How to add a custom method to *gorm.DB?

[Mrbeyond]

How can I add a custom chainable method to *gorm.DB: I want to add Paginate() method to the *gorm.DB instance and it shoulbe be chainable to other methods.

For example I want something like this:

db.Where("").Paginate(10) // where Paginate() is a custom method added to the db instance

Please I need this to avoid manually adding pagination logic to every part of the code where it is needed.
