  • Urgent Problem: Production site is breaking because of cached routes

    - by ming yeow
    Hi folks, i have an urgent problem. Essentially, my routing works on my localhost. But when i deployed this to production, the routes does not seem to work correctly. For example, given a new route "/invites" - sometimes i will get a 404, and sometimes it will work correctly. I suspect there is some caching going on somewhere, but i am not sure. Can someone help? UPDATE: when a page is not found (when it is supposed to be ok ) Processing UsersController#network (for 67.180.78.126 at 2010-06-01 09:59:31) [GET] Parameters: {"id"="new"} ActionController::RoutingError (No route matches "/comm/role_playing_games" with {}): app/controllers/application_controller.rb:383:in prev_page_label' app/controllers/application_controller.rb:238:in log_timed_info' app/controllers/users_controller.rb:155:in network' app/controllers/users_controller.rb:151:in network' app/controllers/application_controller.rb:44:in turn_on_query_caching' app/controllers/application_controller.rb:43:in turn_on_query_caching' app/controllers/application_controller.rb:42:in turn_on_query_caching' app/controllers/application_controller.rb:41:in turn_on_query_caching' app/controllers/application_controller.rb:40:in turn_on_query_caching' app/controllers/application_controller.rb:39:in turn_on_query_caching' haml (3.0.6) lib/sass/plugin/rack.rb:41:in `call' Rendering /mnt/app/releases/20100524233313/public/404.html (404 Not Found)

  • Generating link path with parameters

    - by fl00r
    Hi. I've got model with many associations. User :has_many = :posts, :videos, :images etc I've got helper method, which receives one of this association draw_chart user.videos def draw_chart(assoc) assoc.each do |a| link_to "update", [a.user, a], :method => :put, :remote => true, :confirm => 'orrly?' end end Problem here is to send extra parameters to update action. For example I want to get this url: /users/1/videos/2?status=done but I am confused how to realize this while I am using [a.user, a] instead of user_videos_path(video, :status => 'done'). But I can't use last, because it can be either videos, or images or anything else

  • Rails: three most recent records by unique belongs_to associated record

    - by Dennis Collective
    class User has_many :comments end class Comment belongs_to :user named_scope :recent, :order => 'comments.created_at DESC' named_scope :limit, lambda { |limit| {:limit => limit}} named_scope :by_unique_users end what would I put in the :by_unique_users so that I can do Comment.recent.by_unique_users.limit(3), and only get one comment per user on sqlite named_scope :by_unique_user, :group = "user_id" works, but makes it freak out on postgres, which is deployed on production PGError: ERROR: column "comments.id" must appear in the GROUP BY clause or be used in an aggregate function

  • Why it's important to specify the complete class name in your association when using namespaces

    - by Carmine Paolino
    In my Rails application there is a model that has some has_one associations (this is a fabricated example): class Person::Admin < ActiveRecord::Base has_one :person_monthly_revenue has_one :dude_monthly_niceness accepts_nested_attributes_for :person_monthly_revenue, :dude_monthly_niceness end class Person::MonthlyRevenue < ActiveRecord::Base belongs_to :person_admin end class Dude::MonthlyNiceness < ActiveRecord::Base belongs_to :person_admin end The application talks to a backend that computes some data and returns a piece of JSON like this: { "dude_monthly_niceness": { "february": 1.1153232569518972, "october": 1.1250217200558268, "march": 1.3965786869658541, "august": 1.6293418014601631, "september": 1.4062771500697835, "may": 1.7166279693955291, "january": 1.0086401628086725, "june": 1.5711510228365859, "april": 1.5614525597326563, "december": 0.99894169970474289, "july": 1.7263264324994585, "november": 0.95044938418509506 }, "person_monthly_revenue": { "february": 10.585596551505297, "october": 10.574823016656749, "march": 9.9125274764852787, "august": 9.2111604702328922, "september": 9.7905249446675153, "may": 9.1329712474607962, "january": 10.479614016604238, "june": 9.3710235926961936, "april": 9.5897372624830304, "december": 10.052587677671438, "july": 8.9508877843925561, "november": 10.925339756096172 }, } To deserialize it, I use ActiveRecord's from_json, but instead of a Person::Admin object with all the associations in place, I get this error: >> Person::Admin.new.from_json(json) NameError: uninitialized constant Person::Admin::DudeMonthlyNiceness Am I doing something wrong? Is there a better way to deserialize data? (I can modify the backend easily) UPDATE: the original title was "How to deserialize from json to ActiveRecord objects with associations?" but it ended up being my mistake in specifying associations so I changed the title.

  • How can I get Hpricot to play nice with HTML5?

    - by Adam Singer
    I am using Hpricot to parse a theme file. I have noticed, however, that if I feed a valid HTML5 document into Hpricot(), it auto-closes HTML5 tags (like <section>), and messes with the DOCTYPE. Are there any extensions to Hpricot, or perhaps a flag I need to set, that will allow HTML5 documents to be parsed correctly?

  • Validate number of nested attributes

    - by Damien MATHIEU
    Hello, I have a model with nested attributes : class Foo < ActiveRecord::Base has_many :bar accepts_nested_attributes_for :bar end It works fine. However I'd want to be sure that for every Foo, I have at least two Bar. I can't access the bar_attributes in my validations so it seems I can't validate it. Is there any clean way to do so ?

  • How to inline compressed CSS in Rails with assets pipeline

    - by haimg
    I'm trying to inline CSS into my layout. I'm currently using = Rails.application.assets.find_asset('embedded.css').body.html_safe However, the CSS returned is not compressed. I verified what .digest_path asset file exists, and is properly compressed. I can, of course, write a helper that will check if current on-disk compressed asset file exists for a given asset, and use it. However, I think find_asset actually compiles a CSS asset each time it is called -- not good in production. I hope a cleaner solution exists for this issue.

  • Database layout for an application with geocoding features using geokit

    - by vooD
    I'm developing a real estate web catalogue and want to geocode every ad using geokit gem. My question is what would be the best database layout from the performance point if i want to make search by country, city of the selected country, administrative area or nearest metro station of the selected city. Available countries, cities, administrative areas and metro sations should be defined by the administrator of catalogue and must be validated by geocoding. I came up with single table: create_table "geo_locations", :force => true do |t| t.integer "geo_location_id" #parent geo location (ex. country is parent geo location of city t.string "country", :null => false #necessary for any geo location t.string "city", #not null for city geo location and it's children t.string "administrative_area" #not null for administrative_area geo location and it's children t.string "thoroughfare_name" #not null for metro station or street name geo location and it's children t.string "premise_number" #house number t.float "lng", :null => false t.float "lat", :null => false t.float "bound_sw_lat", :null => false t.float "bound_sw_lng", :null => false t.float "bound_ne_lat", :null => false t.float "bound_ne_lng", :null => false t.integer "mappable_id" t.string "mappable_type" t.string "type" #country, city, administrative area, metro station or address end Final geo location is address it contains all neccessary information to put marker of the real estate ad on the map. But i'm still stuck on search functionality. Any help would be highly appreciated.

  • Rendering a different controller and action while keeping errors

    - by DerNalia
    I have a form in one controller(A) that renders a partial from another controller(B), and stays on A's edit page during editing / updating etc. However... When the partial form form controller B has an error, the error doesn't show up on A's edit page right now, if there is an error, I am doing (in controller B's update method) redirect_to :controller => "A", :action => "edit" and then this is built in... but I don't know what to do with it... the error needs to be sent to controller A... but.. it doesn't format.xml { render :xml => @varFromB.errors, :status => :unprocessable_entity } thanks

  • Why doesn't Rails' "errors.full_messages" replace attribute and message variables?

    - by tybro0103
    Having a strange problem with a rails model I just created. Here are my validations: validates_presence_of :from_name, :message => 'Please provide a from name.' validates_presence_of :from_email validates_presence_of :giftition_plan_id I'm having issues using errors.full_messages as well as f.error_messages in my form: g = Giftition.create g.errors.first => ["from_name", "Please provide a from name."] >> g.errors.full_messages => ["{{attribute}} {{message}}", "{{attribute}} {{message}}", "{{attribute}} {{message}}"] I'm just getting "{{attribute}} {{message}}". Any ideas? UPDATE: I've uninstalled rails 3 and all the gems that were installed with it and that made the problem go away. It's not a fix though... I would still like to have rails 3 installed.

  • Designing model/database for distance between any two locations (that may change)

    - by Yo Ludke
    We should create a web app which has a number of events each with a location (created as user-generated content, so the number of events will be increasingly large). The distance between any events should be available, for example to determine the top 5 closest events and such things. Users may change the locations of events. How should one design the database/model for this (in a scalable way)? I was thinking of doing it with a "distance table" (like so http://www.deutschland-tourist.info/images/entfernungstabelle.gif). Then every time, if a location changes, one row and one column have to be recalculated (this should be done with a delayed job, because it is not important to have the changes instantly). Possible problems in Scaling: Database to large (n² items for n events), too much calculation to be done. For example we should see if this is okay for 10.000 users. If each has created just one event, then this would be 100 million integers... Do you think this would be a good way to do it efficiently? How could one realize such a distance table with an rails model? Is it possible with a SQL databse? Would you start other approaches?

  • Incorporation of YUI 3 in rails

    - by lorefnon
    I was wondering if any effort has been made towards integration of YUI3 with rails asset pipeline. By integration, I don't just mean a couple of helpers for including the library but rather a complete integration of YUI module loader. I'll elaborate the idea in detail: Currently, developers developing modules using YUI rely on Ant tasks for concatenating the module components and wrapping them up with some associated metadata and generating target files ( and optionally minifying and running jslint). Also, when fetching the modules, the YUI loader calculates the module dependencies and generates a single file comprising of all the dependencies which havent been included already in the page. I was wondering if the whole functionality could be seamlessly integrated into the Asset pipeline of rails.

  • Rails: Ajax-enabled form without a model object

    - by Caffeine Coma
    I'm new to Rails and having a hard time figuring out how to create a form that submits over Ajax without having a corresponding model object. My use case is a simple form that collects an email address and sends it an email; there's nothing to be persisted, so no model. In cases where I do have a model, I've had success with form_for(@model, remote: true). I can't seem to find the right helper for the case where there is no model. I tried form_tag(named_path, remote: true) and that works, but does not use Ajax. Pointers to an example with an example with a proper controller, .html.erb and routes.rb would be really appreciated.
