The datatype 'number' cannot be assigned to the className array type[]

I encountered an error message:

When attempting to assign a 'number' value, I get the following error: Type 'number' is not assignable to type DeviceInput []

Here's the code that triggered the issue:

id:number
reprobj:Reprocess;
this.reprobj.DeviceIds=this.id;

This is how the model class is structured:

export class DeviceInput
{
    ID:number
}

export class Reprocess
{
    Flag:boolean
    ProductID:number
    DeviceIds: DeviceInput[]
}

Any suggestions on how to resolve this problem?

Answer №1

Here is an example of an array in code:

DeviceIds: DeviceInput[]

And here is a number variable declaration:

id:number

You cannot assign a number to an array directly. To resolve this, you need to make some adjustments in your code:

export class DeviceInput
{
    ID: number;

    constructor(_id:number) {
        this.ID = _id;
    }
}

export class Reprocess
{
    Flag: boolean;
    ProductID: number;
    DeviceIds: DeviceInput[] = [];
}

To add a new DeviceInput instance to the DeviceIds array, you can use the following line of code:

this.reprobj.DeviceIds.push(new DeviceInput(someId));
