我认为这是因为您滥用了 Odoo ORM。首先，在 Odoo 中，您永远不会像这样声明 class 级别的属性...
counter = 0
global_po_id = None
line_counter = 0
first_line = None
然后你在这里引用它:
if procurement_order.first_line
问题是 procurement_order 的类型是 osv.osv 但这行代码应该使用浏览记录。当它试图追踪并从它认为是浏览记录的内容中懒惰地加载数据项时，它会到达需要使用游标但没有游标可供使用的地步，因此出现错误。
最好将 osv.osv class 视为只读元数据 class，它在数据库中描述了您的 table，但也让您有一些已定义静态或 class 方法。
您使用的procurement_order应该是浏览的结果
my_procurement_order = self.browse(cr, uid, ids[0], context=context)
下一个问题是您不能在 运行 时将 first_line 之类的值分配给浏览记录，它们是只读的（注意这在 Odoo 8 new API 但那是另一回事了）。
这里的一个常见做法是维护一个类似本地字典的东西，你可以参考：
first_lines = {my_procurement_order.id: a_line}

我认为这是因为您滥用了 Odoo ORM。首先，在 Odoo 中，您永远不会像这样声明 class 级别的属性...
counter = 0
global_po_id = None
line_counter = 0
first_line = None
然后你在这里引用它:
if procurement_order.first_line
问题是 procurement_order 的类型是 osv.osv 但这行代码应该使用浏览记录。当它试图追踪并从它认为是浏览记录的内容中懒惰地加载数据项时，它会到达需要使用游标但没有游标可供使用的地步，因此出现错误。
最好将 osv.osv class 视为只读元数据 class，它在数据库中描述了您的 table，但也让您有一些已定义静态或 class 方法。
您使用的procurement_order应该是浏览的结果
my_procurement_order = self.browse(cr, uid, ids[0], context=context)
下一个问题是您不能在 运行 时将 first_line 之类的值分配给浏览记录，它们是只读的（注意这在 Odoo 8 new API 但那是另一回事了）。
这里的一个常见做法是维护一个类似本地字典的东西，你可以参考：
first_lines = {my_procurement_order.id: a_line}
