Question

我对猫鼬很陌生。使用 mongoose 5.11.14 我有一个基本的用户模式，我想用鉴别器扩展它。基本用户定义如下：

export type IBasicUser = mongoose.Document & IBasicUserProp;
const userSchema = new Schema<IBasicUser, IBasicUserModel>({
  ...
});

userSchema.statics.getSignKey = async function (id: string): Promise<string> {
  ...
};

export interface IBasicUserModel extends mongoose.Model<IBasicUser> {
  getSignKey(id: string): Promise<string>;
}

export const BasicUser = mongoose.model('User', userSchema);

这按预期工作。现在我想通过鉴别器扩展模式。我尝试了多种方法：

export type IUser = mongoose.Document & IUserProp & IBasicUserProp;

const userSchema = new Schema<IUser, mongoose.Model<any>>({
  ...
}, { timestamps: true, toObject: { virtuals: true }, toJSON: { virtuals: true } });

export const User: mongoose.Model<IUser> = BasicUser.discriminator('UserExtended', userSchema);

这有效，但静态方法 getSignKey() 不存在（Typescript 错误）。

我也试过如下：

export type IUser = mongoose.Document & IUserProp & IBasicUserProp;

const userSchema = new Schema<IUser, IUserModel>({
  ...
}, { timestamps: true, toObject: { virtuals: true }, toJSON: { virtuals: true } });

export interface IUserModel extends mongoose.Model<IUser> {
  getSignKey(id: string): Promise<string>;
}

export const User: mongoose.Model<IUser> = BasicUser.discriminator('UserExtended', userSchema);

这样我得到以下 TS 错误：

export const User: mongoose.Model<IUser> = BasicUser.discriminator('UserExtended', userSchema);

如何让鉴别器工作并访问静态方法？

猫鼬鉴别器无法访问静态方法和基本模型
