4.2.0
  child: childSchema
});

猫鼬验证错误：无效的架构配置
