    <p>Program I'm making has a simple configuration file looking something like this.</p> <pre><code>@overlays = { :foo =&gt; "http://www.bar.com", :bar =&gt; nil, } </code></pre> <p>What I need to do is go through this hash and get the following output.</p> <pre><code>OverlayKey[0]='foo' OverlayVal[0]='http://www.bar.com' OverlayKey[1]='bar' OverlayVal[1]='nil' </code></pre> <p>In order to keep my configuration like I want it I need some fake index numbers. Would rather not add numbers into the hash, it would make the configuration look a bit ugly. So I been playing around with artificially generating the numbers during output.</p> <p>This is ugly but I"m just playing around with it currently.</p> <pre><code>def makenumbers @numbers = [] length = @overlays.length - 1 (0..length).each do |num| @numbers.push("#{num}") end end makenumbers @overlays.each do |key,val| @numbers.each do |num| puts "OverlayKey['#{num}']='#{key}'" puts "OverlayVal['#{num}']='#{val}'" end end </code></pre> <p>Which is giving me something like this.</p> <pre><code>OverlayKey['0']='foo' OverlayVal['0']='http://www.bar.com' OverlayKey['1']='foo' OverlayVal['1']='http://www.bar.com' OverlayKey['0']='bar' OverlayVal['0']='' OverlayKey['1']='bar' OverlayVal['1']='' </code></pre> <p>Understand why this doesn't give me the output I want, although after playing with it for a bit I'm not really sure how to do what I want without adding numbers into the hash during configuration. Sure this is pretty simple I just can't seem to wrap my head around it.</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.
