我正在尝试执行芹菜任务,代码如下。
task.py
from .models import OrderItem
from cart.cart import Cart
from .forms import OrderCreateForm
@task(name="create_order")
def create_order(request):
cart = Cart(request)
if request.method == 'POST':
form = OrderCreateForm(request.POST)
if form.is_valid():
order = form.save()
for item in cart:
try:
OrderItem.objects.create(order=order,
product=item['product'],
price=item['price'],
quantity=item['quantity'])
except:
pass
cart.clear()
return None
else:
form = OrderCreateForm()
return None
views.py
from .models import OrderItem, Order
from cart.cart import Cart
from .tasks import create_order
def order_create(request, order_id):
order = Order.objects.get(id=order_id)
cart = Cart(request)
create_order.delay(order.id)
return render(request,'orders/order_created.html', {'cart': cart, 'order': order})
urls.py
from .views import order_create
urlpatterns = [
url(r'^create/$',order_create, name='order_create'),
]
执行代码时,我收到错误"order_create() 恰好需要 2 个参数(给定 1 个)"。希望有人能帮我解决。谢谢。
以下是我的工作代码,它在创建订单后发送邮件,但我想将整个视图功能更改为芹菜任务。
@task(name="send_mail_to_custormer")
def order_created(order_id):
order = Order.objects.get(id=order_id)
subject = 'Order nr. {}'.format(order.id)
message = 'Dear {} {},nnYou have successfully placed an order. Your order id is {}'.format(order.first_name,
order.last_name, order.id)
from_email = settings.EMAIL_HOST_USER
to_email = [order.email]
mail_sent = send_mail(
subject,
message,
from_email,
to_email,
fail_silently=False
)
return mail_sent
views.py
def order_create(request):
cart = Cart(request)
if request.method == 'POST':
form = OrderCreateForm(request.POST)
if form.is_valid():
order = form.save()
for item in cart:
try:
OrderItem.objects.create(order=order,
product=item['product'],
price=item['price'],
quantity=item['quantity'])
except:
pass
cart.clear()
order_created.delay(order.id)
return render(request,'orders/order_created.html', {'cart': cart, 'order': order})
else:
form = OrderCreateForm()
return render(request, 'orders/order_create.html', {'cart': cart, 'form': form})
将 URL
定义更改为下面的 URL,您错过了将order_id作为参数传递给视图
url(r'^create/(?P<order_id>w+)/$',order_create, name='order_create'),
您应该将order_id与 URL 一起传递。
