  • Twitter bootstrap modal loads wrong remote data

    - by Victor S
    I'm using Twitter Bootstrap modal featurs and loading data from remote locations. I'm providing the remote url for a set of thumbnails with the hope that once the thumbnail is clicked, the appropriate data (a large version of the image) is displayed. I'm using the html declarative style to define the remote urls and all the features of the modal. What I find is that Twitter bootstrap modal loads first remote url then does not display subsequent remote data, (although a request to the proper url is made in Chrome) but displays first loaded data always. How do I get it to show the proper data? View: #gallery-navigation %ul - @profile.background_images.each do |image| %li = link_to image_tag(image.background_image.url(:thumb)), remote_image_path(image.id), :role => "button", :data => {:toggle => "modal", :target => "#image-modal", :remote => remote_image_path(image.id)}, :id => "image-modal" / Modal #image-modal.modal.hide.fade(role="dialog" aria-hidden="true" data-backdrop="true") .modal-body Controller: def remote_image @image = current_user.profile.background_images.find(params[:image_id]) respond_to do |format| format.html { render :partial => "remote_image", :locals => { :image => @image } } end end

  • 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.

  • Breakdown of this Ruby code?

    - by randombits
    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. Would love to hear a Ruby-savvy developer break this apart. module ActiveRecord class Errors def merge!(errors, options={}) fields_to_merge = if only=options[:only] only elsif except=options[:except] except = [except] unless except.is_a?(Array) except.map!(&:to_sym) errors.entries.map(&:first).select do |field| !except.include?(field.to_sym) end else errors.entries.map(&:first) end fields_to_merge = [fields_to_merge] unless fields_to_merge.is_a?(Array) fields_to_merge.map!(&:to_sym) errors.entries.each do |field, msg| add field, msg if fields_to_merge.include?(field.to_sym) end end end end

  • Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

    - by James A. Rosen
    I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

  • Need to reload current_cart to get the test passed

    - by leomayleomay
    I'm testing my online store app with RSpec, here's what I'm doing: # spec/controllers/line_items_controller_spec.rb require 'spec_helper' describe LineItemsController do describe "POST 'create'" do before do @current_cart = Factory(:cart) controller.stub!(:current_cart).and_return(@current_cart) end it 'should merge two same line_items into one' do @product = Factory(:product, :name => "Tee") post 'create', {:product_id => @product.id} post 'create', {:product_id => @product.id} assert LineItem.count.should == 1 assert LineItem.first.quantity.should == 2 end end end # app/controllers/line_items_controller.rb class LineItemsController < ApplicationController def create current_cart.line_items.each do |line_item| if line_item.product_id == params[:product_id] line_item.quantity += 1 if line_item.save render :text => "success" else render :text => "failed" end return end end @line_item = current_cart.line_items.new(:product_id => params[:product_id]) if @line_item.save render :text => "success" else render :text => "failed" end end end The problem right now is it never added up two line_items having the same product into one, because the second time I entered into the line_items_controller#create, the current_cart.line_items is [], I have run current_cart.reload to get the test passed, any idea what's going wrong?

  • Ruby: Dynamically calling available methods raising undefined method (metaprogramming)

    - by user94154
    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). However, sometimes, I'll get an undefined method error. How can ActiveRecord::Base#attribute_names return an attribute name that when converted into its own method call, raises an undefined method error? Thank

  • 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

  • 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.

  • has_one update problem

    - by Kalyan M
    I have two models, User and Account. Each user may have one account. Creating an account for a user works fine. My problem is that when I try to update the account, the previous accounts user_id is nullified and a new account row is created with the user_id. I do not want this happening. I want to update the existing row with the changes to account. How do I do this? Thanks.

  • Binding KeyUp event to Input Field

    - by user306686
    I am dynamically generating textboxes in ruby using <%0.upto(4) do |i| % <%= text_field_tag('relative_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup Another set of textboxes: <%0.upto(4) do |i| % <%= text_field_tag('rating_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup I have one more textbox: ..... I want to update id="rating_factor_" textboxes as the value in either id="multiple" textbox changes or id="relative_factor_" textboxes changes. E.g. id="multiple" textbox = 5 id="relative_factor_" value= 0.0 textbox = 1 id="relative_factor_" value= 1.0 textbox = 2 id="relative_factor_" value= 2.0 textbox = 3 id="relative_factor_" value= 3.0 textbox = 4 id="relative_factor_" value= 4.0 textbox = 5 I want to show (multiple multiple and relative_factor_ and show) id="rating_factor_" value= 0.0 textbox = 5 id="rating_factor_" value= 1.0 textbox = 10 id="rating_factor_" value= 2.0 textbox = 15 id="rating_factor_" value= 3.0 textbox = 20 id="rating_factor_" value= 4.0 textbox = 25 Now if user changes, id="relative_factor_" value= 1.0 textbox as 1.5 then id="rating_factor_" value= 1.0 textbox should be updated as 7.5 To achieve above goal, I tried binding #relative_factor_ to keyup event but as id is same for all i.e.#relative_factor_, it returns value for first textbox i.e. id="relative_factor_" value= 0.0. Please guide me to crack this problem. Thanks in Advance.

  • Retrieving all objects in code upfront for performance reasons

This makes for a bigger deal, especially if your DB cannot keep everything in memory def hitDBSeperately { get X users ...code get Y users... code get Z users... code } Versus: def hitDBInSingleCall { get X+Y+Z users code for X code for Y... }

  • Paperclip - Validate File Type but not Presence

    - by Lowgain
    I am using paperclip to handle my file uploads, and in one situation I don't want the file to be mandatory. I do however want to make sure it is a specific file type when it is present. I have this: class TestModel < ActiveRecord::Base #stuff has_attached_file :sound #etc... validates_attachment_content_type :sound, :content_type => ['audio/mp3', 'application/x-mp3'] end And when I have no sound file present, it tells me it is not one of the valid content types. I've tried adding '' to the :content_type array, which also doesn't work! I also attempted creating a lambda procedure for the :if property, but I can't get it to run without some kind of error. Anything missing here?
