我没有收到任何错误，但Django表单中的数据无法保存

Question

使用Django表单点击“提交”按钮时我没有数据

from django.shortcuts import render, get_object_or_404
from django.http import Http404


from .forms import BlogPostForm
from .models import BlogPost



def blog_post_list_view(request):
    qs = BlogPost.objects.all()
    template_name = 'blog/list.html'
    context = {'object_list': qs}
    return render(request, template_name, context)


def blog_post_create_view(request):
    template_name = 'form.html'
    form = BlogPostForm(request.POST or None)
    if form.is_valid():
        print(form.cleaned_data)
    context = {'form': form}
    return render(request, template_name, context)

这是forms.py 从Django导入表单中获取

class BlogPostForm(forms.Form):
    title = forms.CharField()
    slug  = forms.SlugField()
    content = forms.CharField(widget=forms.Textarea)

我希望输入的数据可以在控制台上打印出来，以便查看是否可以保存数据
