Django - 表单不保存用户值

Question

我目前在我的网络应用程序的“myaccount.html”页面上有一个表单。

此表单呈现我想要的方式，但是由于某种原因我无法提交表单值以显示在 django 管理员中。

当用户点击“提交”时，页面刷新并且值保留在输入字段中。

我尝试了很多方法来解决这个问题，但没有运气。我以为我拥有一切，但也许我在某个地方遗漏了什么？

我还缺少什么来解决这个问题吗？

我是 Django 新手，因此非常感谢任何帮助。

谢谢！

Answer 1

您没有显示从父类继承的字段的字段或错误。没有它们，表格将无效。尝试添加 {{ form.errors }} 以查看验证错误的完整列表。

Answer 2

对于您的 form_valid 方法，请尝试以下方法：

def form_valid(self, form):
    user = form.save(commit=False) # object with form data
    user.save() # save object
    return redirect('success') # and then redirect to success view

对于您的模板，您还可以使用 for 循环来减少代码：

{% for field in form %}
 {{ field.label_tag }}
 {{ field }}
 {% if field.errors %}
    {{ field.errors }}
 {% endif %}
{% endfor %}
