Detailed explanation of the food supplier management function in the Go language ordering system

With the rapid development of the Internet and the increasing demand for convenient and fast life, more and more people are More and more catering industries are beginning to adopt online ordering systems to provide better services and experiences. In these ordering systems, the food supplier management function is a very important part, which is directly related to the procurement of restaurant food and cooperation with suppliers.

This article will use Go language as a development tool to introduce in detail the design and implementation of the dish supplier management function in the ordering system, and provide relevant code examples.

1. Management of dish supplier information
   In the ordering system, the management of dish supplier information is essential. We can use a database (such as MySQL) to store and manage dish supplier information, including supplier name, contact person, contact information, address, etc. In Go language, you can use third-party ORM libraries (such as GORM) to simplify database operations. The following is a sample code:

// 定义供应商模型
type Supplier struct {
    gorm.Model
    Name        string
    Contact     string
    ContactInfo string
    Address     string
}

// 创建供应商
func CreateSupplier(name, contact, contactInfo, address string) (*Supplier, error) {
    supplier := &Supplier{
        Name:        name,
        Contact:     contact,
        ContactInfo: contactInfo,
        Address:     address,
    }
    if err := db.Create(supplier).Error; err != nil {
        return nil, err
    }
    return supplier, nil
}

// 根据ID获取供应商
func GetSupplierByID(id uint) (*Supplier, error) {
    supplier := &Supplier{}
    if err := db.First(supplier, id).Error; err != nil {
        return nil, err
    }
    return supplier, nil
}

2. Query and filtering of food suppliers
   In the ordering system, there may be a large number of food suppliers, so query and filtering are provided This function allows restaurant managers to quickly find the suppliers they need. The following is a query sample code based on the name of the dish supplier:

// 根据供应商名称查询供应商
func GetSupplierByName(name string) ([]*Supplier, error) {
    suppliers := []*Supplier{}
    if err := db.Where("name = ?", name).Find(&suppliers).Error; err != nil {
        return nil, err
    }
    return suppliers, nil
}

3. Update and deletion of the dish supplier
   The information of the dish supplier may occur over time changes, so corresponding update and delete functions need to be provided. The following is a sample code:

// 更新供应商信息
func UpdateSupplier(supplier *Supplier, name, contact, contactInfo, address string) error {
    supplier.Name = name
    supplier.Contact = contact
    supplier.ContactInfo = contactInfo
    supplier.Address = address
    if err := db.Save(supplier).Error; err != nil {
        return err
    }
    return nil
}

// 删除供应商
func DeleteSupplier(supplier *Supplier) error {
    if err := db.Delete(supplier).Error; err != nil {
        return err
    }
    return nil
}

Through the above sample code, we can implement a basic dish supplier management function, including adding, querying, updating and deleting supplier information.

Summary:
In the ordering system, the design and implementation of the dish supplier management function is very important for the daily operations of the restaurant. Through Go language development tools and related libraries, we can quickly implement this function and provide efficient supplier management services without affecting system performance. Through the introduction and sample code of this article, readers can have a basic understanding and conduct further development and optimization according to actual needs.
