Ruby on Rails Developers

REQUIREMENTS

You need to design a programming module PERMISSIONS that would allow Caller to

Grant a permission to a user

Check if a user has a particular permission

Caller is an external system that uses our module (particularly it calls our API).

Permission is a user right to take an action or access a resource. Permissions for resource access can be READ or WRITE. For example, Caller can grant a permission ”reboot the server” (an example of action) OR write to a file “C:/[login to view URL]” (an example of resource) to a user Andrew.

Caller can grant permissions directly to a user OR via roles. If Caller wants to grant permissions via roles then Caller needs to register a role, grant permissions to the role and then assign the role to a user.

Caller can assign many roles to a user.

As a note, our module (you are designing) doesn’t provide any dictionaries to Caller. All objects (including Users) are created / managed by Caller. Our module provides ONLY functionality.

OUTCOME

NOTE: You don’t have to strictly use a specific programming language for the exercise. You can use just a meta syntax that would give us an idea of your solution - we’re not going to compile it for sure :).

We would expect you to write module API (a list of functions with parameters) and design a database for the module. A list of functions can look like this:

function AddEmployee(company, first_name, last_name, age): boolean;

function AddJob(company, first_name, last_name, age): boolean;

function IsEmployeeFired(employeeId): boolean;

...

If you want to pass an object as a parameter you can describe an object separately:

Class Company {

String name;

String address;

Integer taxId;

}

Database design can be presented as a list of tables with most important fields (no need to define indexes, etc). For example,

Table Companies {

Id,

Name,

Address,

TaxId

}

Table Employees {

Id,

CompanyId, // this is a foreign key to Company

FirstName,

LastName,

Job

}

Please apply If you can do this in shor time.
