  • How to control respond_to based on variable in Rails controller?

    - by smotchkkiss
    The dilemma I'm using a before_filter in my controller that restricts access to admins. However, I want to allow access public access to some methods based on request format. See the index method to understand what I'm talking about. items_controller.rb class ItemsController < ApplicationController before_filter :superuser_required layout 'superuser' def index @items = Item.all respond_to do |format| format.html format.js # I want public to have access to this end end def show @item = Item.find(params[:id]) respond_to do |format| format.html end end def new @item = Item.new respond_to do |format| format.html end end # remaining controller methods # ... def superuser_required redirect_to login_path unless current_user.superuser? end end

  • Why doesn't this Ruby on Rails code work as I intend it to?

    - by Justin Meltzer
    So I attempted to build what I asked about in this question: Fix voting mechanism However, this solution doesn't work. A user can still vote however many times he or she wants. How could I fix this and/or refactor? def create @video = Video.find(params[:video_id]) @vote = @video.video_votes.new @vote.user = current_user if params[:type] == "up" @vote.value = 1 else @vote.value = -1 end if @previous_vote.nil? if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end elsif @previous_vote.value == params[:type] @previous_vote.destroy else @previous_vote.destroy if @vote.save respond_to do |format| format.html { redirect_to @video } format.js end else respond_to do |format| format.html { redirect_to @video } format.js {render 'fail_create.js.erb'} end end end @previous_vote = VideoVote.where(:video_id => params[:video_id], :user_id => current_user.id).first end

  • Resolving NameErrors -- Getting NameError on RAILS_END in rails_end.rb When using desert plugin and

    - by dr
    What's an effective approach to debug NameErrors in Rails? I'm trying to use the desert plugin (0.5.0) and the edge version of Community_Engine. I've started from scratch and gone through the installation instructions. When I attempt to start my server, I get this error: "Constant RAILS_END from rails_end.rb not found (NameError)". Problem is I cannot find rails_end.rb, nor can I find a google reference to this file or error. I've verified that the required gems are installed and current. I've dug around google and desert, but haven't found any reference to this constant. Any ideas? Thanks Here's my stack trace: => Booting Mongrel => Rails 2.3.2 application starting on http://0.0.0.0:3000 /opt/local/lib/ruby/gems/1.8/gems/desert-0.5.0/lib/desert/rails/ dependencies.rb:15:in `load_missing_constant': Constant RAILS_END from rails_end.rb not found (NameError) from /Users/dmr/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/ active_support/dependencies.rb:80:in `const_missing' from /Users/dmr/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/ active_support/dependencies.rb:92:in `const_missing' from /Users/dmr/dev/lionfold/config/environment.rb:32 from /Users/dmr/.gem/ruby/1.8/gems/rails-2.3.2/lib/ initializer.rb:111:in `run' from /Users/dmr/dev/myapp/config/environment.rb:31 from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/ custom_require.rb:31:in `gem_original_require' from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/ custom_require.rb:31:in `require' from /Users/dmr/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/ active_support/dependencies.rb:156:in `require' from /Users/dmr/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/ active_support/dependencies.rb:521:in `new_constants_in' from /Users/dmr/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/ active_support/dependencies.rb:156:in `require' from /Users/dmr/.gem/ruby/1.8/gems/rails-2.3.2/lib/commands/ server.rb:84 from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/ custom_require.rb:31:in `gem_original_require' from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/ custom_require.rb:31:in `require' from script/server:3

  • How do I add application specific code to Rails' plugin?

    - by Waseem
    Hi, I am using facebooker in one of my applications. I want to add some application specific methods to various methods in it? e.g. In facebooker/lib/facebooker/models/user.rb module Facebooker class User # I want to add my methods here. for e.g my_method end end I can not directly put my_method in the plugin itself since I also want to access my models from there. Not defining the methods in plugin code itself will also be helpful when I upgrade.

  • How can I install ruby on rails with rvm?

    - by yeahthatguyrightthere
    I've been searching around on how to install it through the terminal on my mac. I'm using snow leopard. When I use the command: rvm install 1.9.3 I've also followed the other procedures that led me up to this to install, right now the current version is 1.8.3 Error running './configure --prefix="/Users/jose/.rvm/usr" ', please read /Users/jose/.rvm/log/ruby-1.9.3-p125/yaml/configure.log Then it mentions something about xcode and autoreconf was not found in the PATH. Error running 'patch -F 25 -p1 -N -f <"/Users/jose/.rvm/patches/ruby/1.9.3/p125/xcode-debugopt-fix-e34840.diff"',please read /Users/jose/.rvm/log/ruby-1.9.3-p125/patch.apply.xcode-debugopt-fix-r34840.log rvm requires autoreconf to install the selected ruby interpreter however autoreconf was not found in the PATH I been trying for awhile now, and found out i need to have Xcode for snow leopard which I cannot find. So my last option will be to upgrade to lion but I don't know about upgrading. Kind of scared to upgrade and everything becomes buggy.

  • How do I display the validation which failed in my Rails unit test?

    - by JD
    Summary: Failed unit tests tell me which assert (file:line) failed, but not which validation resulted in the failure. More info: I have 11 validations in one of my models. Unit testing is great, whether I run `rake test:units --trace' or 'ruby -Itest test/unit/mymodel_test.rb'. However, despite the fact that it tells me exactly which assert() failed me, I am not told which validation failed. I must be missing something obvious, because I can't ask Google this question well enough to get an answer. Thanks :)

  • Building a rails form to filter an index page?

    - by Schroedinger
    G'day guys, I'm having an issue with filtering the presentation of several thousand trade items I have in my system. As per the specs of the system we're building we have to have a form that allows people to put in a start date and then an interval in minutes, to filter the presentation of the items. I've built my helper functions to return all of the trades within that interval period, but I can't for the life of me properly build the form that will return a dateTime value and an integer value within the top of the index page? Any ideas? Would I have to build a separate model object to assign values to, or is there a simpler way?

  • Thinking Sphinx with Rails - Delta indexing seems to work fine for one model but not for the other

    - by hack3r
    I have 2 models User and Discussion. I have defined the indices for the models as below: For the User model: define_index do indexes email indexes first_name indexes last_name, :sortable => true indexes groups(:name), :as => :group_names has "IF(email_confirmed = true and status = 'approved', true, false)", :as => :approved_user, :type => :boolean has "IF(email_confirmed = true and (status = 'approved' or status='blocked'), true, false)", :as => :approved_or_blocked_user, :type => :boolean has points, :type => :integer has created_at, :type => :datetime has user(:id) set_property :delta => true end For the Discussion model: define_index do indexes title indexes description indexes category(:title), :as => :category_title indexes tags(:title), :as => :tag_title has "IF(publish_to_blog = true AND sticky = false, true, false)", :as => :publish_to_main, :type => :boolean has created_at has updated_at, :type => :datetime has recent_activity_at, :type => :datetime has views_count, :type => :integer has featured has publish_to_blog has sticky set_property :delta => true end I have added a delta column to both tables as per the documentation. My problem is that delta indexing works only for the Discussion model and not for the User model. For ex: When I update the 'title' of a discussion, I can see the thinking sphinx is rotating the indices etc. (as is evident from the logs). But when I update the 'first_name' or the 'last_name' of a user, nothing happens. The User model also has a has_many :through association through a model called GroupsUser. I have setup a after_save on the GroupsUser as follows: def set_user_delta_flag user.delta = true user.save end Even this doesn't seem to trigger delta indexing on the User model. A similar setup for the Discussion model works perfectly! Can anyone tell me why this is happening?

  • 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!

  • What's a good plugin or guide I can use to create javascript widgets from a Rails App?

    - by nicosuria
    I've been looking around for a while now and the best guide I've seen so far is Dr Nic's DIY widgets how to (here). I haven't been able to make something like this work: Assuming this is my widget code: <script src="http://mysite/nomnoms.js"> </script> And my nomnoms controller looks like (assume that the list partial exists and simply lists down a link to the show page of each nomnom in the @nomnoms variable): class NomnomsController < ApplicationController def index @nomnoms = Nomnom.find(:all) @content = render_to_string(:partial => 'list') end end And in the index.js of my nomnoms_controller I have: page << "document.write('<div>'" page << "document.write('#{@content.to_json}')" page << "</div>" The above setup doesn't render anything :(. But when I change the second line of index.js to: page << "document.write('nomnoms should be here') ...the widget renders the text. Any help or even a point in the right direction would be greatly appreciated. Thanks in advance.

  • Java Script in Rails 3.1 works only in certain parts. Any idea why?

    - by Sergio Nekora
    This might seem a bit weird, but since I am new in RoR and cannot find any similar questions I thought you might know. The situation is that JavaScript does not work throughout my whole site. For instance. For the sake of checking, I place a link with an alert function in the footer. It did not work at the beginning, it felt like the JS was disabled(but it wasn't). But eventually it worked. Now it works in most the pages but it does not work in one that there is also an 'autocomplete' field. Of course, this autocomplete field does not work either. That could lead you to think that there is something wrong with the autocomplete code. However this same code is working in the sidebar. Any ideas why? Could it have anything to do with the fact that one day my assets folder appeared empty? After installing the gmaps4rails gem I realized that all my Js and CSS files were gone from my assests folder. Ok, it might have happened long before and I just realized at that point. I don't really know. Here in the root you can see that the 'Hola sip' click at the button works. here it works However, here same link does not trigger the alert function. here it doesn't

  • Why rails app is redirecting unexpectedly instead of matching the route?

    - by ruevaughn
    I asked this question earlier and thought it was fixed, but it's not. Previous question here My problem is I am trying to set my routes so that when I type in localhost:3000/sites/admin It should redirect to localhost:3000/en/sites/admin here is my routes.rb file scope ":locale", locale: /#{I18n.available_locales.join("|")}/ do get "log_out" => "sessions#destroy", as: "log_out" get "log_in" => "sessions#new", as: "log_in" resources :sites, except: [:new, :edit, :index, :show, :update, :destroy, :create] do collection do get :home get :about_us get :faq get :discounts get :services get :contact_us get :admin get :posts end end resources :users resources :abouts resources :sessions resources :coupons resources :monthly_posts resources :reviews resources :categories do collection { post :sort } resources :children, :controller => :categories, :only => [:index, :new, :create, :new_subcategory] end resources :products do member do put :move_up put :move_down end end resources :faqs do collection { post :sort } end root :to => 'sites#home' match "/savesort" => 'sites#savesort' end match '', to: redirect("/#{I18n.default_locale}") match '*path', to: redirect("/#{I18n.default_locale}/%{path}") But as of right now, it redirects to /en/en/en/en/en/en/en/en/en/en/sites/admin (adds en until browser complains). Any thoughts why it keeps adding /en?

  • in Rails, with check_box_tag, how do I keep the checkboxes checked after submitting query?

    - by Sebastien Paquet
    Ok, I know this is for the Saas course and people have been asking questions related to that as well but i've spent a lot of time trying and reading and I'm stuck. First of all, When you have a model called Movie, is it better to use Ratings as a model and associate them or just keep Ratings in an array floating in space(!). Second, here's what I have now in my controller: def index @movies = Movie.where(params[:ratings].present? ? {:rating => (params[:ratings].keys)} : {}).order(params[:sort]) @sort = params[:sort] @ratings = Ratings.all end Now, I decided to create a Ratings model since I thought It would be better. Here's my view: = form_tag movies_path, :method => :get do Include: - @ratings.each do |rating| = rating.rating = check_box_tag "ratings[#{rating.rating}]" = submit_tag "Refresh" I tried everything that is related to using a conditional ternary inside the checkbox tag ending with " .include?(rating) ? true : "" I tried everything that's supposed to work but it doesn't. I don't want the exact answer, I just need guidance.Thanks in advance!

  • Using routing (?) to make GET request in Rails so ID doesn't show

    - by ale
    I have a link in one view myapp/locations that goes to myapp/statistics?id=1 (statistics for location with ID 1) which works fine but it doesn't look pretty. I think I've seen people do this sort of thing without needing the ?id=1? I could use a POST but this is not RESTful. Is there a way I can use routing to allow the user to go to myapp/statistics?id=1 but have the user see myapp/statistics? Many thanks.

  • Rails - Rendering a Partial without having to use "_" in front of the filename?

    - by bluedevil2k
    How do I render a partial without having to supply the "_" in front of the file name? Is there a parameter I can call to not use it? This problem popped up using RABL and Backbone - using RABL requires me to have a file in my views like "index.json.rabl". But, when I use embed the JSON right on the page load (as is usual with Backbone), I'm required to call the file "index.json.rabl". These 2 files are the exact same thing, just required to have different names. I'm looking to use just 1 file, "index.json.rabl" and force the render() function to look for that file name, without the "".

If they have not been submitted, then there is no record of them in the approvals table. I am ending up with some really awkward code <% if !expense_item.expense_approval || expense_item.expense_approval.approval_status == 0 %> Is there a way to do an if statement on a value, without having to check if it exists first?
