【问题描述】：

我正在尝试使用this method 自定义表单的输出。例如：

<div class="fieldWrapper">
     form.message.errors 
    <label for="id_message">Your message:</label>
     form.message 
</div>

如果我将表单呈现为form.as_p，一切正常，但单独呈现字段不起作用。

我有一些想要隐藏的字段，所以我尝试单独渲染每个字段。我试图隐藏的字段在模型类中具有null=True, blank=True 属性，因此不是必需的。

没有显示错误，而是刷新了页面并且没有更新数据。考虑到这些因素，我不确定我可能会错过什么。这是视图：

观点来自userena：

@secure_required
@permission_required_or_403('change_profile', (get_profile_model(), 'user__username', 'username'))
def profile_edit(request, username, edit_profile_form=EditProfileForm,
                 template_name='userena/profile_form.html', success_url=None,
                 extra_context=None, **kwargs):
"""
Edit profile.

Edits a profile selected by the supplied username. First checks
permissions if the user is allowed to edit this profile, if denied will
show a 404. When the profile is successfully edited will redirect to
``success_url``.

:param username:
Username of the user which profile should be edited.

:param edit_profile_form:

Form that is used to edit the profile. The :func:`EditProfileForm.save`
method of this form will be called when the form
:func:`EditProfileForm.is_valid`. Defaults to :class:`EditProfileForm`
from userena.

:param template_name:
String of the template that is used to render this view. Defaults to
``userena/edit_profile_form.html``.

:param success_url:
Named URL which will be passed on to a django ``reverse`` function after
the form is successfully saved. Defaults to the ``userena_detail`` url.

:param extra_context:
Dictionary containing variables that are passed on to the
``template_name`` template. ``form`` key will always be the form used
to edit the profile, and the ``profile`` key is always the edited
profile.

**Context**

``form``
Form that is used to alter the profile.

``profile``
Instance of the ``Profile`` that is edited.

    user = get_object_or_404(get_user_model(),

    if not extra_context: extra_context = dict()
    extra_context['form'] = form

                                            extra_context=extra_context)(request)

我包含了使用% include 'my-template.html' % 呈现表单的html。是什么阻止我更新配置文件对象？感谢您的任何想法！

【问题讨论】：

当您点击表单上的提交时，您的服务器日志会显示什么内容？

【参考方案1】：

尝试添加

form.errors

到您的模板某处查看是否有任何非字段错误！

我之前不止一次遇到过同样的问题 :)
