Question

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，如self，cr，uid，id，context但在V8中我认为不需要这些参数。在我的自定义模块中，我尝试根据从mrp获得的信息创建采购订单。我已经做了一个自定义的计算，计算出要生产10000本书所需的纸张数量。经过计算，这些信息应该去购买发票。产品将从物料清单中获得，数量来自所需的纸张数量和单位价格来自产品成本属性。我无法解决此错误“方法只需1个参数（5个给定）”

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'}

Answer 1

如果您从模型中的其他方法调用generate_purchase_order方法，则使用装饰器@api.multi作为该方法。

同样在您的generate_purchase_order方法中，替换

for order in self.browse():

通过

for order in self:

修改

@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'}

TypeError：generate_purchase_order（）只取1个参数（给定5个）
