<p>This is the most common way to look up values from databags from regular
|
|
Python code. Within templates you can also use the <a href="../../templates/globals/bag/" class="ref">bag</a> function which is easier to call.</p>
|
|
<p>The key is in dotted notation. For more information about this refer
|
|
to the main <a href="../" class="ref">databags</a> documentation.</p>
