## Update the App with Multiple Models { #update-the-app-with-multiple-models }

Now let's **refactor** this app a bit to increase **security** and **versatility**.

    assertEquals(0, stats.hitCount());
    assertThat(stats.hitRate()).isEqualTo(0.0);
    assertEquals(1, stats.missCount());
    assertThat(stats.missRate()).isEqualTo(1.0);
    assertEquals(1, stats.loadCount());
    long totalLoadTime = stats.totalLoadTime();
    assertTrue(totalLoadTime >= 0);
    assertTrue(stats.averageLoadPenalty() >= 0.0);
    assertEquals(0, stats.evictionCount());

    cache.getUnchecked(one);

     * @param timeout the timeout in milliseconds
     * @param leaseKey the associated lease key (can be null)
     * @return the handle GUID
     */
    public HandleGuid requestDurableHandle(String path, HandleType type, long timeout, Smb2LeaseKey leaseKey) {
        HandleGuid guid = new HandleGuid();

        // Create handle info with empty file ID (will be populated after successful create response)

There is a **special** environment variable called **`PATH`** that is used by the operating systems (Linux, macOS, Windows) to find programs to run.

The value of the variable `PATH` is a long string that is made of directories separated by a colon `:` on Linux and macOS, and by a semicolon `;` on Windows.

For example, the `PATH` environment variable could look like this:

//// tab | Linux, macOS

mc admin trace --all --verbose myminio
```

Ви не змогли б отримати таку підтримку в редакторі, якби працювали напряму зі  `dict`, а не з моделями Pydantic.
