I have a problem as per another open question I have here which I just need a quick fix for in the meantime so I can get onto the next bit of the project, and I'll move back to fix this properly later.
I want to know, is there a way in rails to 'cancel' a redirect_to action if it was called earlier in a controller method? I don't want to do redirect_to :nothing, I just want to make it as if redirect_to wasn't called.

Does anybody know how to upload a document to later show in a Rails application (as text)? Is Paperclip the right gem to do this? If it is how? (I have uploaded images before with Paperclip).
I like Paperclip. It seems well documented, and has worked well for everything I have needed. (I don't personally know any of them, but the clever folks at Thoughbot have created some pretty useful stuff, for which I feel indebted to them).
Obviously, you need to add Paperclip to your Gemfile, and (if you are using bundler) do your bundle install
Add to your model
has_attached_file :aFile
Add to you controller something to catch whatever you name it in your view (probably in your create and update methods)
#profile.aFile = params[:profile][:aFile]
Probably should check for its existence, if it is a required param
if params[:profile][:aFile].blank?
redirect_to #profile
else
render :action => 'do_something_interesting_with_file'
end
And that's about it. Don't forget your config entries. For example, if you are using some kind of post-processing on the file
Paperclip.options[:command_path] = "/opt/local/bin/"
I found this to be extraordinarily helpful

I'm finding it difficult to understand how ActiveAdmin(http://activeadmin.info/) works with existing controllers
I have the following controllers
app/controllers/projects_controller.rb
and I was successfully able to implement ActiveAdmin UI over my views in the above controller. But my question is I have added the following before_filter in my controller
class StaticContentsController < ApplicationController
before_filter :list_content_types
def index
#static_contents = StaticContent.all
end
end
But this filter seems to be not executing, in fact I changed the code inside the index method to
#static_contents = abc StaticContent.all
As it should give and error because of 'abc' section, but surprisingly my app works with out an error. My guess is 'ActiveAdmin' reads controllers my its own, not the existing ones
this is my index action path
http://localhost:3000/admin/static_contents
and this is in development mode
Can someone help me on understanding how controllers works with ActiveAdmin or am I missing something here
Following are my configs
rails (3.0.0)
ruby 1.8.7
activeadmin (0.3.2)
thanks in advance

Activeadmin controllers are not the same as your app's controllers, they are separate. The reason your code is not causing an exception from the activeadmin interface is because that code is never hit. The activeadmin controller documentation specifies how to modify the default activeadmin actions.
I found a tutorial here https://github.com/plataformatec/devise/wiki/How-To:-Migrate-from-restful_authentication-to-Devise-, however it seems like it is missing pieces of what to do, for example the restful_authentication plugin is still there...how do I remove it? Then how does Devise know what to get for my App...I've tried it but it just keeps breaking my App.
Erase everything in the user.rb controller (or your controller)
Make Sure all of Restful_Authenication is gone (there is quite a bit of includes that may be presnet)
Make sure devise_for :users is present in the routes.rb file
Look for method errors and replace them back in the User.rb controller.
Think that fixed it.
I've got Devise working on my Ruby on Rails application but viewing the user requires authentication and I don't want that. I've tried setting authenticate_user like so:
class UsersController < ApplicationController
before_filter :authenticate_user!, :except => [:show, :index]
..
end
But it still redirects to the sign_in page. Can anyone point me in the right direction?
Cheers,

PS: Please excuse my n00b-ness
Doh!
I was getting confused and had the wrong path. I been scratching my head for ages on that.
I fixed it...
I always use to copy controller files from devise gem folder to my applications controller folder
The devise controller files can be found here /usr/lib/ruby/gems/1.8/gems/devise-1.1.2/app/controllers/ (may be at different location in your case)
Copy devise folder in there and paste it to app/controllers/ and then customize registrations_controller as per your need
But I believe there must be some good solution on this. By the time you can use this.. :)
It gives me the creeps,i'm done, i need some help here, i reverted multiple times back but i can't find the error.
Simple controller (customers),a simple form for adding a customer via :remote => true and the controller does respond_to do |format| { format.js } . Works fine, renders my create.js.rjs template.
I work for a few hours without making any javascript changes or changes to my controllers or authorization etc.. and when i try it again it's not working anymore.
What i mean with not working: Controller gets called, record saved, all partials rendered. But no javascript evaluated, not even a simple alert(1) at the beginning of the file.
I tried with different prototype.js versions and different rails.js versions, but nothing helped. I hope someone has a clue about this or already experienced this.
It's not that i don't want to post code. But it won't help. Its basic code that works and, after some changes where i don't know what i really changed (some locales here, some css there, html templates from a completely different controller a bit..)..
Currently developing with: ruby 1.9.2, rails 3.0.3, prototype 1.7 RC3, rails.js from github.
SOLVED
How stupid, I missed the part where the template naming changed. My application templace was named "application.rhtml". It worked until now. As it stopped to work, I changed it to "application.html.erb" and now it's working.
