Question

以下代码有问题。当我在下面登录并尝试提交create.html模板时，它会将我重定向到主页（通过视图中的home函数，并且记录未保存在数据库中）。当我删除@login_required并直接导航到/ products / create时，记录将保存在数据库中。我很困惑为什么会这样。任何帮助将不胜感激

我删除了（@login_required）并直接导航到/ products / create，它运行良好。但是，每当我登录然后使用/ products / create时，记录都不会保存在数据库中

Create.html

{%extends 'base.html'%}

{%block content%}

{%if error%}
{{error}}
{%endif%}

<h2> Create </h2>
{% csrf_token %}
<form  action="create"  method="POST"  enctype="multipart/form-data">

{% csrf_token %}
Title:
<br/>
<input type="text"  name = "title"/>
<br/><br/> 
Body:
<br/>
<input type="textbox" name = "body"/>
<br/><br/>
URL:
<br/>
<input type="text" name = "url"/>
<br/><br/> 
<input type="submit" class = "btn btn-primary" value = "Add Product"/>

</form>
{%endblock%}

供参考

models.py

from django.db import models
from django.contrib.auth.models import User

class Product(models.Model):
    title = models.CharField(max_length=255)
    pub_date = models.DateTimeField()
    body = models.TextField()
    url = models.TextField()
    image = models.ImageField(upload_to='images/')
    icon = models.ImageField(upload_to='images/')
    votes_total = models.IntegerField(default=1)

    def __str__(self):
        return self.title

    def summary(self):
        return self.body[:100]

    def pub_date_pretty(self):
        return self.pub_date.strftime('%b %e %Y')

*登录功能*

def login(request):
    if request.method == 'POST':
       user =     auth.authenticate(username=request.POST['username'],password=request.POST['password'])
        if user is not None:
            auth.login(request,user)
            return redirect('home')
        else:
            return render(request,'accounts/login.html',{'error':'incorrect username or password'})

    else:
           return render(request,'accounts/login.html')

Django @login_required重定向到首页
