  • How does Rails find models and controllers? How can I get it to load more models?

    - by David
    I'm trying to create a non-ActiveRecord model in app/models/gamestate.rb. Then inside my controller (PlayController) I should be able to do GameState.new, right? No go: NameError (uninitialized constant PlayController::GameState): app/controllers/play_controller.rb:23:in `play' (at least in the development environment) But! If I do have a model called app/models/play.rb, then it's automatically loaded and I can do Play.new. So my question is: how does Rails know which classes to load? What sort of name mangling does it do to get from play#action to PlayController to app/controllers/play_controller.rb to app/models/play.rb? It seems awfully fragile, but maybe a better understanding of how this works would help. And finally, how can I get it to load app/models/gamestate.rb?

  • Helping Rails Newbies identify version-specific information on web pages

    - by corprew
    I am trying to help some people getting started programming on rails identify which version that advice found on web pages corresponds to, and am seeking advice and/or guides on how to do it so they don't have to rely on me and/or waste time trying outdated advice. Narrative: I am helping some people get up to speed on rails development, and their stock response to running into problems is searching google for advice. They're using 2.3.5 and thinking of moving to 3. The problem they're running into is that there's a lot of advice out there specific to older rails versions (2.2 for example being popular) that isn't identified. I can usually figure out when the pages are old pretty easily, but they can't (yet.) It seems like random web page authors don't identify which version they're using when they're using the current version, and not all pages are dated. This seems to be a general problem that will get worse -- current unadorned advice is usually 2.3.5 and older unadorned advice is 2.2.x at this point, but people are moving / will be moving to version 3 over the next while and newbies will be stuck looking at a bunch of deprecated/incompatible 2.3.x advice without realizing which version it is. Any advice / pointers / telltales?

  • how to setup rails Authenticity Token to work with multiple domains?

    - by bwizzy
    I'm building an app that uses subdomains as account handles (myaccount.domain.com) and I have my sessions configured to work across the sub-domains like so: config.action_controller.session = {:domain => '.domain.com'} In addition to the subdomain a user can input a real domain name when they are creating their account. My Nginx config is setup to watch for *.com *.net etc, and this is working to serve out the pages. The problem comes when a site visitor submits a comment form on a custom domain that was input by the user. The code is throwing an "Invalid AuthenticityToken" exception. I'm 99% sure this is because the domain the user is on isn't specified as the domain in the config.action_controller.session. Thus the authenticity token isn't getting matched up because Rails can't find their session. So, the question is: Can you set config.action_controller.session to more than 1 domain, and if so can you add / remove from that value at runtime without restarting the app?

  • My jquery AJAX POST requests works without sending an Authenticity Token (Rails)

    - by dchua
    Hi all, Is there any provisions in rails that would allow all AJAX POST requests from the site to pass without an authenticity_token? I have a Jquery POST ajax call that calls a controller method, but I did not put any authenticity code in it and yet the call succeeds. My ApplicationController does have 'request_forgery_protection' and I've changed config.action_controller.consider_all_requests_local to false in my environments/development.rb I've also searched my code to ensure that I was not overloading ajaxSend to send out authenticity tokens. Is there some mechanism in play that disables the check? Now I'm not sure if my CSRF protection is working or not. I'm using Rails 2.3.5.

    Hi all, I'm just coming back to rails coding after a long hiatus. I was using rinari previously but noticed that there's a new version of emacs-rails. Is anyone using either?? Any preferences for one over the other?? What are people using for their rails projects within emacs these days??

  • better way to write this

    - by ash34
    Hi, I have to create a hash of the form h[:bill] = ["Billy", "NA", 20, "PROJ_A"] by login where 20 is the cumulative number of hours reported by the login for all task transactions returned by the query where each login has multiple reported transactions. Did I do this in a bad way or this seems alright. h = Hash.new Task.find_each(:include => [:user], :joins => :user, :conditions => ["from_date >= ? AND from_date <= ? AND category = ?", Date.today - 30, Date.today + 30, 'PROJ1']) do |t| h[t.login.intern] = [t.user.name, 'NA', h[t.login.intern].nil? ? (t.hrs_per_day * t.num_days) : h[t.login.intern][2] + (t.hrs_day * t.workdays), t.category] end Also if I have to aggregate not just by login but login and category how do I accomplish this? thanks, ash

  • Update User Info with restful_authentication plugin in Rails?

    - by benoror
    Hi people, I want to give the users the ability to change their account info with restful_authentication plugin in rails. I added this two methods to my users controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Inmediatly after that it autocatically log out form the session. Any ideas?

  • What's the easiest way to use OAuth with ActiveResource?

    - by Barry Hess
    I'm working with some old code and using ActiveResource for a very basic Twitter integration. I'd like to touch the app code as little as possible and just bring OAuth in while still using ActiveResource. Unfortunately I'm finding no easy way to do this. I did run into the oauth-active-resource gem, but it's not exactly documented and it appears to be designed for creating full-on API wrapper libraries. As you can imagine, I'd like to avoid creating a whole Twitter ActiveResource API wrapper for this one legacy change. Any success stories out there? In my instance, it might be quicker to just leave ActiveResource rather than get this working. I'm happy to be proven wrong!

  • AuthLogic perishable_token resets on every request

    - by go minimal
    In my User model I have: acts_as_authentic do |c| c.perishable_token_valid_for = 30.minutes end In my Application Controller I have the standard boilerplate code: def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end Now in my view I need to see if a user is logged in: <% if current_user %> Sign Out <% else %> Sign In <% end %> On every single request, current_user is being called, and that causes a SELECT call to be made to the database to find the user, then an UPDATE call that updates the last_request_at and perishable_token even though I set perishable_token_valid_for = 30.minutes. Does anyone have a better way to see if a user is logged in without causing a SELECT and UPDATE on every single page of my app. Does anyone know why the perishable token keeps updating even if I set it to be valid for 30 minutes???

  • acts_as_solr returns all rows in the database when using the model as search query

    - by chris Chan
    In our application we're using acts_as_solr for search. Everything seems to be running smoothly except for the fact that using the model name as the search query returns every single row in the table. For example, let's say we have a users table. We specify acts_as_solr in our model to search the fields first name, last name and handle acts_as_solr :fields = [:handle, :lname, :fname]. When you use "user" as the search term it returns every single user in the system, or every row in the database as a result. Has anyone else run into this?

  • Internationalization of static pages with Rails

    - by Gavin
    I feel like I'm missing something really simple and I keep spinning my wheels on this problem. I currently have internationalization working throughout my app. The translations work and the routes work perfectly. At least, most of the site works with the exception of the routes to my two static pages, my "About" and "FAQ" pages. Every other link throughout the app points to the proper localized route. For example if I select "french" as my language, links point to the appropriate "(/:locale)/controller(.:format)." However, despite the changes I make throughout the app my links for the "About" and "FAQ" refuse to point to "../fr/static/about" and always point to "/static/about." To make matters stranger, when I run rake routes I see: "GET (/:locale)/static/:permalink(.:format) pages#show {:locale=/en|fr/}" and when I manually type in "../fr/static/about" the page translates perfectly. My Routes file: devise_for :users scope "(:locale)", :locale => /en|fr/ do get 'static/:permalink', :controller => 'pages', :action => 'show' resources :places, only: [:index, :show, :destroy] resources :homes, only: [:index, :show] match '/:locale' => 'places#index' get '/'=>'places#index',:as=>"root" end My ApplicationController: before_filter :set_locale def set_locale I18n.locale=params[:locale]||I18n.default_locale end def default_url_options(options={}) logger.debug "default_url_options is passed options: #{options.inspect}\n" { :locale => I18n.locale } end and My Pages Controller: class PagesController < ApplicationController before_filter :validate_page PAGES = ['about_us', 'faq'] def show render params[:permalink] end def validate_page redirect_to :status => 404 unless PAGES.include?(params[:permalink]) end end I'd be very grateful for any help ... it's just been one of those days. Edit: Thanks to Terry for jogging me to include views. <div class="container-fluid nav-collapse"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"><%= t(:'navbar.about') %><b class="caret"></b></a> <ul class="dropdown-menu"> <li><%=link_to t(:'navbar.about_us'), "/static/about_us"%></li> <li><%=link_to t(:'navbar.faq'), "/static/faq"%></li> <li><%=link_to t(:'navbar.blog'), '#' %></li> </ul> </li>

  • Serving GZipped files from s3 using the Asset Pipeline

    - by kmurph79
    I have a Rails 3.2.3 app on Heroku and I'm using the asset_sync gem to serve my assets from s3, via these instructions. It works great, except s3 is not serving up the gzipped css/js files (just the uncompressed version). I've enabled gzip compression, to no avail: config.gzip_compression = true According to Using GZIP with html pages served from Amazon S3 I need to add meta-data to the s3 object for uploading. How would I do this in concert with the Asset Pipeline? Thank you for any help.

  • Rails: how do you access RESTful helpers?

    - by Ethan
    I'm trying to work through this guide to Rails routing, but I got stuck in section 3.3: Creating a RESTful route will also make available a pile of helpers within your application and then they list some helpers like photos_url, photos_path, etc. My questions: Where can I find the complete list of helpers that is "made available?" Is there a way to call the helpers in the console? I created an app, then opened up the console with script/console. I tried to call one of the helpers on the console like this: >> entries_url But got: NameError: undefined local variable or method `entries_url' for #<Object:0x349a4> from (irb):8

  • Fetch main model and translations in one query with globalize2

    - by J. Pablo Fernández
    Is there a way to fetch the model and the translations in one query when using globalize2? For example, having a model called Language which have two fields, code and name of which the second is translatable I do the following: en = Language.find_by_code("en") and it runs this query: SELECT SQL_NO_CACHE * FROM `languages` WHERE (`languages`.`code` = 'en') LIMIT 1 and when I do: en.name it runs: SELECT SQL_NO_CACHE * FROM `language_translations` WHERE (`language_translations`.language_id = 123 AND (`language_translations`.`locale` IN ('en','root'))) and if I do it again it'll re-run the query. Is there a way to fetch all the translated data in the first query? I've tried: en = Language.find_by_code("en", :joins => "JOIN language_translations ON language_translations.language_id = languages.id") but it made no difference. UPDATE: this is being discussed as an issue in globalize2: http://github.com/joshmh/globalize2/issues/#issue/33

  • Rails created_at find condition...

    - by Dustin Brewer
    I'm attempting to sum daily purchase amounts for a given user. @dates is an array of 31 dates. I need the find condition to compare a date from the array to the created_at date of the purchases. What I'm doing below compares the exact DateTime for the create_at column. I need it to look at the day itself, not the DateTime. How can I write this so created_at is in between the date from the array? <% @dates.each do |date| %> <%= current_user.purchases.sum(:amount, :conditions = ["created_at = ?", date]) % <% end %

  • Rails: Display Maintenance Page if No Database Connection Available

    - by RobB
    I'm looking for a solution that will allow my rails app to render a user-friendly maintenance page when there is no Mysql server available to connect to. Normally a Mysql::Error is thrown from the mysql connection adapter in active_record. Something like: /!\ FAILSAFE /!\ Wed May 26 11:40:14 -0700 2010 Status: 500 Internal Server Error Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' Is there a low-overhead way to catch this error and render a maintenance page instead? I'm assuming that since connections are actually made in the active_record mysql adapter the app never makes it to the controller stack before it throws the error, so you can't catch it in a controller. Any input would be greatly appreciated.

  • CSRF protection and cross site form access

    - by fl00r
    Hi. I aw working on cross site authentication (some domains have got common authentication). So I want to send authentication data (login, password) to main domain from others. How should I use protect_from_forgery and how can I check if data received from valid domain? What I am thinking now is to turn off protect_from_forgery for session controller and check domain name of received data. But maybe I can configure CSRF protection for not only one domain?

When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?
