With SQLModel, we can use **inheritance** to **avoid duplicating** all the fields in all the cases.

#### `HeroBase` - the base class { #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] *}

    }

    /**
     * Returns whether all regular expressions must match for this rule to match.
     * @return true if all patterns must match, false if only one needs to match
     */
    public boolean isAllRequired() {
        return allRequired;
    }

    /**
     * Sets whether all regular expressions must match for this rule to match.
     * @param allRequired true if all patterns must match, false if only one needs to match

{* ../../docs_src/bigger_applications/app_an_py39/routers/users.py hl[6,11,16] title["app/routers/users.py"] *}

Sie können sich `APIRouter` als eine „Mini-`FastAPI`“-Klasse vorstellen.

Alle die gleichen Optionen werden unterstützt.

Alle die gleichen `parameters`, `responses`, `dependencies`, `tags`, usw.

/// tip | Tipp

In diesem Beispiel heißt die Variable `router`, aber Sie können ihr einen beliebigen Namen geben.

				cr := newReader(bytes.NewBuffer(in.input))
				all := dst[:0]
				err := func() error {
					// Read all records until EOF or another error.
					for {
						record, err := cr.Read()
						if err == io.EOF {
							return nil
						}
						if err != nil {
							return errCSVParsingError(err)
						}
						var recDst []string
						if len(dst) > len(all) {
							recDst = dst[len(all)]
						}

        createdTime = null;
        versionNo = null;

    }

    /**
     * Get the all record count.
     * @return The all record count.
     */
    public int getAllRecordCount() {

 utilizing the local installation, the group level allows configuration management for all the projects
 that belong to the same group, the project level allows configuration management at
 the project level, and the user level allows users to override settings on
 the site level, group level and project level.

* Site configuration

     * It should be the matcher returned by the other methods of this interface when the
     * given patterns match all files.
     *
     * @return path matcher that unconditionally returns {@code true} for all files
     */
    @Nonnull
    PathMatcher includesAll();

    /**
     * {@return whether the given matcher includes all files}.

Der Parameter `security_scopes` wird vom Typ `SecurityScopes` sein.

Dieses verfügt über ein Attribut `scopes` mit einer Liste, die alle von ihm selbst benötigten Scopes enthält und ferner alle Abhängigkeiten, die dieses als Unterabhängigkeit verwenden. Sprich, alle „Dependanten“ ... das mag verwirrend klingen, wird aber später noch einmal erklärt.
