  • Nokogiri pull parser (Nokogiri::XML::Reader) issue with self closing tag

    - by Vlad Zloteanu
    I have a huge XML(400MB) containing products. Using a DOM parser is therefore excluded, so i tried to parse and process it using a pull parser. Below is a snippet from the each_product(&block) method where i iterate over the product list. Basically, using a stack, i transform each <product> ... </product> node into a hash and process it. while (reader.read) case reader.node_type #start element when Nokogiri::XML::Node::ELEMENT_NODE elem_name = reader.name.to_s stack.push([elem_name, {}]) #text element when Nokogiri::XML::Node::TEXT_NODE, Nokogiri::XML::Node::CDATA_SECTION_NODE stack.last[1] = reader.value #end element when Nokogiri::XML::Node::ELEMENT_DECL return if stack.empty? elem = stack.pop parent = stack.last if parent.nil? yield(elem[1]) elem = nil next end key = elem[0] parent_childs = parent[1] # ... parent_childs[key] = elem[1] end The issue is on self-closing tags (EG <country/>), as i can not make the difference between a 'normal' and a 'self-closing' tag. They both are of type Nokogiri::XML::Node::ELEMENT_NODE and i am not able to find any other discriminator in the documentation. Any ideas on how to solve this issue?

  • devise roles: different roles, in some cases same rights

    - by mattherick
    I have two roles in devise. The first is the admin and the second the normal user-role. Now I´d like to give these two groups in some cases same rights with before filters. How does this work? I have: before_filter :authenticate_user!, :only = [:new, :create] before_filter :authenticate_admin!, :only = [:new, :create, :edit, :update, :destroy] But now only a user can :new and :create...the admin not.. What I have to do here? Thanks, Mattherick

  • "uninitialized constant Authlogic"

    - by RailAddict
    Just followed the Authlogic tutorial. I am getting "uninitialized constant Authlogic" when I try run the app. After searching, I can see that it has to do with gems/plugins but I can't find a solution. Edit: My UserSession model is: class UserSession < Authlogic::Session::Base end

  • Getting types of the attributes in an ActiveRecord object

    - by Michael Neale
    I would like to know if it is possible to get the types (as known by AR - eg in the migration script and database) programmatically (I know the data exists in there somewhere). For example, I can deal with all the attribute names: ar.attribute_names.each { |name| puts name } .attributes just returns a mapping of the names to their current values (eg no type info if the field isn't set). Some places I have seen it with the type information: in script/console, type the name of an AR entity: >> Driver => Driver(id: integer, name: string, created_at: datetime, updated_at: datetime) So clearly it knows the types. Also, there is .column_for_attribute, which takes an attr name and returns a column object - which has the type buried in the underlying database column object, but it doesn't appear to be a clean way to get it. I would also be interested in if there is a way that is friendly for the new "ActiveModel" that is coming (rails3) and is decoupled from database specifics (but perhaps type info will not be part of it, I can't seem to find out if it is). Thanks.

  • mongo mapper with STI with more than one type?

    - by holden
    I have a series of models all which inherit from a base model Properties For example Bars, Restaurants, Cafes, etc. class Property include MongoMapper::Document key :name, String key :_type, String end class Bar < Property What I'm wondering is what to do with the case when a record happens to be both a Bar & a Restaurant? Is there a way for a single object to inherit the attributes of both models? And how would it work with the key :_type?

    - by atmorell
    Hello, I am useing searchlogic to search some paintings. Each painting belong to a single category. What I would like to do is add multiple checkboxes to my search form, so that users can mark multiple categories. (joined with or) Is this possible with searchlogic? The query I am looking for is something like this: SELECT * FROM paintings WHERE category LIKE "white" OR category LIKE "red"... f.check_box :category (white) f.check_box :category (black) f.check_box :category (red) f.check_box :category (green) etc.

  • Is there a rails3-compatible emacs mode yet ?

    - by julien
    Rinari hasn't been updated in the last few months, and there doesn't seem to be such progress made in the branches on github. I've never tried emacs-rails, but from what I can see, the same applies. So, is there a rails mode somewhere that's compatible with v3 ?

  • Eager-loading association count with Arel (Rails 3)

    - by Matchu
    Simple task: given that an article has many comments, be able to display in a long list of articles how many comments each article has. I'm trying to work out how to preload this data with Arel. The "Complex Aggregations" section of the README file seems to discuss that type of situation, but it doesn't exactly offer sample code, nor does it offer a way to do it in two queries instead of one joined query, which is worse for performance. Given the following: class Article has_many :comments end class Comment belongs_to :article end How can I preload for an article set how many comments each has?

  • Add a :filter param to the end of a url

    - by bob
    Hello, I am building an application that requires a search to go deeper than the initial level. I am using nested scopes to accomplish this and params in the URL For example, when a user searches for "handbag" it creates a query like the following. http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go! I want to add a :filter param to the end of this url and reload the page with the new url. http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go!&filter=lowest_price As shown above the &filter=lowest_price is added to the query. I have already written controller code to handle this and I know it works as long as the query is like the 2nd link above. my views code <div class = "filter_options"> <p> <strong>Filter by:</strong> <%= link_to_unless_current "Recent", :filter => 'recent' %> | <%= link_to_unless_current "Lowest Price", :filter => 'lowest_price' %> | <%= link_to_unless_current "Highest Price", :filter => 'highest_price' %> </p> </div> This is how I have it currently, which works if my URL does not have a search string attached to it. Unfortunately, this will go to a http://localhost:3000/junks?filter=lowest_price even if there is a search string. I would like to know how to create my links so that they add onto the search string shown in the 2nd code example. Additionally, if a search string with a filter is already present, it would only change that filter and resubmit the search string with the new filter. I hope I am being clear.

  • How do I get autotest (ZenTest) to see my namespaced stuff?

    - by Blaine LaFreniere
    Autotest is supposed to map my tests to a class, I believe. When I have class Foo and class FooTest, autotest should see FooTest and say, "Hey, this test corresponds to the unit Foo, so I'll look for changes there and re-run tests when changes occur." And that works, however... When I have Foo::Bar and Foo::BarTest, autotest doesn't seem to make the connection, and whenever I edit Foo::Bar, autotest does not re-run Foo::BarTest Am I doing something wrong? EDIT: File structure might be helpful. Here it is: Module and class files: lib/foo.rb lib/foo/bar.rb lib/foo/baz.rb Test files: test/unit/foo/bar.rb test/unit/baz.rb I would think that autotest is able to make the connection between Foo::Bar and Foo::BarTest, but apparently it doesn't.

    I'm using rfacebook gem to interact with facebook connect. And I'm having a problem with uploading images. As facebook api says, the data should be transferred in a hash like json object. So I'm making an hash publish_values = { :uid => @post.profile.channel_uid, :message => @post.content, :auto_publish => true, } unless @post.message.skip_link_info publish_values[:attachment] = {} publish_values[:attachment][:name] = @post.message.link_title unless @post.message.link_title.blank? publish_values[:attachment][:caption] = @post.message.link_title unless @post.message.link_title.blank? publish_values[:attachment][:description] = @post.message.link_description unless @post.message.link_description.blank? unless @post.message.no_thumbnail || @post.message.link_image_url.blank? publish_values[:attachment][:media] = [{ :type => 'image', :src => @post.message.link_image_url, :href => @post.short_uri }] end end But It's not uploading any image to the facebook, the xml respons says "properties must be a dictionary".

  • Rails, gmail: howto get plain/text from body

    - by atmorell
    Hello, I am loading am email with IMAP and parsing it with mail. This works very well, however the mail.body.decoded field contains a lot of formatting.

  • Formtastic nested model form fields (Rails 3)

    - by elsurudo
    So here's the scenario: User: has_one :company accepts_nested_attributes_for :company Controller: @user = User.new @user.build_company View: <% semantic_form_for @user, :url => register_path do |form| %> <h2>User Information</h2> <%= form.inputs %> <h2>Company Information</h2> <% form.semantic_fields_for :company do |company| %> <%= company.inputs %> <% end %> <%= form.buttons %> <% end %> After scouring the web, this SEEMS like it should work. However, all I get are the user inputs. The "semantic_fields_for :company" block outputs nothing at all... Am I missing something here, or is this perhaps a Rails 3 bug to do with Formtastic?

  • How to extend an 'unloadable' Rails plugin?

    - by Vitaly Kushner
    I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

  • How does RoR's reloading content on refresh work?

    - by aharon
    RoR allows you to, as long as the env is development, change parts of the your application code and then just refresh the browser--and everything is changed, without having to restart Mongrel. How does this work, and where in the Rails codebase is this done? (Or, alternatively, is there some easy way to do this with Rack+Mongrel?) Thanks so much.

  • Rails Oauth Desktop Plugins

    - by Ryan
    I am creating a rails application that I also wish to work as a native app on the iPhone and Android. In order to facilitate this, I was thinking about becoming an OAuth provider. Is there a rails OAuth plugin that will work like this, or is there a better solution to protect the API? Note: I have found pelle's OAuth plugin, and it looks very robust, but it looks like it requires a callback URI, which the native apps would not have. Is it possible to just convert this over without much trouble?

  • When -exactly- does the Rails3 application get initialized?

    - by bergyman
    I've been fighting left and right with rails 3 and bundler. There are a few gems out there that don't work properly if the rails application hasn't been loaded yet. factory_girl and shoulda are both examples, even on the rails3 branch. Taking shoulda as an example, when trying to run rake test:units I get the following error: DEPRECATION WARNING: RAILS_ROOT is deprecated! Use Rails.root instead. (called from autoload_macros at c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/autoload_macros.rb:40) c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/autoload_macros.rb:44:in 'join': can't convert #<Class:0x232b7c0> into String (TypeError) from c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/autoload_macros.rb:44:in 'block in autoload_macros' from c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/autoload_macros.rb:44:in 'map' from c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/autoload_macros.rb:44:in 'autoload_macros' from c:/code/test_harness/vendor/windows_gems/gems/shoulda-2.10.3/lib/shoulda/rails.rb:17:in '<top (required)>' Digging a bit deeper into lib/shoulda/rails, I see this: root = if defined?(Rails.root) && Rails.root Rails.root else RAILS_ROOT end # load in the 3rd party macros from vendorized plugins and gems Shoulda.autoload_macros root, File.join("vendor", "{plugins,gems}", "*") So...what's happening here is while Rails.root is defined, Rails.root == nil, so RAILS_ROOT is used, and RAILS_ROOT==nil, which is then being passed on to Shoulda.autoload_macros. Obviously the rails app has yet to be initialized. With Rails3 using Bundler now, there's been some hubub over on the Bundler side about being able to specify an order in which the gems are required, but I'm not sure whether or not this would solve the problem at hand. Ultimately my questions is this: When exactly does the environment.rb file (which actually initializes the application) get pulled in? Is there any harm to bumping up when the app is initialized and have it happen before the Bundler.require line in config/application.rb? I've tried to hack bundler to specify the order myself, and have the rails gem pulled in first, but it doesn't appear to me that requiring the rails gem actually initializes the application. As this line (in config/application.rb) is being called before the app is initialized, any gem in the bundler Gemfile that requires rails to be initialized is going to tank. # Auto-require default libraries and those for the current Rails environment. Bundler.require :default, Rails.env

  • Get paperclip to crop the image without validating

    - by Micke
    Hello fellow stackoverflow members. I have been following this guide to enable users to have their own avatar. But i have bumped in to a litle problem. When the user is cropping the image the model tries to validate all my validations. My user model looks like this: class User < ActiveRecord::Base has_attached_file :avatar, :styles => { :small => "100x100>", :large => "500x500>" }, :processors => [:cropper] attr_accessor :password, :crop_x, :crop_y, :crop_w, :crop_h attr_accessible :crop_x, :crop_y, :crop_w, :crop_h validates_confirmation_of :password validates_presence_of :password And when the user runs the crop updating script the user model tries to validate the password. But because i have no password field on the cropping page it can't validate it. Here is the updating of the crop: @user = User.find(current_user.id) if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated user." end How can i bypass this in a easy and clean way?

  • How to validate selects / inserts are hitting the right server with MySQL Master/Slave

    - by bwizzy
    I've got a rails app using the master_slave_adapter plugin (http://github.com/mauricio/master_slave_adapter/tree/master) to send all selects to a slave, and all other statements to the master. Replication is setup using Mysql master / slave. I'm trying to validate that all the SQL statements are indeed going to the right place. Selects to the slave (db2), inserts to the master (db1) but I'm not sure how to do it. I've tried using tcpdump on the webservers: sudo /usr/sbin/tcpdump -q -i eth0 dst port 3306 and this is the output for a page request with a ton of selects: 10:32:36.570930 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 0 10:32:36.576805 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 0 10:32:36.577201 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 0 10:32:36.577980 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 86 10:32:36.578186 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 21 10:32:36.578359 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 27 10:32:36.578522 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 5 10:32:36.578741 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 13 10:32:36.579611 IP web2.mydomain.com.57524 > db1.mydomain.com.mysql: tcp 29 10:32:36.588201 IP web2.mydomain.com.45978 > db2.mydomain.com.mysql: tcp 0 10:32:36.588323 IP web2.mydomain.com.45978 > db2.mydomain.com.mysql: tcp 0 10:32:36.588677 IP web2.mydomain.com.45978 > db2.mydomain.com.mysql: tcp 0 10:32:36.588784 IP web2.mydomain.com.45978 > db2.mydomain.com.mysql: tcp 86 It doesn't look like all the selects are going to the slave.
