Bug description:
Hi
We are working on fleet_maintenance. (not the version in extra-addons but this
version :
https://code.launchpad.net/~akretion-team/openobject-addons/fleet_maintenance_anevia)
We use function.fields with the type boolean and the option store=True.
When we check in the database, we don't see any value 'False' in the column of
our field. Only the values Null or True are present. After some code
inspection, we found where is the bug.
Indeed, on a standard field boolean, the value is force to "True" or "False".
On a function field, the function called to set the field to "False" or "True"
returns a wrong result : it returns the value "True" or "None".
To see what is wrong, add some print in the orm.py line 3003 :
result = self._columns[f].get(cr, self, ids, f, uid, context=context)
for id,value in result.items():
+ print 'value', value
+ print 'f', f
+ print 'symbol type', self._columns[f]._type
+ print
'self._columns[f]._symbol_set[1](True)',self._columns[f]._symbol_set[1](True)
+ print
'self._columns[f]._symbol_set[1](False)',self._columns[f]._symbol_set[1](False)
if self._columns[f]._type in ('many2one', 'one2one'):
try:
value = value[0]
except:
pass
The result of the print are :
value False
f is_expired
symbol type boolean
self._columns[f]._symbol_set[1](True) True
self._columns[f]._symbol_set[1](False) None
In this case (only for a function field with the type boolean, not for a pure
boolean field) the method _symbol_set[1](False) returns "None" and not "False".
I try to modify the _symbol_set method in field.py
class boolean(_column):
_type = 'boolean'
_symbol_c = '%s'
_symbol_f = lambda x: x and 'True' or 'False'
_symbol_set = (_symbol_c, _symbol_f)
with incorrect value in order to crash openerp, but it doesn't use this code
for a function fields. Here is the problem : it should execute this code as
it's a boolean field.
Hope reporting this bug will help you.
For people which are affected by this bug you can use this patch.
