Postman variable into string

Question

I feel kinda dumb asking this question bcs I might be missing something super easy but.. I have a collection of requests in Postman.

I have a collection variable test_model_id which is 888.

What I'm trying to achieve is simply putting the model_id variable into the string in resp_data line. I feel like I tried everything lol.

var model_id = parseInt(pm.collectionVariables.get("test_model_id"));

pm.test("Test_response_model_creation", function () {
    var jsonData = pm.response.text();
    var resp_data = JSON.stringify({"detail":"Model {{model_id}} created","HTTPStatusCode":200});
    pm.expect(jsonData).to.eql(resp_data);
});

Getting

... to deeply equal '{"detail":"Model {{model_id}} created","HTTPStatusCode":200}'

`detail: "Model " + model_id + " created"` or `detail: \`Model ${model_id} created\`` — , Jun 07 '21 at 14:39
string manipulation should do it: `"detail": "Model ${model_id} created"` — somallg, Jun 07 '21 at 14:39
This `"Model ${model_id} created"` is what I was trying and it didn't work. At `"Model " + model_id + " created"` I was a little scared it's gonna break the JSON format but it works. Thanks. — Leemosh, Jun 07 '21 at 14:43

Have you tried using template laterals?

var resp_data = JSON.stringify({"detail":`Model ${model_id}` created","HTTPStatusCode":200});

Sadly I didn't work with JS too much so I totally forgot about these. Thanks! – Leemosh Jun 07 '21 at 14:47
