  • What does it take to get the "LyricArtist" from this XML feed using Nokogiri?

    - by fail.
    First the xml: http://api.chartlyrics.com/apiv1.asmx//GetLyric?lyricId=90&lyricCheckSum=9600c891e35f602eb6e1605fb7b5229e doc = Nokogiri::XML(open("http://api.chartlyrics.com/apiv1.asmx//GetLyric?lyricId=90&lyricCheckSum=9600c891e35f602eb6e1605fb7b5229e")) Successfully will grab the document content. After this point i am unable to get inside and grab data and i am not sure why? For example, i would expect: doc.xpath("//LyricArtist") To kick back the artist but it does not. I have tried the same thing with other feeds, such as the default RSS feed that any wordpress installation provides and if i do something like: doc.xpath("//link") I get a list of all the "links". I am definitely missing something and would love your input. thank you!!

  • Rack URL Mapping

    - by Puru puru rin..
    Hi, I am trying to write two kind of Rack routes. Rack allow us to write such routes like so: app = Rack::URLMap.new('/test' => SimpleAdapter.new, '/files' => Rack::File.new('.')) In my case, I would like to handle those routes: "/" or "index" "/*" in order to match any other routes So I had trying this: app = Rack::URLMap.new('/index' => SimpleAdapter.new, '/' => Rack::File.new('./public')) This works well, but... I don't know how to add '/' path (as alternative of '/index' path). The path '/*' is not interpreted as a wildcard, according to my tests. Do you know how I could do? Thanks

  • How to override the attr_protected?

    - by KandadaBoggu
    I have STI implementation as follows: class Automobile < ActiveRecord::Base end class Car < Automobile end class Truck < Automobile end class User < ActiveRecord::Base has_many :automobiles accepts_nested_attributes_for :automobiles end I am creating a list of automobiles for a user. For each automobile, the UI sets the type field and the properties associated with the automobile.While form submission, the type field is ignored as it is a protected attribute. How do I work around this issue? Is there a declarative way to unprotect a protected attribute?

  • how to pass session variable to model in RoR?

    - by siulamvictor
    I used a global variable in my app for passing information before. But I got a problem and thanks everyone here suggested me to store those data in session with database. I tried, but I found that I can't access the session variable in Model. I googled and knew this is the Model normal behavior, RoR won't pass the session variable to Model. So how to pass the value of the session variable into Models? or is there any other method for my use case? I need a variable storing a value, which is required in all MVCs, and should be independent between different concurrent users. Thanks everyone. :)

  • form_for with json return

    - by Lowgain
    I currently have a form like this: <% form_for @stem, :html => {:multipart => true} do |f| %> <%= f.file_field :sound %> <% end %> This outputs (essentially): <form method="post" id="new_stem" class="new_stem" action="/stems"> <input type="file" size="30" name="stem[sound]" id="stem_sound"> </form> However I'm planning to use jQuery's ajaxForm plugin here and would like the new stem to be returned in JSON format. I know if the form's action was "/stems.json" this would work, but is there a parameter I can put into the form_for call to ask it to return JSON? I tried doing <% form_for @stem, :html => {:multipart => true, :action => '/stems.json'} do |f| %> but this didn't appear to work.

  • Newbie question attribute from associated table not showing up in index view

    - by Lauren
    Hi I know this is something simple I am doing wrong. I have three tables, installation, neighborhood, schools Installation: has_many :schools has_many :neighborhoods Neighborhood: has_many :installations has_many :schools Schools: belongs_to :installations belongs_to :neighborhoods I can't figure out how to show the name of the neighborhood the school is located in on the index view. I can get it to show on the show view once I have the school id. But on the index view I can't figure out what to put in the controller that will allow me to access the neighborhood name from the neighborhood_id that is in the School model. I am sure this is so easy and I am screwing up something stupid. HELP!

  • Need advice with a model - should I choose has_many through

    - by Martin Petrov
    I have something like a blog with posts and tags. I want to add email notification functionality - users can subscribe to one or more tags and receive email notifications when new posts are added. Currently I have a Tag model. There will be a Subscriber model (containing the user's email) Do you think I also need a Subscription table where Subscriber and Tag are joined? .. or I can skip it and directly link Subscriber with Tag?

  • How to pass object in :with field for a link_to_remote call

    - by mathee
    I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

  • gsub! Is modifying unspecified strings

    - by user335729
    I'm extracting some information from an XML file, and I want to perform some modifications on the data while keeping a copy of the original in a variable "origFile". This is what I have: require "rexml/document" include REXML doc = Document.new File.new(thePath) root = doc.root array = [] root.elements.each("dict/string") {|element| array << element} origFile = [] root.elements.each("dict"){|i| origFile << i} theBody = array[6][0].to_s theBody.gsub!(/\&lt;!-- more --\&gt;/, "----------Read More----------") The problem is that after I perform gsub! on theBody, origFile also has the modification. I don't understand why this would be or how to fix it. I would really appreciate your help.

  • Dynamic use of :default_url in Paperclip

    - by dgilperez
    I'm trying to configure Paperclip to provide different missing images based on the instance's category attribute. Every category of the object has its own missing image. This is my first take: EDIT to add full models: class Service < ActiveRecord::Base attr_accessible :logo, :logo_file_name, :logo_content_type, :logo_file_size, :logo_updated_at belongs_to :category, :counter_cache => true has_attached_file :logo, :path => "/:id-:style-:filename", :url => ":s3_eu_url", :default_url => "/logos/:style/#{self.category.name]}.png", :styles => { :large => "600x400>", :medium => "300x200>", :small => "100x75>", :thumb => "60x42>" } end class Category < ActiveRecord::Base attr_accessible nil has_many :services end In my view, image_tag service.logo.url(:thumb) outputs: undefined method `category' for #<Class:0x0000010a731620> Any ideas? EDIT2: A working default_url is :default_url => "/logos/:style/missing.png", SOLUTION: See my own answer below.
