python - django1.9中发生IntegrityError

Question

我是 django 1.9 的新手，我正在尝试制作一个应用程序，但我遇到了这个错误，我不知道如何修复它。这是我的错误和代码。错误:

IntegrityError at /blogapp//post/

NOT NULL constraint failed: blogapp_blog.user_id

在 models.py 中:

from django.db import models
from django.conf import settings
from django.contrib.auth.models import User
class Blog(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    title = models.CharField(max_length=50)
    content = models.CharField(max_length=99999)
    date = models.DateTimeField(auto_now_add=True)
    def __unicode__(self):
        return self.title

在views.py中:

def post(request):
    form = BlogText()

    if request.method == 'POST':
        form = BlogText(request.POST.copy())
        if form.is_valid():
            data = form.cleaned_data
            title = data['title']
            content = data['content']
            if not Blog.objects.all().filter(title=title):
                blog = Blog.objects.create(title=title,content=content,date=timezone.now())
                return render(request,'blogapp/postok.html')
            else:
                return HttpResponse('The title is used')
    else:
        form = BlogText()
    return render(request,'blogapp/post.html',{'form':form})

我需要在views.py中添加这个吗？:

if request.user.is_authenticated():

有人请帮帮我。我觉得我在这方面真的很糟糕。

您收到此错误是因为user_id 不能为空:

NOT NULL constraint failed: blogapp_blog.user_id

您还需要添加用户:

blog = Blog.objects.create(title=title, content=content,
                           date=timezone.now(), user=request.user)

另请确保只有登录用户才能使用login_required访问此 View 。装饰器:

@login_required
def post(request):
    # your stuff here
