1"""Model values. 

2 

3Each subpackage implements one value type (``gws.ext.object.modelValue``). 

4Values are configured in the ``values`` list of a model field and compute the 

5field value when a feature is read, created or updated (``forRead``, 

6``forCreate``, ``forUpdate``). With ``isDefault``, the value is used only when 

7no other value is provided. Values also serve as bounds for range validators.

9- ``current_timestamp``: the current date and time. 

10- ``current_user``: the login name of the current user, or a formatted string. 

11- ``expression``: the result of a Python expression. 

12- ``format``: a format string applied to the feature attributes. 

13- ``static``: a fixed value.

18 name "updated_by"

21 }
