problem getting rails1 app running under rails2

I'm sure others have already solved this problem - porting an existing rails1 app to rails2.

A sketch of the problem - I'll be happy to furnish as much detail as may be needed - I'm hoping this is/was a standard problem.

I've just upgraded to current rails gem (2.1.2) from 1.2.5 and can't get my app going. It appears that my standard.rhtml (renamed to standard.html.erb - along with other *.rhtml) is not being rendered - there's no mention of it (in the window in which script/server is running) when I open the app in the browser - the view is rendered, but without the appropriate css. standard.rhtml created the navigation panes used in all views. I'm using FF3 and ubuntu hardy - shouldn't be relevant since rails1 app was running OK in this environment.

Could someone please point to where I need to look. Any and all help appreciated

This message used to appear in the script/server output, when the app started,

   "Rendering within layouts/standard"

that's the standard.rhtml (in layouts) that was referring to

Hi, I haven't had this particular problem with converting an app, but I have found a way to convert that seems very painless and quick for me. Worked well twice now.

I just create a new rails 2.x app, and then copy the appropriate stuff over from the old app (like all of the stuff in apps folder, and plugins, etc.)

I have NOT found it necessary to rename the endings of the view files. 2.x is backwards compatible with the "old" .rhtml ending.

Just the other day I got a medium sized project converted and working in just a few hours, including setting it all up on a new server box.

Copying stuff into a new rails project seems a lot easier than doctoring up an old project to make it 2.x compatible.

OK, I think I see the problem, but not the solution.

My ApplicationController contains the line "layout 'standard'"

Is this command is no longer valid? It seems that it's not doing what it used to.

Here's the class:

$ cat application.rb # Filters added to this controller apply to all controllers in the application. # Likewise, all the methods added will be available for all controllers.

class ApplicationController < ActionController::Base   layout 'standard'

  # Pick a unique cookie name to distinguish our session data from others'   session :session_key => '_dancedb_session_id' end

OK, yet again - putting "layout 'standard'" in EACH of my controllers works! Having "layout 'standard'" in ApplicationController but not in individual controllers does not work.

So, it seems that the individual controllers are not inheriting from ApplicationController as I thought they should (and used to do).

Is it possible that I have configured (or failed to configure) something to make this happen?

I'm happy that the app works again, but am confused about what changed.
