  • Browser freezes when try to call a JS function along with submission of a form.

    - by Waseem
    I have form in my view like following 1 <div> 2 <% form_tag facebook_user_path do %> 3 <label>Use my photo and name from facebook?</label><br /> 4 <%= check_box_tag 'use_name_and_photo', 'yes', true %> 5 <img src="<%= @user.pic %>" /><% @user.name %> 6 7 <%= submit_tag "Finish", :id => "use_name_and_photo_submit" %> 8 <% end %> 9 </div> I have attached some JS handlers using Jquery to this form. 1 var fb = { 2 extendedPermissions: function () { 3 $("#use_name_and_photo_submit").click(function (event) { 4 FB.Connect.showPermissionDialog("email,read_stream,publish_stream", function (perms) { 5 if (!perms) { 6 alert("You have to grant facebook extended permissions to further browse the application."); 7 } else { 8 $("form").submit(function () { 9 $.post($(this).attr("action"), $(this).serialize(), null, "script"); 10 }); 11 } 12 }); 13 event.preventDefault(); 14 return false; 15 }); 16 } 17 }; 18 19 $(document).ready(function () { 20 fb.extendedPermissions(); 21 }); What I want is that when the user clicks on the "Finish" button, he is prompted for the facebook permissions dialogue and when he gives the permissions, the form is submitted to FacebookUsersController. Right now when I click the "Finish" button, facebook permissions dialogue is initiated but before I am prompted for the actual permission submission window, the browser freezes. Just like I have pressed Esc during the process. In fact status bar of the browser says "Stopped". Any help is highly appreciated.

  • How do I use a custom cookie session serializer in Rack?

    - by Damien Wilson
    Hello SO. I'm currently integrating Warden into a new Rack application I'm building. I'd like to implement a recent patch to Rack that allows me to specify how sessions are serialized; specifically, I'd like to use Rack::Session::Cookie::Identity as the session processor. Unfortunately, the documentation is a little unclear as to what syntax I should use to configure Rack::Session::Cookie in my rackup file, can anyone here tell me what I'm doing wrong? config.ru require 'my_sinatra_app' app = self use Rack::Session::Cookie.new(app, Rack::Session::Cookie::Identity.new), {:key => "auth_token"} use Warden::Manager do |warden| # Must come AFTER Rack::Session warden.default_strategies :password warden.failure_app Jelli::Auth.run! end run MySinatraApp error message from thin !! Unexpected error while processing request: undefined method `new' for #<Rack::Session::Cookie:0x00000110124128> PS: I'm using bundler to manage my gem dependencies and I've likewise included rack's master branch as the desired version. Update: As suggested in the comments below, I have read the documentation; sadly the suggested syntax in the docs is not working. Update: Still no luck on my end; offering up a bounty to whoever can help me figure this out.

  • how to refactor tricky logic involving consecutive sets?

    - by keruilin
    The rule at work here is that users can be awarded badges for a streak of 10, 20, and 30. If the user has a streak over 30, such as 40 or 50, then the logic must be that it only awards a 10-streak badge for 40 and a 20-streak badge for 50, and so on. def check_win_streak(streak) badge = 10 while badge < badge::MAX_STREAK_BADGE_SIZE do # MAX_STREAK_BADGE_SIZE = 30 if streak < badge then break end if (streak % badge == 0) then award_streak_badge(badge) end badge += 10 end end

  • Can I combine atom feeds from separate resources into one?

    - by stephemurdoch
    I have two resources for which I would like to generate feeds; they are called podcasts and posts. The problem is that when I include the auto_discovery_link in my templates, I have to add one for each of the two atom feeds that I've generated. The reason why this is a problem is that there are now two feeds for users to choose from, and most people probably won't realise that they need both so will only pick one. Is there a way to combine atom feeds from different resources into one atom feed? Like application.atom or something? I'm using builder to generate the feed.

  • Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

    - by GoodGets
    So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

  • How Do I Add Value To All Previous Values In Array

    - by James
    Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.

  • DataMapper: Create new record or update existing

    - by John Topley
    Does DataMapper provide a convenient way to create a new record when none exists or update an existing one? I couldn't find anything in the API documentation. This is what I have at the moment which doesn't seem very elegant: foo = Foo.get(id) if foo.nil? foo = Foo.create(#attributes...) else foo.update(#attributes...) end foo.save

  • Using named_scope with counts of child models

    - by Joe Cairns
    Hi, I have a simple parent object having many children. I'm trying to figure out how to use a named scope for bringing back just parents with specific numbers of children. Is this possible? class Foo < ActiveRecord::Base has_many :bars named_scope :with_no_bars, ... # count of bars == 0 named_scope :with_one_bar, ... # count of bars == 1 named_scope :with_more_than_one_bar, ... # count of bars > 1 end class Bar < ActiveRecord::Base belongs_to :foo end I'm hoping to do something like Foo.with_one_bar I could write methods on the parent class for something like this, but I'd rather have the power of the named scope

    I'm using paperclip to upload a pdf. Once the file is uploaded I need to split every page into a png. This is the command I think I need to use convert -size 640x300 fileName.pdf slide.png Now if I run that command from terminal it works fine, but I need a way of getting each slides name so I can add it into a model. What's the best way to achieve this?

  • link_to for calling an action, instead of a button_to

    - by Brian Roisentul
    I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.

  • are fixtures loaded when using the sql dump to create a test database

    - by Josh Moore
    Because of some non standard table creation options I am forced to use the sql dump instead of the standard schema.rb (i.e. I have uncommented this line in the environment.rb config.active_record.schema_format = :sql). I have noticed that when I use the sql dump that my fixtures do not seem to be loaded into the database. Some data is loaded into it but, I am not sure where it is coming from. Is this normal? and if it is normal can anybody tell me where this other data is coming from?

  • Font-awesome, input type 'submit'

    - by denis.peplin
    It seems no class for input type 'submit' in font-awesome. Is it possible to use some class from font-awesome for button input? I've added icons to all buttons (which actually links with class 'btn' from twitter-bootstrap) in my applications, but can't add icons on 'input type submit'. Or, how to use this code: input#image-button{ background: #ccc url('icon.png') no-repeat top left; padding-left: 16px; height: 16px; } html: <input type="submit" id="image-button">Text</input> (which I took from HTML: How to make a submit button with text + image in it?) with font-awesome?

  • intelligent thin start with port alias for bash

    - by seaofclouds
    i would like a single alias (ts) which starts my local development server. the script should test for an open port starting at 3000 and use the first available port. additionally, some sites require a rackup file, making -R config.ru necessary. this script should check the current directory for the config.ru file and add that to the alias if present. currently, to start my local development environment, i run: alias ts="thin -R config.ru -p 3000 start" often, i need to run several servers to test different sites, so i've created additional aliases: alias ts1="thin -R config.ru -p 3001 start"

  • Using colon syntax and variables in Sass

    - by corroded
    I am still using the old colon syntax (I prefer it more than the bracket syntax) and this particular code: a.button-link +box($main-color) +border-radius(5px) :background :color $main-color :color #fff :padding 5px generates a warning like so: DEPRECATION WARNING: On line 12, character 3 of '/Users/eumir/rails_apps/dxconnect/app/ stylesheets/partials/utilities/_link-styles.sass' Setting properties with = has been deprecated and will be removed in version 3.2. Use "background: $main-color" instead. I tried that but my background color still doesn't show up. Any help on this please? Thanks!
