Nuxeo API Python client attachBlob, encode error ?
Hi,
I find the correct method to attach a blob with the python automation client (answer how-to-call-blobattach-via-rest-api-in-python)
Perfect for ascii files, but when i try to attach a blob like a pdf or a csv, I have an error UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 464: ordinal not in range(128) I am on Ubuntu 12.04 / python 2.7.6 / Nuxeo 5.8
Someone have an idea ?
Thanks

Hi,
I would suggest you use the latest version of the Python Automation client available in the python-automation-client branch of the https://github.com/nuxeo/nuxeo-automation-clients repository:
https://github.com/nuxeo/nuxeo-automation-clients/tree/python-automation-client/python
This is the result of the extraction of the Python Automation client used by Nuxeo Drive, which we put in a branch for the moment as work is still in progress. You will find:
- A README
- The Pyhton Automation client: automation_client.py
If you want to attach a blob to an existing Nuxeo document, the following lines should do:
import automation_client
client = automation_client.BaseAutomationClient('http://server:port/nuxeo', 'usernamme', password='*****')
blob = client.execute_with_blob_streaming('Blob.Attach', '/path/to/the/file/to/upload/my_file.pdf', filename='my_file.pdf', document='/default-domain/workspaces/TestPython/TestPDFUpload')
This should solve your problem, and has the advantage of:
- Using the latest Automation batch upload API (see http://doc.nuxeo.com/x/OYLZ) instead of a multipart POST
- Streaming the blob instead of fully loading it in memory!
Hope this helps!
