I wanted to overrid:


so I copied it to:


But the override is not working.

Please let me know how I can override it without creating a new module.

Thank you!


This won't work. I can't imagine any way to do it without the custom module, there are several clean ways, though, depending what you exactly want. Most wanted is using plugin pattern: Plugins docs

Another manner is using observer pattern if the feature you want to rewrite dispatches some events. More: Observer docs

Finally, if neither plugins nor observers suits your case you can use preference, which helps you to replace whole class. More: Preference tutorial

  • Thank you. You are right, cannot be done without custom module. I created custom module and used "preferences" method.
