Help with Stock merging via API

[SebBorbely]

I am trying to merge multiple stock items of a part into one via the api so that i can update the total quantity in one. I am having some trouble with the required filed "items". I have tried many different ways of writing it but i always get the same error when running the python code.
{"items":{"non_field_errors":["Expected a list of items but got type "str"."]}}

heres what i currently have for the stock_merge_create API endpoint:

# Make the merge API request
    
response = api.post("stock/merge/", {
            "items": [
                {
                    "item": 1973,
                    "item": 1974
                },
            ],
            "location": 1,
            })

1973 and 1974 are the item stock ids (pks) i am trying to merge.
Any help on this would be appreciated.

I think you need to split the "items" into a proper list of dict objects, rather than a list with a single dict inside

# Make the merge API request
response = api.post("stock/merge/", {
            "items": [
                {
                    "item": 1973,
                },
                {
                    "item": 1974
                },
            ],
            "location": 1,
            })

So I tried that. Still getting the same error of:
{"items":{"non_field_errors":["Expected a list of items but got type "str"."]}}

Just to make sure I didn't get something else in the code wrong which might be causing the error I swapped out the merge to an add stock like this and that worked no issue.

response = api.post("stock/", {
            "part": 437,  # Replace with a valid part ID
            "quantity": 11,
            "location": 1  # Replace with a valid location ID
        })

I've tried many different versions on how to get it to recognise it as an object but non seem to work.
Just for extra info incase it matters im running inventree version:

The following worked for me, against the demo server:

from inventree.api import InvenTreeAPI
api = InvenTreeAPI(
    'https://demo.inventree.org',
    username = 'admin',
    password = 'inventree',
    )

data = {'items': [{'item': 408}, {'item': 1223}], 'location': 38}

api.post("stock/merge/", data)
{'items': [{'item': 408}, {'item': None}], 'location': 38}

Maybe you can try with the demo server also?

[SebBorbely]

Tried running same exact code as you both on my server with my API token and on the demo server using the logins.

from inventree.api import InvenTreeAPI
api = InvenTreeAPI(
    'https://demo.inventree.org',
    username = 'admin',
    password = 'inventree',
    )

data = {'items': [{'item': 1363}, {'item': 408}], 'location': 38}

api.post("stock/merge/", data)

Still getting the same response.

POST request failed at 'https://demo.inventree.org/api/stock/merge/' - 400
{"items":{"non_field_errors":["Expected a list of items but got type \"str\"."]}}

Is there some setup I'm missing? Thought as I can add stock and change quantity it should all be good with merging as well.
I am just running it as a python code. Is that fine?
Sorry new to all this API stuff so sticking quite closely to tutorials and examples.

[miggland]

Strange. Which version of InvenTreeAPI are you using?

[SebBorbely]

[miggland]

I meant which version of the Python binding inventree-python..

But your server is kind of old, older than the Demo server for sure..

[SebBorbely]

Thank you. All solved now after an update. Just running too old stuff.

[SchrodingersGat]

The following code worked fine for me:

from inventree.api import InvenTreeAPI


SERVER = "http://127.0.0.1:8000"
USER = "admin"
PASS = "inventree"

api = InvenTreeAPI(SERVER, username=USER, password=PASS)

response = api.post(
    "stock/merge/",
    {
        "items": [
            {
                "item": 330,
            },
            {
                "item": 1359
            }
        ],
        "location": 1,
    }
)

I am using version 0.17.5 of the python bindings (you can find this out with the command pip show inventree):

[SebBorbely]

Thank you for the help. It seems the issue was that I was just running on too old stuff. Got it all working after updating the api and the inventree server.
