  • Get user email address with Facebooker?

    - by Kunal Dua
    I know the user needs to give the application "extended permission" for access to the email address. I went through the Facebooker documentation (I am using it for an iFrame app for whatever it's worth) but can't find any related stuff in the documentation or any sample code.

  • Routing is using ID has action and action has ID after submitting a form

    - by Victor Martins
    I have a model User that has_one user_profile and a User_Profile belongs_to user in the User controller I have: def personal @user = User.find_by_id(params[:id]) @user_profile = @user.user_profile @user_profile ||= @user.build_user_profile end def update_personal @user = User.find_by_id(params[:id]) if @user.user_profile.update_attributes(params[:user_profile]) flash[:notice] = "OK" redirect_to @user else flash[:notice] = "Fail" render :action => 'update_personal' end end In my personal.html.erb view I have: <% semantic_form_for @user_profile, :url => { :action => "update_personal"} do |form| %> <%= form.inputs %> <%= form.buttons %> <%end%> And on the rountes I have: map.resources :users, :member => { :personal => :get, :update_personal => :put } Now the strange thing is that I can do: users/1/personal to see the form but when I submit I get this error: Unknown action No action responded to 1. It's trying to find an action with the name 1. Can anyone point me out on the right direction?

  • Pushing app to heroku problem

    - by Ryan Max
    Hi, I am trying to push my app to heroku and I get the following message: $ heroku create Creating electric-meadow-15..... done Created http://electric-meadow-15.heroku.com/ | [email protected]:electric-meadow-1 5.git $ git push heroku master ! No such app as fierce-fog-63 fatal: The remote end hung up unexpectedly It's weird that I am getting this now, I have pushed the app to heroku many times without issue. the especially weird thing is, fierce-fog-63 is an old app that I made a deleted a long time ago. Why is it now that heroku is trying to push to this app that doesn't exist anymore, especially when I have created a new one. Any suggestions?

  • Python or Ruby for webbased Artificial Intelligence?

    - by Pieter Kubben
    A new web application may require adding Artificial Intelligence (AI) in the future, e.g. using ProLog. I know it can be done from a Java environment, but I am wondering about the opportunities with modern web languages like Ruby or Python. The latter is considered to be "more scientific" (at least used in that environment), but using Google there seems to be a preliminary ProLog implementation for both. Any suggestions on modern (open source) web languages (like Python or Ruby) in combination with AI?

  • Git push origin master

    - by user306472
    I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

  • How do I find the object with the oldest updated_at column in RJS?

    - by user284194
    Hello, I'm trying to remove the object with the oldest updated_at value when the rjs is executed. page.insert_html :top, :messages, :partial => @message page[@message].visual_effect :grow page[:message_form].reset Message.old_messages.each do |m| page.remove(m.id) end page.delay(1) do page.select('.message').last.visual_effect :fade end I'm using .last in there right now, but I have a periodically_call_remote in the view that continually updates and runs the rjs above. The line: page.select('.message').last.visual_effect :fade seems to only execute the first time because after the message that is "last" fades away there's nothing recognized as "last" anymore so I figure instead of calling .last I could find the object that has the oldest updated_at time stamp and just remove that instead. I'm thinking that I probably cannot do this using page.select since it only calls on css elements. And therefore I probably don't have access to the updated_at values in the Message model. Does anyone have a suggestion on how to accomplish removing the oldest message with rjs? The messages are already automatically removed in the model as new messages are created. But I want them to fade automatically when the RJS refreshes the element.

  • Getting proper indentation using XMLBuilder in a helper

    - by Robbie
    I'm attempting to use a view helper to create some dynamic links based on if you're logged in or not. What I want returned, for sake of easy code readability, is: <ul class="right"> <li><a href="#">Login</a></li> <li><a href="#">Register</a></li> </ul> In the view helper I have this Ruby code: def loginh xm = Builder::XmlMarkup.new(:indent=>2, :margin=>4) xm.ul("class" => "right") { xm.li('class' => 'text') { xm.text("test") } } end In the view, the line that calls login helper is already indented 4 levels. Because of this, the first line gets 'skewed', so in the view I have: <%= loginh %> Which results in: <ul class="right"> <li class="text"> <text>test</text> </li> </ul> You can see it works perfectly, except for the first line. It would appear that the first line is affected by the indent before <%= loginh % is called. I can easily remedy this by removing the indentation prior to <%= loginh % - but in essence I'd be sacrificing code readability for markup readability. Which isn't what I'm looking to do. Is there any way I could remove the beginning whitespace?

  • Updating multiple divs w/ RJS/AJAX

    - by bgadoci
    I am successfully using RJS to implement AJAX on a page.replace.html create.js.rjs. I am attempting to update two locations instead of one and after watching Ryan Bates Railscast I am very close (I think) but have a problem in the syntax of my /views/likes/create.js.rjs file. Here is the situation: located at /views/likes/create.js.rjs is the following code: page.replace_html "votes_#{ @site.id }", :partial => @like page.replace_html "counter", 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) page[@like].visual_effect :highlight My problem lies in the second line. The div "counter" displays the following code in the /views/question/show.html.erb page: <div id="counter"> You have <%= 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) %> votes remaining for this question </div> From watching the screen cast I believe that my error has to do w/ the syntax of the second line. Specifically he mentions that you cannot use a local instance variable but not sure how to make the change. Thoughts?

  • How to verify the SSL connection when calling a URI?

    - by robertokl
    Hello, I am developing a web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming from CAS, so that I can guarantee that the CAS responding is the real CAS server This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in Mac OS X. When I try to reach an insecure URI, it raises an exception, and when I try to reach a secure URI, it allows me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independent of what URI I try to reach, it always raises this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificate. I hope someone can help me, or tell me about a gem that works the way I need. Thanks.

  • Get multiple records with one query

    - by Lewy
    User table: name lastname Bob Presley Jamie Cox Lucy Bush Find users q = Query.new("Bob Presley, Cox, Lucy") q.find_users => {0=>{:name=>"Bob", :lastname=>"Presley"}, 1=>{:lastname=>"Cox"}, 2=>{:name=>"Lucy"}} Question: I've got hash with few names and lastnames. I need to build Activerecord query to fetch all users from that hash. I can do object = [] hash = q.find_users hash.each do |data| #check if data[:lastname] and data[:name] exist # object << User.where(:name => ..., :lastname => ...) end But I think it is higly inefficient. How should I do this ?

  • Fragment caching

    - by red5
    I would like to fragment cache part of a page. On the view I have <% cache("saved_area") do %> . <% end -%> In the controller: def index read_fragment("saved_area") end In config/production: config.cache_store = :file_store, File.join(RAILS_ROOT, 'tmp', 'cache') The file was created in the tmp/cache directory. But I am not sure if the cache is being used in the request, since I presume there should be a line in the log stating that the cache is being used (and there is not).

  • Error processing Spree sample images - file not recognized by identify command in paperclip geometry.rb:29

    - by purpletonic
    I'm getting an error when I run the Spree sample data. It occurs when Spree tries to load in the product data, specifically the product images. Here's the error I'm getting: * Execute db:load_file loading ruby <GEM DIR>/sample/lib/tasks/../../db/sample/spree/products.rb -- Processing image: ror_tote.jpeg rake aborted! /var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-21549-2rktq1 is not recognized by the 'identify' command. <GEM DIR>/paperclip-2.7.1/lib/paperclip/geometry.rb:31:in `from_file' <GEM DIR>/spree/core/app/models/spree/image.rb:35:in `find_dimensions' I've made sure ImageMagick is installed correctly, as previously I was having problems with it. Here's the output I'm getting when running the identify command directly. $ identify Version: ImageMagick 6.7.7-6 2012-10-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenCL ... other usage info omitted ... I also used pry with the pry-debugger and put a breakpoint in geometry.rb inside of Paperclip. Here's what that section of geometry.rb looks like: # Uses ImageMagick to determing the dimensions of a file, passed in as either a # File or path. # NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be # a Tempfile object, which would be eligible for file deletion when no longer referenced. def self.from_file file file_path = file.respond_to?(:path) ? file.path : file raise(Errors::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank? geometry = begin silence_stream(STDERR) do binding.pry Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]") end rescue Cocaine::ExitStatusError "" rescue Cocaine::CommandNotFoundError => e raise Errors::CommandNotFoundError.new("Could not run the `identify` command. Please install ImageMagick.") end parse(geometry) || raise(Errors::NotIdentifiedByImageMagickError.new("#{file_path} is not recognized by the 'identify' command.")) end At the point of my binding.pry statement, the file_path variable is set to the following: file_path => "/var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-22732-1ctl1g1" I've also double checked that this exists, by opening my finder in this directory, and opened it with preview app; and also that the program can run identify by running %x{identify} in pry, and I receive the same version Version: ImageMagick 6.7.7-6 2012-10-06 Q16 as before. Removing the additional digits (is this a timestamp?) after the file extension and running the Paperclip.run command manually in Pry gives me a different error: Cocaine::ExitStatusError: Command 'identify -format %wx%h :file' returned 1. Expected 0 I've also tried manually updating the Paperclip gem in Spree to 3.0.2 and still get the same error. So, I'm not really sure what else to try. Is there still something incorrect with my ImageMagick setup?

  • Monkeypatch a model in a rake task to use a method provided by a plugin?

    - by gduquesnay.mp
    During some recent refactoring we changed how our user avatars are stored not realizing that once deployed it would affect all the existing users. So now I'm trying to write a rake task to fix this by doing something like this. namespace :fix do desc "Create associated ImageAttachment using data in the Users photo fields" task :user_avatars => :environment do class User # Paperclip has_attached_file :photo ... <paperclip stuff, styles etc> end User.all.each do |user| i = ImageAttachment.new i.photo_url = user.photo.url user.image_attachments << i end end end When I try running that though I'm getting undefined method `has_attached_file' for User:Class I'm able to do this in script/console but it seems like it can't find the paperclip plugin's methods from a rake task.

  • aws-s3 can't find xml-simple, but in gem list

    - by Dan Donaldson
    I'm transitioning to heroku, and need to have AWS-s3 connections to deal with a variety of graphics. I've installed the aws-s3 gem, but one of its dependencies is not being found: xml-simple. My belief is that this is a standard part of RoR, and it is in the gem list. When I deploy to heroku, all is fine, but on my development server, it isn't being found when the code uses it to check the existence of a graphic. It works fine from the console, using s3sh. I'm not quite sure why this is -- what do I need to check? Using OS X 10.6, on a 64 bit machine -- can this be part of it?

  • Conditional relation

    - by Lowgain
    I've got a model like this: Stem -id -etc And then I have Stemrelation -stem_id -related_stem_id -active I can get the related stems with the following relations class Stem < ActiveRecord::Base has_many :stemrelations has_many :related_stems, :through => :stemrelations end class Stemrelation < ActiveRecord::Base belongs_to :stem belongs_to :related_stem, :class_name => "Stem", :foreign_key => "related_stem_id" end But now I'd only like to get the active relations. I tried adding this to the Stem model: has_many :active_related, :through => :stemrelations, :source => :related_stem, :conditions => {:active => true} but this gives me an error becasue it tries to check the active flag on the stem model instead of the stemrelation. What do I change here? Thanks!

  • Passing hash as values in hidden_field_tag

    - by funkymunky
    I am trying to pass some filters in my params through a form like so: hidden_field_tag "filters", params[:filters] For some reason the params get changed in the next page. For example, if params[:filters] used to be... "filters"={"name_like_any"=["apple"]} [1] ...it gets changed to... "filters"="{\"name_like_any\"=[\"apple\"]}" [2] note the extra quotations and backslashes in [2] when compared to [1]. Any ideas? I'm attempting to use this with searchlogic for some filtering, but I need it to persist when I change change objects in forms. I would prefer not to have to store it in session.
