How to use Go language to write the dish inventory management module in the door-to-door cooking system?

With the rise of takeout and home cooking, more and more people choose to enjoy delicious food at home. As a platform that provides door-to-door cooking services, food inventory management is an integral part. In this article, we will introduce how to use Go language to write the dish inventory management module in the door-to-door cooking system, and provide specific code examples.

The functions of the dish inventory management module mainly include adding, querying, modifying and deleting dishes. First, we need to define a dish structure.

type Dish struct {
    ID       int
    Name     string
    Quantity int
}

Next, we can use slicing to save the dish information.

var dishes []Dish

The function to add dishes is as follows:

func addDish(name string, quantity int) {
    dish := Dish{
        ID:       len(dishes) + 1,
        Name:     name,
        Quantity: quantity,
    }
    dishes = append(dishes, dish)
}

The function to query dishes is as follows:

func getDishByID(id int) *Dish {
    for i := range dishes {
        if dishes[i].ID == id {
            return &dishes[i]
        }
    }
    return nil
}

The function to modify dishes is as follows:

func updateDishQuantity(id, quantity int) {
    dish := getDishByID(id)
    if dish != nil {
        dish.Quantity = quantity
    }
}

The function to delete dishes is as follows:

func deleteDish(id int) {
    for i := range dishes {
        if dishes[i].ID == id {
            dishes = append(dishes[:i], dishes[i+1:]...)
            break
        }
    }
}

The above is the main code example of the dish inventory management module. In actual use, more functions can be added as needed.

In addition to basic dish inventory management, we can also implement some additional functions, such as inventory warnings and inventory statistics.

For inventory warning, you can add some judgment logic to the function of adding or modifying dishes, and send a notification to the administrator.

For inventory statistics, you can write a function to calculate the total quantity of all dishes and return the statistical results.

func calculateTotalQuantity() int {
    var totalQuantity int
    for i := range dishes {
        totalQuantity += dishes[i].Quantity
    }
    return totalQuantity
}

The above is a detailed introduction and code example on how to use Go language to write the dish inventory management module in the door-to-door cooking system. By using slices and structures of the Go language, we can quickly implement a fully functional dish inventory management module to provide users with a convenient and fast dish management experience. Both practitioners and users can manage and query the inventory of dishes through this module. I hope this article will be helpful to developers who are learning the Go language.
