Providing the ability to delete list items offers several advantages:

  • Curation: Users can keep their lists focused on the movies they are currently interested in.
  • Organization: Removing unwanted movies helps maintain a clean and organized list.
  • Improved User Experience: The ability to delete items enhances the overall user experience by giving users more control over their lists.

Implementing Item Priority Updates

Adjusting the priority of items within a list is a powerful way for users to organize their movies according to their preferences. This feature allows users to highlight their favorite movies or arrange them in a specific order. Let's examine the technical and user interface aspects of this functionality.

Technical Implementation

The implementation of item priority updates required modifications in the service layer, data access layer, and the controller.

  1. MemberMovieListServiceManager: A new method was added to the MemberMovieListServiceManager to handle the updating of item priorities. This method takes the list item ID and the new priority as input, validates the input, and updates the priority in the database.
  2. Data Validation: The service manager validates that the new priority value is within an acceptable range and that the user has the necessary permissions to update the item's priority.
  3. Database Updates: The service manager interacts with the data access layer to update the item priority in the database. This typically involves executing an SQL UPDATE statement on the MemberMovieListItem table, modifying the Priority field.
  4. MemberMovieListController: A new endpoint was added to the MemberMovieListController to expose the item priority update functionality to the user interface.
