And now in the file `sql_app/main.py` let's integrate and use all the other parts we created before.

### Create the database tables

In a very simplistic way create the database tables:

```Python hl_lines="9-11"
{!../../../docs_src/sql_databases_peewee/sql_app/main.py!}
```

### Create a dependency

Create a dependency that will connect the database right at the beginning of a request and disconnect it at the end:

- Click the left sidebar "VCS Roots" here and create a VCS root [here](https://builds.gradle.org/admin/editProject.html?projectId=Gradle&cameFromUrl=%2Fproject.html%3FprojectId%3DGradle%26tab%3DprojectOverview%26branch_Gradle_Master_Check%3Dmaster)
  - Suppose the VCS root you just create is `MyNewVcsRoot`. Set "default branch" to `myTestBranch` where your code exists.

    /** Returns a new response body that transmits this byte array. */
    @JvmStatic
    @JvmName("create")
    fun ByteArray.toResponseBody(contentType: MediaType? = null): ResponseBody = commonToResponseBody(contentType)

    /** Returns a new response body that transmits this byte string. */
    @JvmStatic
    @JvmName("create")

    override fun getAnalysisSession(useSiteKtElement: KtElement): KtAnalysisSession {
        val facade = Fe10AnalysisFacade.getInstance(project)
        val token = tokenFactory.create(project, project.createProjectWideOutOfBlockModificationTracker())
        val context = facade.getAnalysisContext(useSiteKtElement, token)

      }
      if (project.file("Module.md").exists()) {
        includes.from(project.file("Module.md"))
      }
      externalDocumentationLink {
        url.set(URI.create("https://square.github.io/okio/3.x/okio/").toURL())
        packageListUrl.set(URI.create("https://square.github.io/okio/3.x/okio/okio/package-list").toURL())
      }
    }
  }

  plugins.withId("com.vanniktech.maven.publish.base") {

{!../../../docs_src/custom_response/tutorial007.py!}
```

#### Using `StreamingResponse` with file-like objects

If you have a file-like object (e.g. the object returned by `open()`), you can create a generator function to iterate over that file-like object.

That way, you don't have to read it all first in memory, and you can pass that generator function to the `StreamingResponse`, and return it.

    override val annotationsList: KtAnnotationsList
        get() = withValidityAssertion {
            descriptor?.let { KtFe10AnnotationsList.create(it.annotations, analysisContext) } ?: KtEmptyAnnotationsList(token)
        }

    @OptIn(KtAnalysisApiInternals::class)
    override fun createPointer(): KtSymbolPointer<KtPropertySetterSymbol> = withValidityAssertion {

  // See documentation for the "matchPolicy" field in the webhook configuration type.
  // +optional
  optional string requestSubResource = 15;

  // Name is the name of the object as presented in the request.  On a CREATE operation, the client may omit name and
  // rely on the server to generate the name.  If that is the case, this field will contain an empty string.
  // +optional
  optional string name = 5;

helm repo update
```

_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._

## Installing the Chart

To install the chart with the release name `istio-base`:

```console
kubectl create namespace istio-system
helm install istio-base istio/base -n istio-system
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.

    override val token: KtLifetimeToken
        get() = owningProperty.token

    override val annotationsList: KtAnnotationsList
        get() = withValidityAssertion {
            KtFe10AnnotationsList.create(descriptor?.annotations ?: Annotations.EMPTY, analysisContext)
        }
