【中文标题】类型错误:generate_purchase_order() 只需要 1 个参数(给定 5 个)【英文标题】:TypeError: generate_purchase_order() takes exactly 1 argument (5 given) 【发布时间】:2016-07-12 06:14:05 【问题描述】:

我正在尝试将 openerp 7 代码转换为 odoo8。在 V7 中,browse() 方法有几个参数,例如 self、cr、uid、ids、context,但在 V8 中,我认为这些都不需要。在我的自定义模块中,我试图根据从 mrp 获得的信息创建采购订单。我已经对要制造 10000 本书需要多少公斤纸进行了自定义计算。计算后,此信息应转到采购发票。产品将从材料清单中获得,数量从所需纸张的公斤数和来自产品成本属性的单价。我无法解决此错误“方法只需要 1 个参数(给定 5 个)”

mrp.py,

from openerp import models
class mrp_production(models.Model):
    _inherit = 'mrp.production'

    def generate_purchase_order(self,supplier_id,warehouse_id):
        purchase_obj = self.env['purchase.order']
        purchase_line_obj = self.env['purchase.order.line']
        warehouse_obj = self.env['stock.warehouse']

        warehouse = warehouse_obj.browse(warehouse_id)
        if not warehouse:
            return False
        if isinstance(warehouse, list):
            warehouse = warehouse[0]

        for order in self:
            vals = 
            vals = purchase_obj.onchange_partner_id()
            vals['origin'] = order.name
            vals['partner_id'] = supplier_id

            vals['warehouse_id'] = warehouse_id
            vals['location_id'] = warehouse.lot_stock_id.id
            vals['date_order'] = order.date_planned
            purchase_id = purchase_obj.create(vals)

            for line in self.bom_id.bom_line_ids:
                if not line.product_id:
                    continue

                line_vals = purchase_line_obj.onchange_product_id(line.product_id.id,
                                                line.product_uom_qty, line.product_uom.id, supplier_id,
                                                date_planned=line.date_planned)['value']
                line_vals['name'] = line.name
                line_vals['product_id'] = line.product_id.id
                if not line_vals.get('price_unit', False):
                    line_vals['price_unit'] = line.product_id.list_price
                line_vals['product_uom'] = line.product_uom.id
                line_vals['product_uom_qty'] = 181.13
                line_vals['order_id'] = purchase_id
                purchase_line_obj.create(line_vals)

        return True

generate_purchase_order.py,

from openerp import models,fields,api
class generate_purchase_order(models.Model):
    _name = 'mrp_to_purchase_order.generate_purchase_order'
    _description = 'Generate Purchase Order'

    partner_id =  fields.Many2one('res.partner', 'Supplier', required=True, domain="[('supplier','=',True)]")
    warehouse_id = fields.Many2one('stock.warehouse', 'Warehouse', required=True)

    @api.multi
    def onchange_partner_id(self,partner_id):
        return 

    def generate_purchase_order(self):
        for wizard in self:
            #mrp_order_ids = [context['active_id']]
            mrp_obj = self.env['mrp.production']
            mrp_obj.generate_purchase_order(wizard.partner_id.id, wizard.warehouse_id.id)
        return  'type': 'ir.actions.act_window_close'

【问题讨论】:

【参考方案1】:

如果您从模型中的某个其他方法调用generate_purchase_order 方法,则为该方法使用装饰器@api.multi

同样在你的generate_purchase_order 方法中,替换

for order in self.browse():

for order in self:

编辑

@api.multi
def generate_purchase_order(self):
    for wizard in self:
        #mrp_order_ids = [context['active_id']]
        mrp_obj = self.env['mrp.production']
        # Get the mrp record
        mrp_rec = code to get mrp record
        mrp_rec.generate_purchase_order(wizard.partner_id.id, wizard.warehouse_id.id)
        return  'type': 'ir.actions.act_window_close'

【讨论】:

generate_purchase_order 方法被另一个类调用 在你的代码中更新那个方法,这样我就可以检查你的“generate_purchase_order”中的哪一行导致了错误? browse() 问题已解决,但我现在收到此错误:TypeError: generate_purchase_order() 只需要 1 个参数(给定 5 个) 我在第一个文件而不是第二个文件中从 mrp 获取信息。在第二个文件中,我只是发送合作伙伴和仓库的 ID。
