Error trying to connect to panda - ruby-on-rails-3

I am following panda guide to integrate a rails app to panda for embedding a video in my app.
I have setup the panda.yml as follows:
development:
access_key: 805264cac2c2cbf61e69
secret_key: 133aa3bbf1d8cdf56f13
cloud_id: cloudbear
My panda.rb initializer file has the following (I do not want to host this app in heroku):
Panda.configure((ENV['PANDASTREAM_URL'] ||
YAML::load_file(File.join(File.dirname(__FILE__),"..",
"panda.yml"))[Rails.env]))
My gemfile:
gem 'panda', '~> 1.5.0'
When I try to fire up the rails console I get:
/home/vasu/.rvm/gems/ruby-1.8.7-p371/gems/panda-1.5.0/lib/panda/panda.rb:12:in
`configure': missing auth params or block (ArgumentError)
A look at the configure method inside the panda module shows that it expects either auth_params or block.
What do I seem to be missing in my configuration?

When i put in the cloud id (instead of its name as I had done above), I am able to fire up the rails console and connect to panda. cheers!

How to set sinatra-authentication to use erb instead of haml?

I'm trying to set up the sinatra-authentication gem in a simple sinatra app, and running into an issue where sinatra can't find the correct views. I understand that sinatra-authentication uses haml by default, but I'm using erb in this app.
This in mind, I found in the sinatra-authenticaiton docs that there is a setting which allows you to change the template engine, by adding the following to your app file:
configure do
set :template_engine, :erb # for example
end
I've added this to my app.rb file, and sinatra is still looking for the signup.haml when I try to hit the /signup route in my app.
A couple of notes:
I've included the gem in my Gemfile, and successfuly run a bundle install on my app.
source 'https://rubygems.org'
gem 'sinatra'
gem 'data_mapper'
gem 'pg'
gem 'dm-postgres-adapter'
gem 'sinatra-authentication'
I saw something in the documentation that suggested that I may need to specify the location of my view files, so I added the following to my configuration block.
set :sinatra_authentication_view_path, Pathname(__FILE__).dirname.expand_path + "views/"
**I think I've required the gem accurately in my app file by adding
require "sinatra-authentication"
use Rack::Session::Cookie, :secret => 'mys3cr3tk3y'
This gist is a current representation of my app.rb file in the root of my sinatra app. https://gist.github.com/rriggin/5378641#file-gistfile1-txt
Here is a screenshot of the error sinatra throws: http://cl.ly/image/0y041t0K3u3O
When I run the app locally, a 'dm-users' table is created in my local db as expected.
Is there another configuration setting that I'm missing in order to get sinatra-authentication to properly look for the erb templates rather than haml files. Any help would be greatly appreciated.
Thanks
The specs don't test that the template_engine setting works, and looking at the way the setting is called, I believe it's not correct, i.e.
send settings.template_engine, get_view_as_string("index.#{settings.template_engine}"), :layout => use_layout?
might better work as:
send app.settings.template_engine, get_view_as_string("index.#{app.settings.template_engine}"), :layout => use_layout?
that's what I reckon. If you fork the project, change the line and add it to your Gemfile and it works then consider writing a quick spec for it and you'll have improved the mainline of that project as well as fixed your problem.

Rails with Jader gets 'failed to require "fs"' error

I am trying to use client side Jade templates that are precompiled by Ruby on Rails and available through JST.
I added the jader gem
gem "jader", "~> 0.0.8"
In configuration/initializers I created an initializer called jader.rb that contains:
Jader.configure do |config|
config.views_path = Rails.root.join('app','assets','javascripts','views')
config.mixins_path = Rails.root.join('app','assets','javascripts','mixins')
end
In app/assets/javascripts/views I added an index.js.jst.jade file
Hello World!
Lastly in my javascript file I have:
$('#app-content').append(JST["views/index"]());
When I run Rails and browse to the page triggering the code I am getting the following error:
failed to require "fs"
(in /my-project/app/assets/javascripts/views/index.js.jst.jade)
I understand that the problem is that jade is a node.js project and the require function is having a problem. How do I fix the require error?
If you are looking at using Jade templates only on the client side (with Rails asset pipeline), I recommend https://github.com/inossidabile/jade
It's likely there is an error in your index.jade template.
From the jade rails-fix pull request here, ExecJS used by rails does not support require("fs") and will throw 'failed to require "fs" even if it's a template error. Hopefully this should point you in the right direction.
To debug, you can replace the content of index.jade template with with a 1-liner jade placeholder to see if it renders well. Alternatively, try it out rendering the index.jade template with a nodejs server if possible to be sure the template renders without any whinning.

Gem with models

I created a Gem with models (actually, extracted it from the main project) to share amongst the projects we have in our platform.
We have dozens of models, so instead of requiring them one by one, I wrote the following code:
Gem.find_files("my_gem/models/*.rb").each { |path| require path }
I access one of the projects that has my_gem in the gem file and running rails c I get the following output:
/Users/myuser/.rvm/gems/ruby-1.9.3-p194/gems/activerecord-3.2.8/lib/active_record/dynamic_matchers.rb:50:in `method_missing': undefined method `has_attached_file' for #<Class:0x007fad4b93ccb8> (NoMethodError)
One of my models is using the gem paperclip, what is weird is:
If I remove the line declared above to load all the models
automatically, rails c runs fine
If I try to include onlye the model that uses paperclip require
"my_gem/models/paperclip_model" I receive the same error
So then I change my gem to not load any model, and when I try to reference any model from rails console, it says the class is not loaded, but then I run Gem.find_files("my_gem/models/*.rb").each { |path| require path } or require "my_gem/models/paperclip_model" 'they work perfectly and I am able to work with the model.
Has any of you seen the same issue?
Seems that changing require for autoload solved the problem
I changed Gem.find_files("my_gem/models/*.rb").each { |path| require path }
for
Gem.find_files("my_gem/models/*.rb").each do |f|
filename = File.basename(f, '.*')
class_name_symbol = filename.classify.to_sym
autoload class_name_symbol, "my_gem/models/#{filename}"
end
and now it is working.
It sounds like one of the models in your gem depends on Paperclip, but you don't explicitly set it as a dependency. So what's happening is that if your models get loaded before paperclip gets loaded, you'll see the UndefinedMethod error for has_attached_file.
If you use your models in a Rails application which has paperclip as a dependency, and you load those models after the console (or server) has spun up, Paperclip will be present, so you won't see this error.
The solution is to explicitly add paperclip as a dependency in your gemspec, something like:
s.add_dependency('paperclip')
Assuming that this gem will always be used in the context of a Rails application, this should work. If not, you might also need to add the following line to the top of your models that use paperclip:
require "paperclip"

ruby rest_client exception

I try to use gem rest client to access some simple REST service, I have installed the rest-client following these instructions, but when try to use the library, I get the following error no such file to load -- rest_client.
It seems that the library is not recognized.
Did anyone have similar problems with this library?
Make sure you add it to your Gemfile, bundle install, restart server, and if required, require 'rest_client' or whatever the file name is.

How to access Rails 3 engine models in rails console

In the mail app's rails console (irb), how to access engine's models.
update: Say "team" is my main app and "team_page" is the engine. "team_page" is required in main app in the gemfile through 'gem => "team_page", :path => "local/path/to/team_page"'.
when I go to team's rails console, I couldn't access team_page's models.
First you must know the module's name. To help with that, you can run a
bundle show team_page
to find its directory and explore over there (probably under lib/team_page.rb) until
you see the following definition:
module TeamPage
# ...
end
Let's say that the module is called TeamPage. Then just prepend double colon to its name like this:
::TeamPage::SomeModel.some_method
