Gizmo is a library that allows for the creation of versioned, view-aware objects written in a relational style. It is a simple, safe, and productive framework for creating content that will be present data different in different situations and is automatically versioned on every change.

1. Download and install it:

   $ go get github.com/FoxComm/gizmo

2. Run the database migrations:

   $ gizmo setup

3. Import gizmo to your code:

   import "github.com/FoxComm/gizmo"

4. Add gizmo.EntityObject to the struct you want to save:

   type Product struct {
     gizmo.EntityObject
   
     Title       string
     Description string
   }

5. Create Manager and connect to your database:

   dbHost := "127.0.0.1"
   dbName := "gizmo"
   dbUser := "gizmo"
   dbPassword := "I<3Gizmo"
   
   mgr, err := gizmo.NewManager(dbHost, dbName, dbUser, dbPassword)

6. Save a struct implementing EntityObject using Manager:

   p := Product{
     Title:       "Some product",
     Description: "A product for demo purposes",
   }
   
   viewID := 1
   saved, err := mgr.Create(p, viewID)

7. Retrieve the struct based on it's ID and view ID:

   id := 1
   viewID := 1
   
   product := Product{}
   err := mgr.FindByID(id, viewID, &product)
