Product Management Application - Functionality Overview

This README file provides an overview of the functionality implemented in a product management application. The application allows users to manage products, categorize them, and perform various actions based on user roles. Below, each point of the specified functionality is explained separately:

1) Products Filteration by Current Time

• When the application loads, it retrieves and displays the products that are supposed to be shown at the current time.
• This functionality is available to all users, regardless of their role (admin or Anonymous users).
• The displayed products are dynamically filtered based on the current time, ensuring that only relevant products are shown.
• The filteration is performed automatically upon application load, without any explicit user action.

2) Product Information

• Each product in the application is associated with the following information:
  • Name: The name of the product.
  • Creation Date: The date when the product was created.
  • Created By User ID: The ID of the user who created the product.
  • Start Date: The date when the product becomes available.
  • Duration: The duration of the product's availability.
  • DurationType:that may be (day,hours,minutes).
  • Price: The price of the product.

3) Categorization of Products

• Each product can be assigned to one category.

4) Managing Products

• Adding, editing, and deleting products are actions that can be performed only by users with the "Admin" role.
• Non-admin users do not have access to these management functionalities.
• Admin users can perform the following actions on products:
  • Add a new product: Create and save a new product in the application.
  • Edit an existing product: Modify the information of an existing product.
  • Delete an existing product: Remove a product from the application.

Application Interfaces (Views)

The application provides several views that enable users to interact with the product management functionality. The following views are available:

• All Products View (Admins Only):

  • This view displays all products in the application, regardless of the current time.
  • Access to this view is restricted to users with the "Admin" role.
  • All products are shown, providing an overview of the product characteristics.

• Add/Edit/Delete Product Views (Admins Only) with require validations:

  • These views allow admin users to add new products, edit existing products, and delete products from the application.
  • Only users with the "Admin" role can access these views.

• Product Details View:

  • This view provides detailed information about a specific product. -admin can see all product characteristics.
  • Anonymous users can only see all product (name, category,Creation Date,price) .

• Category Filter (Client-side):

  • The application offers the ability to filter products by category.
  • This filter functionality is implemented on the client-side, allowing users to selectively display products belonging to a specific category.

Seeding Data to the Database

The application utilizes two approaches to seed data into the database.

• Seeding Categories using DbContext :

  • The categories data is seeded into the database using the DbContext class in by overrideing (OnModelCreating).
  • This approach ensures that the categories table is populated with the required initial data.
  • It allows the application to have predefined categories for product categorization.

• Seeding Default Users and Roles :

  • in Program File as an entry point of the application, to check if the default users and roles exist.
  • by using app service to get ServiceScopeFactory instance to fetsh require servidce from RoleManager and UserManager and provide them to the Seeding methods,
  • If the default users and roles are not found.
  • This approach ensures the presence of default users and roles.
