Since v15 its possible to create 'Salary Rule Parameters'. I'm trying to reference such a rule in a python code.

I'm aware of how to reference to, for example, an input parameter:



                    # Available variables:

                    #----------------------

                    # payslip: object containing the payslips

                    # employee: hr.employee object

                    # contract: hr.contract object

                    # rules: object containing the rules code (previously computed)

                    # categories: object containing the computed salary rule categories (sum of amount of all rules belonging to that category).

                    # worked_days: object containing the computed worked days.

                    # inputs: object containing the computed inputs.


                    # Note: returned value have to be set in the variable 'result'


So in order to reference an input variable, this is the syntax:

                    result = inputs.variable_name.amount * 0.10


But the documentation is not showing how to reference the newly introduced 'Salary Rule Parameter'. I already tried:

rule_parameter.variable_name.amount

and some other combinations of the word rule and parameter, but to no avail. Anybody knows how to reference it?

In v17, you can reference a rule parameter using the code payslip._rule_parameter('parameter_code')

are you sure to include the "_" before rule?

In v16 it would be payslip.rule_parameter('code') but in 17 you need to include "_" before.

Which version are you using?

I'm on 17.0.

I just tried:

result = payslip._rule_parameter('abc')

And it's working as expected. Thank you so much!

I was able to use a rule parameter in v16 like this:

result = payslip.rule_parameter('NameOfRuleParameter')

It returns the parameter value of it respecting the valid from date specified in the rule parameter.

argh. It gives me a nervous tick

Hmm, same problem here:

Fout: <class 'AttributeError'>: "'hr.payslip' object has no attribute 'rule_parameter'" while evaluating

Are you really sure, the synax is payslip.rule_parameter('<code-of-rule-paramter?') ?

You can use
payslip.rule_parameter('code_of_parameter').

The below is details from Odoo 15.0 commit.

In a salary rule, you can directly use `payslip.rule_parameter(code)`.
The version valid at the payslip end date is automatically chosen.

To retrieve a parameter value at a particular date,
use `self.env['hr.rule.parameter']._get_parameter_from_code(code, date)`.
The date is optional and set to today by default.

@Waleed, thanks for helping out. The first option you gave is already given by other people and is not working. I've tried the 2nd option you gave (retrieve a parameter value at a particular date) and this isn't working neither:

<class 'NameError'>: "name 'self' is not defined" while evaluating
"result = self.env['hr.rule.parameter']._get_parameter_from_code('abc', '2024-01-01')"

I'd say: please try it yourself. Create a "salary rule parameter" with code 'abc' and value '1'. Then create a "salary rule", choose 'python code' at 'amount type' and try to reference to the newly created salary rule parameter by entering:

result = payslip.rule_parameter('abc')

I'm pretty sure you will end up with the same error:

<class 'AttributeError'>: "'hr.payslip' object has no attribute 'rule_parameter'" while evaluating
"result = payslip.rule_parameter('abc')"
