我的独角兽服务器运行正常,但已停止工作,我无法弄清楚如何重新启动它.
2011/04/18 15:23:42 [error] 11907#0: *4 connect() to unix:/tmp/sockets/unicorn.sock failed (111: Connection refused) while connecting to upstream, client: 71.131.237.122, server: localhost, request: "GET / HTTP/1.1", upstream: "http://unix:/tmp/sockets/unicorn.sock:/", host: "tacitus"
我的配置文件位于:https://gist.github.com/926006
任何有关我的故障排除选项应该是什么的帮助将不胜感激.
最好,

我在MATLAB中玩OOP,我有以下构造函数:
function obj = Squadron(num_fighters, num_targets, time_steps)
if nargin == 0
num_targets = 100;
time_steps = 100;
num_fighters = 10;
end
obj.num_shooters = num_fighters;
for iShooter = 1:obj.num_shooters
a(iShooter) = Shooter(num_targets, time_steps);
end
obj.ShooterArray = a;
obj.current_detections = zeros(num_fighters, num_targets);
end
那个临时变量'a'闻起来很可怕.有没有更好的方法来初始化一个对象数组,我希望有一个推/弹方法.我相信有更好的方法可以做到这一点.
我试图让mongoid保存关联,但我只能让一方工作.如果我有以下测试.
test "should add a user as a follower when a user follows the group" do
@cali_group.followers = []
@user1.followed_groups << @cali_group
assert_equal 1, @user1.followed_groups.count
assert_equal 1, @cali_group.followers.count
end
哪个失败了,因为@ cali_group.followers是[].我已经使用了一段时间,尝试过@cali_group.reload.但看起来在我的代码中执行此操作的唯一方法是使用连接的两端,即@cali_group.followers << @user1.如果必须的话,我可以在我的代码中这样做.
polco_group和用户的模型如下:https://gist.github.com/1195048
完整的测试代码在这里:https://gist.github.com/1195052
我有一个工厂,我在其中定义了一个位置factories/locations.rb.我正在使用Mongoid和Rails 3.1.1和ruby 1.9.3.
FactoryGirl.define do
factory :location do
name Faker::Name.name
description "Down by the river"
end
end
然后我想定义一个属于一个位置的健身营(因此具有location_id属性).
FactoryGirl.define do
factory :fitness_camp do
title "Parkour"
association :location_id, :factory => :location
end
end
这是有效的,但是,这是我的黑客攻击的结果,而不是我在文档中读到的.从入门指南(https://github.com/thoughtbot/factory_girl/blob/master/GETTING_STARTED.md)看来,这应该是这样简单:
factory :fitness_camp do
title "Parkour"
location
end
我错过了什么吗？这是否表示我的模型可能配置不正确？
谢谢!

这可能吗？如果没有显式任务,则无法正确构建任务列表.

我经常发现自己试图搜索单元格数组,就像我想用sql查询搜索数据库一样.在这种情况下,我有一些军事基地(bases.shp)
bases = shaperead('us-military-bases.shp')
然后我想过滤掉形状文件以获得空军基地,就像这样regexp({bases.FAC_NAME}','Air Force').但我得到的输出是相当麻烦的:
[]
[]
[ 4]
[]
[]
[ 9]
[]
我确信过滤单元格数组或shapefile很常见,必须有一些好的做法.感谢您的任何见解.
我也在尝试这样的事情:
trif = arrayfun(@(x)regexp(x.FAC_NAME,'Griff','match'),af_bases)
我想模拟/存根:
@the_bill = GovKit::OpenCongress::Bill.find_by_idents("112-s368").first

"".content? => false # same as .empty?

具体来说,content?如果有人可以在那里阅读,那么会通过.我将修补String类以使用正则表达式执行此操作.
"\n\t\n\n".gsub(/[\n|\t]/,'').empty?
这让我很接近,但我可能会重新发明轮子,并希望有一个更完整的解决方案.
