Permissions can be inherited from other objects (pretty slick!)

As a Developer, I want to be able to implement access control policies that are inherited from another object so that I can easily propagate access control policies within my application.

If you want to set a default permission for objects in a collection that inherit permissions from another object, it is super easy using FFDL (what is FFDL?).


Say you have a Collection of JokeBook objects with permission defaults set and another Collection of Joke objects that have a reference to a JokeBook and you would like your Joke objects to inherit their default permissions from JokeBook objects. OK – short version is that I want the permissions for a Joke to be the same as the JokeBook they refer to.

The FFDL would look something like:

# JokeBook
CREATE OBJECTTYPE JokeBook (title STRING, writers REFERENCE /FFUserGroup, readers REFERENCE /FFUserGroup)

PERMIT read:object.readers write:object.writers ON /JokeBooks

This defines a JokeBooks Collection that contains Jokebook Objects that have a title, a reference to an author, a reference to a group of users with write access named writers and a group of users with read access named readers.

# Joke
CREATE OBJECTTYPE Joke (setup STRING, punchline STRING, book REFERENCE /JokeBook)


PERMIT read:object.book.readers write:object.book.writers ON /Jokes

This defines a Jokes Collection that contains Joke Objects which have a reference called “book” from the JokeBooks Collection:

book REFERENCE /JokeBooks

So, you will notice that read and write permissions for a Joke object are set to refer to the read and write permissions (respectively) that are defined for the JokeBook object referred to by the “book” member.

PERMIT read:object.book.readers, write:object.book.writers ON /Jokes

Voila! Now the Joke object has the same permissions as the JokeBook object – as easy as that!

Of course, this is the default setting and you can always change the access to any particular object programmatically in your application code.

Hope you find this useful!!

For more details, see the FFDL documentation here.

Why the name FatFractal?

People always ask us for the meaning behind the name “FatFractal”, so we decided to write a blog post about it!

We wondered, “why is it so difficult for developers, like us, to find a platform that makes it easy to create compelling apps with a cloud backend?”

The Backbone of FatFractal -

We could not find an end-to-end solution with everything we needed: native code support for any connected device, an events model, declarative security, custom code and all of those things integrated as lightweight services. Everything had to be elegant, easy-to-use, intuitive and delightful.

The underlying platform needed to be engine-based for dynamic scaling, to support any infrastructures, to have a published services model and to be able to support any languages, backend and frontend. We liked developing on local machines and insisted on deploying to the cloud without reconfiguration. And we wanted it all to be boilerplate free and reasonably priced.

Since we couldn’t find it, we built it - 

When we named the company FatFractal, we had in mind the intersection of the exploding mobile apps space, our technology platform and the cloud. The heart of our platform is a small, simple engine. Since all applications, modules, components and services on the platform have FatFractal engines at their core, some techie-types might call the resulting topology a fabric.

The reason behind the name -

The metaphor we like best is the fractal: the engines at the heart of services are self-similar, components that replicate and scale in a fractal-like pattern. As the fabric expands, emergent properties of the system can be both surprising and compelling. As apps, services, components, threads and IaaS’s are added in, that fractal-like fabric scales fast, getting as vast–or as compact–as it needs. We continue to believe that the cloud is more like a fractal than a…um…cloud.
Hence, the name: FatFractal

FatFractal Provides the Software To KickStart Your Idea. 

DevRev is the Community that Tells Your Story.


There are a number of barriers that prevent developers from getting going on developing apps. Frequently, this means that they need to find a backend engineer and/or a DevOps engineer to work with before they can even get started, and those resources are hard to find.

If you don’t already know, FatFractal is a company that is passionate about removing barriers that inhibit new startups from getting their ideas to market as fast as possible. By providing a public cloud platform, FatFractal helps you get your product working in record time.


The notion behind being able to build your product from just an idea and take it to market as fast as possible with the least amount of hurdles is something we strongly believe in.

Entrepreneurs, Innovators, and Idea Generators are all individuals who fall in that category. Idea Generators especially will relate to that category. Lots of people have ideas, not many actually do something about it.


They simply don’t know where to start –  

“I have a great idea! but no clue on what to do with it”. The thought process of turning an idea to a product can be daunting to certain individuals, especially when it exists outside of their field of knowledge.

They’re afraid of FAILURE -

The word “failure” above is in all-caps because thats how much people get intimidated by the idea of it. A common trend you will notice among successful people is that they are never afraid to fail. Valuable lessons can be learned from failure.

They don’t like the feeling of uncertainty -

This is different than fear of failure. It’s an aversive state that generally we try to escape from. Unfortunately creativity requires uncertainty by definition, because we’re trying to do something that hasn’t been done before.



DevRev is an open, online conversation with shared stories about the problems that entrepreneurs face as well as innovative solutions that others have created to solve them. If you are, or want to be an entrepreneur, then come share your story so that others can benefit from your experience and share their experiences with you.

We believe that entrepreneurs are the engine of the future more now than ever.
We are driven by a passion to accelerate the process of getting from an idea to market success faster and better. Everything we do is intended to identify barriers that inhibit innovation and create a community to smash them.

What we have created, is an online community to research the problem areas that get in the way of creating great things, and look for ways to radically improve them.
