community.go

func (Community) TableName() string 用于指定数据库表名

type Community struct {ID            int64     `json:"id" gorm:"primary_key;auto_increment"`CommunityID   string    `json:"community_id" gorm:"unique;not null"` // 社区IDCommunityName string    `json:"community_name" gorm:"not null"`      // 社区名称Introduction  string    `json:"introduction"`                        // 社区简介CreateTime    time.Time `json:"create_time"`                         // 创建时间UpdateTime    time.Time `json:"update_time"`                         // 更新时间
}func (Community) TableName() string {return "community"
}
