Ok everyone. I appreciate your time if you are looking at this, as  
this site is being setup to assist veterans who are having trouble  
with the health care system through the VA. And as I said, we are  
pretty close at this point to going live beta so if you can help me  
over this hump it would be extremely appreciated.

We have a form setup that asks the user to select a date when  
treatment began and then when treatment ended. After that they fill  
out a free text field explaining what kind of problems they  
experienced during their treatment. Then they submit it.

After that you go to user stories to view the stories submitted by  
everyone. Except we are getting an error when we try to open this page  
The error is posted below, and also the code from the models and  
controllers and rhtml files. I REALLY would appreciate any help in  
resolving this, so that I can put it into open beta, and then get it  
out to hopefully help make the nation aware of what is going on within  
the VA healthcare system.

Thank you for your time,

Dave

P.S. if you spot the problem could you provide easy to understand  
steps to resolve it?

Hmmm… you’re getting that error because somehow, the @admission  
you’ve  
selected from the database does not have a treatment associated with it.  
It could be that you just have a leftover record in your system without  
a  
treatment.

You can overcome this several ways…

first, do a check in that partial

\<% unless @admission.treatment.nil? %\>  
date: \<%=admission.treatment.treatment\_start-%\>  
  
story: \<%=admission.treatment.description-%\>  
\<% end %\>

Or you can take the lazy (but as I understand it, expensive) way out and  
just do  
date: \<%=admission.treatment.treatment\_start rescue “No start  
date”-%\>  
  
story: \<%=admission.treatment.description rescue “no story”-%\>

I’m going to go out on a limb here and say that you have unit tests in  
place  
to ensure that your associations between treatments and admissions are  
working… so I bet it has something to do with your data.

Brian,

Thank you so much, I am now able to view that page, and start moving  
towards final completion. I may push it out to open beta tonight so  
that the rails newsgroup can view it and give some feedback.

Thank you,

Dave
