Partials don't use the layout by default. It seems strange that you'd want to render a partial from your index action... I'm guessing that's not ultimately what you want to do.

Hi Jeremy
Thanks for your explanation. Yes you are right I am not rendering partial from my action.
But is it wrong to do so? because in other many application code I seen the same thing.
Thanks

If you see partials being rendered directly in controller actions in other code, well, that other code is bad as well.
You really generally only render partials from view files, not directly from controller action methods.
In below code snippet.
- I need to compulsory pass an layout option to render partial line. As you can see I am all ready setting the layout in set_layout method.
- If I remove the (:layout=> :set_layout) from render line then it doesn't render the proper layout.
If anyone explain me why it's happening like that or am I doing something wrong?
Thanks
DG
