我正在使用void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
vec2 uv = fragCoord.xy / iResolution.xy;
uv -= 0.5;
uv *= vec2(iResolution.x/iResolution.y,1.0);
uv += 0.5;
float d = sdAxisAlignedRect(uv, vec2(0.3), vec2(0.7));
float m = 1.0 - abs(d)/0.1;
float s = sin(d*400.0) * 0.5 + 0.5;
fragColor = vec4(s*m*(-sign(d)*0.5+0.5),s*m*(sign(d)*0.5+0.5),0,1);
}
以及 @{
Layout = null;
}

和rails 4.1.8 gem连接到ruby 2.1.2p95。我已阅读此document但它并未提供我们如何将数据附加到文档的现有行中。此外，任何人都可以提供任何其他文档链接，它提供了从rails连接到mongo的广泛语法。
以下代码不会附加数据，而是会创建一个新行：
mongo-2.0.4代码：
mongo db v3.0.3插入以下行后：
mongo_con.find(:chatid => 5678).update_one('$set' => {:chat => 'this is are you'})
我想在前一行中追加这一行：
require 'mongo'
db = Mongo::Client.new([ '192.168.56.102:27017' ], :database => 'stackoverflow')
