  • Rails - strip xml import from whitespace and line break

    - by val_to_many
    Hey folks, I am stuck with something quite simple but really annoying: I have an xml file with one node, where the content includes line breaks and whitspaces. Sadly I can't change the xml. <?xml version="1.0" encoding="utf-8" ?> <ProductFeed> ACME Ltd. Fooproduct Foo Root :: Bar Category I get to the node and can read from it without trouble: url = "http://feeds.somefeed/feed.xml.gz" @source = open((url), :http_basic_authentication=>["USER", "PW"]) @gz = Zlib::GzipReader.new(@source) @result = @gz.read @doc = Nokogiri::XML(@result) @doc.xpath("/ProductFeed/Vendors/Vendor").each do |manuf| vendor = manuf.css("Name").first.text manuf.xpath("//child::Product").each do |product| product_name = product.css("Name").text foocat = product.css("Category").text puts "#{vendor} ---- #{product_name} ---- #{foocat} " end end This results in: ACME Ltd. ---- Fooproduct ---- Foo Root :: Bar Category Obviously there are line breaks and tab stops or spaces in the string returned by product.css("Category").text. Does anyone know how to strip the result from linebreaks and taps or spaces right here? Alternatively I could do that in the next step, where I do a find on 'foocat' like barcat = Category.find_by_foocat(foocat) Thanks for helping! Val

  • How do I model teams and gameplay in this scorekeeping application?

    - by Eric Hill
    I'm writing a scorekeeping application for card game that has a few possibly-interesting constraints. The application accepts user registrations for players, then lets them check-in to a particular game (modeled as Event). After the final player registers, the app should generate teams, singles or doubles, depending on the preference of the person running the game and some validations (can't do doubles if there's an odd number checked in). There are @event.teams.count rounds in the game. To sum up: An event consists of `@event.teams.count` rounds; Teams can have 1 or more players Events have n or n/2 teams (depending on whether it's singles or doubles) Users will be members of different teams at different events Currently I have a rat's nest of associations: class User < ActiveRecord::Base has_many :teams, :through => :players has_many :events, :through => :teams class Event < ActiveRecord::Base has_many :rounds has_many :teams has_many :players, :through => :teams class Player < ActiveRecord::Base belongs_to :user belongs_to :team end class Team < ActiveRecord::Base has_many :players belongs_to :event end class Round < ActiveRecord::Base belongs_to :event belongs_to :user end The sticky part is team generation. I have basically a "start game" button that should freeze the registrations and pair up teams either singly or doubly, and render to Round#new so that the first (and subsequent) matches can be scored. Currently I'm implementing this as a check on Round#new that calls Event#generate_teams and displays the view: # Event#generate_teams def generate_teams # User has_many :events, :through => :registrations # self.doubles is a boolean denoting 2 players per team registrations.in_groups_of(self.doubles ? 2 : 1, nil).each do |side| self.teams << Player.create(self,side) end end Which doesn't work. Should there maybe be a Game model that ties everything together rather than (my current method) defining the game as an abstraction via the relationships between Events, Users, and Rounds (and Teams and Players and etc.)? My head is swimming.

  • Passing single attributes to associated factories

    - by lambdabutz
    I'm looking for a way to pass fields into the factories of associated models without having to explicitly call the factory itself. For example, lets say I have some factories like so: Factory.define :person do |person| person.name "Default Bob" person.sex "M" person.house {|p| p.association(:house)} end Factory.define :house do |house| house.color "Red" house.has_ac true house.suburb {|h| h.association(:suburb)} end Factory.define :suburb do |suburb| suburb.name "Little boxes" end This is fine and all, but if I want to use factories to create someone in a specific house in a specific suburb I have do this: sub = Factory(:suburb, :name => "Blue town") house = Factory(:house, :color => "Blue", :suburb => sub) person = Factory(:person, :name => "Bill", :house => house) While this isn't bad in this small case, my actual models sometimes have 7 or 8 associations, and when I want to create an object whose associations I only care about a single attribute, the code for this starts to get really heavy. Is there somewhat I can pass attributes to nested Factories without having to recall the Factory itself?

  • How to pass form errors in session or flash? [Rails 2.3.5]

    - by yuval
    I have a create action for a form that potentially generates errors (i.e. first name is missing) and then redirects. The problem is, that when the redirect happens those form errors get lost. How could I pass those form errors in a session to be displayed back in the original form (which should still be filled out with the previous details, as in the original error_messages behavior)? Thanks!

    [Rails] Where to put this code? I have a user1 and when another registered user2 sees the profile of user1, has some buttons on it: ['add as friend', 'give me your number', 'give me your email', 'ask her out', 'view photos'].

  • What exactly is REST architecture and how is it implemented in Rails?

    - by Jagira
    This is what I think of REST architecture. For every resource, there is an unique URI. We can manipulate that object using its URI and HTTP actions [POST, GET, PUT and DELETE]. The HTTP request transfers the representation of the state of that object. In all the texts I have read, REST is explained in a weird and confusing manner. One more thing, RESTFUL implementation in rails produces different urls for different purposes. Like /teams - for 'index' method... /teams/new - for 'new' method and so on. Ain't this moving away from rest, which defines that each resource has one unique URI???

  • Display pdf file inline in Rails app

    - by Martas
    Hi, I have a pdf file attachment saved in the cloud. The file is attached using attachment_fu. All I do to display it in the view is: <%= image_tag @model.pdf_attachment.public_filename %> When I load the page with this code in the browser, it does what I want: it displays the attached pdf file. But only on Mac. On Windows, browsers will display a broken image placeholder. Chrome's Developer Tools report: "Resource interpreted as image but transferred with MIME type application/pdf." I also tried sending the file from controller: in PdfAttachmentController: def send_pdf_attachment pdf_attachment = PdfAttachment.find params[:id] send_file pdf_attachment.public_filename, :type => pdf_attachment.content_type, :file_name => pdf_attachment.filename, :disposition => 'inline' end in routes.rb: map.send_pdf_attachment '/pdf_attachments/send_pdf_attachment/:id', :controller => 'pdf_attachments', :action => 'send_pdf_attachment' and in the view: <%= send_pdf_attachment_path @model.pdf_attachment %> or <%= image_tag( send_pdf_attachment_path @model.pdf_attachment ) %> And that doesn't display the file on Mac (I didn't try on Windows), it displays the path: pdf_attachments/send_pdf_attachment/35 So, my question is: what do I do to properly display a pdf file inline? Thanks martin

  • rake db:migrate not executing new migrations

    - by Matt H
    Hi guys. I'm trying to add some columns to an existing table, so I generated a migration that did so. When I run db:migrate the new migration isn't run and the table isn't updated. I've had this problem many times before, and it's getting bloody annoying. Output from rake db:migrate $ rake db:migrate --trace (in /Users/one/app) ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate ** Invoke db:schema:dump (first_time) ** Invoke environment ** Execute db:schema:dump

  • not unique ids in a route in Rails

    - by Victor P
    In a blog in Rails I want to have paths like http://mydomain.com/posts/28383/comments#21 This is the 21st comment of the 28383th post. The 21 is not an unique id, but the pair 28383, #21 is unique. How can I do this in Rails? Do I have to change the routes? the model? I will be very thankful if you can point me in the right direction Thanks

  • ActiveRecord exceptions not rescued

    - by zoopzoop
    I have the following code block: unless User.exist?(...) begin user = User.new(...) # Set more attributes of user user.save! rescue ActiveRecord::RecordInvalid, ActiveRecord::RecordNotUnique => e # Check if that user was created in the meantime user = User.exists?(...) raise e if user.nil? end end The reason is, as you can probably guess, that multiple processes might call this method at the same time to create the user (if it doesn't already exist), so while the first one enters the block and starts initializing a new user, setting the attributes and finally calling save!, the user might already be created. In that case I want to check again if the user exists and only raise the exception if it still doesn't (= if no other process has created it in the meantime). The problem is, that regularly ActiveRecord::RecordInvalid exceptions are raised from the save! and not rescued from the rescue block. Any ideas? EDIT: Alright, this is weird. I must be missing something. I refactored the code according to Simone's tip to look like this: unless User.find_by_email(...).present? # Here we know the user does not exist yet user = User.new(...) # Set more attributes of user unless user.save # User could not be saved for some reason, maybe created by another request? raise StandardError, "Could not create user for order #{self.id}." unless User.exists?(:email => ...) end end Now I got the following exception: ActiveRecord::RecordNotUnique: Mysql::DupEntry: Duplicate entry '[email protected]' for key 'index_users_on_email': INSERT INTO `users` ... thrown in the line where it says 'unless user.save'. How can that be? Rails thinks the user can be created because the email is unique but then the Mysql unique index prevents the insert? How likely is that? And how can it be avoided?

  • acts_as_revisable 'loses' previous models created before migration

    - by cbrulak
    I have the following the standard, regular post sample app. I created some posts then decided to introduce acts_as_revisable After following the instructions at http://github.com/rich/acts_as_revisable I see that the previous posts are not appearing in the Post.all call. However, if I use the console and do Post.find_by_sql("SELECT * FROM Post WHERE ID=1") the post shows up. Any ideas? Thanks

  • Is there a way to create a step chart using the Google Charts API?

    - by Nathan
    I'd like to use the google charts API to create a step chart for my Rails application. Preferably using the annotated timeline Google has (since it has a nice wrapper plugin for rails): http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html However, there doesn't seem to be a way to create a step chart using the annotated timeline or any other chart in the Google API. I'm looking to make a plot like this: If there is no way to do this with the google API, is there an alternative graphing library that can handle such a task?

  • Multiple Rails versions for multiple projects

    - by mathee
    I'd like to use Rails 2.2.2 for one project and Rails 2.3.2 for another. Both are installed. What is rails _2.2.2_ --version supposed to do? I've read that it makes 2.2.2 the working version -- that is, the version that will be used from that point on. But when I check rails --version, I get Rails 2.3.2. So, I also want to know what rails --version tells me; is it just the latest version of Rails that I have or is it the version that will be used for rakes? I know about RVM. Is that the best way to use different versions of Rails on different projects?

  • Please explain this Rails method to me like I'm a little kid.

    - by Senthil
    I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I see he is saving the user ip, user agent and referrer, but am confused with the req=(request) line. Any help is appreciated. Thanks

  • Nginx and Passenger deploy issue

    - by merlin
    Currently I can only get the default nginx page to come up on my domain name. I am pretty sure the error is either in the /etc/hosts file or the enginx.config file. my /etc/hosts file is 127.0.0.1 localhost.localdomain localhost myip server.mydomain.com server and nginx.config is: server { listen 80; server_name server.mydomain.com; root /whatever/pulic; passenger_enabled on; rails_env production; I don't get any errors in the log. Incidentally I can run mongrel and on mydomain:3000 see the application there.

  • Can I stop the page from 'scrolling' back to the top when a user clicks on a tab (with Rails not Jav

    - by Jake
    Ive built a webpage with 'tabs' using rails. When a user clicks a tab, a new page loads. I want to format it so the tabs are always in the same place on the page as a user clicks them. This happens as long as the user has not scrolled down on the page. If a user has scrolled down, clicking on the tab will refresh the page and it is no longer scrolled down - which make clicking the tabs look bad. Is there a way to keep the spot on the page where the user has scrolled down, without using Javascript? If it must be done with Javascript, any suggestions? T

  • How to convert records including 'include' associations to JSON.

    - by 99miles
    If I do something like: result = Appointment.find( :all, :include => :staff ) logger.debug { result.inspect } then it only prints out the Appointment data, and not the associated staff data. If I do result[0].staff.inpsect then I get the staff data of course. The problem is I want to return this to AJAX as JSON, including the staff rows. How do I force it to include the staff rows, or do I have to loop through and create something manually?

  • how do I join and include the association

    - by Mark
    Hi All, How do I use both include and join in a named scope? Post is polymorphic class Post has_many :approved_comments, :class_name => 'Comment' end class Comment belongs_to :post end Comment.find(:all, :joins => :post, :conditions => ["post.approved = ? ", true], :include => :post) This does not work as joins does an inner join, and include does a left out join. The database throws an error as both joins can't be there in same query.

  • Monitor database table for external changes from within Rails application

    - by jhwist
    I'm integrating some non-rails-model tables in my Rails application. Everything works out very nicely, the way I set up the model is: class Change < ActiveRecord::Base establish_connection(ActiveRecord::Base.configurations["otherdb_#{RAILS_ENV}"]) set_table_name "change" end This way I can use the Change model for all existing records with find etc. Now I'd like to run some sort of notification, when a record is added to the table. Since the model never gets created via Change.new and Change.save using ActiveRecord::Observer is not an option. Is there any way I can get some of my Rails code to be executed, whenever a new record is added? I looked at delayed_job but can't quite get my head around, how to set that up. I imagine it evolves around a cron-job, that selects all rows that where created since the job last ran and then calls the respective Rails code for each row.

  • Rails render partial with block

    - by brad
    I'm trying to re-use an html component that i've written that provides panel styling. Something like: <div class="v-panel"> <div class="v-panel-tr"></div> <h3>Some Title</h3> <div class="v-panel-c"> .. content goes here </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> So I see that render takes a block. I figured then I could do something like this: # /shared/_panel.html.erb <div class="v-panel"> <div class="v-panel-tr"></div> <h3><%= title %></h3> <div class="v-panel-c"> <%= yield %> </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> And I want to do something like: #some html view <%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %> <p>Here is some content to be rendered inside the panel</p> <% end %> Unfortunately this doesn't work with this error: ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN old_output_buffer = output_buffer;;@output_buffer = ''; __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s) on line #1 of app/views/sessions/new.html.erb: 1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%> ... So it doesn't like the = obviously with a block, but if I remove it, then it just doesn't output anything. Does anyone know how to do what I'm trying to achieve here? I'd like to re-use this panel html in many places on my site.
