Azure Cosmos DB, Delete IDS (definitely exist)

问题

This is probably a very simple and silly mistake but I am unsure of how this is failing. I have used the https://github.com/Azure/azure-cosmos-python#insert-data tutorial. How can I query a database then used those ids to delete and then they don't exist.

Can anyone help before the weekend sets in? Thanks, struggling to see how this fails!

Error:

This is my code...

def get_images_to_check(database_id, container_id):
    images = client.QueryItems("dbs/" + database_id + "/colls/" + container_id,
                                        {
                                                'query': 'SELECT * FROM c r WHERE r.manually_reviewed=@manrev',
                                                'parameters': [
                                                    {'name': '@manrev', 'value': False}
                                                ]
                                        },
                                        {'enableCrossPartitionQuery': True})
    return list(images)

def delete_data(database_id, container_id, data):
    for item in data:
        print(item['id'])
        client.DeleteItem("dbs/" + database_id + "/colls/" + container_id + "/docs/" + item['id'], {'partitionKey': 'class'})

database_id = 'ModelData'
container_id = 'ImagePredictions'
container_id = 'IncorrectPredictions'
images_to_check = get_images_to_check(database_id, container_id)
delete_data(database_id, container_id, images_to_check)```

回答1:

When specifying the partition key in the call to client.DeleteItem(), you chose:

{'partitionKey': 'class'}

The extra parameter to DeleteItem() should be specifying the value of your partition key.

Per your comments, /class is your partition key. So I believe that, if you change your parameter to something like:

{'partitionKey': 'value-of-partition-key'}

This should hopefully work.

回答2:

More than likely the issue is with mismatched id and PartitionKey value for the document. A document is uniquely identified in a collection by combination of it's id and PartitionKey value.

Thus in order to delete a document, you need to specify correct values for both the document's id and it's PartitionKey value.
