Dropbox Python SDK support for Flask applications.


* `Python <>`_ 2.6 or 2.7
* `Flask <>`_ 0.8 or higher
* `Dropbox Python SDK <>`_ 1.4 or higher



$ pip install Flask-Dropbox


``Flask-Dropbox`` is licensed under the `BSD License



**REQUIRED.** As token would be stored in Flask's `session
<>`_ instance, you need to
configure secret key for your application.


**REQUIRED.** App key from Dropbox developer site.


**REQUIRED.** Secret key from Dropbox developer site.


**REQUIRED.** Should be ``'dropbox'`` or ``'app_folder'`` as configured for
your app.


By default, you don't need to provide this setting, cause ``Flask-Dropbox``
will setup callback URL automaticly usign current host and type of request,
but if you don't trust us, you could to rewrite this setting manually.


Template to be used for showing errors while trying to process oAuth callback
from Dropbox API. By default: ``'dropbox/callback.html'``.

Next boolean vars could be sent to the template:

* ``error_oauth_token`` - Dropbox API didn't return oAuth token.
* ``error_not_equal_tokens`` - oAuth token from Dropbox API is not equal to
request token stored in Flask session.
* ``error_response`` - Dropbox API returns ``ErrorResponse`` instance. Also
actual exception as ``error`` var would be sent to the template too.


Page to redirect to after user successfully logged in with Dropbox account. By
default: ``/``.


Page to redirect to after user logged out from authenticated Dropbox session.
By default: ``/``.


.. versionadded:: 0.3

Where to place account info, Dropbox client and Dropbox session instances. In
0.2 and lower all this info stored in ``flask_dropbox.Dropbox`` instance, which
isn't thread safe, but from 0.3 all these values stored to ``flask.g``. If you
need custom storage you can override this setting with object or string which
would be imported.



from flask import Flask
from flask.ext.dropbox import Dropbox, DropboxBlueprint

import settings

app = Flask(__name__)

dropbox = Dropbox(app)


SECRET_KEY = 'some-secret-key'
DROPBOX_KEY = 'dropbox-app-key'
DROPBOX_SECRET = 'dropbox-app-secret'
DROPBOX_ACCESS_TYPE = 'app_folder'


from flask import url_for, redirect, request
from werkzeug import secure_filename

from app import app, dropbox

def home():
return u'Click <a href="%s">here</a> to login with Dropbox.' % \

def success(filename):
return u'File successfully uploaded as /%s' % filename

@app.route('/upload', methods=('GET', 'POST'))
def upload():
if not dropbox.is_authenticated:
return redirect(url_for('home'))

if request.method == 'POST':
file_obj = request.files['file']

if file_obj:
client = dropbox.client
filename = secure_filename(file.filename)

# Actual uploading process
result = client.put_file('/' + filename,

path = result['path'].lstrip('/')
return redirect(url_for('success', filename=path))

return u'<form action="" method="post">' \
u'<input name="file" type="file">' \
u'<input type="submit" value="Upload">' \

Bugs, feature requests?

If you found some bug in ``Flask-Dropbox`` library, please, add new issue to
the project's `GitHub issues



+ Flask 0.10 support
+ Store account info, Dropbox client and session in thread-safe ``flask.g``
storage instead of ``flask_dropbox.Dropbox`` instance
+ Introduce ``DROPBOX_CACHE_STORAGE`` setting


+ Add ``init_app`` method to ``Dropbox`` extension class.
+ Do not send ``dropbox`` instance for initialization of ``DropboxBlueprint``
+ Use ``current_app.extensions['dropbox']`` statement in views for getting
initialized ``Dropbox`` instance.


+ Add ``register_blueprint`` shortcut to initialize ``DropboxBlueprint`` with
default values in one line.
+ Move ``Dropbox`` class from ``flask.ext.dropbox.utils`` to
``flask.ext.dropbox.extension`` module. But mainly, it wouldn't affected to
your code if you used ``from flask.ext.dropbox import Dropbox`` statements.


+ Add ``dropbox`` library as install requirement in ````.
+ Update project short description.


+ Fix handling templates while installing via


+ Add support of Dropbox SDK 1.4.1
