Why is there no "as" for HasMany/BelongsToMany in v7?

[pocketarc]

In v7, let's say I have the following example:

@HasMany(() => PostComments, {
    foreignKey: "post_id",
    as: "comments",
})

I get the following:

TS2353: Object literal may only specify known properties, and as does not exist in type
Omit<HasManyOptions<string, keyof PostCommentAttributes>, "as">

This happens with BelongsToMany as well.

Without the as, the key will be postComments, which is a bit more verbose than I'd like.

Why is the as omitted for these relationships? Is there no way to specify a custom key for these relationships?

Because the name of the association is also the name of the class field that will be used to access the eagerly loaded association, when using decorators, the name of the class field being decorated is automatically used as the as option

Oh, thank you! That's amazing, so if I have:

@HasMany(() => PostComments, "post_id")
declare comments?: NonAttribute<PostComments[]>;

It automatically knows that the "as" is "comments"! That's SO nice.

Exactly! :)
