如何從 html 表單中獲取cleaned_data？

Question

我有 django 應用程序，該應用程序帶有基於 class 的視圖和用 html 編寫的表單：

<form method="post" action="{% url 'personal-account' %}">
            {% csrf_token %}
            <div class="page slide-page">
              <div class="field">
                <input type="text" placeholder="First name" class="input_1" name="first_name" size="1" value="{{ data.first_name }}">
                <input type="text" placeholder="Last Name" class="input_2" name="last_name" size="1" value="{{ data.last_name }}">
              </div>
              <div class="middle">
                <input type="text" placeholder="Username" class="input_3" name="username" size="1" value="{{ data.username }}">
                <input type="text" placeholder="Email" class="input_6" name="email" size="1" value="{{ data.email }}">
              </div>
              <div class="last">
                <input type="password" placeholder="Password" class="input_4" name="password" size="1" value="{{ data.password }}">
                <input type="password" placeholder="Confirm" class="input_5" name="confirm_password" size="1"  value="{{ data.confirm_password }}">
              </div>
              <div class="field">
                <button type="submit" class="submit-btn">Submit</button>
              </div>
            </div>
          </form>

看法

class PersonalSignup(View):
    def post(self, request):
        
        return render(request, 'authentication/personal_signup.html')
    def get(self, request):
        return render(request, 'authentication/personal_signup.html')

現在我想用cleaned_data從輸入（first_name，last_name ...）中獲取所有值。

Answer 1

首先，您需要在 forms.py 中創建一個表單。 像這樣：

class PersonalSignupForm(forms.Form):
    first_name=forms.CharField(max_length=255)
    last_name=forms.CharField(max_length=255)
    username=forms.CharField(max_length=255)
    password=forms.CharField(max_length=255)
    confirm_password=forms.CharField(max_length=255)

然后在 viwe 中這樣做：

from .forms impory PersonalSignupForm

class PersonalSignup(View):

     def get(self, request):
         form=PersonalSignupForm()
             return render(request, 'authentication/personal_signup.html',context={'form':form})

     def post(self, request):
        form=PersonalSignupForm(request.POST)
        if form.is_valid():
           first_name=form.cleaned_data.get('first_name')
           last_name=form.cleaned_data.get('last_name')
           username=form.cleaned_data.get('username')
           password=form.cleaned_data.get('password')
           return render(request, 'authentication/personal_signup.html')

Answer 2

在您的視圖中，您可以從 request.POST（返回字典）中獲取信息，如下所示：

if request.method == 'POST':
    first_name = request.POST['first_name']
