How to use validator in mongoose schema in typescipt?-CodePudding

I was using a validator to validate my passwordConfirm matching with a password. It was working fine on js but now as I am moving to ts I am facing an error. Please solve my issue Thanks.

const UserSchema = new Schema(
  {
      password: {
      type: String,
      required: [true, 'Password is required'],
    },
    passwordConfirm: {
      type: String,
      required: [true, 'PasswordConfirm is required'],
      validate: {
        // This only works on CREATE and SAVE!!!
        validator(el: string) {
          return el === this.password; // error on this line on "this" keyword
        },
        message: 'Passwords are not the same!',
      },
    },
}
and this is the error i am facing

Property 'password' does not exist on type 'Function | String | RegExp | { [path: string]: SchemaDefinitionProperty<undefined>; } | typeof SchemaType | Schema<any, any, any> | ... 18 more ... | ({ ...; } | { ...; })[]'.
  Property 'password' does not exist on type 'Function'.

CodePudding user response：

First, you should not save passwordConfirm field in the schema. passwordConfirm should just be used for validation on the backend. The correct way to do this;

UserSchema.pre("save", async function(next) {
    if (this.password && this.passwordConfirm) {
       let isSame = this.password === this.passwordConfirm;
       if(!same){
             throw error ("Password and Confirm password did not match")
          }
    }
    next();
});
