The Grails Framework 6.0.0

(Quick Reference) ## lazy ### Purpose Configures whether to use proxies and lazy loading for one-to-one and many-to-one associations. ### Examples
    class Book {

        static belongsTo = [author: Author]

        static mapping = {
            author lazy: false
        }
    }
### Description Usage: `association_name(lazy: boolean)` By default GORM single-ended associations are lazy in that when you load a domain instance, an associated domain is not loaded until accessed. Hibernate creates a dynamic proxy by subclassing the domain class and proxying all methods and property access. This can have some strange side effects (see this page on proxies at the Hibernate site) particularly in relation to inheritance. You can tell Hibernate not use proxies for single-ended associations by using the `lazy` argument:
    static mapping = {
        author lazy: false
    }
