Hi There,

Reply : In Odoo, there are mainly two types of controllers available:

1. HTTP Controllers: These controllers are used to handle HTTP requests and responses. HTTP controllers can be used to create custom web pages, handle form submissions, and provide RESTful web services. HTTP controllers are defined as Python classes that inherit from the "odoo.http.Controller" class.

2. Report Controllers: These controllers are used to generate reports in various formats, such as PDF, Excel, or CSV. Report controllers are defined as Python classes that inherit from the "odoo.report.report_controller" class.
