先说物流状态的修改:
django-oscar自带的物流状态是四个:
OSCAR_INITIAL_ORDER_STATUS = 'Pending'
OSCAR_INITIAL_LINE_STATUS = 'Pending'
OSCAR_ORDER_STATUS_PIPELINE = {
'Pending': ('Being processed', 'Cancelled',),
'Being processed': ('Processed', 'Cancelled',),
'Cancelled': (),
}
我们改为:
OSCAR_INITIAL_ORDER_STATUS = "已经拍下,等待支付"
OSCAR_INITIAL_LINE_STATUS = "Pending"
#这个是供货商的状态,不需要理会
OSCAR_ORDER_STATUS_PIPELINE = {
"已经拍下,等待支付":("买家已经支付,等待卖家发货","取消订单"),
"买家已经支付,等待卖家发货":("卖家已经发货","取消订单"),#这里需要引入物流详情
"卖家已经发货": ("物流派件中,等待买家取件", "Cancelled"),
"物流派件中,等待买家取件": ("订单交易成功", "Cancelled"),
"订单交易成功":(),
"订单取消":(),
}
好了,有些同学想要定制修改上面的订单状态,但是一不小心在使用的时候就出现了:
The new status 'xxx' is not valid for this order
先从settings.py中开始检查:
①查看标点是不是都是统一的圆角或者半角
②引号请统一,别一会儿单引号一会儿双引号.
③不能跨key-value修改订单状态,上面我们看到,总共6个key-value对,
你可以在dashboard中对某个订单从"已经拍下,等待支付"改成"买家已经支付,等待卖家发货",
但是你不能在dashboard中对某个订单从"已经拍下,等待支付"直接改成"物流派件中"
#------------------------------------
如果上面检查过后还是报这个错,
那么我们来查看源码:
上面的③受源码/home/appleyuchi/.virtualenvs/python3.7/lib/python3.7/site-packages/oscar/apps/dashboard/views.py
中函数决定
def change_order_status(self, request, order):
# This method is pretty similar to what
# OrderDetailView.change_order_status does. Ripe for refactoring.
new_status = request.POST['new_status'].strip()
if not new_status:
messages.error(request, _("The new status '%s' is not valid")
% new_status)
elif new_status not in order.available_statuses():
print("new_status=",new_status)
print("order.available_statuses=",order.available_statuses())
messages.error(request, _("The new status '%s' is not valid for"
" this order") % new_status)
else:
handler = EventHandler(request.user)
old_status = order.status
try:
handler.handle_order_status_change(order, new_status)
except PaymentError as e:
messages.error(request, _("Unable to change order status due"
" to payment error: %s") % e)
else:
msg = _("Order status changed from '%(old_status)s' to"
" '%(new_status)s'") % {'old_status': old_status,
'new_status': new_status}
messages.info(request, msg)
order.notes.create(
user=request.user, message=msg, note_type=OrderNote.SYSTEM)
当订单状态选择不对或者"两个订单状态不相邻"(注意看key-value对)就会报错.
上面的函数调用了:
/home/appleyuchi/.virtualenvs/python3.7/lib/python3.7/site-packages/oscar/apps/order/abstract_models.py
def available_statuses(self):
"""
Return all possible statuses that this order can move to
"""
print("函数内self.pipeline=",self.pipeline)
print("返回的是:",self.pipeline.get(self.status, ()))
print("self_status=",self.status)
return self.pipeline.get(self.status, ())
而这个abstract_models.py会去读取OSCAR_ORDER_STATUS_PIPELINE变量.
上述就是关于这个问题的排查思路
然后问题来了,我们会发现在用户的历史订单中,
物流状态不显示,怎么办呢?
首先确保:
templates/oscar/customer/order/order_detail.html
中有下面的代码:
{% if order.status %}
<h2>{% trans 'Status' %}</h2>
{{order.status}}
<hr>
{% endif %}
