我在pipenvdocker 容器内使用。我尝试安装一个包，发现安装成功（被添加到 Pipfile 中），但锁定一直失败。一切都很好，直到昨天。这是错误：

我正在为我正在开发的 Django 项目进行身份验证。由于某些原因，我收到错误“Reverse for 'password_reset_done' not found. 'password_reset_done' is not a valid view function or pattern name.我将所有身份验证都放在accounts应用程序中”。

这是基本文件的内容urls.py：

from django.contrib import admin
from django.urls import path, include
from accounts import urls as accounts_urls
from core import urls as core_urls
from core import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.home, name='home'),
    path('accounts/', include(accounts_urls, namespace='accounts')),
    path('core/', include(core_urls, namespace='core')),
]

这是文件的内容urls.py（在帐户应用程序中）：

from django.urls import path, reverse_lazy
from django.contrib.auth import views as auth_views

我有以下 ModelForm：

class IssueProcessForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(IssueProcessForm, self).__init__(*args, **kwargs)

        self.fields['number'].disabled = True
        self.fields['title'].disabled = True
        self.fields['body'].disabled = True

        self.fields['body'].widget = forms.Textarea(
            attrs={
                'cols': 50
            }
        )

    class Meta:
        model = Issue
        fields = (
            'number', 'title', 'body', 'price'
        )

我想用视图中的数据预先填充字段number、title和body，呈现表单，并确保显示与字段对应的值，同时禁用这些字段，以便用户不会更改值。我希望该price字段是用户触摸的唯一内容，并且当单击保存按钮时，我希望将所有内容保存到数据库中。我尝试了以下方法：

def issue_process(request, repo_name, issue_number):
    get_issue_number = request.session.get('issue_number_{}'.format(issue_number))
    get_issue_title = request.session.get('issue_number_{}_title'.format(issue_number))
    get_issue_body = request.session.get('issue_number_{}_body'.format(issue_number))

    if request.method == 'POST':
        form = IssueProcessForm(request.POST)
        if form.is_valid():
            issue = form.save(commit=False)
            issue.number = get_issue_number
            issue.title = …

我正在编写一个程序，该程序管理有关全球变暖的五个问题的多项选择测验，并计算正确答案的数量。我首先创建了词典字典，例如：

questions = \
{
    "What is the global warming controversy about?": {
        "A": "the public debate over whether global warming is occuring",
        "B": "how much global warming has occured in modern times",
        "C": "what global warming has caused",
        "D": "all of the above"
    },
    "What movie was used to publicize the controversial issue of global warming?": {
        "A": "the bitter truth",
        "B": "destruction of mankind",
        "C": "the inconvenient truth",
        "D": "the depletion"
    },
