users / views.py

Question

我目前在Web应用程序的“ myaccount.html”页面上有一个表单。

此表单呈现了我想要的样子，但是由于某种原因我无法提交表单值以使其出现在django管理员中。

当用户单击“提交”时，页面将刷新，并且值保留在输入字段中。

我尝试了许多方法来解决此问题，但没有运气。我以为我把所有东西都放在一起了，但是也许我在某处缺少了东西？

有什么我需要解决的问题吗？

我是Django的新手，非常感谢您的帮助。

谢谢！

Answer 1

您没有显示从父类继承的字段或字段的错误。没有它们，该表格将无效。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，请尝试以下操作：

if (i != lenStringOfLetters-1) {

对于模板，您还可以使用for循环来减少代码：

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

Django-表单不会保存用户值
