Install

bash
togo install togo-framework/model-behaviors

The togo equivalent of Rails acts_as_* / friendly_id / django-mptt — small, pure-Go, dependency-free building blocks you embed or call directly.

Behaviors

Timestamps

go
type Post struct { modelbehaviors.Timestamps; Title string }
p.Touch() // sets CreatedAt once, UpdatedAt every time

SoftDeletes

go
type Post struct { modelbehaviors.SoftDeletes }
p.Delete(); p.IsTrashed() // true
p.Restore()

Slugs

go
modelbehaviors.Slugify("Héllo, Wörld!")     // "hello-world"  (ASCII-folds accents)
slug := modelbehaviors.UniqueSlug("Post", func(s string) bool {
    return db.SlugExists(s)                  // appends -2, -3, … until free
})

Tags

go
tags := modelbehaviors.NewTagIndex()
tags.Tag("post-1", "go", "web")
tags.TaggedWith("go")   // ["post-1", …]
tags.TagsOf("post-1")   // ["go", "web"]
tags.Untag("post-1", "web")

Sortable (positions)

go
order := modelbehaviors.NewSortable("a", "b", "c")
order.MoveUp("c"); order.Reorder([]string{"b","a"})
order.Position("b"); order.Ordered()

Tree (generic adjacency)

go
tr := modelbehaviors.NewTree[string]()
tr.AddChild("root", "a"); tr.AddChild("a", "a1")
tr.Ancestors("a1")   // ["a", "root"]
tr.Descendants("root")
tr.Depth("a1")       // 1
tr.Path("a1")        // ["root", "a", "a1"]
