odoo同时创建多条记录

dodo

如果要创建多条记录（例如几千），只能通过多次调用create方法吗，有没有批量操作的方法

Siyuan

可以直接cr.execute 运行psql 命令，用 insert into 增加记录。

前提是你要对新建记录的表的结构非常熟悉

@siyuan 直接用orm没法实现是吗

一般不会在addons模块内部来创建几千条记录这样的代码。大量记录的创建有几个方法一个是 @Siyuan 提到的用SQL来直接对数据库操作，无论是在odoo框架下用cr.execute执行还是直接用SQL外部工具来创建。这种方法的优势是效率高，速度快，但是弱点是会旁路Odoo对象内部的所有约束，关联操作等。

多条记录创建一般的做法是使用Odoo内置的导入工具导入（base_import),

当然如果数据比较复杂，你也可以使用xml-rpc工具导入，其原理一样是循环调用create方法。

@dodo orm 的话，除非你改框架，这涉及到default，compute 等字段的计算；

具体要参考models.py 下面单个记录的create的方法了。

@api.model
@api.returns('self', lambda value: value.id)
def create(self, vals):
    """ create(vals) -> record

    Creates a new record for the model.

    The new record is initialized using the values from ``vals`` and
    if necessary those from :meth:`~.default_get`.

    :param dict vals:
        values for the model's fields, as a dictionary::

            {'field_name': field_value, ...}

        see :meth:`~.write` for details
    :return: new record created
    :raise AccessError: * if user has no create rights on the requested object
                        * if user tries to bypass access rules for create on the requested object
    :raise ValidateError: if user tries to enter invalid value for a field that is not in selection
    :raise UserError: if a loop would be created in a hierarchy of objects a result of the operation (such as setting an object as its own parent)
    """
    self.check_access_rights('create')

    # add missing defaults, and drop fields that may not be set by user
    vals = self._add_missing_default_values(vals)
    for field in itertools.chain(MAGIC_COLUMNS, ('parent_left', 'parent_right')):
        vals.pop(field, None)

    # split up fields into old-style and pure new-style ones
    old_vals, new_vals, unknown = {}, {}, []
    for key, val in vals.iteritems():
        field = self._fields.get(key)
        if field:
            if field.column or field.inherited:
                old_vals[key] = val
            if field.inverse and not field.inherited:
                new_vals[key] = val
        else:
            unknown.append(key)

    if unknown:
        _logger.warning("%s.create() includes unknown fields: %s", self._name, ', '.join(sorted(unknown)))

    # create record with old-style fields
    record = self.browse(self._create(old_vals))

    # put the values of pure new-style fields into cache
    record._cache.update(record._convert_to_cache(new_vals))
    # mark the fields as being computed, to avoid their invalidation
    for key in new_vals:
        self.env.computed[self._fields[key]].add(record.id)
    # inverse the fields
    for key in new_vals:
        self._fields[key].determine_inverse(record)
    for key in new_vals:
        self.env.computed[self._fields[key]].discard(record.id)

    return record

建议调用create实现批量创建
