### Das Problem reproduzieren

In den meisten Fällen und bei den meisten Fragen ist etwas mit dem von der Person erstellten **eigenen Quellcode** los.

In vielen Fällen wird nur ein Fragment des Codes gepostet, aber das reicht nicht aus, um **das Problem zu reproduzieren**.

func TestScanToEmbedded(t *testing.T) {
	person1 := Person{Name: "person 1"}
	person2 := Person{Name: "person 2"}
	DB.Save(&person1).Save(&person2)

	address1 := Address{Name: "address 1"}
	address2 := Address{Name: "address 2"}
	DB.Save(&address1).Save(&address2)

	DB.Create(&PersonAddress{PersonID: person1.ID, AddressID: int(address1.ID)})
	DB.Create(&PersonAddress{PersonID: person1.ID, AddressID: int(address2.ID)})

### Klassen als Typen

Sie können auch eine Klasse als Typ einer Variablen deklarieren.

Nehmen wir an, Sie haben eine Klasse `Person`, mit einem Namen:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

Dann können Sie eine Variable vom Typ `Person` deklarieren:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

### Классы как типы

Вы также можете объявить класс как тип переменной.

Допустим, у вас есть класс `Person` с полем `name`:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

Тогда вы можете объявить переменную типа `Person`:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

И снова вы получаете полную поддержку редактора:

* ...and others.

### Classes as types

You can also declare a class as the type of a variable.

Let's say you have a class `Person`, with a name:

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}

Then you can declare a variable to be of type `Person`:

{* ../../docs_src/python_types/tutorial010.py hl[6] *}

And then, again, you get all the editor support:

### Lớp như kiểu dữ liệu

Bạn cũng có thể khai báo một lớp như là kiểu dữ liệu của một biến.

Hãy nói rằng bạn muốn có một lớp `Person` với một tên:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

Sau đó bạn có thể khai báo một biến có kiểu là `Person`:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

func TestMultipleMany2Many(t *testing.T) {
	type Thing struct {
		ID int
	}

	type Person struct {
		ID       int
		Likes    []Thing `gorm:"many2many:likes"`
		Dislikes []Thing `gorm:"many2many:dislikes"`
	}

	checkStructRelation(t, &Person{},
		Relation{
			Name: "Likes", Type: schema.Many2Many, Schema: "Person", FieldSchema: "Thing",
			JoinTable: JoinTable{Name: "likes", Table: "likes"},

### ক্লাস হিসেবে টাইপস

আপনি একটি ভেরিয়েবলের টাইপ হিসেবে একটি ক্লাস ঘোষণা করতে পারেন।

ধরুন আপনার কাছে `Person` নামে একটি ক্লাস আছে, যার একটি নাম আছে:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

তারপর আপনি একটি ভেরিয়েবলকে `Person` টাইপের হিসেবে ঘোষণা করতে পারেন:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

### Classes como tipos

Você também pode declarar uma classe como o tipo de uma variável.

Digamos que você tenha uma classe `Person`, com um nome:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

Então você pode declarar que uma variável é do tipo `Person`:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```
