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"`
}

Each of these structs are in their own models/*.go file
