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:

    /** 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")

  // field as a collision avoidance mechanism when it needs to create the name for the
  // newest ReplicaSet.
  // +optional
  optional int32 collisionCount = 8;
}

// DeploymentStrategy describes how to replace existing pods with new ones.
message DeploymentStrategy {
  // Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.
  // +optional
  optional string type = 1;

Let's say you want it to return indented and formatted JSON, so you want to use the orjson option `orjson.OPT_INDENT_2`.

You could create a `CustomORJSONResponse`. The main thing you have to do is create a `Response.render(content)` method that returns the content as `bytes`:

```Python hl_lines="9-14  17"
{!../../../docs_src/custom_response/tutorial009c.py!}
```

Now instead of returning:

        rootDir.withFile("version.txt", "1.0")

        val inputBuildDir = setupRunBinaryCompatibility(v1, v2)

        val runner = GradleRunner.create()
            .withProjectDir(inputBuildDir)
            .withPluginClasspath()
            .withArguments(":binary-compatibility:checkBinaryCompatibility", "-s")

        val (buildResult, failure) = try {

  // field as a collision avoidance mechanism when it needs to create the name for the
  // newest ReplicaSet.
  // +optional
  optional int32 collisionCount = 8;
}

// DeploymentStrategy describes how to replace existing pods with new ones.
message DeploymentStrategy {
  // Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.
  // +optional
  optional string type = 1;

    )

    /**

    fun headers(

```Python hl_lines="1"
async def get_burgers(number: int):
    # Do some asynchronous stuff to create the burgers
    return burgers
```

...instead of `def`:

```Python hl_lines="2"
# This is not asynchronous
def get_sequential_burgers(number: int):
    # Do some sequential stuff to create the burgers
    return burgers
```

   * need. Both fields are guarded by [lock].
