The presence of this container with Mongoose Schema Typescript eclipses an external 'this' value

Question

The presence of this container with Mongoose Schema Typescript eclipses an external 'this' value

Here's my schema validator code for MongoDB:

UserSchema.path('email').validate(async function (email: string) {
  const count = await User.count({ email, _id: { $ne: this._id } })
  return !count
}, 'Email already exists')

However, I'm encountering the following error:

'this' implicitly has type 'any' because it does not have a type annotation.ts(2683)
User.ts(171, 35): An outer value of 'this' is shadowed by this container.

This issue arises in my User.ts file. The functionality works as intended, but this Typescript error is causing problems during CI. Is there a solution to resolve this hiccup?

Answer №1

Give this a shot:

UserSchema.path('email').validate(async function (this:any, email: string) {
  const count = await User.count({ email, _id: { $ne: this._id } })
  return !count
}, 'Email already exists')

Your custom type can be used instead of "any".
