hiya,

trying to work this out to build a dynamic sidebar,

i’ve got the sidebar in a partial, now wondering how to get different  
elements to hide for certain actions…

e.g.

\<% if action = ‘about’ %\>  
about logo  
\<% end %\>

any ideas how you can run conditional parts based on the action you just  
did, or should i set & call a variable instead?

appreciate it,

John.

Make sure to use == and not = though…

thanks, it suddenly struck me that i could this this another way.

you see i’ve got the main layout in…

layouts/application.rhtml

so by putting in a code to pull in a partial i could not specify the  
controller to pull it from and then it would pull that partial from the  
controller / view the actions sitting in then and there.

as long as i have the same named partial in each view, pretty sweet.

however thanks for the params[:action] should work out right, yep got  
the == meaning check if identical.

thanks guys,
