Question

我想更改以下HTML表单：

@transaction.atomic
def Register(request):
    if request.method == "POST":
        fname = request.POST['first_name']
        lname = request.POST['last_name']

        mobile = request.POST['mobile']
        """This section replaces multiple characters with blank value
        so that the mobile number has nothing except numeric values
        """
        rep = ['+', '-', ' ', '.']
        for i in rep:
            mobile = mobile.replace(i, '')

        company = request.POST['company']
        email = request.POST['email']

        u = User.objects.create_user(mobile, email, '1234', first_name=fname, last_name=lname)
        u.save()

        p = UserProfile.objects.create(user=u, company=company, mobile=mobile)
        p.save()

        return HttpResponse("Registration complete! Please head over to the <a href='/login/'>login page</a> to start using your SMS panel.")

    return render(request, "message/register.html", {})

进入Django表单主要是因为我需要学习如何使用它们，我还需要在注册完成之前填写所有字段，我不想要任何可选字段。以下是我从文档中提出的内容。

views.py

@transaction.atomic
def Register(request):
    if request.method == "POST":
        form = RegisterForm(request.POST)
        if form.is_valid():
            # I guess this is where I need help. Thanks.
    else:
        form = RegisterForm()
    return render(request, "message/register.html", {'form': form})

register.html

<form method="post" action="">
    {% csrf_token %}
    {{ form }}

    <input type="submit" value="Register"/>
</form>

Answer 1

在if form.is_valid() == True django创建了clean_data方法之后，您可以使用该方法将已清理的表单数据调用到您的视图中。

你可能想要这样的东西：

def Register(request):
if request.method == "POST":
    form = RegisterForm(request.POST)
    if form.is_valid():
        fname = form.cleaned_data.get('first_name')
        lname = form.cleaned_data.get('last_name')

https://docs.djangoproject.com/en/1.8/ref/forms/api/#django.forms.Form.is_valid

你的Form对象在forms.py中的含义是什么？

Answer 2

您可以创建表单RegisterForm，并将移动广告的清算过程添加到clean_mobile中的forms.py功能。然后在views.py中，您可以使用form.cleaned_data词典访问所有表单数据。

您可以执行以下操作：

<强> forms.py

from django import forms

class RegisterForm(forms.Form):

    first_name = forms.CharField(max_length=100)
    last_name = forms.CharField(max_length=100)
    mobile = forms.CharField()
    company = forms.CharField(max_length=100)
    email = forms.EmailField()

    def clean_mobile(self):
        mobile = self.cleaned_data['mobile']
        rep = ['+', '-', ' ', '.']
        for i in rep:
            mobile = mobile.replace(i, '')
        return mobile

<强> views.py

@transaction.atomic
def Register(request):
    if request.method == "POST":
        form = RegisterForm(request.POST)
        if form.is_valid():
            u = User.objects.create_user(form.cleaned_data['mobile'], form.cleaned_data['email'], '1234', first_name=form.cleaned_data['first_name'], last_name=form.cleaned_data['last_name'])
            u.save()

            p = UserProfile.objects.create(user=u, company=form.cleaned_data['company'], mobile=form.cleaned_data['mobile'])
            p.save()

            return HttpResponse("Registration complete! Please head over to the <a href='/login/'>login page</a> to start using your SMS panel.")
    else:
        form = RegisterForm()
        return render(request, "message/register.html", {'form': form})

如何将这个常规html表单更改为django表单？
