I have AS (as a plugin) working in another app just fine (I dont remember this
issue...) - its also using Rails 2.3.9, on same dev box.
Now trying to add it to a new app and getting this error when running
the webrick, script/server:
/Users/kimptoc/.rvm/gems/ruby-1.8.7-p302/gems/activesupport-2.3.9/lib/
active_support/core_ext/module/aliasing.rb:33:in `alias_method':
undefined method `number_of_pages' for class `Paginator' (NameError)
from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p302/gems/
activesupport-2.3.9/lib/active_support/core_ext/module/aliasing.rb:
33:in `alias_method_chain'
from /Users/kimptoc/Documents/ruby/borisbikestats/vendor/plugins/
active_scaffold/lib/extensions/paginator_extensions.rb:9
I couldn't find any previous references to this error.
Embarassingly I dont know which version of AS I am using successfully... it says 1.2RC1 in the CHANGELOG file, but I seem to remember trying a few of the forks...(is there somewhere I can see which fork is in use...). I have tried using the the 'main' activescaffold in the new project, but it fails as above, but so does using the same plugin that is in the working project :(
Thanks in advance for any pointers as to what I am doing wrong.
Thanks,
Chris
PS Just realised that new Rails was using Rails 3 and old/working one was 2.3.9. It seems you need to use an alternate branch of AS for Rails 3, like this : https://github.com/vhochstein/active_scaffold/wiki
This is just a guess, but built in pagination was removed in Rails 2 as I recall, and you needed to install the classic_pagination plugin to get that functionality back.
I only used ActiveScaffold once, but the error there says paginator_extensions.rb ... it's probably monkey patching the old Rails paginator? Therefore the class exists but the number_of_pages method doesn't.

I'm relatively new to using Ruby on Rails and I've been trying to use ActiveAdmin for my project. However, despite even starting my Rails project from scratch again and trying to update anything related to the problem nothing I've been doing seems to work.
I don't know why, but my project simply refuses to accept stylesheet_pack_tag as a method.
I have been setting up ruby on rails on my mac - I'm learning (I guess we all are) - I run rails and go to the site where the app is and see the following error.
undefined method 'engines' for Rails::Engine::Railties:Class
The app was running fine until I bundle installed the dependant gems (I think I may have updated them).
How do I read this error so I know what actually is wrong.
If I have to define the method, how do I do that - what with and where?
Thanks in advance,
Dan
I've been developing a Rails 4 app on Windows. I recently switched to Ubuntu (13.10) and brought my project over. I'm suddenly encountering a new error.
I have several controllers that use the same authentication logic, so I moved that code to a concern called "Authenticating.rb" and put it in my app/controllers/concerns folder. I then put
include Authenticating
at the beginning of each controller. This worked perfectly under Windows, but in my new Ubuntu version it throws this error:
Routing Error
uninitialized constant UsersController::Authenticating
When I comment out the include line it works just fine. Additionally it works if I explicitly require the concern file (require "#{Rails.root}/app/controllers/concerns/Authenticating.rb"). However I don't want to have to do this for every controller, and I shouldn't have to--Rails is supposed to load this automatically.
Thanks in advance for your help and advice.
EDIT: I should add that on Windows I was using ruby 1.9.3 and on Ubuntu I've moved to 2.0.0. Might this have something to do with it?
rename Authenticating.rb to authenticating.rb
Trying my luck with the vote_fu rails plugin. The functionality looks like exactly what I need for a project of mine, but I have hit a roadblock. I have followed the github readme to the letter, installing it as a plugin.
I have put acts_as_voteable on my "Event" model and acts_as_voter on my User model.
In the console, when I try:
>> event.votes
or
>> user.votes
it successfully returns an empty array.
but when I try to do the following:
user.vote_for(event)
I get
"NoMethodError: undefined method `user_id' for #<Vote:0x7f5ed4355540>"
Any ideas? I'm probably just missing something obvious, but maybe something is missing from the plugin's readme.
Thanks.
[Update]
I created a blank application and the plugin works fine, so I think that this problem might be being caused by the use of the "desert" plugin, as my User class is split over two files. If I find the answer, I'll post it so that in the off chance someone else runs into this it may be some help.
Cheers.
Ok, I haven't found a definitive reason why this problem occurred, but I do have strong suspicions that it is due to the use of the "desert" plugin, as my User class is split over two files (the project is using the CommunityEngine plugin as a base),
Anyhow, I found a work around (something I should have tried before posting here). Instead of installing vote_fu as a plugin, I installed it as a gem. And now vote_fu seems to be humming along nicely.
So let that be a lesson to you all!

I'm spending my first few days with cucumber/selenium trying to figure out whether RBB is the thing I want to use in my latest RoR project.
My setting: Rails 2.3.5, selenium-client 1.2.17, cucumber 0.4.4 etc, quite current in my view.
Following the instructions on https://github.com/cucumber/cucumber/wiki/Setting-up-Selenium I got cucumber/selenium sorts of up and running. Simple step-definitions do work and do produce outpout that makes sense (I dont usually expect more on my first few days with anything :-) ).
My problem: I am trying to access the rails session-hash in my step-definition...and failing miserably. Refering to "session" in any "given"-clause just presents me with "undefined method `session' for nil:NilClass (NoMethodError)"
Is there any secret handshake I am missing in the docs???? Anything that has to be configured my my environment so using the session-hash is possible?
Regards
Michael
This should happen right out of the box. If you add a debugger line right to a step definition you should be able to type "session" and see something like:
{:session_id=>"f978d4220252b7e1ca51fb7319d5a365", "flash"=>{}}
