Hi,I am trying to create a user autentication system. Normally the  
user autentication system works fine but now i want to include the  
login and logout in the header of the application. so that u can login  
and logout in any part of the application

this it the weird part of the problem. let’s say i am in articles/  
search then i login and logout there is no problem. but when i go to  
articles/show i get

which does not make sense cause the logout link is linked to  
the :action :destroy

Next i try logging out in search and logging in inside :show and  
logging out inside :show as well and everything works.

here is the Layout :

\<%= stylesheet\_link\_tag ‘star’ %\>  
\<%= javascript\_include\_tag :defaults, “jquery” %\>

 \<%= render :partial =\> 'login\_panel'%\> 

```
  <%= yield %>

```

Partial view “\_login\_panel.html.erb”:

  \<% if logged\_in? && session[:user\_id]%\>

```
  <%= User.find(session[:user_id]).login %> ,you are logged in! || 

```

 

\<  
%= link\_to\_remote “logout”, :url =\> {:controller =\>  
‘articles’, :action =\> ‘destroy’} %\>

 

```
  <% else %>

```

 

\<% form\_remote\_tag :url =\> {:controller =\> “articles”, :action =\>

after more inspection i have found that it is the link\_to\_remote that  
has lost its :url. it seems to be picking up the url of the action  
page. Does anyone know why?
