Yes it’s possible however your function should return interface{}
and not []*interface
.
func (c Helper) ReturnModels(modelName string) interface{} {}
In this case you could use Type Switches and/or Type Assertions to cast the return value into it’s original type.
Example
Note: I’ve never used Revel, but the following snippet should give you an a general idea:
Playground
package main
import "fmt"
type Post struct {
Author string
Content string
}
type Brand struct {
Name string
}
var database map[string]interface{}
func init() {
database = make(map[string]interface{})
brands := make([]Brand, 2)
brands[0] = Brand{Name: "Gucci"}
brands[1] = Brand{Name: "LV"}
database["brands"] = brands
posts := make([]Post, 1)
posts[0] = Post{Author: "J.K.R", Content: "Whatever"}
database["posts"] = posts
}
func main() {
fmt.Println("List of Brands: ")
if brands, ok := ReturnModels("brands").([]Brand); ok {
fmt.Printf("%v", brands)
}
fmt.Println("\nList of Posts: ")
if posts, ok := ReturnModels("posts").([]Post); ok {
fmt.Printf("%v", posts)
}
}
func ReturnModels(modelName string) interface{} {
return database[modelName]
}
