Nested structure

[Денис Мухортов]

Hello everyone, there is a small problem how to get the total price field from the Order structure?

type Order struct {

    OrderUID          string  `json:"order_uid"`

    Entry             string  `json:"entry"`

    InternalSignature string  `json:"internal_signature"`

    Payment           Payment `json:"payment"`

    Items             []Items `json:"items"`

    Locale            string  `json:"locale"`

    CustomerID        string  `json:"customer_id"`

    TrackNumber       string  `json:"track_number"`

    DeliveryService   string  `json:"delivery_service"`

    Shardkey          string  `json:"shardkey"`

    SmID              int     `json:"sm_id"`

}

type Items struct {

    ChrtID     int    `json:"chrt_id"`

    Price      int    `json:"price"`

    Rid        string `json:"rid"`

    Name       string `json:"name"`

    Sale       int    `json:"sale"`

    Size       string `json:"size"`

    TotalPrice int    `json:"total_price"`

    NmID       int    `json:"nm_id"`

    Brand      string `json:"brand"`

}

Haven't seen yet that the type of nested structure is a slice

You can't get a *value* out of a *type*.  However if you have a *variable* of type Order, e.g.

var o Order

then you could do for example: o.Items[0].TotalPrice to get the TotalPrice of the first item.

Note: it would be conventional to have "type Item" rather than "type Items", because this type represents a single item.  That is, it would be clearer as:

type Order struct {

    ...

    Items  []Item

    ...

}

type Item struct {

    ...

}
