创建时

'capname': fields.function(

),

推荐答案

您必须添加一个反函数以使该字段可编辑.此参数在OpenERP v7中称为fnct_inv.一个例子:

You must add a inverse function to make the field editable. This parameter is called fnct_inv in OpenERP v7. An example:

def _get_test(self, cr, uid, ids, name, args=None, context=None):
    result = dict.fromkeys(ids, False)
    for line in self.browse(cr, uid, ids, context=context):
        if line.test:
            result[line.id] = line.test
    return result       

def _set_test(self, cr, uid, id, field_name, field_value, args=None, context=None):
    obj = self.browse(cr, uid, id)
    for record in obj:
        if record.test != field_value:
            # The record already exists

            ...

            cr.execute(
                'UPDATE your_table '
                'SET test=%s '
                'WHERE id=%s', (field_value, id)
            )
        else:
            # It is a new record 
            # (or the value of the field was not modified)

    return True

_columns = {
    'test': fields.function(
        string='String for testing', 
        fnct=_get_test, 
        fnct_inv=_set_test,            
        type='char', 
        size=50, 
        store=True,
    ),
}
