Upload file and add properties

[Taaviansper]

I am trying to upload a file using python requests lib.

I have gotten the file upload working. using 

requests=(files={'filedata': open(file)})

But how can I add properties to the file to upload?

I have some links to possible solutions, but I have not gotten any of them to work.

I got it into a better state. But it still doesn't read the fields. The problem is things like parameter names. Alfresco Backend reads the file only with parameter 'filedata'. So what is the parameter 'data' or 'json' supposed to be? Is the structure wrong there?

I have a feeling you can't add the title/description/authors metadata in post request. 

I made a second PUT request right after a successful POST request ( you get the inserted object ID back with POST)

and i was able to add the props successfully

{"properties":{"cm:description":"blaah" etc. }

Hi @Taaviansper 

I've just tested using the API to upload a document with metadata successfully. 

I've used Postman to test the API and it will generate code - here is the Python code:

import requests

url = "http://localhost/alfresco/api/-default-/public/alfresco/versions/1/nodes/-my-/children?alf_ticket=TICKET_1d41b867df221a4d0edcd161d4df7570f1a07f98"

payload={'name': 'Marketing Automation.ppt',
'autoRename': 'true',
'cm:title': 'Marketing Automation',
'cm:description': 'A powerpoint about marketing and automation',
'exif:manufacturer': 'Canon',
'cm:author': 'Eddie May'}
files=[
  ('filedata',('Marketing_Automations_Trial.pptx',open('/Users/emay/Downloads/Marketing_Automations_Trial.pptx','rb'),'application/vnd.openxmlformats-officedocument.presentationml.presentation'))
]
headers = {
  'Authorization': 'Basic dGVzdDp0ZXN0'
}

response = requests.request("POST", url, headers=headers, data=payload, files=files)

print(response.text)

Note that in the payload I've set properties such as title & description. You can also see that it's a POST request.

The result in share is as follows:

MetadataYou can see from the creation date that I did it today (26 March 2021).

This should work from Alfresco 5.2 upwards. Here I'm testing against Community Edition 6.2.

HTH,
