Odoo-无法遍历模型记录 [英] Odoo - Cannot loop through model records

问题描述

每次模块安装或更新时，我都想调用一个方法.在该方法内部，我想遍历模型记录，但是只会遇到不同的错误.

I want to call a method every time my module gets installed or updated. Inside that method I want to loop through model records, but I'm only getting different errors.

此文档看起来非常简单: https://www.odoo.com /documentation/9.0/reference/orm.html

This documentation looks pretty straightforward: https://www.odoo.com/documentation/9.0/reference/orm.html

但这对我不起作用.我收到此错误:

But it doesn't work for me. I'm getting this error:

ParseError:'account.tax'对象在解析时没有属性'_ids'"

ParseError: "'account.tax' object has no attribute '_ids'" while parsing

这就是我所说的方法:

<openerp>
    <data>
        <function model="account.tax" name="_my_method" />
    </data>
</openerp>

我从这里的第一个答案中得到了这一点:

I took this from the first answer here: https://www.odoo.com/forum/help-1/question/how-can-i-execute-a-sql-statement-on-module-update-and-installation-6131

我的模特:

class my_account_tax(models.Model):
    _name = 'account.tax'
    _inherit = 'account.tax'

    def _my_method(self, cr, uid, ids=None, context=None):
        self.do_operation()

    def do_operation(self):
        print self
        for record in self:
            print record

基本上，这是文档中的复制粘贴.我只添加了方法参数cr，uid等.如果我将它们删除(并只留下"self")，则错误会有所不同:

It is basically a copy-paste from the docs. I only added method parameters cr, uid,.. If I take them away (and just leave 'self'), the error is a little different:

ParseError:"_ my_method()恰好接受1个参数(给定3个参数)"

ParseError: "_my_method() takes exactly 1 argument (3 given)"

但也说明不了什么.

推荐答案

使用新api

@api.multi    #if you use the new api you don't have to list all parameter in the function
def _my_method(self): 

但是您可以像这样保持它并在模型上做一个池，而不是循环抛出得到的结果，即不要使用self 如果您使用新的api，请使用:self.env['model_name'].search([domain])

but you can keep it like that and do a pool on your model than loop throw the result that you get don't use self if you use the new api use : self.env['model_name'].search([domain])
