Django website login/registration (+social logins) with custom user profile and permissions

I must start by saying that I am a developer myself, and have developed django apps before (so we can have a detailed technical discussion, if necessary). I am writing a django application which requires some features that I don't have the time to develop myself at the moment. The required functionality for the new application is given below. The project involves developing a minimal django application, that has the functionality listed below, using the provided templates: 1. Allows a user to register/login using: a). username, email, password b). social app: (fb, twitter, linkedIN, Google+) should be ALL be supported c). lost password retrieval Note: login must be made robust from attacks by limiting login attempts and throttling login attempts. 2. Custom home page and error page 3. Create custom permissions enforced by hierarchical membership (which expire on an expiry date) - and also to provide a set of functions that allow CRUD operations on this custom permissioning. 4. Create a custom userprofile which has membership information - so user object can be queried based on membership information, in the view layer and in routing logic etc. The API below explains this custom permissioning functionality further - and I'm available to answer any questions. API: create_user_membership(user_id, membership_id, start_date, end_date) update_membership(membership_id, start_date, end_date) revoke_membership(membership_id) Below, is pseudocode describing a draft object model for the custom permissioning: Membership: name # bronze, silver, gold, platinum description heirarchy_level # strictly positive integer UserMembership: user_id # FK to UserProfile membership_id # FK to Membership start_date finish_date UserProfile is_valid_member_of() # user's membership of specified membership name, exists and has not expired membership_is_gte() # user's membership exists and has not expired, and membership has rank <= specified membership name get_membership_info() # returns user membership object (or dict) TESTS ======== 1. New user can register using username/email/password 2. New user can register using social login (fb) 3. New user can register using social login (twitter) 4. New user can register using social login (LinkedIn) 5. New user can register using social login (Google) 6. User registered with any of the methods above (1-5), can login using the appropriate auth method, and be directed to the homepage 7. Test robustness against incorrect login attempts (number limit and throttling) 8. Invalid urls should display the custom error page 9. Custom Permission testing i). Create memberships via Admin Manager ii). Programmatically CRUD user memberships iii). Create a view that allows user membership testing logic to be used to restrict view display, depending on user membership. Note: Please note that the error404 page displays BREADCRUMBS. The implementation must show how to dynamically generate breadcrumbs on a page. LAST BUT NOT THE LEAST, I expect you to use pip for installing the required apps etc, and that the completed project will have a [login to view URL] file, so that I can replicate the environment on my development machine. ALSO - MAKE SURE YOU FULLY COMMENT THE CODE - SO I CAN UNDERSTAND IT AND EXTEND IT LATER.!!!
