Hello all,

In Odoo 8.

Trying to write a new function field warehouse_id in the stock.quant model. This field must be computed and stored.

I get an error and I can't manage it.

Why am I not able to display my log text '_get_warehouse_id BEGIN'. I always use logger to display text like this and it always work. But this time, I can't get the text. So the function doesn't seem to be called.

When odoo start, it tries to calculate de new column :

2017-02-26 17:53:22,364 7372 INFO odoo-8 openerp.models: storing computed values of fields.function 'warehouse_id'

And just after, I get this error :

Traceback (most recent call last):
