Django －－Form

1、不使用Form表单

获取前端数据方式

name = request.POST['name']

name = request.POST.get['name']

2、使用Form表单

def comment_post(request):
    try:
        comment_form = 
        if comment_form.is_valid():
            
            comment = Comment.objects.create(username=comment_form.cleaned_data["author"],
                                             email=comment_form.cleaned_data["email"],
                                             url=comment_form.cleaned_data["url"],
                                             content=comment_form.cleaned_data["comment"],
                                             article_id=comment_form.cleaned_data["article"],
                                             user=request.user if request.user.is_authenticated() else None)
            comment.save()
        else:
            return render(request, 'failure.html', {'reason': comment_form.errors})
    except Exception as e:
        logger.error(e)
    return redirect(request.META['HTTP_REFERER'])

3、Form表单验证

方式1、表单字段验证器

方式二：clean_filedname验证字段，针对某个字段进行验证

方式三：表单clean方法，可针对整个表单进行验证。
