  • Rails 3 namespacing requires model to be defined twice?

    - by RSG
    I'm pulling my hair out trying to understand namespacing in Rails 3. I've tried following a few different tutorials, and the only way I can get my models to work is if I define my model in both the base directory and my namespace directory. If I only define the model in the namespace directory it expects it to define both Model and Namespace::Model, as below: LoadError (Expected .../app/models/plugins/chat.rb to define Chat): or LoadError (Expected .../app/models/plugins/chat.rb to define Plugins::Chat): I'm sure I'm missing something obvious, but I could really use a pointer in the right direction. Here are the relevant excerpts. /models/plugins/chat.rb class Plugins::Chat include ActiveModel::Validations include ActiveModel::Conversion extend ActiveModel::Naming ... end /controllers/plugins/chats_controller.rb class Plugins::ChatsController < Plugins::ApplicationController load_and_authorize_resource ... end /config/routes.rb namespace :plugins do resources :chats end /config/application.rb config.autoload_paths += Dir["#{config.root}/app/models/**/"]

  • How can you pass an object from the form_for helper to a method?

    - by Alex
    So let's say I have a form which is being sent somewhere strange (and by strange we mean, NOT the default route: <% form_for @form_object, :url => {:controller => 'application', :action => 'form_action_thing'} do |f| %> <%= f.text_field :email %> <%= submit_tag 'Login' %> <% end %> Now let's say that we have the method that accepts it. def form_action_thing User.find(????? :email ?????) end My questions are thus: How does can I make the object @form_object available to the receiving method (in this case, form_action_tag)? I've tried params[:form_object], and I've scoured this site and the API, which I have to post below because SO doesn't believe I'm not a spammer (I'm a new member), as well as Googled as many permutations of this idea as I could think of. Nothing. Sorry if I missed something, i'm really trying. How do I address the object, once I've made it accessible to the method? Not params[:form_object], I'm guessing.

  • How to create picture slideshows in a rails project? Flash or otherwise

    - by Janak
    In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else. I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images I imagine there must be a plugin or something to handle this?

  • Setting new class variables inside a module

    - by Sean McCleary
    I have a plugin I have been working on that adds publishing to ActiveRecord classes. I extend my classes with my publisher like so: class Note < ActiveRecord::Base # ... publishable :related_attributes => [:taggings] end My publisher is structured like: module Publisher def self.included(base) base.send(:extend, ClassMethods) @@publishing_options = [] # does not seem to be available end module ClassMethods def publishable options={} include InstanceMethods @@publishing_options = options # does not work as class_variable_set is a private method # self.class_variable_set(:@@publishing_options, options) # results in: uninitialized class variable @@publishing_options in Publisher::ClassMethods puts "@@publishing_options: #{@@publishing_options.inspect}" # ... end # ... end module InstanceMethods # results in: uninitialized class variable @@publishing_options in Publisher::InstanceMethods def related_attributes @@publishing_options[:related_attributes] end # ... end end Any ideas on how to pass options to publishable and have them available as a class variable?

  • Problem with routes in functional testing

    - by Wishmaster
    Hi, I'm making a simple test project to prepare myself for my test. I'm fairly new to nested resources, in my example I have a newsitem and each newsitem has comments. The routing looks like this: resources :comments resources :newsitems do resources :comments end I'm setting up the functional tests for comments at the moment and I ran into some problems. This will get the index of the comments of a newsitem. @newsitem is declared in the setup ofc. test "should get index" do get :index,:newsitem_id => @newsitem assert_response :success assert_not_nil assigns(:newsitem) end But the problem lays here, in the "should get new". test "should get new" do get new_newsitem_comment_path(@newsitem) assert_response :success end I'm getting the following error. ActionController::RoutingError: No route matches {:controller=>"comments", :action=>"/newsitems/1/comments/new"} But when I look into the routes table, I see this: new_newsitem_comment GET /newsitems/:newsitem_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} Can't I use the name path or what I'm doing wrong here? Thanks in advance.

Thanks!

  • How to find the most recent associations created between two objects with Rails?

    - by Kevin
    Hi, I have a user model, a movie model and this association in user.rb (I use has_many :through because there are other associations between these two models): has_many :has_seens has_many :movies_seen, :through = :has_seens, :source = :movie I'm trying to get an array of the ten most recent has_seens associations created. For now, the only solution I found is to crawl through all the users, creating an array with every user.has_seens found, then sort the array by has_seen.created_at and only keep the last 10 items… Seems like a heavy operation. Is there a better way? Kevin

  • What's causing "NoMethodError: undefined method `include?' for nil:NilClass"

    - by NudeCanalTroll
    I have a Book model in my Rails application, with various properties (aka columns in the book db table). One of these properties is "ranking". Recently, may app has started to throw NoMethodError: undefined method 'include?' for nil:NilClass for the following code: def some_method(book, another_arg) return book.ranking unless book.ranking.blank? ... end However, it's not consistent. The vast majority of the time, accessing book.ranking works -- the error is thrown maybe 2-4% of the time. If I change the code to book[:ranking] or book['ranking'] instead of book.ranking, it works 100% of the time. Any ideas?

  • Retrieving Data From formData in Rails jquery-file-upload

    - by CanCeylan
    I am trying to add additional form data by using https://github.com/blueimp/jQuery-File-Upload/wiki/How-to-submit-additional-form-data this tutorial for jQuery-File-Upload plugin in my Rails app. I'm following the instructions for Setting formData on upload start for each individual file upload. My problem is, after saving the files with their titles as explained in tutorial, I cannot show them in the final table, because I don't know how to reach the formData's values. How should I reach the data inside data.formData = inputs.serializeArray(); and post them next to each item ? Thanks.

  • Simple Sinatra Ajax Not Working

    - by proteantech
    I was trying make an AJAX call from a static file on my computer to a simple sinatra service. The ajax call was returning with an error and no details. The server logged no errors either. Another strange symptom was that the Origin in the request header was null. I turns out that you can't make cross domain ajax calls without a little extra effort. You can set the Access-Control-Allow-Origin header on your sinatra response to expose your service to external domains using a snippet like this: get '/hi' do response['Access-Control-Allow-Origin'] = '*' content_type 'text/plain' "Hello World" end There's also another header you can set to allow other HTTP Methods besides gets, Access-Control-Request-Method. You can find more information by searching around for CORS: Cross Origin Resource Sharing and the previously mentioned headers. Oh, and in case you want to do this in Rails as well you can do something like this in your controller: after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = '*' headers['Access-Control-Request-Method'] = '*' end

  • How does Facebook codes their Cropping tool?

    - by Trip
    I ask this because I am currently trying to work out my own technique, and there are huge strategic hangups for the entire site when your begin this. Of them are: Using jCrop and rMagick, it takes up a huge amount of processing ( to which I have backgrounded ). Because I have it backgrounded, I must by ajax develop a feature that auto-updates every five seconds to check when the backgrounding is done. Has anyone accomplished this with their sites? If so, what are some creative techniques you came across to keep the processing streamline, and the users happy?

  • Processing large recordsets in Rails

    - by japancheese
    Hello, I'm trying to perform a daily operation on a larger than normal dataset (2m+ records). However, Rails seems to take a very long time performing operations on such a dataset. Operations like Dataset.all.each do |data| ... end take a very long time to complete (I assume this is because it can't fit all the items into memory at once, right?). Does anyone have any strategies on how I could handle this situation? I know SQL would probably speed up the process, but I'm looking to use the Rails environment as I can do many more complicated things to the data than I can with just SQL statements.

  • How do I make all the finders on the model ignorecase?

    - by Glex
    I have a model with several attributes, among them title and artist. The case of title and artist should be ignored in all the Active Record finders. Basically, if title or artist are present in the :conditions (or dynamically i.e. find_all_by_artist), then the WHERE artist = :artist should become WHERE UPPER(artist) = UPPER(:artist) or something along these lines. Is there a way of doing it with Rails?

  • Form submission and hyperlinks using GET and POST

    - by Jon
    I have a search resource, the user can perform searches by filling out a form and submitting it, the create action is called, the Search is saved, the show action is called, and the results are displayed. This all happens with the default POST, and all works fine. The user may want to save his search in the saved_search table (i don't use the Search table for this purpose as this table stores all searches for the purpose of compiling statistics, and gets cleared on a regular basis). Once the Search is saved, it can be re-run by clicking a hyperlink, this is where i start to get problems. I see no way of getting my hyperlink to run the create action of Search, with a POST request, and the necessary data. I then decided to try to get both form submission and the hyperlink to perform a search using a GET request, i was unable to get form_for to run my Search create action using a GET request, it always seems to get routed to my index action. Can someone suggest a good restful solution to this problem please. Many thanks

  • Session management in Rails (2.3)

    - by JussiR
    Apparently, after upgrading to Rails 2.3 my session storage has stopped working. I used to have this: session :session_expires = 3.years.from_now in my application_controller.rb, but now every time i close the browser (chrome) the session expires. I read from somewhere that session_expires would have changed to expire_after, but session :expire_after = 3.years.from_now didn't do any good eihter.

  • Rails: Creating subfolders in model?

    - by keruilin
    I'm going to have a ton of subclasses, so want to organize them under a subfolder called stream. I added the following line to the environment.rb so that all classes in the subfolder would be loaded: Rails::Initializer.run do |config| ... config.load_paths += Dir["#{RAILS_ROOT}/app/models/*"].find_all { |f| File.stat(f).directory? } ... end I thought this would solve the issue in which by convention the model class is namespaced into an according module. However, when I try to call one of the classes called stream in the stream folder, I get the following error: NoMethodError: undefined method `new' for Stream:Module from (irb):28 from /usr/local/bin/irb:12:in `<main>' Here's the model for the parent and one child: class Stream end class EventStream < Stream end Any idea what the issue is?
