Struggling with item update

[Amything 4]

I'm trying to update properties for an item. I'm probably doing something really basic wrong. My stripped down Python code is:

 

        url = "https://localhost:443"
        api_key = "xxx"
        user_id = "xxx"
        item_id = "123"

        header = {"X-MediaBrowser-Token": api_key}

        get_item_url = f"{url}/emby/users/{user_id}/items/{item_id}"
        response = requests.get(get_item_url, headers=header)
        item = response.json()  # Item gotten successfully

        item["Name"] = "Test name"

        update_item_url = f"{url}/emby/Items/{item_id}?api_key={api_key}"
        response = requests.post(update_item_url, data=json.dumps(item), headers=header)
        print(response.status_code, response.text)

 Result is: 500 The method or operation is not implemented.

OK if you use the web browser debugger to monitor what the web app sends, how does that compare to your request?

[TeamB 2352]

I had problems using this as well.

It is hard to get ALL the data you need to do the update, a standard cal to get item info does not appear to get all the item data you need to make the update call.

Even if I added all the fields used in the Web Client I still had the same error

Value cannot be null. (Parameter 'source')

So I gave up and wrote my own plugin that accepts just the details I want to update, not a good options but worked in my situation.

I think we need two things, the first one is the best option I feel.

- API endpoint that can just update a single or multiple details of an item, just fill in the Item details you want updated and call update
- Way of getting an Item that has all the fields needed to do the update.

@LukeThank you for that tip, using the web client to see exactly what is happening helped get me on the right track.

@TeamBYeah would be nice to just be able to modify a specific property. However I did manage to get it to work with simply posting the same item after getting it  previously.

My problem was doing:

data=item instead of json=item in the request.

Full working sample:
 

        url = self.server_url
        api_key = self.api_key
        user_id = self.user_id
        header = {"X-MediaBrowser-Token": api_key}
        item_id = "1389020"

        get_item_url = f"{url}/emby/users/{user_id}/items/{item_id}"
        response = requests.get(get_item_url, headers=header)
        item = response.json()

        item["Name"] = "Test name"
        update_item_url = f"{url}/emby/Items/{item_id}?api_key={api_key}"
        response = requests.post(update_item_url, json=item, headers=header)
        print(response.status_code, response.text)
