You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: prom_alert_config_list_swaggergen.go
    path of file: ./repos/magma/orc8r/cloud/go/services/metricsd/obsidian/models
    
    the code of the file until where you have to start completion: // Code generated by go-swagger; DO NOT EDIT.

package models

// This file was generated
    
func (m PromAlertConfigList) Validate(formats strfmt.Registry) error {
	var res []error

	for i := 0; i < len(m); i++ {
		if swag.IsZero(m[i]) { // not required
			continue
		}

		if m[i] != nil {
			if err := m[i].Validate(formats); err != nil {
				if ve, ok := err.(*errors.Validation); ok {
					return ve.ValidateName(strconv.Itoa(i))
				} else if ce, ok := err.(*errors.CompositeError); ok {
					return ce.ValidateName(strconv.Itoa(i))
				}
				return err
			}
		}

	}

	if len(res) > 0 {
		return errors.CompositeValidationError(res...)
	}
	return nil
}
