  • Projects integration question

    - by qkrsppopcmpt
    Other team has one legacy system, which is data aggregators. It is implemented as web service using JAVA, SOAP,MTOM,Tomcat and Axis2. They have wsdl files defining functionalities such as search, retrieve data, upload, download. Our team has a new developed website which is developed using RoR with mySQL. It is sort of social networking. Users can register, add friends, upload images, videos. Also, they can search data. We are required to connect the two systems. One possible solution I think is - Adding components into our website. The component invoke services on the aggregators. - Synchronize website database to the aggregators. My doubts are: 1. How to add components in our websites? The components should use Java or Ruby or adapter from java to ruby. It is possible using ruby invoke web service. I think it should work since it is the point of web service. If so, can ruby call those services in wsdl directly? But how to deal with those different data structure? How to synchroinze our database to the aggregators. I think the best way is also through web service invocation such as upload. That means, we have to export the db records into xml files and then write some tools to upload. The web service project support MTOM. So, it is fine to upload huge data. Am I on the right record? Can anybody give me some hint. Thanks.

  • Creating an additional related model with Devise

    - by Tim Sullivan
    I've started to implement a new project using Devise, which is pretty fantastic for handling users. However, when a user signs up, they're not just creating a User model, but also need to create a related Account model that represents the company. Additional users will also belongs_to this Account model. I can't seem to find a hook for this in Devise, though it seems like a pretty common pattern. What's the best practice for this?

  • how to give 2 parameters to remote_function thanks to 'with' ???

    - by bahamut100
    Hi, I try to give a lot of parameters in a remote_function like this : <?php echo remote_function(array( 'update' => 'test', 'url' => 'conges/verifdate', 'with' => "'date_deb=' + $('date_debut').value" )); ?> This code works, in my action.class I can to get the parameter. But when I try to give a second parameter, it doesn't work : <?php echo remote_function(array( 'update' => 'test', 'url' => 'conges/verifdate', 'with' => "'date_deb=' + $('date_debut').value"."'+&date_fin=' + $('date_fin')" )) ?> Why ??

  • Getting list of states/events from a model that AASM's

    - by Jason Nerer
    Hi, I successfully integrated the most recent AASM gem into an application, using it for the creation of a wizard. In my case I have a model order class Order < ActiveRecord::Base belongs_to :user has_one :billing_plan, :dependent => :destroy named_scope :with_user, ..... <snip> include AASM aasm_column :aasm_state aasm_initial_state :unauthenticated_user aasm_state :unauthenticated_user, :after_exit => [:set_state_completed] aasm_state : <snip> <and following the event definitions> end Now I would like to give an administrator the possibility to create his own graphs through the AASM states. Therefore I created two additional models called OrderFlow and Transition where there order_flow has many transitions and order belongs_to order_flow. No problem so far. Now I would like to give my admin the possibility to dynamically add existing transitions / events to an order_flow graph. The problem now is, that I do not find any possibility to get a list of all events / transitions out of my order model. aasm_states_for_select seems to be the correct candidate, but I cannot call it on my order model. Can anyone help? Thx in advance. J.

  • Counting distinct and duplicate attribute values in an array

    - by keruilin
    I have an array of users that's sorted in descending order based on total_points. I need to find the rank of each user in that array. The issue is that more than one user can have the same total points and, thus, the same rank. For example, three users could be in 3rd place with 200 Points. Here's my current code: class Leader < ActiveRecord::Base def self.points_leaders all_leaders = all_points_leaders # returns array of users sorted by total_points in desc order all_leaders_with_rank = [] all_leaders.each do |user| rank = all_leaders.index(user)+1 all_leaders_with_rank << Ldr.new(rank, user) # Ldr is a Struct end return all_leaders_with_rank end end How must I modify the code so that the correct rank is returned, and not just the value of the index position?

  • javascript to determine if page on remote domain has changed

    - by uku
    Hi, I am trying to find a client-side way to determine if a page on a remote domain has changed. I can't load the page in an iframe and examine its contents due to same origin policy. So I tried using .getResponseHeader("Content-Length") and .getResponseHeader("Last-Modified") but apparently these are also restricted by SOP even though FireBug shows Content-Length in the console. Is there a way to do this? I just need a way to know if the page has changed. Thx

  • Mongoid Embeds_many won't save on nested form

    - by Brandon J McKay
    I've got an embeds_many association I'm trying to set up which I've done successfully before, but I'm trying to do it all in one nested form and I can't figure it out. Let's say we have a pocket model: class Pocket include Mongoid::Document field :title, type: String embeds_many :coins, cascade_callbacks: true end and a Coin Model: class Coin include Mongoid::Document field :name, type: String embedded_in :pocket end in my form for the pocket, I'm using: = f.fields_for @pocket.coins do |coin| = coin.text_field :name My controller is the default scaffolded controller. When I use the console, it saves fine and I can see the new pocket and coin I've created. But when I try to create or update a coin from the form, the pocket saves but the coin remains unchanged. What am I missing here?

    Hi! I have got model Team and I've got (i.e.) team = Team.first :offset => 20. Now I need to get number of position of my team in db table. I can do it in ruby: Team.all.index team #=> 20 But I am sure that I can write it on SQL and it will be less expensive for me with big tables.

  • Breakdown of this Ruby code?

    Would anyone be kind enough to dissect the merge! method? Its usage of conditions and variable assignment looks rather terse, and I'm having a difficult time following it.

  • CanCan polymorphic resource access problem

    - by Call 'naive' True
    Hi everybody, i don't quite understand how to restrict access to links in this particular case with CanCan. I always get "Edit" link displayed. So i believe the problem is in my incorrect definition of cancan methods(load_ and authorize_). I have CommentsController like that: class CommentsController < ApplicationController before_filter :authenticate_user! load_resource :instance_name => :commentable authorize_resource :article def index @commentable = find_commentable #loading our generic object end ...... private def find_commentable params.each { |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.includes(:comments => :karma).find(value) end } end end and i have in comments/index.html.erb following code that render file from other controller: <%= render :file => "#{get_commentable_partial_name(@commentable)}/show.html.erb", :collection => @commentable %> you can think about "#{get_commentable_partial_name(@commentable)}" like just "articles" in this case. Content of "articles/show.html.erb": <% if can? :update, @commentable %> <%= link_to 'Edit', edit_article_path(@commentable) %> | <% end %> my ability.rb: class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :author can :read, [Article, Comment, Profile] can :update, Article, :user_id => user.id end end end relations with models is: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true, :dependent => :destroy ... end class Article < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy ... end i have tried debug this issue like that user = User.first article = Article.first ability = Ability.new(user) ability.can?(:update, article) and i always get "= true" in ability check Note: user.role == author and article.user_id != user.id if you need more information please write thank's for your time && sorry for my english

  • Looking for Opinions and Sugestions on my Website. (General Question)

    - by MrEnder
    I am looking for general opinions and suggestions about the site in whole. Its ok I don't mind hearing where I went wrong on anything. I'm still learning. All tips and pointers on any subject relating are highly welcome. If you are going to make a suggestion and post a snippet or code please explain how it works in detail. The site was design as a interface to display the labs I have to do in my college (the labs are all basic things that I'm way beyond). So I decided to take it all to the next level with this. The link is http://opentech.durhamcollege.ca/~intn2201/brittains/labs/ It is 100% designed by me with the exception of the icons. (I could not think of anything better to draw) There is no specific area of the site I want suggestions or opinions on this is a general question. You may answer about the site in whole or an area of the coding just please specify. If you have any questions related to my site or code you may ask them as well. Thank you for your time and any comments Shelby

  • How to create updateable panel using AjaxLink of Wicket?

    - by Arne
    I try to realize a link (in fact many links) that update a table in an website using an AjaxLink of Wicket. But I fail, the table is never updated (I have "setOutputMarkupId(true)" and call "addComponent", but there must be something other thats wrong). How can I realize a panel with a number of links and a table that displays dynamic data, dependent on the link clicked? Can someone give an example (Maybe two links, when the first one is clicked the table displays two random numbers from 1-10, when the second is clicked the table displays random numbers from 1-100)? Without reloading the entire page, but only the html for the table?

    Can you simplify this code?. Is there anything we can do to make it more simple. I am not sure but it looks ugly to me.

  • Is there a method I can use across controllers and if so, how do I use it?

    - by Angela
    I have several controllers that take an instance of different classes each (Email, Call, Letter, etc) and they all have to go through this same substitution: @email.message.gsub!("{FirstName}", @contact.first_name) @email.message.gsub!("{Company}", @contact.company_name) @email.message.gsub!("{Colleagues}", @colleagues.to_sentence) @email.message.gsub!("{NextWeek}", (Date.today + 7.days).strftime("%A, %B %d")) @email.message.gsub!("{ContactTitle}", @contact.title ) So, for example, @call.message for Call, @letter.message for Letter, etcetera. This isn't very dry. I'd like to have something like def messagesub(asset) @asset.message.gsub.... end or something like that so I can just use messagesub method in each controller.

    I have an Activerecord object called Foo: Foo.attribute_names.each do |attribute| puts Foo.find(:all)[0].method(attribute.to_sym).call end Here I'm calling all attributes on this model (ie, querying for each column value).
