示例1: AddEnvironmentUser
// AddEnvironmentUser adds a new user to the database.
func (st *State) AddEnvironmentUser(user, createdBy names.UserTag, displayName string) (*EnvironmentUser, error) {
// Ensure local user exists in state before adding them as an environment user.
if user.Provider() == names.LocalProvider {
if _, err := st.User(user.Name()); err != nil {
return nil, errors.Annotate(err, fmt.Sprintf("user %q does not exist locally", user.Name()))
}
}
// Ensure local createdBy user exists.
if createdBy.Provider() == names.LocalProvider {
if _, err := st.User(createdBy.Name()); err != nil {
return nil, errors.Annotate(err, fmt.Sprintf("createdBy user %q does not exist locally", createdBy.Name()))
}
