If you have a domain it can not be changed as the domain will ensure it.

But if i change the xml category on the product, problem will also be the 
same  (but with less impact, or i can prevent to change product category )?

No, any field can be stored on configuration but usually it is a
Property/MultiValue because it depends on the company.

I agree with Cedric here. Specially if you want to use it on a domain. Let me 
explain:

If you store it on the configuration, changing the value on the configuration 
may invalidate all the existing records domain. Creating a static category with 
xml records will prevent it.

I'll try this. It seems easier and without property :-)

I didn't thought this way :-)

Why using a Property field?

Only field of a model can be evaluated by PYSON.
There is the PYSON.Id but it will require that you create the category
in XML.

You can call the default_ method from the getter method.
But you need to have both because the getter will be called only once
the record is saved/created.

I think the creation of categories from XML could be a good option.

[tryton-dev] Using property (tryton 4.2) on domain field

2017-06-20 Thread Maxime Richez 
Hi,

Here's my small problem in Tryton 4.2, i want to filter products on a 
specific product category. I define those category as a property in a 
configuration.

My code is here: https://pastebin.com/wDF8qGtX

So in my main class (PrinterModel), i define a function field on product 
category to get the default category stored in configuration... 
(printer_category).

This function field is used in my domain for the product to get only 
products from a specific category (and children too)  (printer_model field)

My code wasn't working until i define a default_printer_category... code is 
redundant but it's working.

My question: is it necessary to use a function field for the domain or can 
i evaluate a function in domain ? If not, how to avoid code redundancy for 
default_ method and get_ method for the function field ? 
Is there a better way to implement this "filter" ? i'm looking for examples 
in code but unsuccessfully.

Thanks for help!
