Simple-Class-Tree

ASP.Net web app and API for creating and managing and querying a simple Class tree.

NOTES:

1. This project uses a remot SQL Server deployed on Azure.

2. Added a Root class with CID - 0 and PID = Null, because:

• System checks the new class' PID before saving,
• It has to match an existing CID,
• therefore, a Root was needed to have all first level classes as its children.

3. The default output of the api was application/xml: the class BrowserJsonFormatter.cs configures default output to application/json it is registered and added as a formatter in WebApiConfig.cs.

4. ClassController is for the web GUI functionality

5. CheditorClass is for the API functionality

TECHNOLOGIES & TECHNIQUES:

1. Remote JS/AJax (Client-side) model validation:

• Location: Models/GUIClassPartial
• Usage: input validation before submission
• Source: https://www.youtube.com/watch?v=Ll8VtDRj8L4&t=208s

2. Server-side model validation for posted Create() model

• location: Controllers/ClassController/Create() => POST
• Usage: Check CID!= PID, and check PID exists => in case client side JS is disabled.

3. Json formatter:

• Loocation: ~/BrowserJsonFormatter.cs at project main folder Register above class at App_Start/WebAPIConfig.cs
• Usage: formats all API output into JSON
• Source: Stackoverflow.com

4. Optional API Paramerters:

• Location: Controllers/cheditorController.cs/AddClass(int? cid, string name, bool Abstract, int? pid = null)
• Usage: value for pid can be neglected in the post method

5. Entity Framework

FUTURE WORK:

1. Optimise model validation for both controllers

2. Enable muliti classes addition using JSON

3. Manipulate JSON responses for API

4. Add a tree view for Index() in ClassController

5. Fix Name validation bug when trying to post to Edit().
