  • 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?

  • 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.

  • Git access on Heroku deployment and others: connection refused

    - by Toby Hede
    I have suddenly run into an issue using git. I created a new app, went to push to Heroku and now see: ssh: connect to host heroku.com port 22: Connection refused My other previously working Heroku apps no longer work, receiving the same error. Other Heroku commands work (create, info, db:push). I also see the error when accessing Git on my unfuddle accounts. I can SSH to other services, so it doesn't look like it's my machine. Any ideas?

  • Named Blueprints with factory_girl

    - by Jason Nerer
    I am using Factory Girl but like the machinist syntax. So I wonder, if there is any way creating a named blueprint for class, so that I can have something like that: User.blueprint(:no_discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader false name "foolish" salt "21746899800.223524289203464" end User.blueprint(:discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader true name "deadbeef" salt "21746899800.223524289203464" discount_rate { DiscountRate.make(:rate => 20.00) } end DiscountRate.blueprint do rate {10} not_before ... not_after ... end Is there a way making factory_girl with machinist syntax acting like that? I did not find one. Help appreciated. Thx in advance Jason

  • Authlogic_OpenID - "uninitialized constant Rack::OpenID"

    - by Micah Alcorn
    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!

  • multiple visual effects on one event

    - by ZX12R
    I have a code that looks like this. <%= link_to_remote "View results", { :update=>"uxUpdateDiv" , :url=>{:controller=>"exam", :action=>"results"} , :loading=>visual_effect(:appear, "uxcLoader", :duration=> 0.1), :before =>visual_effect(:fade, "uxUpdateDiv", :duration => 0.1), :complete => visual_effect(:appear, "uxUpdateDiv", :duration => 1.5 ), :success=>visual_effect(:fade, "uxcLoader", :duration=> 1) } %> what happens here is not good enough for me. I want to add multiple effects for one event. Like the following: :complete=>(:fade, "uxLoader", :duration=>1 AND :fade, "uxTheOtherDiv", :duration=>1) How do i achieve this.? I am using jrails

  • Validation not bubbling up to my other models.

    - by DJTripleThreat
    Ok, I have a relationship between People, Users and Employees such that All Employees are Users and all Users are People. Person is an abstract class that User is derived from and Employee is derived from that. Now... I have an EmployeesController class and the create method looks like this: def create @employee = Employee.new(params[:employee]) @employee.user = User.new(params[:user]) @employee.user.person = Person.new(params[:person]) respond_to do |format| if @employee.save flash[:notice] = 'Employee was successfully created.' format.html { redirect_to(@employee) } format.xml { render :xml => @employee, :status => :created, :location => @employee } else format.html { render :action => "new" } format.xml { render :xml => @employee.errors, :status => :unprocessable_entity } end end end As you can see, when I'm using the :polymorphic => true clause, the way you access the super class is by doing something like @derived_class_variable.super_class_variable.super_super_etc. The Person class has a validates_presence_of :first_name and when it is satisfied, on my form, everything is OK. However, if I leave out the first name, it won't prevent the employee from being saved. What happens is that the employee record is saved but the person record isn't (because of the validation). How can I get the validation errors to show up in the flash object?

  • Partials in Liquid

    - by kostia
    Hello, We're trying to rewrite our current views from ERb to Liquid and we got following problem: we have a lot of render(:partial => '/path/to/partial') in our code, but we found absolutely no instructions how to render partials in Liquid. The only one solution we found was with help of render_to_string but it's just to ugly to be true. Thanx!

  • MongoDB architectural question

    - by pex
    I have to store 4 Models. Let's say a Post that has many and belongs to many Categories. Category on the other hand has many Qualities. At the moment I'm of the opinion, that Post and Categories are Documents. Qualities becomes an EmbeddedDocument of Categories. We're coming to the root problem: There are a lot of Votes on Qualities that belong to a Post. I thought about embed Votes in Post and give it a quality_id. I am really expecting a lot of Votes and there has to be a possibility to filter them (e.g by Username / Usergroup / Date voted). I worked with MongoMapper and I think the missing existence of find methods for EmbeddedDocuments could become a killer. On the other hand I'm wondering about performance issues. What if I want to provide a Post without all the Votes, but only a few. Or, what if I define an own Document for Votes and have tons of Vote-Documents? Wouldn't that become a performance killer?

  • SQL housekeeping tasks on Herkoku

    - by Chris Beeson
    Hi, I'm not sure how to do this... I have a database which contains a messages and categories tables. The categories table has a field which has a count of the number of messages related to it. Sometimes however I need to deactivate (active = 0) a message, at the moment this doesn't then update the category table... I will implement this is in the end but for the time I would just like to run a script perhaps daily that goes through all the categories, counts up the messages and updates the field. What the best way of doing this? Thanks in advance Chris

  • ActiveScaffold custom action_link that should respond like update

    - by doug316
    I have a custom action link which is :inline and :post. It's a quick-link to update an attribute, and that part works just fine. After the action, my intent is to respond just like it was an update, so the row is re-rendered in the index. After the record is updated in my controller action, I call respond_to_action(:create) Just like in the create method in active scaffold. It seems like the content of the javascript response is returned correctly to the client, however, the problem: The content-type of the response header is "text/html" instead of "text/javascript", unlike with an actual update. So the JS is not executed and the row doesn't update. I can't figure out what the difference could possibly be here, I've traced extensively and even have replaced the respond_to_action with: respond_to do |format| format.js do render ... end end And it still won't set the content-type like every other action in the app. Anybody have a clue here? Something in active scaffold must be overriding the content-type and I can't figure out what it might be. Surprising this isn't documented, this doesn't seem like an unusual use-case, making an action a slave to the update re-render.

  • Masks and transparency

    - by Henrik
    Hi, I'm fairly new to Shoes and ran into two problems. First I want to set a mask using a partially transparent png, like this: mask do image "images/stencilMask.png" end Is this possible somehow or can only vector shapes be used? Apart from that, I noticed a small bug(?) when trying to set a transparent color as a stroke on any kind of text, like this: title "Hello", :stroke => rgb(1.0, 0.0, 0.0, 0.5) The transparency simply isn't applied. Am I doing anything wrong, or is this actually a bug? Cheers and thanks for all answers

  • How do you use scripting language (PHP, Python, etc) to improve your productivity?

    - by Edwin
    Hi, I'm a Delphi developer on the Windows platform, recently read the PHP tutorial at W3CSchools, it looks interesting. We all know scripting languages are very good at web site development, but I also want to utilize it to improve my productivity or get some tedious tasks done quickly, maybe some quick-and-dirty string/file processing? How do you usually do with scripting languages apart from software development? And we need a responsive, decent IDE/editor in order to gain productivity when writing scripts for this purpose? Thanks for in advance!

  • Sinatra application running on Dreamhost suddenly not working

    - by jbrennan
    My Sinatra application was running fine on Dreamhost until a few days ago (I'm not sure precisely when it went bad). Now when I visit my app I get this error: can't activate rack (~> 1.1, runtime) for ["sinatra-1.1.2"], already activated rack-1.2.1 for [] I have no idea how to fix this. I've tried updating all my gems, then touching the app/tmp/restart.txt file, but still no fix. I hadn't touched any files of my app, nor my Dreamhost account. It just busted on its own (my guess is DH changed something on their server which caused the bust). When I originally deployed my app, I had to go through some hoops to get it working, and I seem to think I was using gems in a custom location, but I can't remember exactly where or how. I don't know my way around Rack/Passenger very well. Here's my config.ru: (mostly grafted from around the web, I don't fully understand it) ENV['RACK_ENV'] = 'development' if ENV['RACK_ENV'].empty? #### Make sure my own gem path is included first ENV['GEM_HOME'] = "#{ENV['HOME']}/.gems" ENV['GEM_PATH'] = "#{ENV['HOME']}/.gems:" require 'rubygems' Gem.clear_paths ## NB! key part require 'sinatra' set :env, :production disable :run require 'MY_APP_NAME.rb' run Sinatra::Application

  • Is there some advantage to filling a stack with nils and interpreting the "top" as the last non-nil value?

    - by dwilbank
    While working on a rubymonk exercise, I am asked to implement a stack with a hard size limit. It should return 'nil' if I try to push too many values, or if I try to pop an empty stack. My solution is below, followed by their solution. Mine passes every test I can give it in my IDE, while it fails rubymonk's test. But that isn't my question. Question is, why did they choose to fill the stack with nils instead of letting it shrink and grow like it does in my version? It just makes their code more complex. Here's my solution: class Stack def initialize(size) @max = size @store = Array.new end def pop empty? ? nil : @store.pop end def push(element) return nil if full? @store.push(element) end def size @store.size end def look @store.last end private def full? @store.size == @max end def empty? @store.size == 0 end end and here is the accepted answer class Stack def initialize(size) @size = size @store = Array.new(@size) @top = -1 end def pop if empty? nil else popped = @store[@top] @store[@top] = nil @top = @top.pred popped end end def push(element) if full? or element.nil? nil else @top = @top.succ @store[@top] = element self end end def size @size end def look @store[@top] end private def full? @top == (@size - 1) end def empty? @top == -1 end end

  • statemachine, conditional transitions

    - by astropanic
    I'm currently using Workflow. class Link < ActiveRecord::Base include Workflow workflow do state :new do event :process, :transitions_to => :checking #checking http_response_code & content_type end state :checking do event :process, :transitions_to => :fetching_links # fetching all links end state :fetching_links do event :process, :transitions_to => :checking #ready for next check end end end Now, I can do: l = Link.new l.process! l.process! l.process! l.process! # n times l.process! (in a loop, or cron job for example) But it can happens, some link will not respond or give me an invalid response durning the checking process. How I can conditionally switch to another state ? I mean something like this: class Link < ActiveRecord::Base include Workflow workflow do state :new do event :process, :transitions_to => :checking #checking http_response_code & content_type end state :checking do event :process, :transitions_to => :fetching_links # if all is fine event :process, :transitions_to => :failded # if something goes wrong end state :fetching_links do event :process, :transitions_to => :checking #ready for next check end end end
