# Environment Variables

/// tip

If you already know what "environment variables" are and how to use them, feel free to skip this.

///

An environment variable (also known as "**env var**") is a variable that lives **outside** of the Python code, in the **operating system**, and could be read by your Python code (or by other programs as well).

You can probably skip this part.

///

There's an alternative way to define this logic to be executed during *startup* and during *shutdown*.

	if embeddedRelations == nil {
		return nil
	}
	names := make([]string, 0, len(embeddedRelations.Relations)+len(embeddedRelations.EmbeddedRelations))
	for _, relation := range embeddedRelations.Relations {
		// skip first struct name
		names = append(names, strings.Join(relation.Field.EmbeddedBindNames[1:], "."))
	}
	for _, relations := range embeddedRelations.EmbeddedRelations {
		names = append(names, embeddedValues(relations)...)
	}
