    title = models.CharField(max_length=100)
    cover = models.ImageField(upload_to='blog_cover/')
    description = models.CharField(max_length=200)
    text = models.TextField()
    author = models.ForeignKey(get_user_model(), on_delete=models.CASCADE)
    active = models.BooleanField(default=False)

    date_create = models.DateField(auto_now_add=True)
    date_modified = models.DateField(auto_now=True)

    def __str__(self):
        return f'{self.title} : {self.author}'

    def get_absolute_url(self):
        return reverse('blog_detail', args=[self.id])

when I submit my form data don't save I want author auto quantification当我提交我的表单数据时不保存我想要作者自动量化

if blog_form.is_valid():
            new_form = blog_form.save(commit=False)
            new_form.author = request.user
            new_form.save()
            return redirect('blog_list')
else:
     print('bug is here')

I tried that and printed bug is here (when try from admin panel everything is right)我试过了，打印的错误在这里（当从管理面板尝试时，一切都是正确的）

In Your Blog Model have ImageField() so you need to pass request.FILES and also need to add enctype="multipart/form-data" in HTML form like this在你的Blog Model 中有 ImageField ImageField()所以你需要传递 request.FILES 并且还需要像这样在 HTML 中添加enctype="multipart/form-data"

views.py视图.py

def create_blog_view(request):
    if request.method == 'POST':
        blog_form = BlogForm(request.POST,request.FILES)
        if blog_form.is_valid():
            new_form = blog_form.save(commit=False)
            new_form.author = request.user
            new_form.save()
            return redirect('blog_list')
        else:
            print('its bog')
    else:
        blog_form = BlogForm()

    return render(request, 'pages/create_blog.html', context={
        'form': blog_form
    })

HTML form HTML表格
