Django自定義表單模板

SuspiciousOperation at /signup/
ManagementForm data is missing or has been tampered.
Request Method: POST
Request URL:    http://localhost:8000/signup/
Django Version: 3.2.9
Exception Type: SuspiciousOperation
Exception Value:    
ManagementForm data is missing or has been tampered.
Exception Location: C:\Users\arund\Desktop\Code\Django\portfolio-project\venv\lib\site-packages\formtools\wizard\views.py, line 282, in post

我試圖通過為表單添加 2 個按鈕來更改我的模板，但出現此錯誤。它顯示兩個按鈕，但每次我單擊一個按鈕時，它都不會正確提交。我想根據按鈕單擊將模式中的 is_doctor 欄位設定為 false 或 true。

from django.contrib.auth import login, authenticate

    # try to get the cleaned data of step 1
    cleaned_data = wizard.get_cleaned_data_for_step('0') or {}
    # check if the field isDoctor was checked.
    return cleaned_data.get('is_doctor')== False

def process_data(form_list):
    form_data = [form.cleaned_data for form in form_list]
    print(form_data)
    return form_data

uj5u.com熱心網友回復：

您正在使用表單向導，但您的 html 表單中似乎缺少向導管理表單資料。

{% block content %}

  <form method="post">
    {% csrf_token %}
    <!-- A formwizard needs this form -->
    {{ wizard.management_form }}


    {% for field in form %}
      <p>
        {{ field.label_tag }}<br>
        {{ field }}
        {% if field.help_text %}
          <small style="color: grey">{{ field.help_text }}</small>
        {% endif %}
        {% for error in field.errors %}
          <p style="color: red">{{ error }}</p>
        {% endfor %}
      </p>
    {% endfor %}
    <button type="submit">Sign up</button>
    <a href="{% url 'login' %}">Log In</a>
  </form>
  
{% endblock %}
