python - 如何通过CreateView保存表单后转到另一个页面

Question

添加新订单后我不想进入 order_list 页面。

尝试使用反向和反向惰性方法也只是直接将页面地址值设置为 success_url，如 success_url = 'orders/order_list' 或 sucess url = 'order_list' 但它总是返回 Http 405 错误。

View .py

django.shortcuts import render
from django.urls import reverse_lazy
from django.views import View
from django.views.generic import ListView, DetailView, CreateView
from django.http import HttpResponse, HttpResponseRedirect
from django.contrib.auth.mixins import PermissionRequiredMixin, LoginRequiredMixin
from .models import Order
from .forms import CreateOrder
from django.contrib.auth.decorators import login_required



# Create your views here.

class OrderCreateView(LoginRequiredMixin, PermissionRequiredMixin, CreateView):

        login_url = '/login_required'
        permission_required = 'orders.add-order'
        model = Order
        success_url = reverse_lazy('orders:order_list')

        fields = ['airport', 'direction', 'adress', 'client', 'telephone', 'flight_number', 'plane', 'pick_up', 'gate', 'driver']

url.py

from django.contrib import admin
from django.urls import path
from django.contrib.auth import views as auth_views


from orders.views import OrderCreateView, OrderListView, AboutView, LoginRequiredView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('add_order/', OrderCreateView.as_view(template_name="orders/add_order.html"), name="add_order"),
    path('order_list/', OrderListView.as_view(), name="order_list"),
    path('login/', auth_views.LoginView.as_view(template_name="pages/login.html"), name="login"),
    path('logout/', auth_views.LogoutView.as_view(template_name="pages/logout.html"), name="logout"),
    path('about/', AboutView.as_view(), name="about"),
    path('login_required/', LoginRequiredView.as_view(), name='login_required')

]

add_order.html

{% extends 'base.html' %}
{% load static %}
{% load crispy_forms_tags %}


{% block content %}
    <div class="container" style="width: 40%; height: 80%;">


            <div class="page header">
                <h1>Add new order</h1>
            </div>
            <form action="/order_list/" method="post">
                {% csrf_token %}
                {{ form|crispy }}
                <button type="submit" class="btn btn-success">Save order</button>
            </form>
        </div>


{% endblock %}

有什么想法我做错了什么吗？

Answer 1

更改:

success_url = reverse_lazy('orders:order_list')

致:

success_url = reverse_lazy('order_list')

并更改:

<form action="/order_list/" method="post">

致:

<form action="/add_order/" method="post">

注意:您正在使用硬编码 URL，不建议这样做。使用url模板标签。
