This is the most common way to look up values from databags from regular
|
|
|
|
|
Python code. Within templates you can also use the [bag
|
|
|
|
|
:ref](../../templates/globals/bag/) function which is easier to call.
|
|
|
|
|
|
|
|
|
|
The key is in dotted notation. For more information about this refer
|
|
|
|
|
to the main [databags :ref](../) documentation.

def translate(pad, alt, key):
|

|
|
|
return pad.databags.lookup('i18n.%s.%s' % (alt, key), key)
