GORM Boolean Struct

GORM is a powerful ORM for the Go programming language. It provides a lot of features and functionalities that makes working with databases much easier for developers. One of these functionalities is the support for boolean struct fields.

Basic Usage

GORM allows you to define boolean fields in your struct tags using the bool data type. Here's an example:

type User struct {
    ID        uint   `gorm:"primary_key"`
    Name      string `gorm:"not null"`
    IsAdmin   bool   `gorm:"default:false"`
}

In this example, IsAdmin is a boolean field which has a default value of false. This means that if we create a new user without specifying the value of IsAdmin, it will default to false.

user := User{Name: "John Doe"}
db.Create(&user)

Querying Boolean Fields

When querying boolean fields in GORM, you can use comparison operators such as eq and neq to filter the results. Here's an example:

var isAdminUsers []User
db.Where("is_admin = ?", true).Find(&isAdminUsers)

var nonAdminUsers []User
db.Where("is_admin = ?", false).Find(&nonAdminUsers)

In this example, we are querying for users based on their IsAdmin field. The first query returns all users that have IsAdmin set to true, while the second query returns all users that have IsAdmin set to false.

Conclusion

GORM's support for boolean struct fields makes it easier for developers to work with databases. By defining boolean fields in your struct tags, you can specify default values and filter the results using comparison operators.
