我为我的应用程序使用了bootstrap菜单.它看起来像这样: 但当我将窗口大小更改为更小时,它会消失 - 看起来像这样: 它大约约965px时消失(所以可能是979px).我试过这个解决方案,没有用.可能是我正在混合bootstrap 2和3？这是我的菜单代码:

<div class="navbar navbar-inverse navbar-fixed-top">
    <div class="navbar-inner">
        <div class="container">
            <a class="brand" href="/">Digrin</a>
            <div class="nav-collapse collapse">
                <ul class="nav">
                {{ request.path  }}
                    <li{% block nav_stocks %}{% endblock %}><a href="/stocks/">Stocks</a></li>

我在使用uwsgi和nginx设置服务器时遇到问题.这是我的uwsgi ini文件(和vassals中的符号链接):

我有一个奇怪的问题,没有想法可能是错的,所以也许在这里写它可以帮助我提出想法.或者有人可以帮助我:)

我有一个在牧场主运行的Django网站,过去几周我发现电子邮件无效.超时错误被提出.我使用mailgun.org作为SMTP服务器.

这是从牧场主容器控制台输出的:

/app/app # ipython
Python 2.7.14 (default, Dec 19 2017, 22:36:09)
Type "copyright", "credits" or "license" for more information.

IPython 5.5.0 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: from smtplib import SMTP

In [2]: smtp = SMTP(host='smtp.mailgun.org', port=587)

它只是挂起.添加超时当然会引发超时.

我猜想mailgun有问题.但是在本地运行相同图像上的相同代码(commit-hash匹配rancher容器上的代码).

docker run -ti registry.gitlab.com/namespace/app:commit-hash /bin/sh
/app/app # ipython …

我有一个 Django 网站，带有 model Event，可以说：

class Event(models.Model):
    home = models.ForeignKey('Team', related_name='%(class)s_home')
    away = models.ForeignKey('Team', related_name='%(class)s_away')
    ...

class Team(models.Model):
    name = models.CharField("team's name", max_length=100)

为此使用外键是一个坏主意，但无论如何，如何使其在 Django 管理页面中可用？
在管理编辑事件页面中，为此获取了大量外键：
http://127.0.0.1:8000/admin/event/event/116255/

它产生大量的选择，例如：
SELECT "event_team"."id", "event_team"."name" FROM "event_team" WHERE "event_team"."id" = 346;

页面就死了。我正在玩这些：

class EventAdmin(admin.ModelAdmin):
    list_display = ('id', 'home', 'away', 'date_game', 'sport', 'result')
    search_fields = ['home__name', 'away__name']
    list_select_related = (
        'home', 'away', 'league', 'sport', ...
    )

    def get_queryset(self, request):
        return super(EventAdmin, self).get_queryset(request).select_related(*self.list_select_related)
admin.site.register(Event, EventAdmin)

但没有运气。

不知道为什么,但我的typeahead.js远程自动完成停止工作.我没有更改任何关于typeahead.js的代码,但由于它被破坏了,我一定是错的.你能看看我的网站吗？我会创建jsfiddle,但多亏了Cross-Origin Request Blocked我无法包含我的依赖.
问题:
如果我输入"JN"或"AAP",这就是我得到的(建议是纯文本的):
此外,我想知道为什么自动完成在第三个字符输入后开始,而不是第一个(我使用minLength: 1).
我会将大部分代码粘贴到此处,因为我将来可能会更改我的网站.

我一直在使用openshift很长一段时间.由于letsencrypt处于测试阶段,我认为我试了一下.
我当前的设置:
www.digrin.com是我的openshift网址的别名 - digrin-digrincom.rhcloud.com
digrin.com标记指向wwwizer重定向服务174.129.25.170.
我已将ssl证书上传到openshift.它在域上运行良好www.digrin.com.但是,由于裸域digrin.com指向wwwizer.com,因此不使用https.我相信这是一个问题.我想要两个域(裸体和www变体)使用https.可能吗？我知道wwwizer有一些可能的高级计划,但如果可能的话我想要一个免费版本.
如果你不知道,我不能为裸域设置cname,所以我不得不使用A标签到wwwizer,因为openshift可能会改变IP地址.

我安装某些python软件包时遇到了麻烦，因为我有TLS 1.0版本。如何升级到TLS 1.2？

python -c "import urllib2; import json; print(json.loads(urllib2.urlopen('https://www.howsmyssl.com/a/check').read())['tls_version'])"

我试图升级openssl，但它没有升级LibreSSL。我记得一年前我遇到了一些与openssl的问题，我可能已经手动将其链接了，或者：:(

我无法使用我的ini文件在emperror模式下运行uwsgi.我安装了uwsgi sudo pip install uwsgi.

我不知道为什么我的cron运行20分钟而且终止了.在openshift中,如果你运行cron,它会在5分钟后被杀死.如果你用nohup运行,它会在20分钟后被杀死.
这是我在cron_daily上的错误日志.文件update_dave_list运行20分钟:

我在写一个简单的表格时遇到了问题.这是我表格的模型.

class UserStock(models.Model):
    amount = models.FloatField(default=0)
    date = models.DateTimeField('buy date')
    stockPrice = models.FloatField(default=0)
    user = models.ForeignKey(User)
    stock = models.ForeignKey(Stock)

这是我的forms.py文件

from django import forms
from datetime import date

class AddStockForm(forms.Form):
    stock = forms.CharField(max_length=10)
    amount = forms.FloatField(initial=0)
    #, initial=date.today, input_formats=settings.DATE_INPUT_FORMATS
    date = forms.DateField('buy date', initial=date.today)
    stockPrice = forms.FloatField(initial=0)

这是我提交表单数据的第一个版本.

@login_required(login_url='/login/')
def new_stock(request):
    if request.method == 'POST':
        form = AddStockForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data

            #dateForm = datetime.datetime.strptime(cd['date'],"%Y-%m-%d")
            userStock = UserStock(amount = cd['amount'], date=cd['date'], stockPrice = cd['StockPrice'])
            userStock.user = request.user
            stockForm = …

可能为时已晚，因为我完全不明白这个错误。我在models.py中创建了两个新类：

class SuggestionEmailSent(models.Model):
    user = models.OneToOneField(User, related_name='suggestion_sent')
    frequency = models.CharField(max_length=10, choices=EMAIL_FREQUENCY_CHOICES, default=EMAIL_FREQUENCY_CHOICES[0][0])
    date = models.DateField(default=timezone.now)
    class Meta:
        unique_together = ("user", "date")    

class SuggestionEmailContent(models.Model):
    percentage = models.IntegerField()
    buy_stock = models.ForeignKey('stocks.Stock', related_name='suggestion_email_buy_stock')
    sell_stock = models.ForeignKey('stocks.Stock', related_name='suggestion_email_sell_stock')
    portfolio = models.OneToOneField('portfolio.Portfolio', unique=True)
    suggestion_sent = models.ForeignKey(SuggestionEmailSent, related_name='contents')

然后我有一个代码：

try:
    content = user.suggestion_sent.contents.get(portfolio=portfolio)
    print content.sell_stock
except ObjectDoesNotExist: #mail not sent for this portfolio, send and save
    content, created = SuggestionEmailContent.objects.create(percentage=percentage,
         buy_stock=suggestion,
         sell_stock=rank,
         portfolio=portfolio,
         suggestion_sent=user.suggestion_sent)

这是错误回溯：Traceback（最近一次调用最后一次）：

  File "./test.py", line 49, in <module>
    send_suggestion_email(User.objects.get(id=1))
  File "/var/www/django/digrin/wsgi/digrin/suggestion/utils.py", line 192, …

对我来说,找出问题可能为时已晚.我有一个简单的形式forms.py:

class ImportPortfolioForm(forms.Form):
    file = forms.FileField(required=True)
    price_per_share = forms.BooleanField('Price per Share', required=False, initial=True,
                                   help_text="If not checked, total cost is expected in Price column.")

这是html:

<form method="post" action="" class="wide" class="form-horizontal" enctype="multipart/form-data">
    <div class="col-md-6">
    {% csrf_token %}
    {% bootstrap_form form %}
    <button type="submit" class="btn btn-primary">Import</button>
    </div>
</form>

这是views.py:

if request.method == 'POST':
    form = ImportPortfolioForm(request.POST, request.FILES)
    if form.is_valid():
        data = form.cleaned_data
        # work with file ...
else:
    form = ImportPortfolioForm()

如果我尝试加载表单网址,我收到错误:

TypeError: __init__() got multiple values for keyword …

我还没有找到足够好的答案，所以我在这里问。我有股息和股票模型。

class Dividend(models.Model):
    attributes...
    stock = models.ForeignKey(Stock)

我需要创建Queryset的副本，因为我想将带有一些额外值的红利传递给模板，并且我不希望将这些额外值插入数据库。

dividend_set = stock.dividend_set.all().order_by('date')
dividend_set.create(...)

我怎样才能做到这一点？上面的代码将在我的stock.dividend_set中创建数据。我是否必须使用Deepcopy或将queryset转换为list？还是有更优雅的方式？
