I am trying to upgrade my app to mongoid version 3. In my dragonfly initializer I used to have this:
app.configure_with(:imagemagick)
app.configure_with(:rails) do |c|
c.datastore = Dragonfly::DataStorage::MongoDataStore.new :db => Mongoid.database
end
Mongoid.database no longer exists. What is the best way to configure the connection for dragonfly now?
I use Mongoid.load!("config/mongoid.yml", :development) instead of Mongoid.database. And it's works for me.

background
I am trying to migrate an old Rails 2 (Ruby 1.8.7) app to Rails 3.0.9 (Ruby 1.9.3) — yes it's a stepping stone to get it to Rails 4 and Ruby 2.2 — and I've hit the following problem.
The original app makes extensive use of an old Active Form gem which we've hacked slightly to support Ruby 1.9.
It mostly works, but there appears to be some issue with how it interacts with the ActionView::Helpers::AssetTagHelper that's part of ActionPack 3.0.9.
In my specific case I have an ActiveForm::DateCalendarSection (built dynamically) which subclasses ActiveForm::Element::Section, which, according to self.class.ancestors, is a subclass of ActionView::Helpers::AssetTagHelper. Looking at the ActiveForm source however there is no mention of AssetTagHelper or asset_tag_helper so how they are actually connected remains a mystery to me.
Problem
Calls to the method image_path result in an error
undefined local variable or method 'config'
The call to image_path is simply a wrapper around a call to compute_public_path in ActionView::Helpers::AssetTagHelper
# File actionpack/lib/action_view/helpers/asset_tag_helper.rb, line 741
def compute_public_path(source, dir, ext = nil, include_host = true)
return source if is_uri?(source)
source += ".#{ext}" if rewrite_extension?(source, dir, ext)
source = "/#{dir}/#{source}" unless source[0] == //
source = rewrite_asset_path(source, config.asset_path)
has_request = controller.respond_to?(:request)
if has_request && include_host && source !~ %{^#{controller.config.relative_url_root}/}
source = "#{controller.config.relative_url_root}#{source}"
end
source = rewrite_host_and_protocol(source, has_request) if include_host
source
end
Diving into that with binding.pry it's evident that config is indeed not defined. Likewise controller is also not defined.
Question
What would have changed between Rails 2 and Rails 3, such that methods from ActionView::Helpers::AssetTagHelper can no longer access Rails' config or the current controller?
It could be you don't have enough of the Rails support loaded. Maybe pull in everything inside your gem with
require "active_support/all"
Alternatively, have a look at how modern Rails hooks things up via a proxy to the config:

I am following the documentation (http://amazon.rubyforge.org/) to try to begin working on S3 into my application (for serving files to the end user) but I keep running into errors.
Here is my Model:
class File < AWS::S3::S3Object
set_current_bucket_to 'test-bucket'
end
This is what I am trying via the Rails Console:
File.find 'test.pdf'
But I keep getting this error:
undefined method `find' for File:Class
Not sure what I am doing wrong here... anyone else run into this issue?
File is not a very good name for your model as it gets overwrited by Ruby's standart class File (docs). Just choose another name and everything will just work!
So I'm using Spree as my shopping cart in Ruby on Rails. Spree is version 1-1-stable, and Ruby is v1.9.3, and Ruby on Rails is v3.2.3.
I have a remote host that has images that I want to download for my Spree cart. This is the code I'm using to pull it. Some of it may not make sense, because I'm trying to do whatever I can to get this to work so it could use a little cleaning.
# Add image to the product
vendor_id = plink_and_pull(item, "VendorID")
image_name = plink_and_pull(item, "ImageName")
# TODO: add if image exists to this unless
unless image_name.nil? || vendor_id.nil? || plink_and_pull(item, "ImageFound").to_i == 0 || File.exists?("/public/prod_images/#{vendor_id}/#{image_name.gsub(' ', '%20')}")
unless Dir.exists? "/public/prod_images/#{vendor_id}"
Dir.mkdir("/public/prod_images/#{vendor_id}", 777)
end
file = File.new("public/prod_images/#{vendor_id}/#{image_name.gsub(' ', '%20')}", 'w+')
file.binmode
open(URI.parse("http://login.xolights.com/vendors/#{vendor_id}/large/#{image_name.gsub(' ', '%20')}")) do |data|
file.write data.read
end
img = Spree::Image.create({:attachment => "public/prod_images/#{vendor_id}/#{image_name}",
:viewable => product}, :without_protection => true)
end
But the error I get says "No such file or directory - /public/prod_images/29" and it references the "Dir.mkdir" line up there. However, I manually created this directory to try to get it to work. In my exception rescue I have the working directory printed out, which is the base directory of my app on my machine. (I am running this on localhost atm.)
I am thinking that maybe I need to do something in my routes.rb file? But I am such a novice at Ruby on Rails routes that I'm not sure where to start... or even if that's the problem here.
I am not that familiar with RubyMine. But rest assured that it's not about routes. It's not Rails-specific. It's Ruby (and OS)-specific because Dir.mkdir is part of standard Ruby library. Just remove the leading / from the path and see whether it works. (So, the actual path will be {your Rails app's root directory}/public/prod_images
I have an application (rails 3.2) with haml (3.1.4) emails. In the email template I wanted to use link_to, but apparently none of those 4 is working in production:
#{link_to(my_models_url)}
= link_to(my_models_url)
/ #url set to my_models_url
#{link_to(#url)}
= link_to(#url)
On development mode everything works fine, but in production, I keep getting the following error:
No route matches {}
actionpack (3.2.0) lib/action_dispatch/routing/route_set.rb:503:in `raise_routing_error'
It works when I use helper methods before:
/ #my_link set to link_to(my_models_url)
#{#my_link}
= #my_link
But this is not convenient, if there are more links in the email and in general I don't see why any of the first 4 options should not be ok. I have no idea where is this problem comming from. I would appreciate any help on this...
SOLUTION:
Thanks to iWasRobbed I found where my problems were:
all {resource}_path and {resource}_url have to be set in mailers as #variables, they are not available in mailer views
apparently link_to() method in mailer is not the same as in rails views... it always needs 2 arguments, so instead of link_to(#link) available in views, one needs to do link_to(#link,#link). Pffff...
You need to declare the URL within the mailer.rb file. This isn't a HAML issue so much as it's just the way ActionMailer was designed.
def some_mailer_here
#url = my_models_url
end
Then in your mailer view you can do:
= link_to("My models URL", #url)

I'm struggling to get my app to display a timeline of feeds from my app. So far I've used the oauth-plugin, oauth and twitter gems (for rails3) to get it authorised. This has worked just fine.
Now I'm struggling when I try and connect.
I end up with an error:
uninitialized constant Twitter::OAuth
Have checked I don't have another action calling twitter (as in another post here). But so far, no luck.
Hope someone can help!
Edit -
I forgot to mention I'm using Devise to authenticate my users. Have tried inserting:
require 'twitter'
But still no success..
-- EDIT TWO --
Found a solution on the twitter gem git site about depreciating this in version 1.0.
I've now replaced the code in my twitter_token.rb file with:
def client
unless #client
#twitter_oauth=Twitter::Client.new(:TwitterToken.consumer.key,:TwitterToken.consumer.secret)
#twitter_oauth.authorize_from_access(token,secret)
#client=Twitter::Base.new(#twitter_oauth)
end
Which gets rid of that error but now leads to another :(
undefined method `consumer' for :TwitterToken:Symbol
I have also tried this:
def client
unless #client
#twitter_oauth=Twitter::Client.new(:oauth_token =>'TwitterToken.consumer.key', :oauth_token_secret=>'TwitterToken.consumer.secret')
#twitter_oauth.authorize_from_access token,secret
#client=Twitter::Base.new(#twitter_oauth)
end
Which gives the following error:
undefined method `authorize_from_access' for #<Twitter::Client:0x00000102da1530>
Any ideas? I'm going insane!
I'm going to answer my own question here - if it helps one person, it's worth it considering I lost three days to it.
Using the latest twitter gem, devise and oauth-plugin. I was seeing a lot of errors. The latest twitter_token controller on the oauth-plugin site does not work, even though it's been updated for a recent twitter gem..
In the end, I deleted my entire twitter_token.rb file and started again:
require 'twitter'
class TwitterToken < ConsumerToken
TWITTER_SETTINGS={:site=>"http://api.twitter.com", :request_endpoint => 'http://api.twitter.com',}
def self.consumer
#consumer||=OAuth::Consumer.new credentials[:key],credentials[:secret],TWITTER_SETTINGS
end
def client
Twitter.configure do |config|
config.consumer_key = TwitterToken.consumer.key
config.consumer_secret = TwitterToken.consumer.secret
config.oauth_token = token
config.oauth_token_secret = secret
end
#client ||= Twitter::Client.new
end
end
You can then update twitter using something like this:
<%= current_user.twitter_token.client.update("At last it's working!") %>
Also, make sure you're using the rails3 branch of the oauth-plugin..
