Tips on GORM, Avoid Error about "duplicate column name: id"
The GORM is an super easy ORM solution for Go language.
But many people would get the error about
duplicate column name: id
Usually this comes from the model definition which has duplicated ID,
package model import (
"github.com/jinzhu/gorm"
) type Job struct {
gorm.Model // Already has ID, CreatedAt, UpdatedAt, DeletedAt 4 fields
Name string
}
We could remove the ID definition from our code and only use the one from grom.Model, or don't use the gorm.Model at all.
