go - 在水牛模型中指定多对多关系

Question

请问有人知道如何在水牛模型中指定多对多关系吗？

Answer 1

gobuffalo many_to_many ...

type Organization struct {
    ID               int                `json:"id" db:"id"`
    Users            Users              `many_to_many:"user_organizations"`
}


type User struct {
    ID                int                `json:"id" db:"id"`
    Organizations     Organizations      `many_to_many:"user_organizations" json:"-"`
}


type UserOrganization struct {
    ID             int          `json:"id" db:"id"`
    OrganizationID int          `json:"organization_id" db:"organization_id"`
    UserID         int          `json:"user_id" db:"user_id"`
    User           User         `belongs_to:"users"`
    Organization   Organization `belongs_to:"organizations"`
}

这些结构中的每一个都在它们自己的模型/*.go 文件中
