How to attach file via "Bugzilla XMLRPC access module"

I am working on bugzilla xml-rpc by using "Bugzilla XMLRPC access module" developed in python.

How I can attach/download bugzilla file by using this module ?

According to guideline of API get_attachments_by_bug($bug_id) retrieves and returns the attachments.

But this function didn't worked for me, I got following error message.

<type 'exceptions.AttributeError'>: 'Bugzilla4' object has no attribute 'get_attachments_by_bug'

Any help would be appreciated.

Solution

FYI: I am in contact with supplier of python-bugzilla tool and here I got response from them.

"Not all bugzilla XMLRPC APIs are wrapped by python-bugzilla, that's one of them.

The 'bugzilla' command line tool that python-bugzilla ships has commands for attaching files and downloading attachments, take a look at the code there for guidance."

I've figured out the way how to download/upload attachment by using "Bugzilla XMLRPC access module"

you need to pass the id of attached file as parameter to the following function

Download:

downloaded_file = bz.download_attachment(attachment_id)
file_name = str(downloaded_file.name)

Upload:

kwards = {
    'contenttype':'application/octet-stream',
   # 'filename': file_path     #there could be more parameters if needed
} 

#attachfile method will return the id of attached file 
bz.attachfile(bug_id, file_path, file_name, **kwards)

However attached file got corrupted due to some xmp-rpc API's internal methods described here, here and here, that's another issue :)
