Python3函数缺少3个必需的位置参数

Question

我试图用odoo 14编写一个复制函数。

但我得到了以下错误：

  Odoo Server Error
  Traceback (most recent call last):
    File "/vagrant/odoo/odoo/addons/base/models/ir_http.py", line 237, in _dispatch
      result = request.dispatch()
    File "/vagrant/odoo/odoo/http.py", line 682, in dispatch
      result = self._call_function(**self.params)
    File "/vagrant/odoo/odoo/http.py", line 358, in _call_function
      return checked_call(self.db, *args, **kwargs)
    File "/vagrant/odoo/odoo/service/model.py", line 94, in wrapper
      return f(dbname, *args, **kwargs)
    File "/vagrant/odoo/odoo/http.py", line 346, in checked_call
      result = self.endpoint(*a, **kw)
    File "/vagrant/odoo/odoo/http.py", line 911, in __call__
      return self.method(*args, **kw)
    File "/vagrant/odoo/odoo/http.py", line 530, in response_wrap
      response = f(*args, **kw)
    File "/vagrant/odoo/addons/web/controllers/main.py", line 1363, in call_button
      action = self._call_kw(model, method, args, kwargs)
    File "/vagrant/odoo/addons/web/controllers/main.py", line 1351, in _call_kw
      return call_kw(request.env[model], method, args, kwargs)
    File "/vagrant/odoo/odoo/api.py", line 396, in call_kw
      result = _call_kw_multi(method, model, args, kwargs)
    File "/vagrant/odoo/odoo/api.py", line 383, in _call_kw_multi
      result = method(recs, *args, **kwargs)
  Exception

  The above exception was the direct cause of the following exception:

  Traceback (most recent call last):
    File "/vagrant/odoo/odoo/http.py", line 638, in _handle_exception
      return super(JsonRequest, self)._handle_exception(exception)
    File "/vagrant/odoo/odoo/http.py", line 314, in _handle_exception
      raise exception.with_traceback(None) from new_cause
  TypeError: copy_func() missing 3 required positional arguments: 'cr', 'uid', and 'ids'

我一直在寻找解决方案，但它无法成功地复制。

def copy_func(self, cr, uid, ids, context=None):
    _logger.info('=== copy_func start ===')

    for record in self.browse(cr, uid, ids):
        formbas_obj = self.pool.get('com.formmst')
        defaults = {
            'form_no': record.form_no,
            'com_orgbas_id': record.com_orgbas_id.id if record.com_orgbas_id else False,
        }
        formbas_obj.copy(cr, uid, record.com_formmst_id.id, defaults)
    _logger.info('=== copy_func end ===')

单击“复制”按钮时调用此函数。在这里输入图像描述

<record id="form_com_formbas_copy_wizard" model="ir.ui.view">
    <field name="name">form.com.formbas.copy.wizard</field>
    <field name="model">com.formbas.copy.wizard</field>
    <field name="arch" type="xml">
        <form>
            <group col="4">
                <field name="com_formmst_id"/>
                <newline/>
                <field name="form_no"/>
            </group>
            <footer>
                <button string="Copy" name="copy_func" type="object" class="oe_highlight"/>
                or
                <button string="Cancel" special="cancel" type="object" class="oe_link"/>
            </footer>
        </form>
    </field>
</record>

我为此挣扎了很长一段时间。任何形式的帮助都将是非常感谢的！

Answer 1

使用。为此，删除函数签名- cr、uid、id、context=None。

旧api

def afun(self, cr, uid, ids, context=None):

新API

def afun(self):

def copy_func(self):
    _logger.info('=== copy_func start ===')

    for record in self:
        formbas_obj = self.env['com.formmst'].search(['id', '=', 121])
        defaults = {
            'form_no': record.form_no,
            'com_orgbas_id': record.com_orgbas_id.id if record.com_orgbas_id else False,
        }
        formbas_obj.write(defaults)
    _logger.info('=== copy_func end ===')

在函数中，为formbas_obj指定确切的对象，以便将默认值写入。
