Test PYSON statement

[2cadz (Christophe)]

Hello

Is there way to test some PYSON statement with proteus or tryton-console?
An example somewhere?

regards.

What do you want to test?

[2cadz (Christophe)]

Domain statement for example : If my writing are correct and understand why if it not correct

[ced (Cédric Krier)]

If it compiles, it is valid.

[nicoe (Nicolas Évrard)]

@ced

it is valid

It might be valid but not correct for the purpose intended

@2cadz

tryton-console

Here’s a quick session I did that checks an expression against a record

>>> from trytond.pyson import Eval, PYSONEncoder, PYSONDecoder
>>> from trytond.model.modelstorage import EvalEnvironment
>>> Party = pool.get('party.party')
>>> a = Party(1)
>>> env = EvalEnvironment(a, Party)
>>> b = Eval('name') == 'test'
>>> PYSONDecoder(env).decode(PYSONEncoder().encode(b))
False

I was almost there, I was just missing the EvalEnvironment, thank you @nicoe.
