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:
Started DELETE "/services/appeals" for 127.0.0.1 at 2016-12-21 11:08:42 -0500

BSON::InvalidObjectId (illegal ObjectId format: appeals):
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.

It's another developers application that I'm trying to get working correctly again. I'm not very experienced with Ruby, Rails, or MongoDB.

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.

I'm pretty new in Rails and on stackoverflow so I'll try to be explicite.
I was asking to change someone project, so I get the sources and try to make it works on
my own work computer (that's on Windows ...) to test it on my local browser (cf : rails s). The project is suppose to be working because it's already in production, so I assume that the problem come from my own work environment.
After installing all the needed gems, run bundle install and launch database serveur (the project is using mongodb), I run rails server. The command actually works but as soon as I try to connect on the application with any browser on the localhost adress (http://localhost:3000/) I get an error and I reaaly don't understand the cause...
This is the log I get :

And this is the controller that's mentionned :
class HomeController < ApplicationController
def index
#presenter = Home::IndexPresenter.new
#article_presenter = Articles::IndexPresenter.new(Article.with_state(:published).last)
end
end
If someone could help me it would be very kind. Ask if I forgot to mention something.
Thanks you.
The root problem is that the URL being requested by rest_client is returning the HTTP 406 code, which you can see by running curl, e.g.
curl --include https://api.localeapp.com/v1/projects/hhMxHgKAzj9p1dFuS0GnTTnemJ5F9dXLDuCa1KacQSymUcmTFk/translations.yml?updated_at=1354612995
(I just noticed that you are on a windows environment -- if you don't have access to curl there are several tools you can install that will allow you to make requests)
Then, within your controller, there doesn't appear to be any check to see if the response from the RestClient call was successful (2xx status) or not. Because RestClient raises an exception, you get a 500 error in your application.
So, if you're not sure why the URL is not working, then you'll need to check the API provided by localeapp.com
But given that the API is an external service, you may also want to add some error handling within your software. There are several things out there known as RestClient, but if it's by archiloque, the documentation provides a good example of "result handling" here.
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).

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)
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)
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
