#### `HeroBase` - the base class

Let's start with a `HeroBase` model that has all the **fields that are shared** by all the models:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### `Hero` - the *table model*

						columnType.Name(), length, 100, columnType)
				}
			case "age":
				if v, ok := columnType.DefaultValue(); !ok || v != "18" {
					t.Fatalf("column age default value should be correct, name: %v, column: %#v", columnType.Name(),
						columnType)
				}
				if v, ok := columnType.Comment(); !ok || v != "my age" {
					t.Fatalf("column age comment should be correct, name: %v, column: %#v", columnType.Name(),
						columnType)

     * Cache-Control: max-age=600
     * ```

     * A typical HTTPS file looks like this:
     *
     * ```
     * https://google.com/foo
     * GET
     * 2
     * Accept-Language: fr-CA
     * Accept-Charset: UTF-8
     * HTTP/1.1 200 OK
     * 3
     * Content-Type: image/png
     * Content-Length: 100
     * Cache-Control: max-age=600
     *
     * AES_256_WITH_MD5

Ahora que sabes que tienes que arreglarlo convierte `age` a un string con `str(age)`:
