Question

我正在尝试使用具有相同“name”属性的多个字段来验证表单。

第一位用户的表格：

class BuyTicketFormEmail(forms.Form):
    email = forms.EmailField()
    first_name_customer = forms.CharField(max_length=191)
    last_name_customer = forms.CharField(max_length=191)

其他用户的表单

class UserForm(forms.Form):
    first_name_user = forms.CharField(max_length=191)
    last_name_user = forms.CharField(max_length=191)

表单：https://i.imgur.com/mTdaZvK.jpg 客户可以添加多个其他用户，我不知道确切的号码，都具有相同的名称。

在HTML中我只显示一个表单，我该如何验证？

Answer 1

我不在家，我是用智能手机写的，对不起，如果代码不是100％正确的话。但是你会得到大线。

对于视图：

def add_user(request):
    i = 1
    n = 5 #change it to the number of users you want
    all_users_forms = []
    while i < n+1 :
        one_user_form = UserForm()
        all_users_forms += one_user_form
        i += 1
    context = {'all_users_forms':all_users_forms}   
    template = 'form.html' #change it to your template name
    return render(request, template, context)

在模板中渲染你的表单

{% for form in all_users_forms %}
{{ form }}

我不知道确切的长度（N），但你的回答帮助我找到解决方案，谢谢

names = request.POST.getlist('first_name')
surnames = request.POST.getlist('last_name')
id = 0
for name in names:
    data = {
        'first_name': name,
        'last_name': surnames[id]
    }
    users_form = self.users_form_class(data)
    id += 1
    if users_form.is_valid():
        f_name = users_form.cleaned_data['first_name']
        l_name = users_form.cleaned_data['last_name']
    else:
        return HttpResponse('String is too long, or containts incorrect characters')

验证具有N个相同属性的表单
