Issue
I want to map the return of the flower libary (/api/tasks) to a list of objects. Currently it returns multiple objects, but without the "list wrapper", so it's not possible to iterate that. API: https://flower.readthedocs.io/en/latest/api.html#get--api-tasks
Return is for example:
HTTP/1.1 200 OK
Content-Length: 1109
Content-Type: application/json; charset=UTF-8
Etag: "b2478118015c8b825f7b88ce6b660e5449746c37"
Server: TornadoServer/3.1.1
{
"e42ceb2d-8730-47b5-8b4d-8e0d2a1ef7c9": {
"args": "[3, 4]",
"client": null,
"clock": 1079,
"eta": null,
"exception": null,
"exchange": null,
"expires": null,
"failed": null,
"kwargs": "{}",
"name": "tasks.add",

}
}
Any ideas how to do that? I've tried the following thing:
export interface Tasks {
tasks: TaskWrapper[]
}
export interface TaskWrapper {
[uuid: string]: Task
}
export interface Task {
uuid: string,
state: string,
received: string,
}
Added example of Dragan leads to the following problem:
loadAllTasksFromFlower(): Observable<Task[]> {
return this.http.get<Task[]>("localhost:5566/api/tasks")
.pipe(map(response => Object.entries(response)
.map(entry => ({ uuid: entry[0], state: entry[1].state, received: entry[1].received }))
}
TS2322: Type 'Observable<{ uuid: string; state: TaskState; received: any; }[]>' is not assignable to type 'Observable<Task[]>'. Type '{ uuid: string; state: TaskState; received: any; }[]' is not assignable to type 'Task[]'. Type '{ uuid: string; state: TaskState; received: any; }' is missing the following properties from type 'Task': type, source, invoke, callback, and 3 more.
Solution
The way you organized the interfaces is good, you can put the items in the array in this way:
const tasks: Task[] = Object.entries(data).map(entry => ({
uuid: entry[0],
state: entry[1].state,
received: entry[1].received
}));
