Django namespace, from form, get method of ajax and post method

django namespace

set namespace for urls

from django.urls import path
from . import views

app_name = 'news'
urlpatterns = [
    path('', views.news, name='news'),
    path('news_detail/<news_id>/', views.news_detail, name='news_detail'),
    path('news_list/', views.news_list, name='news_list'),
]

Use of namespaces

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <p>新闻首页</p>
	<!--  <p><a href="news_detail/">新闻详情页</a></p>  -->
    <p><a href="{% url 'news:news_detail' 1 %}">新闻详情页</a></p>
</body>
</html>

django的ajax

from form
-get method

    <from action="/text/" method="get">
        user: <input type="text">
        pwd: <input type="text">
        <input type="submit">
    </from>

verify:

def text_ajax(request):
    if request.method == 'GET':
        name = request.GET.get('name')
        pw = request.GET.get('pw')
        print(request.method)
        print(name)
        print(pw)

post needs to add csrftoken, everything else is the same

The use of ajax
in django has troubled me for a few days. The get method can be used directly, and the post also needs to obtain the csrftoken. Since I didn't pay much attention to the information displayed in the django console, I have been looking at the information of the browser. The error is 500, which is an internal server error. I thought it was unable to find the route. As a result, I checked the Internet for a few days, but there was no result. Today, I saw the console information by chance, and I realized that the scrftoken was not carried.

in urls

from django.urls import path
from . import views

app_name = 'text_ajax'
urlpatterns = [
    path('text/', views.text_ajax, name='text_ajax'),
]

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

    $('.btn').click(function () {

            url: '/text/text/',
            type: 'get',
