python dropbox api error

Question

I'm following the tutorial here

So far so good but the upload example give me errors. The code:

from dropbox import client, rest, session

f = open('txt2.txt') # upload a file
response = client.put_file('/magnum-opus.txt', f)
print "uploaded:", response

The error:

Traceback (most recent call last):
  File "dropbox_ul.py", line 4, in <module>
    response = client.put_file('/magnum-opus.txt', f)
AttributeError: 'module' object has no attribute 'put_file'

Where did I go wrong?

EDIT: The new code I'm trying. This is actually from the dropbox developer website. As I stated earlier, I did go through the authentication and setup:

# Include the Dropbox SDK libraries
from dropbox import client, rest, session

# Get your app key and secret from the Dropbox developer website
APP_KEY = 'iqxjea6s7ctxv9j'
APP_SECRET = 'npac0nca3p3ct9f'

# ACCESS_TYPE should be 'dropbox' or 'app_folder' as configured for your app
ACCESS_TYPE = 'dropbox'

sess = session.DropboxSession(APP_KEY,APP_SECRET, ACCESS_TYPE )

request_token = sess.obtain_request_token()

# Make the user sign in and authorize this token
url = sess.build_authorize_url(request_token)
print "url:", url
print "Please authorize in the browser. After you're done, press enter."
raw_input()

# This will fail if the user didn't visit the above URL and hit 'Allow'
access_token = sess.obtain_access_token(request_token)

client = client.DropboxClient(sess)
print "linked account:", client.account_info()

f = open('txt2.txt')
response = client.put_file('/magnum-opus.txt', f)
print "uploaded:", response

folder_metadata = client.metadata('/')
print "metadata:", folder_metadata

f, metadata = client.get_file_and_metadata('/magnum-opus.txt',rev='362e2029684fe')
out = open('magnum-opus.txt', 'w')
out.write(f)
print(metadata)

and the error:

   url: https://www.dropbox.com/1/oauth/authorize?oauth_token=jqbasca63c0a84m
    Please authorize in the browser. After you're done, press enter.

Answer 1

You haven't initialized the client object. Refer to the tutorial again and you'll see this:

client = client.DropboxClient(sess)

The sess object must also be initialized before calling the client module's DropboxClient method:

sess = session.DropboxSession(APP_KEY, APP_SECRET, ACCESS_TYPE)

You should have all the required parameters (i.e., APP_KEY, APP_SECRET, ACCESS_TYPE) assigned to you when you register your application.

Answer 2

I followed the edited code of yours and things worked out perfectly.

from dropbox import client, rest, session

# Get your app key and secret from the Dropbox developer website
app_key = 'enter-your-app_key'
app_secret = 'enter-your-app_secret'

ACCESS_TYPE = 'dropbox'

sess = session.DropboxSession(app_key, app_secret, ACCESS_TYPE )

request_token = sess.obtain_request_token()

# Make the user sign in and authorize this token
url = sess.build_authorize_url(request_token)
print "url:", url
print "Please authorize in the browser. After you're done, press enter."
raw_input()

# This will fail if the user didn't visit the above URL and hit 'Allow'
access_token = sess.obtain_access_token(request_token)

client = client.DropboxClient(sess)
print "linked account:", client.account_info()

f = open('/home/anurag/Documents/sayan.odt')
response = client.put_file('/sayan.odt', f)
print "uploaded:", response

Notice the response and file location on your system, in your code that doesn't matches.

Thanks.
