Extending core classes via plugins

Added by Deleted user about 2 years ago

Hello,

is it possible to extend the core classes in plugins? Let's say that I want to add new class and I want to create many-to-many relationship between the new class and work packages (hence I would like to add new attribute to the work package to utilize has_many, through ). Is this possible to do in plugin or do I have to change the core functionality?

Have a nice day
