Multi-layered permissions in Symfony

Question

I'm trying to implement a service which allows users to create "organizations" as subdomains. I want my users to allow inviting people to invite them to their "organization", e.g. orgname.exampleapp.com.

As I have a fair bit of familiarity with Symfony, I'd like to use it to build this project. I've read a fair bit of documentation on roles, groups, voters, etc. but I can't quite piece it together. Therefore my question:

How would I best approach building a permission system in Symfony 2.6+ matching this criteria:

• Users should register on a main page, e.g. example.com
• Users should be able to create organizations, which get assigned a subdomain (e.g. orgname.exampleapp.com)
• Users should be able to invite people to organizations.
• Users should be able to put people into groups for a specific organization.
• Users should be able to assign permissions to groups for a specific organization.

I have control over the servers I intend to run this on, so I am not opposed to constructs that use an SSO or require provisioning an own virtual machine / cloud server / etc.

Answer 1

Voters suits your requirements just fine. They're simple and allows to validate complex rules.

In my personal experience, it's about changing mindset from typical ACL approach. Saying that, I recommend you checking these slides with comparison of ACL and Voters, where it's nicely explained.
