  • How to copy this portion of a text file out and put into a hash using rails? (VATsim datafile)

    - by Rusty Broderick
    Hi I'm trying to work out how i can cut out the section between !CLIENTS and the '; ;' and then to parse it into a hash in order to make an xml file. Honestly have no idea how to do it. The file is as follows: vatsim-data.txt original file here ; Created at 30/12/2010 01:29:14 UTC by Data Server V4.0 ; ; Data is the property of VATSIM.net and is not to be used for commercial purposes without the express written permission of the VATSIM.net Founders or their designated agent(s ). ; ; Sections are: ; !GENERAL contains general settings ; !CLIENTS contains informations about all connected clients ; !PREFILE contains informations about all prefiled flight plans ; !SERVERS contains a list of all FSD running servers to which clients can connect ; !VOICE SERVERS contains a list of all running voice servers that clients can use ; ; Data formats of various sections are: ; !GENERAL section - VERSION is this data format version ; RELOAD is time in minutes this file will be updated ; UPDATE is the last date and time this file has been updated.

  • Why is the proper "respond_to" format not getting called?

    - by humble_coder
    Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

  • Using twitter gem to signup and authenticate users

    - by Jim Jones
    Hi, I'd like to allow users the option to register using their Twitter account. Basically, I'll present them with a standard signup form (name, login, email, pwd, pwd_confirm) as well as a "Signup with Twitter" link. If a user chooses to signup with Twitter creds, then I'll create a user record in db. Then I'd like to be able to allow a user to authenticate using their Twitter creds on returning visits. Also, I'm using restful_authentication, so I need to have this work within that context. What is the best way to do this? I haven't been to find any tutorials on allowing the signup and authentication pieces. Most examples just show how to authenticate a Twitter user into your app. Thanks.

  • Auto update CSS from SASS/SCSS in Rails?

    - by Vulgrin
    Maybe I'm confused on how SASS/SCSS works within Rails (2.3.8.) but I was under the impression that if I included the option Sass::Plugin.options[:always_update] = true that whenever I changed my SCSS file and then hit the page (controller) again, the SCSS would recompile. I can't seem to get this to work, and can't seem to find a good tutorial / example for it. I've tried setting the above property in the Environment.rb file, but it didn't seem to do anything. I tried putting it in its own initializer with require 'sass' but that doesn't seem to work either. What am I missing? Or am i just forced to keep a terminal open with a sass --watch command running to be able to rapidly debug / change my styles? thx

  • how do I get foreign_key to work in this simple has_many, belongs_to relationship?

    - by rpflo
    I'm pulling data from Harvest. Here are my two models and schema: # schema create_table "clients", :force => true do |t| t.string "name" t.integer "harvest_id" end create_table "projects", :force => true do |t| t.string "name" t.integer "client_id" t.integer "harvest_id" end # Client.rb has_many :projects, :foreign_key => 'client_id' # not needed, I know # Project.rb belongs_to :client, :foreign_key => 'harvest_id' I'm trying to get the Projects to find their client by matching Project.client_id to a Client.harvest_id. Here is what I'm getting instead. > Project.first.client_id => 187259 Project.first.client => nil Client.find(187259).projects => [] Is this possible? Thanks!

  • Rails 3 query in multiple date ranges

    - by NeoRiddle
    Suppose we have some date ranges, for example: ranges = [ [(12.months.ago)..(8.months.ago)], [(7.months.ago)..(6.months.ago)], [(5.months.ago)..(4.months.ago)], [(3.months.ago)..(2.months.ago)], [(1.month.ago)..(15.days.ago)] ] and a Post model with :created_at attribute. I want to find posts where created_at value is in this range, so the goal is to create a query like: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06' OR BETWEEN '2011-09-06' AND '2011-10-06' OR BETWEEN '2011-11-06' AND '2011-12-06' OR BETWEEN '2012-01-06' AND '2012-02-06' OR BETWEEN '2012-02-06' AND '2012-03-23'; If you have only one range like this: range = (12.months.ago)..(8.months.ago) we can do this query: Post.where(:created_at => range) and query should be: SELECT * FROM posts WHERE created_at BETWEEN '2011-04-06' AND '2011-08-06'; Is there a way to make this query using a notation like this Post.where(:created_at => range)? And what is the correct way to build this query? Thank you

  • gem install cannot find a header file

    - by Milktrader
    Following along the github README for talib_ruby: sudo port install ta-lib Complete. Next is where the trouble begins. sudo env ARCHFLAGS="-arch PLATFORM" gem install talib_ruby -- --with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS --with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS This install fails I believe because apparently it cannot find the ta_abstract.h file talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors I have included in my .bash_profile file the following: export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib And indeed the ta_abstract.h file is located where I'm saying in the ABSOLUTE_PATH variable assignment. What gives?

What's the best way to achieve this?

  • rails named_scope issue with eager loading

    - by Craig
    Two models (Rails 2.3.8): User; username & disabled properties; User has_one :profile Profile; full_name & hidden properties I am trying to create a named_scope that eliminate the disabled=1 and hidden=1 User-Profiles. Moreover, while the User model is usually used in conjunction with the Profile model, I would like the flexibility to be able specify this using the :include = :profile syntax. I have the following User named_scope: named_scope :visible, { :joins => "INNER JOIN profiles ON users.id=profiles.user_id", :conditions => ["users.disabled = ? AND profiles.hidden = ?", false, false] } This works as expected when just reference the User model: >> User.visible.map(&:username).flatten => ["user a", "user b", "user c", "user d"] However, when I attempt to include the Profile model: User.visible(:include=> :profiles).profile.map(&:full_name).flatten I get an error that reads: NoMethodError: undefined method `profile' for #<User:0x1030bc828> Am I able to cross model-collection boundaries in this manner?

  • RSpec: Expectation on model's not working while testing controller

    - by gmile
    I'm trying to write a functional test. My test looks as following: describe PostsController do it "should create a Post" do Post.should_receive(:new).once post :create, { :post => { :caption => "ThePost", :category => "MyCategory" } } end end My PostsController (a part of it actually) looks as following: PostController < ActiveRecord::Base def create @post = Post.new(params[:post]) end end Running the test I'm always receiving a failure, which says that the Post class expected :new but never got it. Still, the actual post is created. I'm a newbie to RSpec. Am I missing something?

  • Redirecting users after destroy

    - by mathee
    I have 3 models: Questions, Answers, and Profiles (I know, it should be called "Users"). When you view a question Q, I query the database for the answers to Q. (They are linked by id.) In the view, the current user has the option to delete his answer by clicking on the destroy link displayed next to his answer: %table %tr %td Answers: - @answers.each do |a| %tr %td - @provider = Profile.find(a.provider) %i #{h @provider.username} said: %br #{h a.description} %td = link_to 'View full answer', a %td - if a.provider == @profile.id #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :method => :delete} The problem is that when the user clicks on the destroy link, it redirects to the /answers/index. I want it to redirect to /questions/Q. What's the best way to do this? I know that there's a redirect_to method, but I don't know how to implement it when I want to redirect to an action for a different controller. It also needs to remember the question from which the answer is being deleted. I tried passing something like :question_id in link_to as: #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :question_id => @question.id, :method => :delete} In AnswersController#destroy: def destroy @answer = Answer.find(params[:id]) @answer.destroy respond_to do |format| format.html { redirect_to(answers_url) } format.xml { head :ok } end @question = Question.find(params[:question_id]) redirect_to question_path(@question) end The :question_id information is not passed to the destroy method, so I get this error: Couldn't find Question without an ID To confirm, I added a puts call before Question.find, and it returned nil.

  • Using fields from an association (has_many) model with formtastic in rails

    - by pduersteler
    I searched and tried a lot, but I can't accomplish it as I want.. so here's my problem. class Moving < ActiveRecord::Base has_many :movingresources, :dependent => :destroy has_many :resources, :through => :movingresources end class Movingresource < ActiveRecord::Base belongs_to :moving belongs_to :resource end class Resource < ActiveRecord::Base has_many :movingresources has_many :movings, :through => :movingresources end Movingresources contains additional fields, like "quantity". We're working on the views for 'bill'. Thanks to formtastic to simplify the whole relationship thing by just writing <%= form.input :workers, :as => :check_boxes %> and i get a real nice checkbox list. But what I haven't found out so far is: How can i use the additional fields from 'movingresource', next or under each checkbox my desired fields from that model? I saw different approaches, mainly with manually looping through an array of objects and creating the appropriate forms, using :for in a form.inputs part, or not. But none of those solutions were clean (e.g. worked for the edit view but not for new because the required objects were not built or generated and generating them caused a mess). I want to know your solutions for this! :-)

  • Staring Shotgun with Thin as server using SSL

    - by Bryan Paronto
    I have a Facebook app I'm developing locally. I've configure everything correctly to SSL development with Thin. I know that using a shotgun.rb file, I can pass options to Thin to get it to start in SSL mode, but I'm not exact sure how to pass these options. I'm thinking something like: Thin:Server::options[:ssl] = true Thin:Server::options[:ssl_cert_path] = /path/to/cert/ Restarting thin constantly is getting old, so I'd really like to be able to use shotgun in development.

  • named_scope + average is causing the table to be specified more then once in the sql query run on po

    - by hadees
    I have a named scopes like so... named_scope :gender, lambda { |gender| { :joins => {:survey_session => :profile }, :conditions => { :survey_sessions => { :profiles => { :gender => gender } } } } } and when I call it everything works fine. I also have this average method I call... Answer.average(:rating, :include => {:survey_session => :profile}, :group => "profiles.career") which also works fine if I call it like that. However if I were to call it like so... Answer.gender('m').average(:rating, :include => {:survey_session => :profile}, :group => "profiles.career") I get... ActiveRecord::StatementInvalid: PGError: ERROR: table name "profiles" specified more than once : SELECT avg("answers".rating) AS avg_rating, profiles.career AS profiles_career FROM "answers" LEFT OUTER JOIN "survey_sessions" survey_sessions_answers ON "survey_sessions_answers".id = "answers".survey_session_id LEFT OUTER JOIN "profiles" ON "profiles".id = "survey_sessions_answers".profile_id INNER JOIN "survey_sessions" ON "survey_sessions".id = "answers".survey_session_id INNER JOIN "profiles" ON "profiles".id = "survey_sessions".profile_id WHERE ("profiles"."gender" = E'm') GROUP BY profiles.career Which is a little hard to read but says I'm including the table profiles twice. If I were to just remove the include from average it works but it isn't really practical because average is actually being called inside a method which gets passed the scoped. So there is some times gender or average might get called with out each other and if either was missing the profile include it wouldn't work. So either I need to know how to fix this apparent bug in Rails or figure out a way to know what scopes were applied to a ActiveRecord::NamedScope::Scope object so that I could check to see if they have been applied and if not add the include for average.

  • Can 'locals' be used with 'collection' when rendering partials in Rails?

    - by Gav
    Everything works okay when I try to render a partial like this: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types However, if I also want to pass a variable (in this case 'path', because I'm sharing this partial across two forms), the path is not available to me: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types, :locals => {:path => customers_enquiry_path} I've tried moving things around, but nothing appears to work, leading me to believe one cannot use locals with collections. Any help would be appreciated. Gav

  • Autotest notifications on Ubuntu virtual environment

    - by Luciano
    I am having trouble getting Rails autotest notifications to work on the Engine Yard Vagrant environment. On the Mac, I normally get the notifications via Growl. However, on the virtual environment (which runs Ubuntu) that doesn't work. I tried running Linux notification setups such as libnotify+autotest-notification, but I get the following error: libnotify-Message: Unable to get session bus: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_call: assertion `DBUS_IS_G_PROXY (proxy)' failed Another path would be to have Growl receive the notifications remotely, but I don't even know where to begin with that... Any suggestions?

  • Polymorphic :has_many, :through as module in Rails 3.1 plugin

    - by JohnMetta
    I've search everywhere for a pointer to this, but can't find one. Basically, I want to do what everyone else wants to do when they create a polymorphic relationship in a :has_many, :through way… but I want to do it in a module. I keep getting stuck and think I must be overlooking something simple. To wit: module ActsPermissive module PermissiveUser def self.included(base) base.extend ClassMethods end module ClassMethods def acts_permissive has_many :ownables has_many :owned_circles, :through => :ownables end end end class PermissiveCircle < ActiveRecord::Base belongs_to :ownable, :polymorphic => true end end With a migration that looks like this: create_table :permissive_circles do |t| t.string :ownable_type t.integer :ownable_id t.timestamps end The idea, of course, is that whatever loads acts_permissive will be able to have a list of circles that it owns. For simple tests, I have it "should have a list of circles" do user = Factory :user user.owned_circles.should be_an_instance_of Array end which fails with: Failure/Error: @user.circles.should be_an_instance_of Array NameError: uninitialized constant User::Ownable I've tried: using :class_name => 'ActsPermissive::PermissiveCircle' on the has_many :ownables line, which fails with: Failure/Error: @user.circles.should be_an_instance_of Array ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source association(s) :owned_circle or :owned_circles in model ActsPermissive::PermissiveCircle. Try 'has_many :owned_circles, :through => :ownables, :source => <name>'. Is it one of :ownable? while following the suggestion and setting :source => :ownable fails with Failure/Error: @user.circles.should be_an_instance_of Array ActiveRecord::HasManyThroughAssociationPolymorphicSourceError: Cannot have a has_many :through association 'User#owned_circles' on the polymorphic object 'Ownable#ownable' Which seems to suggest that doing things with a non-polymorphic-through is necessary. So I added a circle_owner class similar to the setup here: module ActsPermissive class CircleOwner < ActiveRecord::Base belongs_to :permissive_circle belongs_to :ownable, :polymorphic => true end module PermissiveUser def self.included(base) base.extend ClassMethods end module ClassMethods def acts_permissive has_many :circle_owners, :as => :ownable has_many :circles, :through => :circle_owners, :source => :ownable, :class_name => 'ActsPermissive::PermissiveCircle' end end class PermissiveCircle < ActiveRecord::Base has_many :circle_owners end end With a migration: create_table :permissive_circles do |t| t.string :name t.string :guid t.timestamps end create_table :circle_owner do |t| t.string :ownable_type t.string :ownable_id t.integer :permissive_circle_id end which still fails with: Failure/Error: @user.circles.should be_an_instance_of Array NameError: uninitialized constant User::CircleOwner Which brings us back to the beginning. How can I do what seems to be a rather common polymorphic :has_many, :through on a module? Alternatively, is there a good way to allow an object to be collected by arbitrary objects in a similar way that will work with a module?

  • Workling processes multiplying uncontrolably

    - by adam
    Hello there. We have a rails app running on passenger and we background process some tasks using a combination of RabbitMQ and Workling. The workling's worker process is started using the script/workling_client command. There is always only one worker process started, and the script/workling_client has a :multiple => false options, thus allowing only one instance. But sometimes, under mysterious circumstances which I haven't been able to track down, more worklings spawn up. If I let the system run for some time, more and more worklings appear. I'm not sure if these rogue worklings cause any problems, but it is still unsettling not to know why is it happening. We are using Monit to monitor the workling process. So if it dies, it will spawn it up again. But this still does not explain how come there are suddenly more than one of them. So my question is: does anyone know what can be cause of this and how to make it stop? Is it possible that workling sometimes dies by itself, without deleting it's pid file? Could there be something wrong with the Daemons gem workling_client is build upon?
