Cancan permission - ruby-on-rails

I have a rails app that is is using cancan permission and i am trying to block others users from editing another user's dashboard. This has worked for other models but not this one.
profile.rb
belongs_to :dashboard
Dashboard.rb
has_many :profiles
Dashboard_controller
before_filter :authenticate_user!
load_and_authorize_resource :through => :current_profile
Ability.rb
can :manage, Dashboard, :profile => { :user_id => user.id }
When I go to view my dashboard rails gives me the error
undefined method `dashboards'
Any ideas how I can overcome this error?

When you use load_authorize_resource Cancan assumes a plural resource (ie that a profile has many dashboards). According to the docs adding :singleton => true turns this off

BSON::InvalidObjectId illegal ObjectId format Rails 3.1.1

I'm getting the following error when trying to use the delete method in a Ruby on Rails application.
BSON::InvalidObjectId in ServicesController#destroy
I'm using Rails 3.1.1 and MongoDB v2.4.15
Below is the Delete link in question.
%li= link_to 'Delete', #service, :method => :delete, :confirm => "Are you sure you want to delete this service?"
Here is the log error:

When deleting items in other collections it works fine. I'm able to use the "services" edit link without errors. Below is the working Delete link and logs for deleting an attorney.

Anyone have any ideas? Any help would be greatly appreciated.
I found that the issue is in my services_controller
There was a line before_filter :load_service_by_slug, :only => [:edit, :update, :move_up, :move_down]
I had to add :destroy to that line.

Logging which template is being loaded in rails

Lets say I haven't defined any method for a particular action in the rails Controller (like for /users there is no method, and it will directly load up the template). Is there a way I can modify the Logger (I'm using ActiveSupport::BufferedLogger) to emit a log whenever a template is loaded?
EDIT: The reason why I ask this is that I am refactoring the code and an exception is being raised from the template code. Due to that there is no stack trace available and I am not able to figure out where exactly the error is being raised from (more importantly, I don't know which template is being loaded).

Passing the argument of an action in link_to rails 3

I have got an action which takes in an argument it goes like this :-
def join_as_student(course)
#course = course
.........
end
I have a route for this :-
resources :courses do
member do
get :join_as_student
end
end
I want to go to this route by clicking on the route like this :-
link_to "Join",join_as_student_course_path(:course => #course)
However this gives me error wrong number of arguments (0 for 1) in join_as_student action
How do I pass the argument of this action in the link_to ??

Thanks
Sorry, I missed. You can't pass params for action. use
link_to "Join",join_as_student_course_path(#course)
and
def join_as_student
#course = Course.find params[:id]
.........
end
Try
link_to "Join",join_as_student_course_path(#course)

'Nesting too deep' error while retrieving JSON using HTTParty

I am writing a very simple proxy wrapper for the reddit api so I can make cross domain JSONP requests (reddit does not allow JSONP calls to my knowledge).
I am using the HTTParty gem to make the call out and retrieve the response, which I immediately render out as json.
I am retrieving the subreddit json perfectly fine so far with this as my route:
match "r/:name" => "api#subreddit"
... and this as my controller action:
def subreddit
render :json => HTTParty.get("http://www.reddit.com/r/" + params[:name] + "/.json"), :callback => params[:callback]
end
As an example, the JSON that comes back is similar to this: http://www.reddit.com/r/pics/.json
My problem is when I attempt to grab the comments for a particular thread.
My route is as so:
match "r/:name/comments/:id" => "api#comments"
... and my controller action is this:
def comments
render :json => HTTParty.get("http://www.reddit.com/r/" + params[:name] + "/comments/" + params[:id] + "/.json"), :callback => params[:callback]
end
The JSON that I want back can be seen here: http://www.reddit.com/r/pics/comments/rhzgc/.json
When I call this action, however, I receive the following error message:
MultiJson::DecodeError in ApiController#comments
Nesting of 20 is too deep

What am I doing wrong here? If the JSON is too big to parse (I find that sort of hard to believe!) what can I do?
EDIT:
Looks like dropping back to the standard NET::HTTP lib solved my problem:
uri = URI.parse("http://www.reddit.com/r/pics/comments/rhzgc/.json")
response = Net::HTTP.get_response(uri)
render :json => response.body, :callback => params[:callback]
#OK!
... but I still am curious why I am failing this same call with HTTParty!
Thanks for the help!
It's not that the JSON is too large. It's nested too deeply. HTTParty tries to decode the results that it gets automatically. Following your stack trace, and the HTTParty dependencies, it relies on multi_json which is using the json gem.
Inside of json there is lib/json/pure/parser.rb. The default max depth set is set in there, specifically on line 79. Something in your returned JSON is 20+ levels deep, triggering the exception.
if !opts.key?(:max_nesting) # defaults to 19
#max_nesting = 19
Switched to the OJ JSON parser by adding the following to my Gemfile:
gem 'oj'
and this issue resolved itself.
It looks like this can be worked around by calling to_json with the max_nesting option set.
json = obj.to_json(max_nesting: 50)

Error with OAuth2 gem v 0.5.0

I get a very opaque error with the following code:
client = OAuth2::Client.new(
"#{FACEBOOK_CONFIG['application_id']}", "#{FACEBOOK_CONFIG['secret_key']}",
:site => 'https://graph.facebook.com'
)
token = OAuth2::AccessToken.new(client, fb_token)
token.get('/me')
when I execute token.get('/me'), I get the following output:
OAuth2::Error Exception: OAuth2::Error
This code works fine with v0.4.1 but fails with v0.5.0

I've only used Omniauth recently but it looks like your trace is saying you have something like this in your oauth_helper:
def try_access_token
begin
..
rescue OAuth2::AccessDenied
end
end
If that's the case, try changing OAuth2::AccessDenied to OAuth2::Error. Oauth2::Error provides a .code attribute that you can check to determine if it's an access denied response.
4.1 docs: http://rubydoc.info/gems/oauth2/0.4.1/frames
5.0+ docs: http://rubydoc.info/gems/oauth2/0.5.0/frames
I have the same problem.
Looking at the gem code, it's because the Facebook answer is an HTTP code of 400..599.
when 400..599
e = Error.new(response)
raise e if opts[:raise_errors] || options[:raise_errors]
Sadly, the communication between my server to facebook is using HTTPS, therefore, I haven't been able to intercept the problematic request yet.
UPDATE
I got a 400 error from Facebook :
OAuth "Facebook Platform" "invalid_request" "An active access token must be used to query information about the current user."
UPDATE 2
Interesting discussion here : Facebook access_token invalid?
I ended up rolling oauth2 back to 0.4.1 and my FB login and querying works.
