Help on Pyson Statement

[Maxime Richez]

Hi,

We are looking to define a specific rule on a button (Models-> Models Access -> Buttons). Rule would be : 2 users needs to validate button if amount is greater than a specific value.
We try this expression : [["total_amount", ">", 500]]
This is not working. What should be the correct expression ?
Thanks !

You have some examples in the test suite:

http://hg.tryton.org/trytond/file/34073513c887/trytond/tests/test_modelview.py#l194

Have you tried?:

Eval('self', {}).get('total_amount', 0) > 500

Hope it helps.

Thanks but we are testing from the tryton client, and expression is not a valid Pyson expression. Is there a way to convert your expression in the gui client ?
We convert your expression with PYTHONEncoder and then we introduce the result in the GUI, and it's working whith this value:
{"s2": 500, "s1": {"d": 0, "k": "total_amount", "__class__": "Get", "v": {"d": {}, "__class__": "Eval", "v": "self"}}, "e": false, "__class__": "Greater"}

Is there a tool in the gui to convert expression to Pyson ?

Indeed there is a widget to manipulate the pyson statements on the
tryton client [1]. You should be able to enter the pyson expresion on
client and it will automatically encode the values when sending to the
server.

But I see the widget is not activated for this field.

I will create an issue in order to fix it.

Thanks,

It will be great if you can test it :)

We have the pyson widget now. I think the condition field is missing it.
