  • Jquery getJSON Not Working Cross Site

    - by CJ
    I have a piece of javascript that grabs JSON data. When executed locally everything seems to work fine. However, when I try accessing it from a different site, it doesn't work. Here's the script. $(function(){ var aT = new AjaxTest(); aT.getJson(); }); var AjaxTest = function() { this.ajaxUrl = "http://mydeveloperpage.com/sandbox/ajax_json_test/client_reciever.php"; this.getJson = function(){ $.getJSON(this.ajaxUrl, function(data){ $.each(data, function(i, piece){ alert(piece); }); }); } } You can find a copy of the exact same file at "http://mydeveloperpage.com/sandbox/ajax_json_test/". Any help would be greatly appreciated. Thanks!

  • NoMethodError for time_zone_select in a form

    - by Jack
    I've set up my app exactly in line with the Railscasts Time Zone Episode 1 but when I run <%= f.time_zone_select :time_zone, ActiveSupport::TimeZone.us_zones %> I get this error NoMethodError in Users#new Showing app/views/users/new.html.erb where line #27 raised: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<= With line 27 being the aforementioned line. I am really stuck on this...

  • Using a helper method in a mailer that is defined in a controller

    - by Horace Loeb
    The helper method current_user is defined and made available as a helper in ApplicationController like this: class ApplicationController < ActionController::Base helper_method :current_user def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end My question is how I can use the current_user helper method in a mailer template (obviously it will always return nil, but I'm trying to render a partial that depends on it). Normally when I want to use helpers in a mailer, I do something like add_template_helper(SongsHelper), but since the helper is defined in a class instead of a module I'm not sure what to do

  • searchlogic and virtual attributes

    - by Ermin
    Let's say I have the following model: Person <AR def name [self.first_name,self.middle_name,self.last_name].select{|n| n.present?}.join(' ') end end How could I do a search on the virtual attribute with searchlogic, something like: Person.search.name_like 'foo' Of courese I could construct a large statement like: Person.search.first_name_like_or_last_name_like_or_... 'argh' but surely there is a more elegant way.

  • How do I set default search conditions with Searchlogic?

    - by Danger Angell
    I've got a search form on this page: http://staging-checkpointtracker.aptanacloud.com/events If you select a State from the dropdown you get zero results because you didn't select one or more Event Division (checkboxes). What I want is to default the checkboxes to "checked" when the page first loads...to display Events in all Divisions...but I want changes made by the user to be reflected when they filter. Here's the index method in my Events controller: def index @search = Event.search(params[:search]) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @events } end end Here's my search form: <% form_for @search do |f| %> <div> <%= f.label :state_is, "State" %> <%= f.select :state_is, ['AK','AL','AR','AZ','CA','CO','CT','DC','DE','FL','GA','HI','IA','ID','IL','IN','KS','KY','LA','MA','MD','ME','MI','MN','MO','MS','MT','NC','ND','NE','NH','NJ','NM','NV','NY','OH','OK','OR','PA','RI','SC','SD','TN','TX','UT','VA','VT','WA','WI','WV','WY'], :include_blank => true %> </div> <div> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Sprint", :checked => true %> Sprint (2+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Sport" %> Sport (12+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Adventure" %> Adventure (18+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Expedition" %> Expedition (48+ hours)<br/> </div> <%= f.submit "Find Events" %> <%= link_to 'Clear', '/events' %> <% end %>

  • Thinking Sphinx - sorting by a string attribute gets out of sync when changes are made

    - by Scott Brown
    I have a "restaurants" table with a "name" column. I've defined the following index: indexes "REPLACE(UPPER(restaurants.name), 'THE ', '')", :as => :restaurant_name, :sortable => true ... because I want to sort the restaurant names without respect to the prefix "The ". My problem is that whenever one of these records is updated (in any way) the new record jumps to the top of the sort order. If another record is updated, it also jumps ahead of the rest. I end up with two lists: a list of restaurants that have been updated since the last re-indexing and a list of those that haven't. Each respective list is in alphabetical order, but I don't understand why the overall list is getting segregated this way. I do have a delayed delta index set up, and I assume the issue is related to this.

  • How to update strongly typed Html.DropDownList using Jquery

    - by Remnant
    I have a webpage with two radiobuttons and a dropdownlist as follows: <div class="sectionheader">Course <div class="dropdown"><%=Html.DropDownList("CourseSelection", Model.CourseList, new { @class = "dropdown" })%> </div> <div class="radiobuttons"><label><%=Html.RadioButton("CourseType", "Advanced", false )%> Advanced </label></div> <div class="radiobuttons"><label><%=Html.RadioButton("CourseType", "Beginner", true )%> Beginner </label></div> </div> The dropdownlist is strongly typed and populated with Model.CourseList (NB - on the first page load, 'Beginner' is the default selection and the dropdown shows the beginner course options accordingly) What I want to be able to do is to update the DropDownList based on which radiobutton is selected i.e. if 'Advanced' selected then show one list of course options in dropdown, and if 'Beginner' selected then show another list of courses. The code I would like to call sits within my Controller: public JsonResult UpdateDropDown(string courseType) { IDropDownList dropdownlistRepository = new DropDownListRepository(); IEnumerable<SelectListItem> courseList = dropdownlistRepository.GetCourseList(courseType); return Json(courseList); } Edit - Updated below to show latest position Using examples provided in jQuery in Action, I now have the following jQuery code: $('.radiobuttons input:radio').click(function() { var courseType = $(this).val(); //Get selected courseType from radiobutton var dropdownList = $(".dropdown"); //Ref for dropdownlist $.getJSON("/ByCourse/UpdateDropDown", { courseType: courseType }, function(data) { $(dropdownList).loadSelect(data); }); }); The loadSelect function is taken straight from the book and is as follows: (function($) { $.fn.emptySelect = function() { return this.each(function() { if (this.tagName == 'SELECT') this.options.length = 0; }); } $.fn.loadSelect = function(optionsDataArray) { return this.emptySelect().each(function() { if (this.tagName == 'SELECT') { var selectElement = this; $.each(optionsDataArray, function(index, optionData) { var option = new Option(optionData.Text, optionData.Value); if ($.browser.msie) { selectElement.add(option); } else { selectElement.add(option, null); } }); } }); } })(jQuery); 1 day+ later I still cannot get this to work. Assuming the jQuery code is correct then I can only think that the issue is with retrieving the actual data with $getJSON. I have verified that JsonResult UpdateDropDown does actually retrieve valid data. What am I missing? Assembly reference? (NB: I have MicrosoftAjax.js and MicrosoftMvcAjax.js in my head tags of the master page Should JsonResult be ActionResult? (I have seen both used in samples on web) Do I need to register route Controller/UpdateDropDown in Global.asax? Any further guidance would be appreciated.

  • MissingSourceFile when I run "cucumber features"

    - by Jess
    I had cucumber 0.6.1 working quite fine... but I ran the gem update cucumber command, and things went smoothly. Then when I decided to run the cucumber features command, I received this error: Using the default profile... no such file to load -- cucumber/webrat/element_locator (MissingSourceFile) /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require' /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:inpolyglot_original_require' So I tried a few things... I did a gem update on webrat, that didn't work. I removed all previous versions of cucumber by doing gem uninstall cucumber then selecting past versions. Same with webrat. No luck. What am I doing wrong?

  • jQuery - Loading content into div, styles not applied?

    - by Kenny Bones
    Hi! I'm trying to get this content loader to work and I've managed to get it to get new content, once the content is loaded it isn't styled correctly. Also the character "é" becomes a questionmark. Doctype problem? As well as the h2 tag normally having Cufon applied to it is not triggering. So basically, this content loader require me to have a bunch of pages being essentially the same, except for the content I want to retreice. This way, users can use the actual URL as you'd normally exect. Only when a link is clicked on an already loaded page, it's only the content from the #content div that's realle being replaced. I can post code here, but I think it's better to just watch it happen on the testpage. It's very low on graphics btw ;) http://www.matkalenderen.no Just click the blue text link and you'll see it. Also, the red button on the second loaded content is supposed to revert the content back to previous. But it's not being triggered or something. What's happening?

  • Can nested attributes be used in combination with inheritance?

    - by FoxDemon
    I have the following classes: Project Person Person Developer Person Manager In the Project model I have added the following statements: has_and_belongs_to_many :people accepts_nested_attributes_for :people And of course the appropriate statements in the class Person. How can I add an Developer to a Project through the nested_attributes method? The following does not work: @p.people_attributes = [{:name => "Epic Beard Man", :type => "Developer"}] @p.people => [#<Person id: nil, name: "Epic Beard Man", type: nil>] As you can see the type attributes is set to nil instead of Developer.

  • Thin permissions in etc folder (Ubuntu)

    - by Apollo
    I am working on a RoR server setup that uses Thin and Nginx. It works fine, but only if I manually add the folder /etc/thin and set the permissions to 777 in order to use the command below: thin config -C /etc/thin/testapp.yml -c /var/www/testapp --servers 1 -e production If I don't set it to 777, I get this error: me@UbuntuRails:/etc$ thin config -C /etc/thin/testapp.yml -c /var/www/testapp --servers 1 -e production /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/lib/thin/controllers/controller.rb:115:in initialize': Permission denied - /etc/thin/testapp.yml (Errno::EACCES) from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/lib/thin/controllers/controller.rb:115:inopen' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/lib/thin/controllers/controller.rb:115:in config' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/lib/thin/runner.rb:187:inrun_command' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/lib/thin/runner.rb:152:in run!' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/gems/thin-1.5.0/bin/thin:6:in' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/bin/thin:19:in load' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/bin/thin:19:in' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/bin/ruby_noexec_wrapper:14:in eval' from /usr/local/rvm/gems/ruby-1.9.3-p286@rails328/bin/ruby_noexec_wrapper:14:in' I don't like to set this folder to a 777, sounds like a rubbish workaround. I run everything from an admin user account, not root. RVM runs from my admin user and gem only works in my admin as well. If I sudo that action, nothing happens because my root doesn't "know" thin. Which is the correct way to handle this? Thanks!

  • Open source gravatar-like implementations?

    - by Tauren
    I'm already using gravatar icons for the users of my web service. However, I'm finding several problems with this approach: Only a small percentage of the users take the time to set up a gravatar profile. My users are not tech-savvy, but would be likely to add a dedicated photo to my site. Users of my service are encouraged to use images that depict them in proper uniform for the industry my service relates to. They wouldn't want that same picture to be used for personal purposes throughout the internet. They would not take the time or effort to manage a separate email address and gravatar account just to have an "in-uniform" profile photo for my service. Before I implement my own profile image feature, I was wondering if there are any open-source solutions that I could leverage with similar features to gravatar. Specifically: The ability to display any size thumbnail (up to 512px would be fine) Takes care of caching different sized thumbnails Has support for something like identicons, preferably pluggable with different style algorithms (monsters, etc.), even better if I can customize these Ability to fall-back to gravatar if no photo found Does anything like this exist? I haven't found it yet if it does.

    So I followed the railscast tutorial (http://railscasts.com/episodes/170-openid-with-authlogic) and used the old version of the plugin from Ryan's git file. I can now successfuly create/register a user using OpenID (Google), but I cannot log in with this user. When I submit the OpenID that has been registered, I get "uninitialized constant Rack::OpenID". Any ideas? Thanks!

  • weird behavior with acts_as_taggable_on

    - by macek
    For some reason, tags aren't showing up on a taggable object when an tagger is specified. testing the post class Post < ActiveRecord::Base acts_as_taggable_on :tags belongs_to :user end >> p = Post.first => #<Post id: 1, ...> >> p.is_taggable? => true >> p.tag_list = "foo, bar" => "foo, bar" >> p.save => true >> p.tags => [#<Tag id: 1, name: "foo">, #<Tag id: 2, name: "bar">] testing the user class User < ActiveRecord::Base acts_as_tagger has_many :posts end >> u = User.first => #<User id: 1, ...> >> u.is_tagger? => true >> u.tag(p, :with => "hello, world", :on => :tags) => true >> u.owned_tags => [#<Tag id: 3, name: "hello">, #<Tag id: 4, name: "world">] refresh the post >> p = Post.first => #<Post id: 1 ...> >> p.tags => [#<Tag id: 2, name: "bar">, #<Tag id: 1, name: "foo">] Where's the hello and world tags? Miraculously, if I modify the database directly to set tagger_id and tagger_type to NULL, the two missing tags will show up. I suspect there's something wrong with my User model? What gives?

  • Ruby Gem Install question + answer(on windows vista Home Basic environment)

    - by Vamsi
    Recently I am having problems with installing rcov gem on my windows (vista Home Basic environment), so after googling I found one solution and that is gem install rcov -v 0.8.1.1.0 #version that installs without errors gem update rcov #update to the latest version, in my case rcov-0.8.1.2.0-x86-mswin32 But this solution didn't worked on my colleague's system (windows xp) and after that we came to know about RubyInstaller devkit for winddows But that dev kit is not working on my vista, when I tried gem install rcov in my command prompt, it game me this error, C:\Users\Vamsi>gem install rcov Building native extensions. This could take a while... ERROR: Error installing rcov: ERROR: Failed to build gem native extension.ERROR: Failed to build gem native extension.

Can some one suggest a better solution for solving this problems for all windows environments? I am aware of cygwin for windows but I am not sure that is an 100% solution either.

  • RESTful Question/Answer design?

    - by Kirschstein
    This is a toy project I'm working on at the moment. My app contains questions with multiple choice answers. The question url is in the following format, with GET & POST mapping to different actions on the questions controller. GET: url.com/questions/:category/:difficulty => 'ask' POST: url.com/questions/:category/:difficulty => 'answer' I'm wondering if it's worth redesigning this into a RESTful style. I know I'd need to introduce answers as a resource, but I'm struggling to think of a url that would look natural for answering that question. Would a redesign be worthwhile? How would you go about structuring the urls?

  • secure rest API for running user "apps" in an iframe

    - by Brian Armstrong
    I want to let users create "apps" (like Facebook apps) for my website, and I'm trying to figure out the best way to make it secure. I have a REST api i want to run the user apps in an iframe on my own site (not a safe markup language like FBML) I was first looking at oAuth but this seems overkill for my solution. The "apps" don't need to be run on external sites or in desktop apps or anything. The user would stay on my site at all times but see the user submitted "app" through the iframe. So when I call the app the first time through the iframe, I can pass it some variables so it knows which logged in user is using it on my site. It can then use this user session in it's own API calls to customize the display. If the call is passed in the clear, I don't want someone to be able to intercept the session and impersonate the user. Does anyone know a good way to do this or good write up on it? Thanks!
