具体问题见下
Description
// 短信模板
type SMSTemplate struct {
gorm.Model
Name string // 模板名称，必填
Description string // 模板描述，可选
TemplateID string // 模板ID，必填
Type string // 模板类型，必填
Vars map[string]bool `gorm:"serializer:json"` // 模板变量名及必须性
}
// 短信关联记录
type SMSRecord struct {
gorm.Model
TemplateID int
Template SMSTemplate `gorm:"foreignKey:TemplateID;references:ID;constraint:OnUpdate:CASCADE,OnDelete:CASCADE"` // 关联模板
APPID string // 关联应用ID，必填
Name string // 记录描述，必填
}
- 当按上面模型声明时，会生成不正确的table sql语句。
- 当
SMSRecord.Template移除foreignKey:TemplateID保留references:ID时，生成table sql符合预期 - 当
SMSRecord.Template同时移除foreignKey:TemplateID和references:ID时，生成table sql符合预期
驱动版本
gorm.io/driver/postgres v1.3.5
gorm.io/gorm v1.23.5
结论
当gorm model同时指定foreignKey和references时如果关联模型同时存在foreignKey相同字段时，不能正确生成table sql语句。
