Actions for workflow state: Condition check

[naresh]

Need to write a condition on subtracting dates.
Here is the Usecase:

While uploading the document we will define the metadata expiry_date ex.“2023-05-10”, we need a condition that will check the current_date and expiry_date if current_date > expiry_date we need to a add tag called expired. but we don’t know how to write conditions using Django-built template tags and filters

Can someone guide me on this?
Thanks in advance

{# grab the current date and time string #}
{% now "h:m m-d-y" as date_time_string %}

{# convert the date time string into a date object #}
{% set date_time_string|date_parse as now_date_object %}

{# convert the metadata expiration date string into a date object #}
{% set document.metadata_values_of.expiry_date|date_parse as expiration_date_object  %}
{% if now_date_object > expiration_date_object %}
True
{% endif %}

@roberto.rosario Thanks for the Update

I tried with the above condition that has been provided, but I end with an error
Basically, we are adding a tag to the document on a state is exits with expiry condition

step1: we create workflow->state->action->condition

step2: Uploading document with the metadata
expirydate: 2023-05-01

step3:On state change i am getting error

Error in Logs:
File “/opt/mayan-edms/lib/python3.9/site-packages/dateutil/parser/_parser.py”, line 646, in parse

• raise ParserError(“String does not contain a date: %s”, timestr)*
  dateutil.parser._parser.ParserError: String does not contain a date:

We found that metadata value is not fetching, so it is an empty string date parser failing it.
we tried with condition

{% set "2023-05-01"|date_parse as expiration_date_object  %}
{{expiration_date_object}}

it is working as expected, it is converting it as a date object but when we add

{% set document.metadata_values_of.expirydate|date_parse as expiration_date_object  %}
{{ expiration_date_object  }}

it is failing for this
I didn’t understand why it is not getting the metadata value
Any Help here?

The same code is working on the document sandbox but when we tried in the workflow state action condition is not working
