5,428 PointsTroubleshooting Help with Rails and Forms and Alerts
tl,dr: Having problems displaying :alerts correctly, need help finding where the problem is and fixing it.
I am bumbling my way through this: http://teamtreehouse.com/library/programming/build-a-simple-ruby-on-rails-application/designing-urls/refactoring-the-flash-code
and so far, haven't had any serious errors. However, as I'm watching the video I think to myself, maybe I should test that the :alert messages are coming through correctly.
I goto the login page and enter incorrect information, then hit login, but nothing happens. The page refreshes (doesn't let me login) but doesn't seem to display any errors. This is odd as when I login, the :notice displays correctly.
So, I think the :alert message is either not getting generated, or getting lost in a refresh. But how do I track this problem down?
Here is what the console says:

ps, i'm trying to display the console output in code form but it doesn't seem to work. I did the 4 space indent, but didn't seem to have an effect.
Help?

5,428 Pointsps, as a follow up for any fruitful searches, here is the answer:
I had this:
<% if flash[:notice] %>
<div class="alert alert-success">
<button type="button" class="close" data-dismiss="alert">x</button>
<%= flash[:notice] %>
</div>
<% end %>
It should be this:
<% flash.each do |type, message| %>
<div class="alert <%= flash_class type %>" >
<button type="button" class="close" data-dismiss="alert">x</button>
<%= message %>
</div>
<% end %>

Treehouse Guest TeacherCan you paste your app/views/layouts/application.html.erb file?

Treehouse Guest TeacherWilliam, I'd like to troubleshoot your code on this one. Can you possibly email it to help@teamtreehouse.com?
william kenny
5,428 Pointsemail sent! I just 7zipped the whole directory and sent it.
Thanks again for all the help!!
william kenny
5,428 PointsThat fixed the error. note to self, save in sublime otherwise your changes won't actually be changes!!

Brandon Rodgers
1,219 PointsSame here. I didn't even think to check until reading your response. Thanks! :)
Derek Saunders
5,167 PointsI have the same exact thing typed in and it gives me an error when I refresh my browser, it gives me a syntax error even though it is exactly what Jim typed in. I'm a little confused.
william kenny
5,428 PointsFirst, make sure that when you edit the file you save the file. I had that problem with sublime and it caused me lots of troubles.
Snytax errors are usually related to dropped closers or something like that. If your code references a line (it's been a while since i've messed with Ruby) can you post the code around that line?
Derek Saunders
5,167 Pointsthe only problem is that it doesn't reference a line
Jason Seifer
Treehouse Guest TeacherWhat does it say Derek Saunders?
Derek Saunders
5,167 Pointswilliam kenny I figured it out, in the application_helper.rb I just realized I forgot to end the def flash_class(type) I didn't realize it needed three end tags.
Derek Saunders
5,167 PointsJason Seifer thank you for asking! I figured it out just now haha. :)
william kenny
5,428 PointsNot a problem. That stuff drives me CRAZY! I can't tell you how many hours I've spent in other languages looking for the one line that I forgot to add a ;
