我尝试重新启动服务器时遇到错误.我不知道如何解决这个问题.

deploy@user:~$ sudo nginx -s reload
nginx: [emerg] unknown directive "passenger_root" in /etc/nginx/nginx.conf:66

我将这些行添加到nginx配置文件'/etc/nginx/nginx.conf'

passenger_root /home/deploy/.rvm/gems/ruby-2.0.0-p353/gems/passenger-4.0.37;
passenger_ruby /home/deploy/.rvm/gems/ruby-2.0.0-p353/wrappers/ruby;

您好我想知道如何使用Docker将POSTGIS连接到django.我有一个错误could not open extension control file "/usr/share/postgresql/10/extension/postgis.control": No such file or directory

嗨,我正在关注djangoproject网站上的教程,我在localhost上收到错误说:

Unknown parameters: TEMPLATE_DEBUG

我的settings.py看起来像这样:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'TEMPLATE_DEBUG':True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

我在TEMPLATE上添加了'TEMPLATE_DEBUG',否则我收到以下警告

?: (1_8.W001) The standalone TEMPLATE_* settings were deprecated in Django 1.8 and the TEMPLATES dictionary takes precedence. You must put the values of the following settings into your default TEMPLATES dict: TEMPLATE_DEBUG.

我的模板文件夹在我的应用程序中,即:

my_project_name/polls/templates/polls/index.html

我使用Rails并且每次我生成一个命令(即rails生成脚手架文章)

我在脚手架的末尾有这个输出:

〜/ Documents/programming/rails_book/beginning_rails_3/blog3_2_11 $ body:text published_at:datetime --skip-migration警告:root:无法打开文件'/etc/apt/sources.list.d/passenger.list'

我记得今天早上我通过intalling(passenger-install-apache2-module)遇到了乘客(doc)的一些问题

Create a file /etc/apt/sources.list.d/passenger.list and insert one of the following lines, depending on your distribution. 

我想知道删除此输出？

我想知道如何使用middleman console.这是一个简单的irb吗？我能用它做什么与简单的irb不同？

middleman console [options]         # Start an interactive console in the cont...

我有一些文章,我尝试做,Article.all但我有以下错误:

NameError: uninitialized constant Middleman::Application::MiddlemanApplication1::Article
    from (irb#1):1

我也有本地数据 /data/friends.json但Friend.all输出错误.

{
  "friends": [
    "Tom",
    "Dick",
    "Harry"
  ]
}

我看到Symbol.all_symbols输出了很多中间变量和函数,但我真的不知道如何使用中间人控制台.

我正在尝试使用这个gem:csv2json(0.3.0),我收到了一个错误.

在我的档案essaie.rb:

require 'csv2json'

File.open('essaie.csv', 'r') do |input|
    File.open('output.json', 'w') do |output|
        CSV2JSON.parse(input, output)
    end
end

Rails 4:我来自rails 3.2.x我有一个问题.如何在没有控制器的情况下使用Strong参数.

我有这个型号:

Track (the only one that has a Controller  )
  has_many :tracksegments, :dependent => :destroy
  has_many :points, :through => :tracksegments
Tracksegment
  belongs_to :track
  has_many :points, :dependent => :destroy
points
  belongs_to :tracksegment

Track是唯一一个拥有Controller的轨道,因此它具有一些强参数.

我想知道在哪里可以放置属于"tracksegment"和"points"的参数在Rails 3.x中它直接在模型中但在rails 4中我没有控制器.
