Ok, so I know this is a totally obvious question, but it''s dumbfounding
me
right now. I''ve got Ruby on Rails going and I know this has worked
before...
I have a html fragment that does:
---
<%= link_to_remote (h(''<Description>''),
:id => ''1'',
:update => ''todo_display'',
:url => { :action => :render_todo_display }) %>
---
This is the code in the same controller:
---
def render_todo_display
render(:layout => false)
@par = @params["id"]
end
---
and this is the .rhtml file:
---
just somethign</br>
<%= @par %>
just somethign else</br>
---
But when I click on the link in the html fragment, the correct section gets
updated with just this:
---
just somethign
just somethign else
---
I''ve tried:
@par = params[:id]
that didn''t work. I know this is totally easy, but what the heck is
wrong?
