Title:
Selection does not work for (stored) function fields
Status in OpenERP Server:
Confirmed
Bug description:
*A definition for field "period_id" in table "xxx.yyy"
*
[.xml]:
<record model="ir.ui.view" id="xxx_yyy_list">
<field name="name"xxx.yyy.list</field>
<field name="model">xxx.yyy</field>
<field name="type">tree</field>
<field name="arch" type="xml">
<tree string="blah blah">
<field name="period_id" readonly="1" select="1"/>
</tree>
</field>
</record>
[.py]:
_columns = \
{ 'period_id' : fields.function
( _func
, method = True
, string = 'Period'
, type = 'many2one'
, obj = 'account.period'
, store = True
, select = True
, required = True
)
}
*results in a traceback ("operator does not exist" in sql_db.py) when a
search is filtered with a "period_id":
*
ProgrammingError: FEHLER: Operator existiert nicht: integer ~~* unknown
ZEILE 1: ...ne" where (xxx_yyy.period_id ilike E'%...
*The SQL-snippet shows that the system tries a string-comparison
("ilike") on the reference to the other table - which ist wrong!
The server log shows the following message:
*TIP: Kein Operator stimmt mit dem angegebenen Namen und den
Argumenttypen überein. Sie müssen möglicherweise ausdrückliche
Typumwandlungen hinzufügen.
*("Operator does not match argument-type. Try a type-cast.")
When the definition is changed to
*
_columns = \
{ 'period_id' : fields.many2one
( 'account.period'
, 'Period'
, select = True
, required = True
, readonly = True
)
}
*it works flawlessly
