    ValueError: Expected singleton: report.stock.config(21, 16) 


I have code: 

    report_ids = fields.Many2many(comodel_name='report.stock.config', relation='report_stock_write_off_config_rel',    column1='stock_write_off_id', column2='stock_config_id', string='Report', domain=[('test','=','t')]) 
    date_from = fields.Datetime('Date From', required=True) 
    date_to = fields.Datetime('Date To', required=True) 
    detailed = fields.Boolean('Detailed Report') 

@api.multi 
def print_report(self, data): 
    data['report_ids'] = self.report_ids.id 
    data['date_from'] = self.date_from 
    data['date_to'] = self.date_to 
    data['detailed'] = self.detailed 
    return self.env['report'].get_action(self, 'talm_stock.report_stock_write_off', data=data) 

XML

<record id="view_stock_write_off_wizard" model="ir.ui.view"> 
    <field name="name">Stock Write Off</field> 
    <field name="model">stock.write.off</field> 
    <field name="arch" type="xml"> 
     <form string="Stock Write Off"> 
      <group> 
       <field name="report_ids" widget="many2many_tags"/> 
       <field name="date_from"/> 
       <field name="date_to"/> 
       <field name="detailed"/> 
      </group> 
      <footer> 
       <button name="print_report" string="Retrieve write off data" type="object" class="oe_highlight"/> 
       or 
       <button string="Cancel" class="oe_link" special="cancel"/> 
      </footer> 

Как может Я решаю эту проблему? Мне нужно получить одну или несколько записей из report.stock.config(). Например, report.stock.config (21, 16)

Answer 1

проблема заключается в stock_write_off .py

File "/ksi/addons/talm/wizard/stock_write_off.py", line 20, in print_report 
data['report_ids'] = self.report_ids.id 

просто использовать self.report_ids.ids вместо self.report_ids.id

это будет правильный синтаксис: данные ['report_ids'] = self.report_ids.ids
