Some more checking shows it broke with rails r8669 with the introduction of
TemplateFinder #10800. 

http://dev.rubyonrails.org/changeset/8669

I got this too...

I have this problem too... Don't know how to fix it..

Just a note for others who may encounter this: you can freeze to Rails 2.0.2 (or I
would assume r8668) to continue working with edge/trunk ActiveScaffold until this
issue is resolved.

I really needed the newest features from edge rails so I did my best to patch
active_scaffold to work properly. The patch I'm attaching is from a piston managed
version of active_scaffold, and piston just relies on unix diff, so the patch is
probably not directly appliable to the active_scaffold codebase. In the diff, the
versions of files with .tmp in their path are from the active_scaffold trunk, -r727. 

In addition to the patched code, I also needed to call the
ActionController::Base.prepend_view_path method in all of my active_scaffold
controllers, as well as append the path to active_scaffold default/views in the
active_scaffold config block. So, in my A_S controller I have a class level method
call like so:
 
prepend_view_path("#{RAILS_ROOT}/vendor/plugins/active_scaffold/frontends/default/views/")

As well as a cfg block call:  
cfg.template_search_path << "vendor/plugins/active_scaffold/frontends/default/views/"


My changes are very brute-force and fragile, but I was hoping it may provide a useful
stepping stone to a more robust fix for this issue. 

One last thing, for others looking into this issue the problem came about via this
ticket:
http://dev.rubyonrails.org/ticket/10800
and this changeset:
http://dev.rubyonrails.org/changeset/8683

This problem also occurs with tags/active_scaffold

This is no longer only an edge rails problem. The current gem version of rails is
2.0.2.9216 and also exhibits this problem. Therefore I would suggest increasing the
priority of this issue. Thanks, Frank.

Ace,

I tried manually applying your patch and now AS complains about missing views that
don't exist.  Any suggestions?

Erik,

Please check out this thread for more up to date information on working with edge rails:
http://groups.google.com/group/activescaffold/browse_thread/thread/567770b55aba525c/767dd38f61fb5744?lnk=gst&q=acechase#767dd38f61fb5744

With the code from this issue (#515), plus the code in the above forum thread, I've
got ActiveScaffold working under Rails 2.1RC1. 

I haven't heard a word from the AS maintainers on what their plans are WRT to
updating the code to work with the new rails. If I thought they were ready to take on
the upgrade I'd be happy to consolidate what I've got working into a single coherent
post. Unfortunately, I haven't heard word one from the maintainers on this issue.
anyone out there know otherwise?

-acechase

Just an FYI for everyone. The patched version of AS blows up if the AS_acts_as_list plugin is installed.

this is definitely still a problem with AS+Edge

look, folks, I don't think another '+1' is going to help. 

This is a known bug and apparently the AS committers don't have time to deal with it.
If you really want to help out, rather than giving yet another +1, make some noise
about this issue. blog about it. get in contact with the AS project leaders and bitch
to them about it. hell, submit a fix if you've got the time.

This is not rails core, I don't think anyone really cares how many +1's are on a
ticket. If you want to talk about architecture changes, or issues you're hitting with
the existing patches, that's great. but all the +1's are just worthless noise.

sorry for being mr. poopy pants.
-ac

It's okey acechase, I agree.  If you only want to say "+1", please just STAR the
issue.  All of us who has stared this issue to show our interest in getting it fixed
are getting emails every time you "+1" this.  Unless you have something to actually
contribute to the issue, please just star it!

FYI, there is a GIT branch for rails 2.1, they are dealing with it.  Help them out by pulling the branch and testing 
out their patches!  Submit new bug reports if there are any!

http://github.com/activescaffold/active_scaffold/commits/rails-2.1

cool. thanks for the followup, very useful! :D

an additional FYI: Jose Fernandez has created his own AS branch where he has applied
the patches discussed in this ticket as well as a couple other patches to get the
code working with Rails 2.1.
http://github.com/jfernandez/activescaffold/tree/master

Maybe it's better for everyone to consolidate their testing efforts on the official
AS rails-2.1 branch, but I figured folks might be interested in this jfernandez
branch in case they need it immediately. Just keep in mind that the jfernandez branch
is a patch, not a complete fix (a full fix will require some architecture changes, I
think). So if you're looking to help move AS forward with rails 2.1 then it's
probably best to try and stick with the rails-2.1 branch.

You know what drives me nuts?

I see http://github.com/activescaffold/active_scaffold/commits/rails-2.1

But how the heck do you clone it?

git clone git://github.com/activescaffold/active_scaffold/commits/rails-2.1
git clone git://github.com/activescaffold/active_scaffold/rails-2.1
git clone git://github.com/activescaffold/rails-2.1

all fail

git clone git://github.com/activescaffold/active_scaffold
cd active_scaffold
git branch -r (just lists the branches)
git checkout origin/rails-2.1

http://www.sourcemage.org/Git_Guide

thank you!!!  not exactly intuitive..

btw after switching to this I get (same as
http://groups.google.com/group/activescaffold/msg/58b8d097915c9c13 I think)

 NoMethodError in ThingsController#index

You have a nil object when you didn't expect it!

Maybe give jfernandez's branch a try: http://github.com/jfernandez/activescaffold/tree/master

Is this going to get fixed?

For what it's worth origin/rails-2.1 as specified in
http://code.google.com/p/activescaffold/issues/detail?id=515#c26 is working for me
against rails edge.

Tried both jfernandez's branch and origin/rails-2.1 branch on Rails 2.1.0 installed from 
gem. 

Same error as andrewroth is having.

Update: jfernandez's branch IS working. The trouble was with generated with scaffold rake 
task methods in controllers. After leaving only one line in controllers (like 
"active_scaffold :user") it works.

Success reported using origin/rails-2.1 with rails release 2.1. Don't understand
quite why this isn't merged to live yet...

I have a strange problem. I've some controllers with active_scaffold which run well
and some others with this problem :  

NameError in Admin/videoController#index

uninitialized constant Admin::VideoController

So I don't understand what's appens. I've tried to install jfernandez's branch but
I'm not sure how doing this well. 

For the moment, I installed with git : git clone
git://github.com/activescaffold/active_scaffold.git vendor/plugins/active_scaffold &&
rm -rf vendor/plugins/active_scaffold/.git

and I installed jfernandez's branch with the tar on the website. I placed all the
content into vendor/plugins/activescaffold/

Thx for help

really nobody's help

git clone git://github.com/activescaffold/active_scaffold
git checkout origin/edge

..appears to work fine with rails 2.1 at least during my short test.

Excuse but I solved this problem with another fork of AS.
Today I use this branche (edge)

But I have another trouble. I have two tables videos and osversions
I have a HABTM association between them.

osversions_videos :id => false

If I go on the video interface, in the fields osversions, I have the names of the
osversions attached to this video. But if I click on them, I have this error : 

 ActiveRecord::StatementInvalid in Admin/osversionController#table

Mysql::Error: Unknown column 'osversions_videos.video_id' in 'where clause': SELECT
DISTINCT `osversions`.id FROM `osversions`     WHERE (osversions_videos.video_id =
'808')  ORDER BY osversions.`version` ASC LIMIT 0, 40

But I can create or update videos and the modifications appear on the video interface

I tried to replace my HABTM association with a has_many :through association, this
solved the problem but I can't edit osversions of a video or create another video.

So what can I do to solve this.

Thanks for reply 

+1 please fix this issue.

Been using it with 2.1 and master from github for several months now.

Sure would be nice to have the main AS installation pages say that git is the
recommended method, *not* the svn repository.  Save us all a lot of trouble as it is
the source of the problem.

http://activescaffold.com/tutorials/getting-started

hopefully this info will be stale *very* quickly.

Today I was forced to upgrade a site from Rails 2.0.2 to Rails 2.2.2, because Dreamhost upgraded to Rails 2.2.2 and they DELETED the Rails 2.0.2 gems.  I woke up to a dead 
site and I have no choice other than upgrading.

I ran into this exact same "find_full_template_path" problem with Active Scaffold, so I tried to upgrade Active Scaffold.  Unfortunately the current version of Active Scaffold from 
github has the exact same error with Rails 2.2.2.

Here's my Active Scaffold upgrade:

This puts me in an awful situation.  I'm going to attempt to freeze 2.0.2 gems into my project to avoid the issue until Active Scaffold is truly compatible with Rails 2.2.2.

This issue is closed. If you're having issues with edge (eg 2.3) rails and as master
branch then please open a new ticket.

Hi all
I new to the forum and I'm having a similar problem starting Mogrel with the master
AS.  I see this issue is closed but I don't see another defect opened to resolve the
issue.  Can anyone point me to the new defect?  If not, I'll open one with the stack
I'm getting on start.
thanks

Please open a new issue with your stack traces from mongrel.log and your
RAILS_ENV.log if one exists.

I had the same issue. What I realised is that git is not installing the proper
version. I downloaded it and copied it to the vendor/plugin directory and worked. 

I have rails 2.2.2
