FastAPI includes an extremely easy to use, but extremely powerful <abbr title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> system.

* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.
* All the dependencies can require data from requests and **augment the path operation** constraints and automatic documentation.

				o.ID = c.id
				go c.keepAlive(ctx, rpc)

	}

	if o.ID != "" && !o.Transient {
		// We have an existing list ID, continue streaming.
		if o.Create {
			o.debugln("Creating", o)
			entries, err = z.listAndSave(ctx, o)
			if err == nil || err == io.EOF {
				return entries, err

			entries.truncate(0)

Make sure you use a supported label from the <a href="https://github.com/tiangolo/latest-changes#using-labels" class="external-link" target="_blank">latest-changes list of labels</a>:

* `breaking`: Breaking Changes
    * Existing code will break if they update the version without changing their code. This rarely happens, so this label is not frequently used.
* `security`: Security Fixes

   * deterministic iteration behavior.
   *
   * <p>This method is just a small convenience, either for {@code newHashSet(}{@link Arrays#asList
   * asList}{@code (...))}, or for creating an empty set then calling {@link Collections#addAll}.
   * This method is not actually very useful and will likely be deprecated in the future.

You can use the same type declarations with `str`, `float`, `bool` and many other complex data types.

Several of these are explored in the next chapters of the tutorial.

## Order matters { #order-matters }

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

-   x86 and arm64
-   CPU-only, or with NVIDIA CUDA support (Linux only), or with TPUs

## How to Test Your Changes to TensorFlow

You may check how your changes will affect TensorFlow by:

1. Creating a PR and observing the presubmit test results
2. Running the CI scripts locally, as explained below
3. **Google employees only**: Google employees can use an internal-only tool

	DB.Table("langs").Migrator().DropTable(&Language{})
	DB.Table("langs").AutoMigrate(&Language{})

	if err := DB.Table("langs").Save(&lang).Error; err != nil {
		t.Errorf("no error should happen when creating data, but got %v", err)
	}

	var result3 Language
	if err := DB.Table("langs").First(&result3, "code = ?", lang.Code).Error; err != nil || result3.Name != lang.Name {
