How to override the DomainClass.list() in GORM (Gr

问题:

People, I'm facing a problem with grails GORM, my Application is totally dependent of the DomainClass.list() method, it is in all of my create/edit GSPs, but now I need a particular behavior for listing objects. Being more specific I need to filter these lists (All of them) by one attribute.

The problem is I'm hoping not to change all the appearances of these methods calling, so is there a way to customize the behavior of the default list() method ? I need it to function just the way it does, but adding an ending filter.

Maybe you can use hibernate filter plugin (see here). This will allow you to filter all finder methods (including list()) based on a property:

static hibernateFilters = {
    enabledFilter(condition: 'deleted=0', default: true)
}

Have you considered using names queries? You could always do something like this:

class DomainClass {
    // ... class members

    static namedQueries = {
        myList { params->
            // put your complicated logic here
        }
    }
}

Then you can just replace your calls to DomainClass.list() with DomainClass.myList.list().
