    <p>I'm trying to parse a URI that has brackets - [ and ] - in it. I have tried to parse this directly with URI.parse but the brackets cause this to fail. I therefore tried to encode the URI with CGI::escape which takes care of the brackets but when I try to parse this encoded URI with URI.parse it doesn't seem to recognise it as a URI and puts the entire URI into the path object.</p> <p>To demonstrate in an irb session;</p> <pre><code>irb(main):001:0&gt; require 'uri' =&gt; true irb(main):002:0&gt; require 'cgi' =&gt; true irb(main):003:0&gt; name = "http://www.website.com/dir1/dir[2]/file.txt" =&gt; "http://www.website.com/dir1/dir[2]/file.txt" irb(main):004:0&gt; encoded_name = CGI::escape(name) =&gt; "http%3A%2F%2Fwww.website.com%2Fdir1%2Fdir%5B2%5D%2Ffile.txt" irb(main):005:0&gt; parsed_name = URI.parse(encoded_name) =&gt; #&lt;URI::Generic:0x00000001e8f520 URL:http%3A%2F%2Fwww.website.com%2Fdir1%2Fdir%5B2%5D%2Ffile.txt&gt; irb(main):006:0&gt; parsed_name.scheme =&gt; nil irb(main):007:0&gt; parsed_name.host =&gt; nil irb(main):008:0&gt; parsed_name.path =&gt; "http%3A%2F%2Fwww.website.com%2Fdir1%2Fdir%5B2%5D%2Ffile.txt" irb(main):009:0&gt; URI.split(encoded_name) =&gt; [nil, nil, nil, nil, nil, "http%3A%2F%2Fwww.website.com%2Fdir1%2Fdir%5B2%5D%2Ffile.txt", nil, nil, nil] </code></pre> <p>Anyway, my work around at the moment is the following ugly, but effective, hack</p> <pre><code>encoded_name = name.gsub(/\[/,"%5B").gsub(/\]/,"%5D") </code></pre> <p>Parsing this with URI.parse produces the desired result but won't cope if other strange characters find their way into my URIs. So my question is, is there a solid way of doing this that won't fall down?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
