Dropbox Python SDK support for Flask applications.

Requirements
============

* `Python <http://www.python.org/>`_ 2.6 or 2.7
* `Flask <http://flask.pocoo.org/>`_ 0.8 or higher
* `Dropbox Python SDK <http://pypi.python.org/pypi/dropbox>`_ 1.4 or higher

Installation
============

::

$ pip install Flask-Dropbox

License

``Flask-Dropbox`` is licensed under the `BSD License
<https://github.com/playpauseandstop/Flask-Dropbox/blob/master/LICENSE>`_.

Configuration
=============

SECRET_KEY
----------

**REQUIRED.** As token would be stored in Flask's `session
<http://flask.pocoo.org/docs/quickstart/#sessions>`_ instance, you need to
configure secret key for your application.

DROPBOX_KEY
-----------

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

DROPBOX_SECRET
--------------

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

DROPBOX_ACCESS_TYPE
-------------------

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

DROPBOX_CALLBACK_URL
--------------------

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.

DROPBOX_CALLBACK_TEMPLATE
-------------------------

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.

DROPBOX_LOGIN_REDIRECT
----------------------

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

DROPBOX_LOGOUT_REDIRECT
-----------------------

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

DROPBOX_CACHE_STORAGE
---------------------

.. 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.

Usage
=====

``app.py``::

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

import settings


app = Flask(__name__)
app.config.from_object(settings)

dropbox = Dropbox(app)
dropbox.register_blueprint(url_prefix='/dropbox')

``settings.py``::

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

``views.py``::

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

from app import app, dropbox


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


@app.route('/success/<path:filename>')
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, file_obj.read())

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">' \
u'</form>'
