Installation
------------

Installing Tumbply is simple: ::

$ pip install python-tumblpy


Usage
-----

Authorization URL
~~~~~~~~~~~~~~~~~
::

# Without a dynamic callback url
# This will use the callback url specified in your app

# Go to http://www.tumblr.com/oauth/apps and click your
# app to find out your dynamic callback url
t = Tumblpy(app_key = '*your app key*',
app_secret = '*your app secret*')

If you wish to have a dynamic callback url, specify ``callback_url`` when you initiate the class.

::

t = Tumblpy(app_key = '*your app key*',
app_secret = '*your app secret*',
callback_url = 'http://example.com/callback/')

::

auth_props = t.get_authentication_tokens()
auth_url = auth_props['auth_url']

oauth_token = auth_props['oauth_token']
oauth_token_secret = auth_props['oauth_token_secret']

Connect with Tumblr via: % auth_url

Once you click "Allow" be sure that there is a URL set up to handle getting finalized tokens and possibly adding them to your database to use their information at a later date.

Handling the Callback
~~~~~~~~~~~~~~~~~~~~~
::

# oauth_token and oauth_token_secret come from the previous step
# if needed, store those in a session variable or something

t = Tumblpy(app_key = '*your app key*',
app_secret = '*your app secret*',
oauth_token=oauth_token,
oauth_token_secret=oauth_token_secret)

# In Django, you'd do something like
# oauth_verifier = request.GET.get('oauth_verifier')

oauth_verifier = *Grab oauth verifier from URL*
authorized_tokens = t.get_authorized_tokens(oauth_verifier)

final_oauth_token = authorized_tokens['oauth_token']
final_oauth_token_secret = authorized_tokens['oauth_token_secret']

# Save those tokens to the database for a later use?

Getting some User information
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

# Get the final tokens from the database or wherever you have them stored

t = Tumblpy(app_key = '*your app key*',
app_secret = '*your app secret*',
oauth_token=final_tokens['oauth_token'],
oauth_token_secret=final_tokens['oauth_token_secret'])

# Print out the user info, let's get the first blog url...
blog_url = t.post('user/info')
blog_url = blog_url['user']['blogs'][0]['url']

Get a User Avatar URL (No need for authentication for this method)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

t = Tumblpy()
avatar = t.get_avatar_url(blog_url='omglegit.tumblr.com', size=128)
print avatar['url']

# OR

avatar = t.get('avatar', blog_url='omglegit.tumblr.com'. extra_endpoints=['128'])
print avatar['url']

Getting posts from a certain blog
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

# Assume you are using the blog_url and Tumblpy instance from the previous section
posts = t.get('posts', blog_url=blog_url)
print posts

Creating a post with a photo
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

# Assume you are using the blog_url and Tumblpy instance from the previous sections

photo = open('/path/to/file/image.png', 'rb')
post = t.post('post', blog_url=blog_url, params={'type':'photo', 'caption': 'Test Caption', 'data': photo})
print post # returns id if posted successfully

Posting an Edited Photo *(This example resizes a photo)*
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::

# Assume you are using the blog_url and Tumblpy instance from the previous sections

# Like I said in the previous section, you can pass any object that has a
# read() method

# Assume you are working with a JPEG

from PIL import Image
from StringIO import StringIO

photo = Image.open('/path/to/file/image.jpg')

basewidth = 320
wpercent = (basewidth / float(photo.size[0]))
height = int((float(photo.size[1]) * float(wpercent)))
photo = photo.resize((basewidth, height), Image.ANTIALIAS)

image_io = StringIO.StringIO()
photo.save(image_io, format='JPEG')

image_io.seek(0)

try:
post = t.post('post', blog_url=blog_url, params={'type':'photo', 'caption': 'Test Caption', 'data': photo})
print post
except TumblpyError, e:
# Maybe the file was invalid?
print e.message

Following a user
~~~~~~~~~~~~~~~~
::

# Assume you are using the blog_url and Tumblpy instance from the previous sections
try:
follow = t.post('user/follow', params={'url': 'omglegit.tumblr.com'})
except TumblpyError:
# if the url given in params is not valid,
# Tumblr will respond with a 404 and Tumblpy will raise a TumblpyError

Catching errors
~~~~~~~~~~~~~~~
::

try:
t.post('user/info')
except TumbplyError, e:
print e.message
print 'Something bad happened :('
