Uploadable

Check if the input value is a hash of Uploadable.

This rule is a database dependent rule. It requires a database connection to run against the input value.

The validation rule requires a value to run against the input value.

Basically it works by uploading the files in a separate request then attach the upload hash to certain model, i.e user avatar, post image etc.

Example

src/app/posts/controllers/create-post.ts

// ...
createPost.validation = {
  rules: {
    title: ["required", "stringify"],
    image: ["required", "uploadable"],
  },
};

The rule will fetch the uploads collection for the given hash and check if the hash exists, if not exists, the validation will fail.
