[SOLVED] Custom types for document attributes
I am trying to get my types sorted out with the custom collection schema. I am trying to add my custom properties to Models.Document like this:
TypeScript
interface Picture extends Models.Document {
user_id: string,
name: string,
pic_id: string,
an: number,
descriere: string
}
And trying to use it like this:
TypeScript
db.listDocuments(..).documents.map((a: Picture) => {});
Except, it's not compatible: ts
Argument of type '(a: Picture) => { user_id: string; name: string; pic_id: string; an: number; descriere: string; }' is not assignable to parameter of type '(value: Document, index: number, array: Document[]) => { user_id: string; name: string; pic_id: string; an: number; descriere: string; }'.ts(2345)
What would be the solution?
TL;DR
The user was trying to add custom properties to the `Models.Document` type in TypeScript. They defined an interface `Picture` extending `Models.Document` with the custom properties but encountered an error when trying to use it. The error indicated that the argument type was not assignable. The solution is to use a type assertion to force the type compatibility. An example code sample was provided.
I think you need to force the assertion.
TypeScript
type Picture = Models.Document & {
user_id: string,
name: string,
pic_id: string,
an: number,
descriere: string
}
Basically it's the same as you but with a "type"
fixed it
thanks!
