The "github.com.jinzhu.gorm" package library is a popular object-relational mapping (ORM) library for Go programming language. It simplifies working with databases by providing a high-level, expressive API for handling database operations.
One of the key features of GORM is the ability to save data to a database with ease. The Save() method is used to create or update a record in the database. If a new record is being created, GORM will automatically assign a primary key value and insert the record into the database. If an existing record is being updated, GORM will update the corresponding record in the database.
Here are some code examples demonstrating how to use the Save() function in GORM:
// Struct representing a user record type User struct { ID uint `gorm:"primary_key"` Name string Email string }
// Create a new user user := User{Name: "John Doe", Email: "[email protected]"} db.Save(&user)
// Update an existing user user.Name = "Jane Doe" db.Save(&user)
In the first example, a new user record is created with a name and email address, and then saved to the database using the Save() method. In the second example, an existing user record is retrieved from the database, updated with a new name, and then saved back to the database.
In both cases, the Save() method takes a pointer to the struct representing the record being saved. This allows GORM to automatically infer the type of the record and handle the database interactions accordingly.
Overall, the "github.com.jinzhu.gorm" package library is a powerful tool for working with databases in Go, and its Save() function makes it easy to persist data in a reliable and efficient manner.
