萌新求救!Django 做出来的网页url异常

我才学习制作了一个小的网页(此时路径是:http://127.0.0.1:8000/index/)![图片说明](https://img-ask.csdn.net/upload/201907/11/1562841009_226257.png)
,主要目的是向mysql数据库传输一个图片一个文件已经图片的图片名字,在选择完文件点提交后,就变成http://127.0.0.1:8000/views/了,并且报404错误,![图片说明](https://img-ask.csdn.net/upload/201907/11/1562840959_604996.png) 如何才能返回一个正常的网页,比如:index2.html。然后图片,文件也能上传到mysql。
views.py

from django.shortcuts import render
from myapp import models
from myapp.forms import PersonForm
# Create your views here.

def index(request):
    if request.method == 'POST':
        form =PersonForm(request.POST, request.FILES)
        pic1 = form.cleaned_data['pic1']
        name1 = form.cleaned_data['name1']
        label1 = form.cleaned_data['label1']
        models.db_boxs.objects.create(pic=pic1,name=name1,label=label1)
        return HttpResponse('regist success')
    if request.method == 'GET':
        return render(request,'index.html',{'form':PersonForm()})

    return render(request,'index.html',{'form':PersonForm()})

url.py

from django.contrib import admin
from django.urls import path
from myapp import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index)

views.py中最后一行的缩进是不是有问题,还有get和post的方法也可以用路径表示

# django2.0 如何调用在自带数据库sqlite3中新建立数据表实现来登录功能! ![图片说明](https://img-ask.csdn.net/upload/202001/07/1578408166_548149.jpg) 如图:新注册了一个app,然后在Django自带的sqlite3数据库中新建立了三个表,要调用“用户信息表”来实现登录功能,请问代码怎样写呀,求解!!!!
django中重写logging.Handle的emit,在里面实现日志的保存,但是在配置时一直报错,好像不能配置自定义的handlers
现在common的view下写了一个MyHandle类,重写emit方法 ``` class MyHandle(logging.Handler): """ 输出日志到队列 """ def emit(self, record): insert_logging.apply_async(args=[self.format(record)], queue=settings.RABBITMQ_QUEUE) ``` 此代码放在celery文件中,想通过celery来实现日志写入队列,之后再做处理 ![图片说明](https://img-ask.csdn.net/upload/202001/19/1579415564_177923.jpg) 但是我的消费者写在tasks文件中 然后再配置中加上handle,保证在每次访问的时候都会写入到队列 ![图片说明](https://img-ask.csdn.net/upload/202001/19/1579415680_323635.jpg) 结果在启动的时候就会报错,app没加载,因为tasks里面会加载到一些模型类等等。 最大的问题就是如果自定义了Handle,不知道这个handle该如何配置,才能不会在项目启动时发生冲突 ![图片说明](https://img-ask.csdn.net/upload/202001/19/1579415103_30076.png) 上图是django的配置,里面是自定义了一个handle

在HTML中使用标签a href="url"跳转时,为什么第一次会正常跳转,返回后再点击就会自动下载一个空文件而不跳转,文件名是链接中'?'前'/'后的一串,但是右键复制链接地址还是正确的链接,应该是django的问题因为我仅仅在HTML中没有问题,放在django下就不行了,请问大神们这是为什么啊??

volatile 与 synchronize 详解
Java支持多个线程同时访问一个对象或者对象的成员变量,由于每个线程可以拥有这个变量的拷贝(虽然对象以及成员变量分配的内存是在共享内存中的,但是每个执行的线程还是可以拥有一份拷贝,这样做的目的是加速程序的执行,这是现代多核处理器的一个显著特性),所以程序在执行过程中,一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段(成员变量),就是告知程序任何对该变量...
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
