Hello all,
I''m learning Ruby on Rails and still kind of new at this.
I have two different layouts (standard page and dialog box) for a view
(show).
How do I set each layout in the controller to show the different layout?
Something like this...
- Controller -
def show
@project = Project.find(params[:id])
if ''view is page''
render :layout => ''page_layout''
else
render :layout => ''dialog''
end
Where would I set the variable? in the show.html.erb?
Thank you for any help.

I would put the content of the page/dialog into a partial. I''m going to assume that your dialog version will be rendered by an AJAX call. In that case I would use respond_to to determine which layout to render: respond_to do |format| format.html # Render page with default layout format.js # Render the dialog version end In case you''re not rendering the "dialog" version with AJAX then you might want to use a custom MIME type to render the alternate layout: respond_to do |format| format.html # Render page with default layout format.dlog # Render the dialog version as HTML using custom format type end> Where would I set the variable? in the show.html.erb?I''m not sure how you will be determining which layout to use, but if you absolutely had to store this in a variable you would need an instance variable on your controller. However, as I mentioned before moving the decision into the request seems like the better approach. -- Posted via http://www.ruby-forum.com/.

Does the user do something to indicate which view he wants or is it something else? Is it possibly that you want a different view when just displaying the data from when the user is entering the data in the first place (or editting it)? Colin
I apologize to all for being unclear. It''s just the newbie coming out.
Let''s try again.
I have a ''projects'' layout within the
''Views'' folder, with a heading,
nav bar, and content area.
When you select "show" on the index.html.erb of the
''projects'' View
folder, the project information displays in the content area. I wish to
not change this.
Within another template, I have a link that produces a dialog box
(Prototype Window) that displays the project information. When the
dialog box appears, the project information displays as the first
layout, with header, nav bar and content area.
I created a layout for displaying just the content area and set it in
the controller.
- controller -
def show
@project = Project.find(params[:id])
render :layout => ''dialog''
end
When I go back to the original index.html.erb and click on the
''show''
link, my ''header/nav bar/content area layout disappears. All that
displays is the project information without any styling.
I hope this clears up things.

When you say you have a link that produces a dialog box is that a javascript box called up without going back to the server or what?> > I created a layout for displaying just the content area and set it in > the controller.Is this the projects controller or another one?

All that > displays is the project information without any styling.It appears that you are saying that clicking on the same link (which presumably is just a get on the controller, nothing fancy, shows a different result in the browser? Odd to say the least. You have not shown us the code for projects_controller#show. Is there some logic in there that could make it do something different the second time? Have a look at the generated html (View, Page source or similar in browser) and see what the difference is. Have a look in development.log and see what is different there. That may give you a clue.> > I hope this clears up things.Not entirely. :) Colin> > JohnM > > > Colin Law wrote: >> 2009/10/14 John Mcleod <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org>: >>> >>> Hello all, >>> I''m learning Ruby on Rails and still kind of new at this. >>> >>> I have two different layouts (standard page and dialog box) for a view >>> (show). >> >> It is inadvisable to use the word layout here as that word has a >> particular meaning in Rails.
