  • Customizing Number of Page Links Rendered With will_paginate?

    - by Moe
    I'm using the will_paginate gem for my Rails project and it's working beautifully. Unfortunately, on paginated result sets with a larger number of pages, the link section is too wide. Instead of: « Previous 1 2 … 5 6 7 8 9 10 11 12 13 … 18 19 Next » I would like to show: « Previous 1 2 … 5 6 7 8 9 … 18 19 Next » How can I reduce the number of page links being rendered? I looked at the will_paginate docs on github but couldn't find a solution. Thanks! Moe

  • gmaps4rails version 2 build method

    - by BrainLikeADullPencil
    I installed gmaps4rails for my Rails app, ran the generator, and required the two files like this in my application.js file, along with underscore.js //= require underscore //= require gmaps4rails/gmaps4rails.base //= require gmaps4rails/gmaps4rails.googlemaps adding, as instructed on github https://github.com/apneadiving/Google-Maps-for-Rails, these dependencies in layout.html.erb When I tried to create the demo map from the github page with this code, I got an error that the object doesn't have a build method. Uncaught TypeError: Object # has no method 'build' handler = Gmaps.build('Google'); handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){ markers = handler.addMarkers([ { "lat": 0, "lng": 0, "picture": { "url": "https://addons.cdn.mozilla.net/img/uploads/addon_icons/13/13028-64.png", "width": 36, "height": 36 }, "infowindow": "hello!" } ]); handler.bounds.extendWith(markers); handler.fitMapToBounds(); }); Indeed, when I look inside the base file that I require in the manifest file there is no build method for that object. How does one create a map in the new version for gmaps4rails?

  • RMagic Error in rails, with AM Charts

    - by Elliot
    Hi Everyone, I'm using AMCharts and rails. AMCharts uses the Image Magic lib to export an image of the chart. In rails this is done with the gem, RMagic. In a controller this is implemented with the following controller method: def export width = params[:width].to_i height = params[:height].to_i data = {} img = Magick::Image.new(width, height) height.times do |y| row = params["r#{y}"].split(',') row.size.times do |r| pixel = row[r].to_s.split(':') pixel[0] = pixel[0].to_s.rjust(6, '0') if pixel.size == 2 pixel[1].to_i.times do (data[y] ||= []) << pixel[0] end else (data[y] ||= []) << pixel[0] end end width.times do |x| img.pixel_color(x, y, "##{data[y][x]}") end end img.format = "PNG" send_data(img.to_blob , :disposition => 'inline', :type => 'image/png', :filename => "chart.png?#{rand(99999999).to_i}") end When the controller is accessed however, I receive this error in the page: The change you wanted was rejected. Maybe you tried to change something you didn't have access to. And this error in the logs (its running on heroku btw): ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): /home/heroku_rack/lib/static_assets.rb:9:in `call' /home/heroku_rack/lib/last_access.rb:25:in `call' /home/heroku_rack/lib/date_header.rb:14:in `call' thin (1.0.1) lib/thin/connection.rb:80:in `pre_process' thin (1.0.1) lib/thin/connection.rb:78:in `catch' thin (1.0.1) lib/thin/connection.rb:78:in `pre_process' thin (1.0.1) lib/thin/connection.rb:57:in `process' thin (1.0.1) lib/thin/connection.rb:42:in `receive_data' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run_machine' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run' thin (1.0.1) lib/thin/backends/base.rb:57:in `start' thin (1.0.1) lib/thin/server.rb:150:in `start' thin (1.0.1) lib/thin/controllers/controller.rb:80:in `start' thin (1.0.1) lib/thin/runner.rb:173:in `send' thin (1.0.1) lib/thin/runner.rb:173:in `run_command' thin (1.0.1) lib/thin/runner.rb:139:in `run!' thin (1.0.1) bin/thin:6 /usr/local/bin/thin:20:in `load' /usr/local/bin/thin:20 Rendering /disk1/home/slugs/149903_609c236_eb4f/mnt/public/422.html (422 Unprocessable Entity) Anyone have any idea what's going on here?

  • In a Rails unit test, how can I get a User fixture to load its associated Profile?

    - by MikeJ
    In the documentation concerning Fixtures (http://api.rubyonrails.org/classes/Fixtures.html) they provide the following example of using label references for associations: ### in pirates.yml reginald: name: Reginald the Pirate monkey: george ### in monkeys.yml george: name: George the Monkey pirate: reginald So following their lead, I have a User model that has_one :profile, a Profile model that belongs_to :user, and tried to set up fixtures per their example: ### in users.yml reginald: id: 1 login: reginald ### in profiles.yml reginalds_profile: id: 1 name: Reginald the Pirate user: reginald (Note: since my association is one-way, the User fixture doesn't have a "profile: reginalds_profile" association--putting it in causes an error because the SQL table has no profile_id attribute.) The problem is, in my unit tests everything seems to load correctly, but users(:reginald).profile is always nil. What am I missing?

  • nginx + passenger not using rackup file

    - by Callum Jones
    I have an issue where Passenger is not detecting the config.ru file for the following nginx server server { listen 80; passenger_enabled on; server_name callumj.com cjlondon.com; access_log logs/callumj.access.log; root /webapps/callumj_com/public; } Nginx just seems to ignore it and treat it as a normal web page (as I get forbidden areas when it tries to look for index.html in public). I have verified that the rackup command and execute config.ru and it boots up sucessfully. I have another server directive much like this which is powered by Rails and it seems to be working perfectly. Am I missing something? Thanks in advance!

  • Change find method in database search so that it isn't case sensitive in Rails app

    - by Ryan
    Hello, I am learning Rails and have created a work-in-progress app that does one-word searches on a database of shortcut keys for various programs (http://keyboardcuts.heroku.com/shortcuts/home). The search method in the Shortcut model is the following: def self.search(search) search_condition = "%" + search + "%" find(:all, :conditions => ['action LIKE ? OR application LIKE ?', search_condition, search_condition]) end ...where 'action' and 'application' are columns in a SQLite table. (source: https://we.riseup.net/rails/simple-search-tutorial) For some reason, the search seems to be case sensitive (you can see this by searching 'Paste' vs. 'paste'). Can anyone help me figure out why and what I can do to make it not case sensitive? If not, can you at least point me in the right direction? Database creation: I first copied shortcuts from various website into Excel and saved it as a CSV. Then I migrated the database and filled it with the data using db:seed and a small script I wrote (I viewed the database and it looked fine). To get the SQLite database to the server, I used Taps as outline by the Heroku website (http://blog.heroku.com/archives/2009/3/18/push_and_pull_databases_to_and_from_heroku/). I am using Ubuntu. Please let me know if you need more information. Thanks in advance for you help, very much appreciated! Ryan

  • Remove/squash entries in a vertical hash

    I have a grid that represents an X, Y matrix, stored as a hash here. Some points on the X Y matrix may have values (as type string), and some may not.

Let's say [17,3] = Raphael does not have an element in front of if (let's say - no [16,3] exists) then [17,3] should become [16,3] etc. So basically all empty items will be popped off the vertical (row) structure of the hash. Are there functions I should have a look at or is there an easy squash-like method that would just remove blanks and adjust and move other items? Thanks in advance for your help.

  • Authlogic with nested attributes and polymorphic associations

    - by ferparra
    Hi all! I'm having trouble with the following code: User < AR acts_as_authentic belongs_to :owner, :polymorphic => true end Worker < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end Employer < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end I'd like to create registration forms based on user types, and to include authentication fields such as username and password. I currently do this: UserRegistrationController < AC #i.e. a new Employer def new @employer = Employer.new @employer.build_user end ... end I then include User fields with fields_for. All views render fine, but here's the catch: I cannot build a User, it tells me :password is a wrong method, so I guess the authentication logic was bypassed. What should I do? Am I doing it wrong altogether? Should I drop polymorphic associations in favor of Single Table Inheritance? Whatever I do, I have to make sure it plays nicely with Authlogic.

  • Efficient counting of an association’s association

    - by Matthew Robertson
    In my app, when a User makes a Comment in a Post, Notifications are generated that marks that comment as unread. class Notification < ActiveRecord::Base belongs_to :user belongs_to :post belongs_to :comment class User < ActiveRecord::Base has_many :notifications class Post < ActiveRecord::Base has_many :notifications I’m making an index page that lists all the posts for a user and the notification count for each post for just that user. # posts controller @posts = Post.where( :user_id => current_user.id ) .includes(:notifications) # posts view @posts.each do |post| <%= post.notifications.count %> This doesn’t work because it counts notifications for all users. What’s an efficient way to do this without running a separate query for each post?

  • Rails: radio button selection for nested forms objects

    - by satynos
    I have the following form for photo_album which uses the nested forms feature of the Rails in saving the photos while updating the photo_album. And having trouble with the selection of radio button value. I want only one of the photos be able to select as the album cover, but due to the way rails produces form element ids and names, I am able to select all of the photos as album covers. Is there any workaround? <% form_for @photo_album do |f| %> <%= f.error_messages %> <% @photo_album.photos.each do |photo| %> <% f.fields_for :photos, photo do |photo_fields| %> <p> <%= image_tag url_for_image_column(photo, "data", :thumb) %> </p> <p> <%= photo_fields.label :title %> <%= photo_fields.text_field :title %> </p> <p> <%= photo_fields.label :body %> <%= photo_fields.text_area :body %> </p> <p> <%= photo_fields.radio_button :cover, "1" %> <%= photo_fields.label :cover, 'Album Cover', :class => 'option' %> <%= photo_fields.check_box :_delete %> <%= photo_fields.label :_delete, 'Delete', :class => 'option' %> </p> <% end %> <% end %> <p> <%= f.submit @photo_album.new_record? ? 'Create' : 'Update' %> </p> <% end %> And following is the html produced by rails (which is part of the problem) for radio buttons: <p> <input type="radio" value="1" name="photo_album[photos_attributes][0][cover]" id="photo_album_photos_attributes_0_cover_1"/> <label for="photo_album_photos_attributes_0_cover" class="option">Album Cover</label> <input type="hidden" value="0" name="photo_album[photos_attributes][0][_delete]"/><input type="checkbox" value="1" name="photo_album[photos_attributes][0][_delete]" id="photo_album_photos_attributes_0__delete"/> <label for="photo_album_photos_attributes_0__delete" class="option">Delete</label> </p>

  • How do I rollback capistrano tasks upon failure?

    - by dchua
    In my Capistrano deploy.rb, I have a couple of daemons like delayed_jobs and fetcher, starting and stopping depending on where they are in the deployment process. This method would create problems if a deployment fails, because the daemons wouldn't be managed properly (ie. two processes spawned instead of one, or processes were shutdown without restarting itself until the next deployment). Is there anyway to prevent this from happening like a rollback code? How is deployment of daemons normally done over capistrano?

  • Open Source Web Frameworks : Security

    - by trappedIntoCode
    How secure are popular open source web frameworks? I am particularly interested in popular frameworks like Rails and DJango. If I am building a site which is going to do heavy e-commerce, is it Ok to use frameworks like DJango and Satchmo? Is security compromised because their open architecture ? I know being OS does not mean being down right open to hackers, Linux uses superb authentication mechanism, but web is a different game. What can be done in this regard? UPDATE: Thanks for answers guys. I understand that I will have to find a suitable hosting service for a secure e-commerce application and that additional layers of security will be needed. I understand that Django and Rails have been designed keeping security aspects in mind, the most common form attacks like XSS, Injections etc. (Django book has a ch on Security) I was expecting comments from security Gurus. If you are a security Guru, would you recommend an important site, which is likely going to be popular, to be built on DJango or Rails?
