I want to create a module that depends on product_measurements but also adds the “length” fields to product.product (instead of relying on product.template).
At first I thought that I would just have to add the field to _no_template_field but all scenarios fail with something like:
File ".../tests/scenario_production_priority.rst", line 142, in scenario_production_priority.rst
Failed example:
template.save()
Exception raised:
Traceback (most recent call last):

sqlite3.OperationalError: no such column: a.length_uom
If I add the __register__() method and use pdb I see that the length fields are already created as Function fields when __register__() is called (before calling super) so register will not create those fields in the database.
Am I missing something?
