Hello, 

Yes, this can be achieved within Payroll Rule Python code.

For contract salary, contract.wage should generally be available if the contract object is present in the salary rule context. If it throws name 'contract' is not defined, try accessing it through the payslip object:

payslip.contract_id.wage

For unpaid leave days, you can usually retrieve them from worked days lines, for example:

worked_days.UNPAID.number_of_days

(Replace UNPAID with the actual code configured for your unpaid leave/work entry type.)

Please verify the work entry code in your payroll configuration because it may differ in your setup.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.

Hello
It is changed to hr.version in earlier Odoo version.

You can write small piece of code anywhere to print the current object's attribute lists.
Like this: version._fields.keys()
