Is it possible to eliminate my duplicated code and make it work on multiple model types?

Suppose I have two models Cat and Dog and both of them have a Name string field.

I am wondering if there is a way I can write a function in my own code that allows me to pass in either a Cat or a Dog instance (or a pointer to such an instance) and access the Name field within whatever was passed in.

I thought that it might be possible to do this if there was a way that the generated model code provided accessor methods for the fields like

func (c Cat) GetName() string {
	return c.Name
}

or maybe

func (c *Cat) GetName() string {
        if c == nil {
          return ""
        }
	return c.Name
}

If similar methods were generated for the Dog type, then I could create an interface like

type HasName interface {
    GetName() string
}

that was implemented by both of my model types, and then I could make a function like

func doStuff(n HasName) {
    fmt.Printf("Hello I have name %s!\n", n.GetName())
}

I am not sure that this approach is correct or that it is possible using the current model generation but I don't see it as being available. Instead I have to write two pretty-nearly identical funcs, one that operates on each type:

func doCatStuff(c models.Cat) {
    fmt.Printf("Hello I have name %s!\n", c.Name)
}

func doDogStuff(d models.Dog) {
    fmt.Printf("Hello I have name %s!\n", d.Name)
}

Is there a way around this code duplication?

Thank you for your help. I am still getting my feet wet with SQLBoiler and it is quite possible that I am missing something.

You could pass custom templates to SQLBoiler to generate these, but there is little documentation on how to write SQLBoiler templates.

I see, thank you. Perhaps if I have time later I will make an effort to do that. If I am able to make headway, perhaps I will make some notes, and those could be the seeds for some docs on templates.

Thank you.
