## Toy Setups

Capacity constrained environments, MinIO will work but not recommended for production.

func RunMigrations() {
	var err error
	allModels := []interface{}{&User{}, &Account{}, &Pet{}, &Company{}, &Toy{}, &Language{}, &Coupon{}, &CouponProduct{}, &Order{}, &Parent{}, &Child{}, &Tools{}}
	rand.Seed(time.Now().UnixNano())
	rand.Shuffle(len(allModels), func(i, j int) { allModels[i], allModels[j] = allModels[j], allModels[i] })

			t.Fatalf("errors happened when update: %v", err)

		var user2 User
		DB.Preload("Toys").Find(&user2, "id = ?", user.ID)

The command deploys MinIO on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.

### Installing the Chart (toy-setup)

Minimal toy setup for testing purposes can be deployed using:

```bash

	if err := DB.Create(user).Error; err != nil {
		t.Fatalf("failed to create user, got error %v", err)
	}

	if err := DB.Select(clause.Associations, "Pets.Toy").Delete(&user).Error; err != nil {
		t.Fatalf("failed to delete user, got error %v", err)
	}

```json
{
    "reason": <string>
}
```

The reason message is returned to the client.

## Example Plugin Implementation

Let's see how to make use of a custom `Request` subclass to decompress gzip requests.

And an `APIRoute` subclass to use that custom request class.

### Create a custom `GzipRequest` class

/// tip

This is a toy example to demonstrate how it works, if you need Gzip support, you can use the provided [`GzipMiddleware`](../advanced/middleware.md#gzipmiddleware){.internal-link target=_blank}.
