Stormpath Python SDK

Stormpath is the first simple and secure user management and authentication service for developers like you. This Python SDK makes using Stormpath with your application a painless, and even enjoyable process.

NOTE: This library will NOT work on Google App Engine due to incompatibility with the requests package.

Install

To get started, install the stormpath library using Pip.

$ pip install stormpath

If this doesn't work, you might need to install pip on your computer. See the Pip installation guide for more information.

Quickstart Guide

If you have not already done so, register as a developer on Stormpath, and create (and download) an API Key pair (this consists of an APIKeyID and an APIKeySecret).

When you first create your API Key pair using the Stormpath interface, you'll be prompted to download a file named apiKey.properties. This file contains your API Key pair information, which you'll need below.

Create a Client

Next, you'll want to create a Stormpath API client. You can do this in a few ways:

from stormpath.client import Client

# 1) By using the apiKey.properties file you previously downloaded.
client = Client(api_key_file='/path/to/apiKey.properties')

# 2) By specifying your API Key pair credentials manually.
client = Client(
    api_key_id = STORMPATH_API_KEY_ID,
    api_key_secret = STORMPATH_API_KEY_SECRET,
)

# 3) By setting an environment variable called STORMPATH_API_KEY_FILE to the
#    path of your apiKey.properties file.
client = Client()

# 4) By setting environment variables called STORMPATH_API_KEY_ID and
#    STORMPATH_API_KEY_SECRET which contain your keys.
client = Client()

# 5) By defining a file in ~/.stormpath/apiKey.properties -- this file will be
#    used automatically if it exists and no other credentials are specified.
client = Client()

NOTE: Once you've created a client, you can use it for the life of your application. There's no need to recreate a new client for each new request -- the client is smart, and will smartly handle SDK requests.

List Your Applications and Directories

To view a list of all your Stormpath Applications and Directories, you can easily iterate through the client.applications and client.directories generators show below:

for application in client.applications:
    print 'Application (name):', application.name
    print 'Application (href):', application.href

for directory in client.directories:
    print 'Directory (name):', directory.name
    print 'Directory (href):', directory.href

Retrieve a Given Application and Directory

If you know the full Application and Directory href (like the ones show in the previous example), you can easily retrieve the application and directory objects directly, like so:

application = client.applications.get('https://api.stormpath.com/v1/applications/<uid>')
directory = client.directories.get('https://api.stormpath.com/v1/directories/<uid>')

Easy, right?

Create an Application

As you can probably guess, creating an Application is also simple business.

The example below shows you how to create an Application by itself, or, if you want, an Application and a Directory together!

The benefits to creating them at the same time is that all the association stuff is handled automatically!

# Create an Application by itself.
application = client.applications.create({
    'name': 'Instagram',
    'description': 'A place to post photos of your food.',
})

# Create an Application AND Directory.
application = client.applications.create({
    'name': 'Instagram',
    'description': 'A place to post photos of your food.',
}, create_directory=True)

Create an Account in an Application

Now that you've (hopefully!) already created an Application and associated Directory, we can now move on to creating a user Account.

You can create a new Account on either an Application or Directory instance:

# Create a new Account on an Application instance.
emusk = application.accounts.create({
    'given_name': 'Elon',
    'surname': 'Musk',
    'email': 'emusk@spacex.com',
    'password': 'KINGofSPACE!W00',
})

# Create a new Account on a Directory instance.
pgraham = directory.accounts.create({
    'given_name': 'Paul',
    'surname': 'Graham',
    'email': 'paul@ycombinator.com',
    'username': 'pg',
    'password': 'STARTUPSar3th3b3sT!',
})

Update an Account

Once you have a few Accounts created, updating them is equally simple:

pgraham.middle_name = 'Iceman'
pgraham.save()

Authenticate an Account

Now that you have some user Accounts, we'll cover how you can securely check a user's credentials:

from stormpath.error import Error as StormpathError

try:
    auth_attempt = application.authenticate_account('pg', 'STARTUPSar3th3b3sT!')
except StormpathError, err:
    print 'Human friendly error message:', err.message
    print 'Developer friendly error message:', err.developer_message

Send a Password Reset Email

It's often very useful to be able to reset a user's account password. Doing this is simple using the send_password_reset_email method:

application.send_password_reset_email('emusk@spacex.com')

Create a Group

In Stormpath, the best way to think about roles and permissions is with Groups. Groups allow you to categorize Accounts, and build complex permissions systems.

Creating a new Group is easy:

directory.groups.create({
    'name': 'Administrators',
    'description': 'This group holds all Administrator accounts with *full* system access.',
})

Add an Account to a Group

To add an Account to a Group, just do the following:

group.add_account(pgraham)

NOTE: An Account may belong to an infinite number of Groups.

Store Custom Account Data

One of the newest (and most popular) of Stormpath's features is the ability to store variable data with each Account instance.

The example below stores some custom data:

pgraham.custom_data['favorite_company'] = 'Stormpath'
pgraham.custom_data['millions_invested'] = 99.999999
pgraham.custom_data['billions_acquired'] = 5
pgraham.custom_data['favorite_movie'] = 'The Lion King'
pgraham.custom_data.save()

print 'All custom data:', dict(pgraham.custom_data)

NOTE: None of the custom data entered above is actually saved to Stormpath until the .save() method is called.

Common Uses

Below you'll find information on using our Python SDK to accomplish commonly requested tasks.

Accessing Resources

Most of the work you do with Stormpath is done through the Applications and Directories you have created.

If you know what your Application or Directory href is, you can fetch the instance directly:

application = client.applications.get(application_url)
directory = client.directories.get(directory_url)

The applications and directories properties on the client instance allow you to iterate through all existing Applications and Directories, respectively.

for application in client.applications:
    print '%s (%s)' % (application.name, application.href)

NOTE: If you have a lot of Applications, the above code snippet will take a while to run, as it will iterate through all applications.

There are, of course, other resources available to iterate through, as well!

If you're on a Client instance, you can iterate through the following objects:

applications - Iterate through all Applications.
directories - Iterate through all Directories.
tenant - A single link to your current Tenant.

If you're on an Application instance, you can iterate through the following objects:

accounts - Iterate through all Accounts.
groups - Iterate through all Groups.
tenant - A single link to your current Tenant.

If you're on a Directory instance, you can iterate through the following objects:

accounts - Iterate through all Accounts.
groups - Iterate through all Groups.
tenant - A single link to your current Tenant.

If you're on a Group instance, you can iterate through the following objects:

accounts - Iterate through all Accounts.
tenant - A single link to your current Tenant.

Registering New Accounts

When creating new Accounts in Stormpath, you have several options.

There are only 4 required fields for each new Account you create:

given_name - The user's first name.
surname - The user's last name.
email - The user's email address.
password - The user's plain text password -- this will be hashed and securely stored when sent to Stormpath.

There are several other optional fields which can be used:

middle_name - The user's middle name.
status - The user's status (can be one of: 'enabled', 'disabled', 'unverified').
custom_data - A dictionary of custom user data (up to 10MB, per user).
username - A username.

If you have custom Stormpath workflows configured (rules that say what passwords are allowed, if email verification is required, etc.), you can optionally choose to create a new user account and skip applying these workflow rules by using the registration_workflow_enabled flag:

# This example will skip over the normal workflow you've got configured, and
# just create the user.
account = directory.accounts.create({
    'given_name': 'Michael',
    'surname': 'Bay',
    'middle_name': 'BOOM!',
    'email': 'michael@bay.com',
    'password': 'ILOVE3xpl0si0ns!!!!!',
}, registration_workflow_enabled=False)

If the Directory has been configured with an email verification workflow and a non-Stormpath URL, you have to pass the verification token sent to the URL in a sptoken query parameter back to Stormpath to complete the workflow. This is done through the verify_email_token on the accounts collection.

Authentication

When you authenticate users, you can provide either the username OR email, and password fields. This way you can accept registration using only email and password, username and password, or email, username, and password.

When users are successfully authenticated, an AuthenticationResult object will be return, with the Account attached.

To check for successful authentication, you should do something like the following:

from stormpath.error import Error as StormpathError

try:
    account = application.authenticate_account('username_or_email',
    'password').account
except StormpathError, err:
    print 'Human friendly error message:', err.message
    print 'Developer friendly error message:', err.developer_message
except Exception, err:
    print 'Something unexpected happened:', err

Password Reset

A password reset workflow, if configured on the Directory the Account is registered on, can be kicked off with the send_password_reset_email method on an Application:

application.send_password_reset_email('john.smith@example.com')

If the workflow has been configured to verify through a non-Stormpath URL, you can verify the token sent in the query parameter sptoken with the verify_password_reset_token method on the Application.

With the Account acquired you can then update the password:

account.password = new_password
account.save()

NOTE: Confirming a new password is left up to the web application code calling the Stormpath SDK. The SDK does not require confirmation.

ACL Through Groups

Memberships of Accounts in certain Groups can be used as an authorization mechanism. As the groups collection property on an Account instance is iterable, you can use any of that module's methods to determine if an Account belongs to a specific Group.

You can create Groups and assign them to Accounts using the Stormpath web console, or programmatically

Creating a Group is easy, just call the create method from your Directory instance:

group = directory.groups.create({'name': 'Administrators'})

Group membership can be created by:

Explicitly creating a GroupMembership resource with your client:

group_memebership = client.group_memberships.create(group, account)

Using the add_group method on the Account instance:
```
account.add_group(group)
```
Using the add_account method on the Group instance:
```
group.add_account(account)
```

Managing Custom Data

Groups and Accounts have CustomData fields that act as a dictionary:

Accessing custom data field:

print account.custom_data['favorite_color']
print group.custom_data['favorite_api_company']

Creating or updating a CustomData field:

account.custom_data['rank'] = 'Captain'
account.custom_data.save()

group.custom_data['affiliation'] = 'NCC-1701'
group.custom_data.save()

Deleting a CustomData field:

del account.custom_data['rank']
del group.custom_data['affiliation']

Saving CustomData changes (creates, updates and deletes) to Stormpath only take place when save() is explicitly called.
```
account.custom_data.save()
group.custom_data.save()
```
OR
```
account.save()
group.save()
```

Testing

The Stormpath Python SDK is well tested. Don't take our word on it though, run our test suite and see for yourself!

We currently test against Python 2.7, 3.3, 3.4 and PyPy.

Testing with tox

The simplest way is to run the test suite is to install tox. Tox automatically tests the code on multiple versions of Python by creating virtualenvs.

To get started, installed tox:

$ pip install tox

There is a tox.ini file in the root folder of Stormpath SDK. You can modify it to suit your needs, then run:

$ tox

To run the test suite.

Running a single environment (Python 2.7)

$ tox  -e py27

Running a single test in that environment:

$ tox  -e py27 -- -k test_name_of_the_test

Testing without tox

What is common in all tests is that our setup.py uses pytest to run tests and the tests themselves use HTTPretty with unittest. Python mock is also (sometimes) used, but in Python 3.3, mock became part of the unittest module so you don't have to install it if you're using Python 3.3. The tests make sure the correct module is used.

To install those dependencies manually, there is a testdep command that checks the Python version and installs required packages accordingly:

$ python setup.py testdep

To run tests:

$ python setup.py test

Live Testing

All of the above methods use mock and HTTPretty and don't query Stormpath. That makes them fast and self-reliant. If you want to run tests that don't patch any of the methods, you have to set the following environment variables to working Stormpath credentials:

$ export STORMPATH_API_KEY_ID=YOUR_APIKEY_ID
$ export STORMPATH_API_KEY_SECRET=YOUR_APIKEY_SECRET

To run the live tests against the Stormpath service, you can then run:

$ python setup.py livetest

WARNING: Since the tests make live changes to Stormpath data, DO NOT run these tests in a production environment!

Contributing

You can make your own contributions by forking the development branch of this repository, making your changes, and issuing pull requests on the development branch.

We regularly maintain our GitHub repostiory, and are quick about reviewing pull requests and accepting changes!

Building and Installing the Development Package

To build and install the development branch yourself, you can do the following:

$ git clone git@github.com:stormpath/stormpath-sdk-python.git
$ cd stormpath-sdk-python
$ python setup.py develop # If you want to install the package for development.

Documentation

To generate our Sphinx documentation, you'll need to first install sphinx:

$ pip install sphinx

Next, you'll want to run:

$ python setup.py docs

To build the HTML documentation. You can then open your browser and navigate to docs/_build/html/index.html, which should open the fully built HTML documentation!
