The final hangup before this site goes to live beta and it is a big one
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?

Re: The final hangup before this site goes to live beta and it is a big one
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-%><br/> 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"-%><br/> 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.
