  • mongodb read/write performance and mongo hosting in the cloud

    - by z3cko
    we are currently developing a high traffic rails application with facebooker (facebook game). since amazon simpledb (aws-sdb) is really slow, we are thinking of using a dedicated mongodb server as offered by mongoHQ for example. questions: what is the read/writes peak value for a mongodb server running on a amazon ec2 instance? what would be a recommended setup for a ec2 hosted app with mongodb - a master on amazon EBS and replicas on the ec2 instances? any examples or experiences? is there a company that offers mongodb hosting in the cloud? thanks, mz

  • Ajax, Multiple Attachments and Paperclip question.

    - by dustmoo
    Alright everyone this is a bit of a complicated setup so if I need to clarify the question just let me know. I have a model: class IconSet < ActiveRecord::Base has_many :icon_graphics end This Model has many icongraphics: class IconGraphic < ActiveRecord::Base belongs_to :icon_set has_attached_file :icon has_attached_file :flagged end As you can see, IconGraphic has two attached files, basically two different versions of the icon that I want to load. Now, this setup is working okay if I edit the icongraphic's individually, however, for ease of use, I have all the icon graphics editable under the IconSet. When you edit the icon set the form loads a partial for the icongraphics: <% form_for @icon_set, :html => {:class => 'nice', :multipart => true} do |f| %> <fieldset> <%= f.error_messages %> <p> <%= f.label :name %> <%= f.text_field :name, :class => "text_input" %> </p> <!-- Loaded Partial for icongraphics --> <div id="icon_graphics"> <%= render :partial => 'icon_graphic', :collection => @icon_set.icon_graphics %> </div> <div class="add_link"> <%= link_to_function "Add an Icon" do |page| page.insert_html :bottom, :icon_graphics, :partial => 'icon_graphic', :object => IconGraphic.new end %> </div> <p><%= f.submit "Submit" %></p> </fieldset> <% end %> This is based largely off of Ryan's Complex Forms Railscast. The partial loads the file_field forms: <div class="icon_graphic"> <% fields_for "icon_set[icon_graphic_attributes][]", icon_graphic do |icon_form|-%> <%- if icon_graphic.new_record? -%> <strong>Upload Icon: </strong><%= icon_form.file_field :icon, :index => nil %><br/> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= link_to_function image_tag('remove_16.png'), "this.up('.icon_graphic').remove()"%><br/> <% else -%> <%= image_tag icon_graphic.icon.url %><br/> <strong>Replace <%= icon_graphic.icon_file_name %>: </strong><%= icon_form.file_field :icon, :index => nil %><br /> <% if icon_graphic.flagged_file_name.blank? -%> <strong>Upload Flagged Icon: </strong><%= icon_form.file_field :flagged, :index => nil %> <% else -%> <strong>Replace <%= icon_graphic.flagged_file_name %>: </strong><%= icon_form.file_field :flagged, :index => nil %> <%= icon_form.hidden_field :flagged, :index => nil %> <% end -%> <%= link_to_function image_tag('remove_16.png'), "mark_for_destroy(this, '.icon_graphic')"%><br/> <%= icon_form.hidden_field :id, :index => nil %> <%= icon_form.hidden_field :icon, :index => nil %> <%= icon_form.hidden_field :should_destroy, :index => nil, :class => 'should_destroy' %> <br/><br/> <%- end -%> <% end -%> </div> Now, this is looking fine when I add new icons, and fill both fields. However, if I edit the IconSet after the fact, and perhaps try to replace the icon with a new one, or if I uploaded only one of the set and try to add the second attachment, paperclip doesn't put the attachments with the right IconGraphic Model. It seems that even though I have the IconGraphic ID in each partial, <%= icon_form.hidden_field :id, :index => nil %> it seems that paperclip either creates a new IconGraphic or attaches it to the wrong one. This all happens when you save the IconSet, which is setup to save the IconGraphic attributes. I know this is complicated.. I may just have to go to editing each icon individually, but if anyone can help, I would appreciate it.

  • acts_as_xapian jobs table

    - by Grnbeagle
    Hi, Can someone explain to me the inner workings of acts_as_xapian_jobs table? I ran into an issue with the acts_as_xapian plugin recently, where I kept getting the following error when it creates an object with xapian indexed fields: Mysql::Error: Duplicate entry 'String-2147483647' for key 2: INSERT INTO `acts_as_xapian_jobs` (`action`, `model`, `model_id`) VALUES ('update', 'String', 23730251831560) It turns out the model_id exceeded the max int value of 2147483647. The workaround was to update model_id to use bigint. Why would the model_id be so huge? By looking at content of acts_as_xapian_jobs, it seems it creates a row for every field that is being indexed.. Understanding how a job gets created in the table would help a great deal. Here's a sampling of the table: mysql> select * from acts_as_xapian_jobs limit 5\G *************************** 1. row *************************** id: 19 model: String model_id: 23804037900560 action: update *************************** 2. row *************************** id: 49 model: String model_id: 23804037191200 action: update *************************** 3. row *************************** id: 79 model: String model_id: 23804037932180 action: update *************************** 4. row *************************** id: 109 model: String model_id: 23804037101700 action: update *************************** 5. row *************************** id: 139 model: String model_id: 23804037722160 action: update Thanks in advance, Amie

  • Prevent Rails link_to_remote multiple submits w Javascript

    - by Chris
    In a Rails project I need to keep a link_to_remote from getting double-clicked. It looks like :before and :after are my only choices - they get prepended/appended to the onclick Ajax call, respectively. But if I try something like: :before => "self.stopObserving()" t,he Ajax is never run. If I try it for :after the Ajax is run but the link never stops observing. The solutions I've seen rely on creating a variable and blocking the whole form, but there are multiple link_to_remote rows on this page and it is valid to click more than one of them at a time - just not the same one twice. One variable per row declared outside of link_to_remote seems very kludgey... Instead of using Prototype I originally tried plain Javascript first for this proof of concept - but it fails too: <a href="#" onclick="self.onclick = function(){alert('foo');};"click</a just puts up an alert when clicked - the lambda here does nothing? This next one is more like the desired goal and should only alert the first time. But instead it alerts every time: <a href="#" onclick="alert('bar'); self.onclick = function(){return false;};"click</a All ideas appreciated!

  • Formatting Parameters for Ajax POST request to Rails Controller - for jQuery-UI sortable list

    - by Hung Luu
    I'm using the jQuery-UI Sortable Connected Lists. I'm saving the order of the connected lists to a Rails server. My approach is to grab the list ID, column ID and index position of each list item. I want to then wrap this into an object that can be passed as a parameter back to the Rails Controller to be saved into the database. So ideally i'm looking to format the parameter like this: Parameters: {"Activity"=>[{id:1,column:2,position:1},{id:2,column:2,position:2} ,...]} How do I properly format my parameters to be passed in this Ajax POST request? Right now, with the approach below, I'm passing on Parameters: {"undefined"=>""} This is my current jQuery code (Coffeescript) which doesn't work: jQuery -> $('[id*="day"]').sortable( connectWith: ".day" placeholder: "ui-state-highlight" update: (event, ui) -> neworder = new Array() $('[id*="day"] > li').each -> column = $(this).attr("id") index = ui.item.index() + 1 id = $("#" + column + " li:nth-child(" + index + ") ").attr('id') passObject={} passObject.id = id passObject.column = column passObject.index = index neworder.push(passObject) alert neworder $.ajax url: "sort" type: "POST" data: neworder ).disableSelection() My apologies because this seems like a really amateur question but I'm just getting started with programming jQuery and Javascript.

  • adding visual effects to RJS before action rendered

    - by Sam
    I just started using RJS which is awesome however I am used to putting visual effects in the link_to_remote and such and I'm not sure how to trigger actions before and after remotes are triggered. Take this link for example: HTML <span id="<%= "edit_comment_link_#{comment.id.to_s}"%>" style="float:left;"> <%= link_to_remote "edit", {:update => "comment_#{comment.id.to_s}", :url => edit_post_comment_path(comment.post, comment), :method => :get}%> | </span> Controller: def edit @comment = Comment.find(params[:id]) respond_to do |format| #format.html render edit_comment_path(@comment) format.js end end RJS: page.replace_html "edit_comment_link_#{@comment.id.to_s}", "currently editing | " So is RJS mainly for after actions are rendered visual effects such as a spinner should be put into the link_to_remote with call_backs? Is this a good way of doing things?

  • Mongomapper - unit testing with shoulda on rails 2.3.5

    - by egarcia
    I'm trying to implement shoulda unit tests on a rails 2.3.5 app using mongomapper. So far I've: Configured a rails app that uses mongomapper (the app works) Added shoulda to my gems, and installed it with rake gems:install Added config.frameworks -= [ :active_record, :active_resource ] to config/environment.rb so ActiveRecord isn't used. My models look like this: class Account include MongoMapper::Document key :name, String, :required => true key :description, String key :company_id, ObjectId key :_type, String belongs_to :company many :operations end My test for that model is this one: class AccountTest < Test::Unit::TestCase should_belong_to :company should_have_many :operations should_validate_presence_of :name end It fails on the first should_belong_to: ./test/unit/account_test.rb:3: undefined method `should_belong_to' for AccountTest:Class (NoMethodError) Any ideas why this doesn't work? Should I try something different from shoulda? I must point out that this is the first time I try to use shoulda, and I'm pretty new to testing itself.

  • How to restrict text search to a certain subset of the database ?

    - by Nikhil Garg
    I have a large central database of around 1 million heavy records. In my app, for every user I would have a subset of rows from central table, which would be very small (probably 100 records each).When a particular user has logged in , I would want to search on this data set only. Example: Say I have a central database of all cars in the world. I have a user profile for General Motors(GM) , Ferrari etc. When GM is logged in I just want to search(a full text search and not fire a sql query) for those cars which are manufactured by GM. Also GM may launch/withdraw a model in which case central db would be updated & so would be rowset associated with GM. In case of acquisitions, db of certain profiles may change without launch/removal of new car. So central db wont change then , but rowsets may. Whats the best way to implement such a design ? These smaller row sets would need to be dynamic depending on user activities. We are on Rails 2.3.5 and use thinking_sphinx as the connector and Sphinx/MySQL for search and relational associations.

  • Why is Rails is trying to rerun migrations on production?

    - by ryeguy
    On my server when deploying the app for the first time, I ran rake db:setup which loads my entire migration history from schema.rb. Now I have more stuff I want to add, but when I run rake db:migrate on my server I realize it's trying to run my very first migration, which is failing since the table obviously exists. Examining the schema_migrations table on my production server, I realize it only has one entry in it, which is the migration that was the most current at the time of the initial deployment. Isn't it supposed to have the entire migration history in it? If so, what caused this? If not, why is it doing this?

  • How to cache pages using background jobs ?

    - by Alexandre
    Definitions: resource = collection of database records, regeneration = processing these records and outputting the corresponding html Current flow: Receive client request Check for resource in cache If not in cache or cache expired, regenerate Return result The problem is that the regeneration step can tie up a single server process for 10-15 seconds. If a couple of users request the same resource, that could result in a couple of processes regenerating the exact same resource simultaneously, each taking up 10-15 seconds. Wouldn't it be preferrable to have the frontend signal some background process saying "Hey, regenerate this resource for me". But then what would it display to the user? "Rebuilding" is not acceptable. All resources would have to be in cache ahead of time. This could be a problem as the database would almost be duplicated on the filesystem (too big to fit in memory). Is there a way to avoid this? Not ideal, but it seems like the only way out. But then there's one more problem. How to keep the same two processes from requesting the regeneration of a resource at the same time? The background process could be regenerating the resource when a frontend asks for the regeneration of the same resource. I'm using PHP and the Zend Framework just in case someone wants to offer a platform-specific solution. Not that it matters though - I think this problem applies to any language/framework. Thanks!

  • Rspec Selenium. Test to check certain Ajax functions passes when i expect it to fail.

    - by alokswain
    I am testing a Ajax action using Rspec and Selenium. My story is as follows: it "should create a new User with any input" do @browser.open "/people" @browser.wait_for_page_to_load "2000" @browser.type "user_name", "Alok Swain" @browser.click "user_submit" @browser.text?("Alok Swain").should be_true end The action i am testing is: def add_user @users = User.all User.create(params[:user]) render :update do |page| page.alert "Created User" page.replace_html "users", :partial => '/people/users_list', :locals => {:users => @users} end end The test fails and the error I get is: 'User should create a new User with any input' FAILED expected false to be true. This test should pass right ? I also kept an alert and tried @browser.is_alert_present.should be_true but i got the same error. I tried @browser.is_text_present("test") and this test succeeded. In the test database a record was created for Alok Swain but when I tried the above assertion it passed when i expected it to fail. Is there any thing else to be done here. What am I missing ?

    I have a silverlight application that needs to talk to a rails app to add a record. I have been able to get the silverlight app to successfully do the POST assuming everything goes good. Now, however, I need to be able to make it more robust and have the rails app return error/success messages to the silverlight app in a format it can read (xml maybe?). I can modify the rails app and silverlight app as needed. What is the best way to accomplish this with rails?

  • Securely persist session between https://secure.yourname.com and http://www.yourname.com on rails ap

    - by Matt
    My rails site posts to a secure host (e.g. 'https://secure.yourname.com') when the user logs into the site. Session data is stored in the database, with the cookie containing only the session ID. The problem is that when the user returns to a non-https page, such as the home page (e.g. 'http://www.yourname.com') the user appears to have logged out. I believe the reason for this is that a separate cookie is stored for each host (www vs. secure). Is this correct? What is the best secure way to persist the session between both the http and https sections of the site? Does anyone know of any plugins that address this problem? The site runs on Heroku.

  • Amazon access key showing in URL for Carrierwave and Fog

    - by kcurtin
    I just switched from storing my images uploaded via Carrierwave locally to using Amazon s3 via the fog gem in my Rails 3.1 app. While images are being added, when I click on an image in my application, the URL is providing my access key and a signature. Here is a sample URL (XXX replaced the string with the info): https://s3.amazonaws.com/bucketname/uploads/photo/image/2/IMG_4842.jpg?AWSAccessKeyId=XXX&Signature=XXX%3D&Expires=1332093418 This is happening in development (localhost:3000) and when I am using heroku for production. Here is my uploader: class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick storage :fog def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end process :convert => :jpg process :resize_to_limit => [640, 640] version :thumb do process :convert => :jpg process :resize_to_fill => [280, 205] end version :avatar do process :convert => :jpg process :resize_to_fill => [120, 120] end end And my config/initializers/fog.rb : CarrierWave.configure do |config| config.fog_credentials = { :provider => 'AWS', :aws_access_key_id => 'XXX', :aws_secret_access_key => 'XXX', } config.fog_directory = 'bucketname' config.fog_public = false end Anyone know how to make sure this information isn't available?

  • Eclipse users: Do you use Aptana too?

    - by Glenn
    This San Mateo development company makes a freely downloadable convenient packaging of many plugins for Eclipse called Aptana. I was recently in an environment where Aptana came pre-installed. Not only is it a good IDE for RoR, it also does a somewhat decent job (sans debugging) for PHP, Python, HTML, CSS, and Javascript. According to their own web site, their IDE also supports Adobe Air and the iPhone. If you are currently using Eclipse, then do you also use Aptana too? What, if any, are the drawbacks to using Aptana?

  • What do you use for recurring payments in a Rails Application?

    - by Chance
    I'm fairly new to rails so I'm definitely not up to speed on the community's best practices, tools, etc. So I figure this may be the best place to ask. What do you use for recurring billing in a rails app? From what I can tell, there are a number of options including rolling my own with ActiveMerchant or using one of the SaaS out there. As far as the SaaS recurring billing systems, I've only stumbled upon one thus far (chedder getter) and I'm hoping there are alternatives (if, for nothing else, so I can compare). Additionally, I've seen a few invoice systems but they either do not handle the payment portion, do not seem to fit well with the intention, or are extremely outdated. Thanks in advance!
