I am getting an array with a single element in it, ["http://i.foobar.com/This-Is-The-Remainder-Of-The-Link.jpg"] and I'm trying to render it as just the URL to display an image. Any thoughts on the best way to do this? Currently when I render it in HTML I get ["http://i.foobar.com/This-Is-The-Remainder-Of-The-Link.jpg"]
我得到了一个数组，其中只有一个元素[“http://i.foobar.com/this - is- the - ever - of - link.jpg”]，我试图将它呈现为显示图像的URL。有什么好办法吗?目前，当我在HTML中渲染它时，我就得到了[" http://i.foobar.com/this - is- the - only - link.jpg"]

You should just be able to pull the first element. You can do this by doing the following.

a = ['http://someurl.com/somepath']
a.first

a = ['http://someurl.com/somepath']
