Example for using the "create_attachment" function?

[TheMechanic97]

I have tried using the path to a file as the upload_stream as well as opening the file to use the contents.

Using the path returns an ID and URL but they lead to a null (File does not exist) exception.

Using the contents of the file result in "'utf8' codec can't decode byte 0xff in position 0: invalid start byte".

Similar issue to #29. When we fix #29, this should be fixed as well.

Fix is in #163

The fix has been released in 0.1.24

Example method to upload a file and link it as a work item attachment:

def upload_work_item_attachment(wit_client, work_item_id, file_name, callback=None):
    # upload file / create attachment
    with open(file_name, 'r+b') as file:
        # use mmap, so we don't load entire file in memory at the same time, and so we can start
        # streaming before we are done reading the file.
        mm = mmap.mmap(file.fileno(), 0)
        attachment = wit_client.create_attachment(mm, file_name=file_name, callback=callback)

    # Link Work Item to attachment
    patch_document = [
        JsonPatchOperation(
            op="add",
            path="/relations/-",
            value={
                "rel": "AttachedFile",
                "url": attachment.url
            }
        )
    ]
    wit_client.update_work_item(patch_document, work_item_id)
