How to disable default error logger in Go-Gorm

In Go Gorm, by default, Gorm uses its built-in error logger to record warnings and error messages. This is very useful for development and debugging, but in production environments, you might prefer to use your own logging mechanism or, for performance reasons, you may want to completely disable these logs.

To disable the default error logger in Gorm, you can set the log level to silent. This can be achieved by using the Logger method and Default.LogMode from the gorm/logger package. Here is a simple example:

go
package main

import (
    "gorm.io/gorm"  // Corrected from "dorm" to "gorm" for accuracy
    "gorm.io/driver/sqlite"
    "gorm.io/gorm/logger"
)

func main() {
    // Connect to database
    db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{
        Logger: logger.Default.LogMode(logger.Silent),
    })
    if err != nil {
        panic("failed to connect database")
    }

    // Use db for operations...
}

In this example, we first import the necessary packages, including gorm.io/gorm and gorm.io/gorm/logger. When initializing Gorm, we specify the logging mode via the Logger field in the gorm.Config struct. The line logger.Default.LogMode(logger.Silent) sets the log level to Silent, which disables all log recording.

After this configuration, Gorm will not output any logs, including error and warning messages. This can help reduce log noise and improve application performance. However, in production environments, it is generally recommended to at least log error messages, and you should choose an appropriate log level based on your actual needs.
