How to get fields translations

[oscarQ (Òscar Queraltó)]

I want to get a field translation in a specific language if it exists.
I saw some code that is just updating the context language before getting the field value so I tried but it’s returning me the default language value:

context = {}
if self.purchase and self.purchase.party and self.purchase.party.lang:
    context['language'] = self.purchase.party.lang.code
with Transaction().set_context(context):
    self.product_supplier.name

Assuming that exists a translation for the product supplier name and also that I am setting the expected lang code, should it works or I am missing something else?

You should re-browse the instance with the proper context. Instances keep a copy of the context where they had been initialized and always use this context.

So your code should be updated to:

ProductSuplier = Pool().get(...)
context = {}
if self.purchase and self.purchase.party and self.purchase.party.lang:
    context['language'] = self.purchase.party.lang.code
with Transaction().set_context(context):
    product_supplier = ProductSupplier(self.product_supplier.di)
    return product_supplier.name
