将FuzzySearch与猫鼬一起使用时出现打字稿错误

在猫鼬模式中,我使用以下库:https://github.com/VassilisPallas/mongoose-fuzzy-searching

UserSchema.plugin(mongoose_fuzzy_searching, { fields: ['name'] });

然后在服务中,我像这样使用它:

export function fuzzySearchUser(name: string): Query<Array<IUser>>{
    return User.fuzzySearch(name)
}

现在在上面的返回行中出现以下Typescript错误:

Property 'fuzzySearch' does not exist on type 'Model<IUser, {}>'.ts(2339)

如果我将它作为具有类型函数的属性添加到IUser界面,也不能将其添加到架构,则没有帮助。

(接口IUser扩展了mongoose.Document)

您需要创建一个键入文件,因为此库不提供键入内容。试试看。

typings/mongoose-fuzzy-search

declare module 'mongoose-fuzzy-search' {
  import { Document, DocumentQuery, Model, Schema } from 'mongoose'

  export interface MongooseFuzzyOptions<T> {
    fields: (T extends Object ? keyof T : string)[]
  }

  export interface MongooseFuzzyModel<T extends Document, QueryHelpers = {}>
    extends Model<T, QueryHelpers> {
    fuzzySearch(
      search: String,
      callBack?: (err: any, data: Model<T, QueryHelpers>[]) => void
    ): DocumentQuery<T[], T, QueryHelpers>
  }

  function fuzzyPlugin<T>(schema: Schema<T>, options: MongooseFuzzyOptions<T>): void

  export default fuzzyPlugin
}

然后使用MogooseFuzzyModel声明模型:

export const User = mongoose.model<UserModel>('User', UserSchema) as MongooseFuzzyModel<UserModel>
