当使用capistrano部署app时,在production.log中会出现错误.

这是我正在使用的Gemfile.lock.

我想强制一个sankey图的分支在顶部.

而不是像这样的图:

想要生成图表,其中节点1,2,7,15,10和14始终位于顶部:

链接到当前代码的小提琴:http://jsfiddle.net/w5jfp9t0/1/

var margin = {top: 1, right: 1, bottom: 6, left: 1};
var width = 1052 - margin.left - margin.right;
var height = 500 - margin.top - margin.bottom;

var formatNumber = d3.format(",.0f"),
    format = function(d) { return formatNumber(d); },
    color = d3.scale.category20();

var svg = d3.select("#chart_sankey").append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
  .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");

var sankey = d3.sankey()
                         .nodeWidth(35) …

有没有办法用image magick命令identify或其他命令返回图像配置文件？

例如,我有一个图像kitchen.jpg.此图片具有Euroscale Coated v2的个人资料.我可以通过跑步看到identify -verbose kitchen.jpg.

  Profile-xmp: 7501 bytes

...

我试过但identify -verbose wohnbereih_original.tif | grep 'Profile-icc'它返回Profile-icc: 557164 bytes但我现在不知道如何返回下一行.

我在单元格中有以下功能.它从其他单元格中读取日期,而不是计算年龄并以"3周5天"的格式进行转换

=INT((TODAY()-D19)/7)&" weeks, "&(TODAY()-D19-(INT((TODAY()-D19)/7)*7))&" days"

有用.

现在我想将这个长字符串替换为一个简单的函数:

=AGEINWEEKS(D19)

我怎样才能做到这一点？

我已经尝试在脚本编辑器中编写此脚本

function ageInWeeks(from_date) {
  return SpreadsheetApp.getActiveSheet().getRange("D16").setFormula('=ROUND((TODAY()-D16)/7)&" weeks, "&(TODAY()-D16-(ROUND((TODAY()-D16)/7)*7))&" days"');
}

但它返回错误

错误:您无权调用setFormula(第3行,文件"Code")

先感谢您!

如何更改rails表单助手的默认生成代码？

码...

<%= f.text_field :title, class: 'inputbox' %>

... ...产生

<input id="post_title" name="post[title]" class="inputbox" type="text">

...但我想默认情况下没有类参数的text_field生成代码.

我正在使用rails 3.2.

如何扫描之间的所有字符串*|和|*文本一样

Today is *|date|*. Weather is *|weather_description|*.

使用Ruby "string...".scan(...).

我想获得一系列的比赛:["date", "weather_description"].
