Hello, I am pretty new to RoR and I am stuck on this problem and not even sure how to troubleshoot it. The issue is that my index.rhtml is not displaying any variables from my controller. Controller (versions_controller.rb) ==================================class VersionController < ApplicationController def index mydate = "20090521" end View (index.rhtml) =================<table> <td> <%= @mydate %> 1 </td></tr> </table> For some reason the view doesn''t see the variable. I also have a def query ... ... ... end in the same controller and it works fine (feeding query.rhtml without any issues). I can even put garbage in the controller such as "a;lskjdfj" and it doesn''t give me a compile error in the controller. Any help would be appreciated. Thanks, Marek -- Posted via http://www.ruby-forum.com/.

I did try that - but it still does not pass the value to the view... Is there something outside of the controller and view that could affect this?

I had tried that and numerous other things and it did not work. Also, how could I troubleshoot this? If I could see why the .rhtml is ignoring part of the .rb file, it would help...

Re: Fwd: Stuck on passing variable from controller to view
To check that the view is interpreting this you could try <%= "value is
#{@mydate}" %>. If you see the fixed text then it is just that @mydate
is
not getting setup for some reason. Possibly a typo that you just can''t
get
your eye on.
What do you mean by "I can even put garbage in the controller such as
"a;lskjdfj" and it
doesn''t give me a compile error in the controller."

What kind of typo could cause this? The odd thing is that I have a "def query" below it that is able to pass values to "query.rhtml" without any issues... As for your question, I have two rhtml files, index and query. If I put meaningless junk in "def query" I get the following interpretation error (as expected): undefined local variable or method `laksjdf'' for #<VersionController:0xf6993310> if I copy paste the same junk text into "def index", it does not produce an error (odd right?). This seems to indicate that version_controller.rb is not interpreting the code in "def index" for some reason, but is interpreting it in the "def query" which is directly below it. This is at least consistent with why it is not showing the value for @mydate. I don''t know enough about ruby to figure out what could cause this sort of behaviour.

Re: Fwd: Stuck on passing variable from controller to view
Post the contents of versions_controller.rb, there must be something wrong there. Strip out some of the unneeded stuff if it is more than a few tens of lines. If you do change it, make sure that it still fails, and that query still works.

The class should be VersionsController, not VersionController, though that may just be a typo in your post. 2009/5/22 Colin Law <clanlaw-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org>> Post the contents of versions_controller.rb, there must be something wrong > there.
