Rails - May 2006 - Action Variables Not Available In The View For A Specific Action

I am setting an action variable in my PagesController such as:

def manage
  render(:layout => "admin")
  @strOut = "STRING Variable Set From The MANAGE Action!"
end

And in the /views/pages/manage.rhtml view, I don?t have access to that
@strOut variable by trying to call it as: <%= @strOut %>

However, I am setting the same variable in another action in the controller
such as:

def view
  @strOut = "STRING Variable Set From The EDIT Action!"      
end

... and I have full access to it in /views/pages/view.rhtml

The only difference in the actions being this:
render(:layout => "admin") ...in the manage action.

So, I want the manage action to use /views/layouts/admin.rhtml, and the edit
action to use /views/layouts/pages.rhtml.

I''m not sure if the layouts have anything to do with it but I really
don''t
know why that variable cannot be called from the view.

It''s an order thing.

render  :layout => ''admin'' actually copies the instance
variables from
the controller for use in the template.  It''s actually a bit more 
complicated than that but that''s the just.  In otherwards, at the time 
the instance variables are copied to the template, your instance 
variable @strOut does not exist and is not copied.  Just code your 
method like:

def manage
   @strOut = "BLAH"
   render :action => ''admin''
end

and all should be good.

Excellent, re-ordering them worked. Thanks very much.

You set the variable after the view was rendered. Swap those two lines.
