    <p>I referred to <a href="https://github.com/shairontoledo/rghost-barcode/wiki/82-Barcodes" rel="nofollow noreferrer">here</a> and ran the following code in ruby:</p> <pre><code>require 'rghost' require 'rghost_barcode' doc=RGhost::Document.new doc.barcode_rationalizedCodabar('515893649655',{:text=&gt;{:size=&gt;8}, :enable=&gt;[:text, :checkintext, :check]}) doc.render :pdf, :resolution =&gt; 300, :filename =&gt; "barcode.pdf" </code></pre> <p>Below is the generated barcode:</p> <p><img src="https://i.stack.imgur.com/KONMq.png" alt="enter image description here"></p> <p><strong>The problem:</strong> I was not able to read this barcode with my barcode reader, and this barcode looks different from the one generated with online free barcode generator <a href="http://www.racoindustries.com/barcodegenerator/1d/codabar.aspx" rel="nofollow noreferrer">here</a>: <img src="https://i.stack.imgur.com/UZV9e.jpg" alt="enter image description here"></p> <p>You may notice the difference in the very first bars, where red rectangle.</p> <p>I thought maybe this is because I was generating "rationalizedCodabar". But the article <a href="https://code.google.com/p/postscriptbarcode/wiki/RationalizedCodabar" rel="nofollow noreferrer">here</a> says that it is the same as "Codabar".</p> <p><strong>Is there anyone who ever tried codabar generation successfully with ruby with whatever gem?</strong></p> <p>In general, I'm looking for an established barcode generator for Code39 and Codabar to generate barcodes within from RoR application.</p> <p>I'm aware of the "barby" gem, but it seems it doesn't generate Codabar barcodes...</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.
