API Usage

The py-fortress-sample project includes python module you can use as a starting point.

Prepare your python module for usage by importing:

from pyfortress import (
    # model
    User,
    Role,
    Perm,
    PermObj,
    # apis:
    review_mgr, 
    admin_mgr, 
    access_mgr,
    #exception handling:
    FortressError,
    global_ids
)

Add a user:

def test_add_user(self):
    """
    Add a basic user
    """
    print('test_add_user')
    
    try:
        admin_mgr.add_user(User(uid='foo1', password='secret'))
        print('test_add_user success')                        
    except FortressError as e:
        self.fail('test_add_user failed, exception=' + e.msg)

Add a role:

def test_add_role(self):
    """
    Add a basic role
    """
    print('test_add_role')        
    try:
        admin_mgr.add_role(Role(name='Customer'))
        print('test_add_role success')                        
    except FortressError as e:
        self.fail('test_add_role failed, exception=' + e.msg)

Add an object:

def test_add_obj(self):
    """
    Add a basic perm object
    """
    print('test_add_obj')
    
    try:
        admin_mgr.add_object(PermObj(obj_name='ShoppingCart'))
        print('test_add_obj success')                        
    except FortressError as e:
        self.fail('test_add_obj failed, exception=' + e.msg)

Add a perm:

def test_add_perm(self):
    """
    Add a basic perm
    """
    print('test_add_perm')
    
    try:
        admin_mgr.add_perm(Perm(obj_name='ShoppingCart', op_name='add'))
        print('test_add_perm success')                        
    except FortressError as e:
        self.fail('test_add_perm failed, exception=' + e.msg)

Assign a user:

def test_assign_user(self):
    """
    Assign a user to a role
    """
    print('test_assign_user')
    
    try:
        admin_mgr.assign(User(uid='foo1'), Role(name='Customer'))
        print('test_assign_user success')                        
    except FortressError as e:
        self.fail('test_assign_user failed, exception=' + e.msg)

Grant a permission:

def test_grant_perm(self):
    """
    Grant a permission to a role
    """
    print('test_grant_perm')
    
    try:
        admin_mgr.grant(Perm(obj_name='ShoppingCart', op_name='add'), Role(name="Customer"))
        print('test_grant_perm success')                        
    except FortressError as e:
        self.fail('test_grant_perm failed, exception=' + e.msg)

Now test signing on the RBAC way:

def test_create_session(self):
    """
    create session
    """
    print('test_create_session')
    
    try:
        session = access_mgr.create_session(User(uid='foo1', password='secret'), False)
        if not session:
            print('test_create_session fail')
            self.fail('test_create_session fail')
        else:
            print('test_create_session pass')
            pass                        
    except FortressError as e:
        self.fail('test_create_session failed, exception=' + e.msg)

The session will then be held on to by the client for subsequent calls like check_access and session_perms

Here’s how to check a single permission:

def test_check_access(self):
    """
    create session and check perm
    """
    print('test_check_access')
    
    try:
        session = ... obtained earlier
        result = access_mgr.check_access(session, Perm(obj_name='ShoppingCart', op_name='add'))
        if not result:
            print('test_check_access fail')
            self.fail('test_check_access fail')
        else:
            print('test_check_access pass')
            pass                        
    except FortressError as e:
        self.fail('test_check_access failed, exception=' + e.msg)

Retrieve all of the permissions as a list:

def test_session_perms(self):
    """
    create session and get perms for user
    """
    print('test_check_access')
    
    try:
        session = ... obtained earlier
        perms = access_mgr.session_perms(session)
        if not perms:
            print('test_session_perms failed')
            self.fail('test_session_perms failed')
        
        for perm in perms:
            print_perm(perm, 'session_perms: ')
        pass                        
    except FortressError as e:
        self.fail('test_session_perms failed, exception=' + e.msg)

There’s a bit more to standards-based RBAC than just these 10 apis, stay tuned…!

Does anybody know of a way that I can find out the names of the people in this amazing picture?

I recognize some of the most obvious ones: Jesse Jackson, Andrew Young, Coretta Scott King and her children, Ralph Abernathy, John Lewis (?), Julian Bond (?), but I'm sure that somewhere, there must be a copy of this picture with everyone tagged? I'd love to know more about the picture, and more about the people in it, besides those who are of course well-known to us all. The best I found was this, which is fascinating but I was hoping for even more.

Meanwhile, in other completely unrelated, but interesting to me, news:

It was just as big a storm as predicted: Record April Rains Raise Rivers And Flood Concerns
Yosemite National Park closed campgrounds and lodging in its busy Yosemite Valley because of flooding concerns, with the Merced River there expected to peak 5 feet (1.5 meters) above flood stage on Saturday.
...
Bodega Bay in the county received nearly 6 inches (15.2 centimeters) of rain for the day
...
Lake Oroville has been filling up all winter, and more water was coming in than flowing out Friday. The water level Friday night had topped 793 feet (242 meters). If it reaches about 830 feet (253 meters), water managers said they may open the gates to the spillway.
...
California officials say they hope to avoid using the main spillway but are confident it can safely function.
Test Drilling Launched at the Sinking Millennium Tower
Crews have quietly launched a $9 million exploratory drilling project at the Millennium Tower to evaluate a planned fix for the sinking and tilting structure, NBC Bay Area has learned.
The project started earlier this month on Beale Street and involves drilling holes between 200 and 300 feet down to bedrock. The goal is to see whether the method will stabilize the troubled foundation.
...
The so-called micropile strategy is not new; it was used to shore up the Mandalay Bay Resort in Las Vegas, which sank some 18 inches during construction before being stabilized by more than 500 micropiles.
Micropile Underpinning of the Mandalay Bay Hotel & Casino
The approach was to drill and install micropiles through holes cored into the mat and not bonded in the mat, so that the piles could be jacked into the ground and maintain the building at a desired level. Then structural beam supports would be installed to act as permanent attachments and jacking frames. The entire system had the capacity to lift the center of the tower if that proved to be necessary. In order to support the center core, a layout consisting of 536 micropiles (Pin Piles) was developed by the structural engineer, Lochsa Engineering. Due to the limited plan area and the fact that it would be impractical to delay elevator construction to drill inside the shafts, all piles were located outside of the shafts. The resulting system was designed to support the core as if it was one very large pile cap. All the micropiles used to support the hotel core were 200 feet deep, were fully bonded with grout to the various soil and caliche layers and were isolated from the mat. The decision to drill 200 feet was based on a fairly substantial caliche layer being encounter at the depth in a preliminary methods hole and subsequent boring also often encountering a similar layer.
FORM S-4 REGISTRATION STATEMENT
On February 2, 2018, Mr. Somorjai sent an email to Mr. Schott requesting a meeting to discuss various commercial matters, including joint business development ideas.
...
On February 26, 2018, Mr. Schott met with Mr. Benioff. During the course of this meeting, Mr. Benioff described the importance of an integration platform to Salesforce’s strategic plans, and observed that MuleSoft’s products could be the foundation of Salesforce’s integration platform. Mr. Benioff asked Mr. Schott if the MuleSoft board of directors would be open to the possibility of considering a combination of the two companies. Mr. Schott responded that, although MuleSoft was not for sale, the MuleSoft board of directors would consider in good faith any reasonable offer it received from Salesforce.

Between the afternoon of March 18, 2018 and the morning of March 20, 2018, representatives of WSGR continued to negotiate and finalized the draft definitive merger agreement with representatives of Wachtell Lipton.
SPRING EDITION: March 2018
Ridership on WETA’s San Francisco Bay Ferry has increased by 94 percent since 2012 to more than 2.7 million riders annually. The demand for ferry service has grown across all four service routes
...
WETA has already been modernizing and expanding its fleet, investing in infrastructure improvements, and planning for new service:
- Two of four new 400-passenger, 27-knot vessels have already entered service, with the third entering service in May and the fourth in December.
- Three new 445-passenger, 34-knot vessels for the Vallejo/North Bay services are expected in late 2018 and 2019.
- The North Bay Operations and Maintenance Facility in Vallejo opened in 2016, and the Ron Cowan Central Bay Operations and Maintenance Facility in Alameda is scheduled to open in Summer 2018.
- A major expansion of ferry landing facilities at the San Francisco Ferry Building is currently under construction with two gates scheduled to open in November.
- A Richmond ferry terminal is under construction and new service from Richmond to San Francisco is scheduled to start in Fall 2018.
Alameda’s Ferry Nightmare
The city downsized parking for the ferry terminal after area neighbors complained. “We protect our property values and make sure that this is a safe place for residents and homeowners,” said Dawn Jaeger, executive director of the Harbor Bay Isle Association.
Under the city’s new rules, four homeowners associations received parking permits for residents of the area. Ferry commuters aren’t allowed access to the permits.
The city’s decision on ferry parking comes as the Harbor Bay ferry has been experiencing a surge in popularity. The ferry’s ridership has surged by 68 percent in the past five years, according to a city report last fall.
Raising the Speed Limit on Future Growth
The final and perhaps most critical issue I want to highlight also relates to skills: We’re not adequately preparing a large fraction of our young people for the jobs of the future. Like in most advanced economies, job creation in the United States is being tilted toward jobs that require a college degree (OECD 2017). Even if high school-educated workers can find jobs today, their future job security is in jeopardy. Indeed by 2020, for the first time in our history, more jobs will require a bachelor’s degree than a high school diploma (Carnevale, Smith, and Strohl 2013).
These statistics contrast with the trends for college completion. Although the share of young people with four-year college degrees is rising, in 2016 only 37% of 25- to 29-year-olds had a college diploma (Snyder, de Brey, and Dillow 2018). This falls short of the progress in many of our international competitors (OECD 2018), but also means that many of our young people are underprepared for the jobs in our economy.
