Django －－Form

1、不使用Form表單

獲取前端數據方式

name = request.POST['name']

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

2、使用Form表單

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表單驗證

方式1、表單字段驗證器

方式二：clean_filedname驗證字段，針對某個字段進行驗證

方式三：表單clean方法，可針對整個表單進行驗證。
