    <p>Greetings,</p> <p>Every time I make a change to a Sinatra app I'm working on and try to refresh the browser (located at <a href="http://localhost:4567/" rel="nofollow noreferrer">http://localhost:4567/</a>) the browser will refresh and, the console window seems to restart the WEB brick server. The problem is that the content in the browser window does not change. </p> <p>A friend of mine told me it was a shotgun issue and referred me to rtomayko's shotgun gem:</p> <p><a href="http://github.com/rtomayko/shotgun" rel="nofollow noreferrer">http://github.com/rtomayko/shotgun</a></p> <p>On this page I read that the shotgun gem would basically solve my problem, allowing the changes made to my app to show up in the browser window after I refresh it. So I installed the shotgun gem. The installation was successful. To activate the shotgun function you have to type <strong>shotgun</strong> before the file name. In this case my Sinatra app's file name is <strong>shortener.rb</strong></p> <p>When I type <strong>shotgun shortener.rb</strong> to run my Sinatra app I get this error:</p> <p><a href="http://lh6.ggpht.com/_83PkeFeVNNk/S-ymaYEgDUI/AAAAAAAAArE/rr7uJE3dRj4/shotgun_error.png" rel="nofollow noreferrer">alt text http://lh6.ggpht.com/_83PkeFeVNNk/S-ymaYEgDUI/AAAAAAAAArE/rr7uJE3dRj4/shotgun_error.png</a></p> <p>I should also mention that before testing the shotgun method out to see if it worked, I installed the mongrel <em>(I realize I should have checked to see if shotgun worked before doing this as installing mongrel has complicated this problem)</em>. So on top of getting the error message above I also get this pop up window from Ruby.exe</p> <p><a href="http://lh6.ggpht.com/_83PkeFeVNNk/S-ymaaWIZKI/AAAAAAAAArA/8qYCGUN8Wo4/msvcrt-ruby18.dll_error.png" rel="nofollow noreferrer">alt text http://lh6.ggpht.com/_83PkeFeVNNk/S-ymaaWIZKI/AAAAAAAAArA/8qYCGUN8Wo4/msvcrt-ruby18.dll_error.png</a></p> <p>I have no idea what <strong>msvcrt-ruby18.dll</strong> is but I know that installing either <strong>shotgun</strong> and/or <strong>mongrel</strong> created this problem.</p> <p>Where to go from here?</p> <p>Thanks, Adam</p>

    1. COI discovered that the shotgun gem is not working because it requires fork(2) which is not available on Windows. That solves that issue.

    2. COI would just like to say that in consulting with some developer friends, I have come to the conclusion that I will no longer attempt to develop in Ruby and Sinatra on Windows. I have installed Virtual Box and Ubuntu 10.4 on my Windows Vista 64 machine so I may create a virtual machine (VM) that will run Ubuntu Linux. Check out this blog post about how Joon You develops on his Windows machine using Virtual Box and Ubuntu: http://blog.rubyhead.com/2010/05/14/if-youre-using-windows/

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
