    Does anybody know of a plug-and-play login system that supports existing logins like Google and OpenID? I am looking to implement something similar to that of Stack Overflows. Thanks!

  • Typo blogging platform with Heroku hosting: theming

    - by Jack
    Does anyone know how to workarounds Heroku's limitations on writing to the theme files for the Typo blogging platform? I'd like to take advantage of the theming capabilities right from the browser. If any theme's stylesheet is changed I get the error message "Unable to write file" in addition to the fact that any theme being changed to one that is not the default causes the page to lose all styling and is displayed in plain text. I followed this (awesome) blog entry to get it up and working.

  • Why do you have to explicitly specify scope with friendly_id?

    - by nfm
    I'm using the friendly_id gem. I also have my routes nested: # config/routes.rb map.resources :users do |user| user.resources :events end So I have URLs like /users/nfm/events/birthday-2009. In my models, I want the event title to be scoped to the username, so that both nfm and mrmagoo can have events birthday-2009 without them being slugged. # app/models/event.rb def Event < ActiveRecord::Base has_friendly_id :title, :use_slug => true, :scope => :user belongs_to :user ... end I'm also using has_friendly_id :username in my User model. However, in my controller, I'm only pulling out events pertinent to the user who is logged in (current_user): def EventsController < ApplicationController def show @event = current_user.events.find(params[:id]) end ... end This doesn't work; I get the error ActiveRecord::RecordNotFound; expected scope but got none. # This works @event = current_user.events.find(params[:id], :scope => 'nfm') # This doesn't work, even though User has_friendly_id, so current_user.to_param _should_ return "nfm" @event = current_user.events.find(params[:id], :scope => current_user) # But this does work! @event = current_user.events.find(params[:id], :scope => current_user.to_param) SO, why do I need to explicitly specify :scope if I'm restricting it to current_user.events anyway? And why does current_user.to_param need to be called explicitly? Can I override this?

  • read/write_attribure on associations

    - by artemave
    read/write_attribute is a great way to enhance default accessors generated by ActiveRecord. Like this for example: def price read_attribute(:price) or "This item is priceless and you are by the way #{User.current.login}" end The same however does not seem to be working with associations. Demonstration: class Product < ActiveRecord::Base has_and_belongs_to_many :stores end Then >> a = Product.first => #<Product id: 1, name: "awesome product", created_at: "2010-05-07 12:11:00", updated_at: "2010-05-07 12:11:00"> >> a.stores => [#<Store id: 1, name: "ikea", created_at: "2010-05-07 12:11:28", updated_at: "2010-05-07 12:11:28">] >> a.read_attribute(:stores) => nil >> So, is there some sort of read/write_association? Or, if not, is there a reason not to have one?

  • 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

  • How do I create Twitter style URL's for my app - Using existing application or app redesign - Ruby o

    - by bgadoci
    I have developed a blog application of sorts that I am trying to allow other users to take advantage of (for free and mostly for family). I wondering if the authentication I have set up will allow for such a thing. Here is the scenario. Currently the application allows for users to sign up for an account and when they do so they can create blog posts and organize those posts via tags. The application displays no data publicly (another words, you have to login to see anything). To gain access you have to create an account and even after you do, you cannot see anyone else's information as the applications filters using the current_user method and displays in the /posts/index.html.erb page. This would be great if a user only wanted to blog and share it with themselves, not really what I am looking for. My question has two parts (hopefully I won't make anyone mad by not putting these into two questions) Is it possible for a particular users data to live at www.myapplication.com/user without moving everything to the /user/show.html.erb file? Is it possible to make some of that information (living at the URL) public but still require login for create and destroy actions. Essentially, exactly like twitter. I am just curious if I can get from where I am (using the current_user methods across controllers to display in /posts/index.html.erb) to where I want to be. My fear is that I have to redesign the app such that the user data lives in the /user/show.html.erb page. Thoughts?

I wonder if there is something I can set in the vendored gem path to represent the /posts/index.html.erb code as the /user/id code and replace id with the user name.

  • Active Record two belongs_to calls or single table inheritance

    - by ethyreal
    In linking a sports event to two teams, at first this seemed to make sense: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. If I did go with single table inheritance I wouldn't want each team to belong_to an event so would this work? # app/models/event.rb class Event < ActiveRecord::Base belongs_to :home_team belongs_to :away_team end # app/models/team.rb class Team < ActiveRecord::Base has_many :teams end # app/models/home_team.rb class HomeTeam < Team end # app/models/away_team.rb class AwayTeam < Team end I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? or is one of these solutions the best choice? Thanks

  • Getting HTTP 406 when trying to test facebooker application with cucumber

    - by Waseem
    I am trying to test facebook api calls with cucumber. Here is the code. # app/controller/facebook_users_controller.rb class FacebookUsersController < ApplicationController def create fb_user = facebook_session.user user = User.new(:facebook_uid => fb_user.uid, :facebook_session_key => facebook_session.session_key respond_to do |format| if user.save format.json { render :json => { :status => 'ok' }.to_json } end end end end # features/steps/facebook_connect_step.rb Given /^I am a facebook connected user$/ do mock_session = Facebooker::MockSession.create post('/facebook_user.json') puts response.code end When I run the cucumber step for above step definition, I get a response code of 406 instead of 200. This happens in the cucumber test environment only and not in the browser(development/production).

  • Declarative authorization and the if_attribute not working...

    - by ro
    I've been having almost the same issues as Victor Martin (you can see the questions asked here). I've got declarative authorization working for just about everything that doesn't involve using conditionals. E.g. has_permission_on :users, :to => [:edit, :update, :destroy] do if_attribute :user => is { current_user } end Are there any common pitfalls with Declarative Authorization? I'm using authlogic and I'm suspicious the 'current_user' method in the application controller might be the source of the problem.

  • Remaking this loop by user?

    - by Elliot
    I'm wondering if theres a best practice for what I'm trying to accomplish... First we have the model categories, categories, has_many posts. Now lets say, users add posts. Now, I have a page, that I want to display only the current user's posts by category. Lets say we have the following categories: A, B, and C User 1, has posted in Categories A and B. In my view I have something like: <% @categories.select {|cat| cat.posts.count > 0}.each do |category| %> <%= category.name %><br/> <% category.posts.select {|post| post.user == current_user}.each do |post| %> <%= post.content %><br/> <% end %> <% end %> For the most part its almost there. The issue is, it will still show an empty category if any posts have been entered in it at all (even if the current user has not input posts into that category. So the question boils down to: How do I make the following loop only count posts in the category from the current user? <% @categories.select {|cat| cat.posts.count 0}.each do |category| % Best, Elliot

  • Quick help refactoring Ruby Class

    - by mplacona
    I've written this class that returns feed updates, but am thinking it can be further improved. It's not glitchy or anything, but as a new ruby developer, I reckon it's always good to improve :-) class FeedManager attr_accessor :feed_object, :update, :new_entries require 'feedtosis' def initialize(feed_url) @feed_object = Feedtosis::Client.new(feed_url) fetch end def fetch @feed_object.fetch end def update @updates = fetch end def updated? @updates.new_entries.count > 0 ? true : false end def new_entries @updates.new_entries end end As you can see, it's quite simple, but the things I'm seeing that aren't quite right are: Whenever I call fetch via terminal, it prints a list with the updates, when it's really supposed return an object. So as an example, in the terminal if I do something like: client = Feedtosis::Client.new('http://stackoverflow.com/feeds') result = client.fetch I then get: <Curl::Easy http://stackoverflow.com/feeds> Which is exactly what I'd expect. However, when doing the same thing with "inniting" class with: FeedManager.new("http://stackoverflow.com/feeds") I'm getting the object returning as an array with all the items on the feed. Sure I'm doing something wrong, so any help refactoring this class will he greatly appreciated. Also, I'd like to see comments about my implementation, as well as any sort of comment to make it better would be welcome. Thanks in advance

  • How do I test an image alt value using capybara?

    - by stayce
    I'm trying to define a step to test the value of alt text of an image using capybara and the css selectors. I wrote one for input values based on the readme examples: Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id| element_value = locate("input##{input_id}").value element_value.should == input_value end But I can't figure this one out...something like: Then /^I should see the alttext "([^\"]*)"$/ do | alt_text | element_value = locate("img[alt]").value Anyone know how I can locate the alt text value?

  • How to return children objects?

Here's my code: class Fruit < ActiveRecord::Base end class Apple < Fruit end class Kiwi < Fruit end Assume that I have all the STI setup correctly, and there are multiple types of Apple and Kiwi records in the table. From here... fruits = Fruit.find(:all) ...how do I return an array of just Apples from the fruits array?

  • OpenID register on login (authlogic_openid)

    - by Glex
    What is the proper way to register users automatically when they log in with openid? I am using authlogic with an authlogic-oid gem (and an older version of openid_authentication). The stuff I read online so far seems to be obsolete. Does anyone know the proper way to do it with the new gem? What I do now is: options = params[:user_session] || {} [:openid_identifier].each { |k| options[k] = params[k] if params[k] } @user_session = UserSession.new(options) @user_session.save do |result| if result flash[:notice] = "Login successful! (#{result.inspect})" redirect_back_or_default account_url else render :action => :new end end By the way, I don't see the Login Successful flash (but that is not that big of a deal).

  • Let a question always :include its author, how?

    - by Freewind
    class Question < ActiveRecord::Base belongs_to :author end class Author < ActiveRecord::Base has_many :questions end When I find some questions, I usually need to get their authors at the same time, so I use: Question.find(:all, :include=>:authors) But I don't write the ":include" part everywhere. I hope I can define the "include" somewhere only once, and when I find questions, the author will be automaticly loaded. Is there any way to do this?

  • RoR Devise: Sign in with username OR email

    - by Patrick Oscity
    Whats the best way to enable users to log in with their email address OR their username? I am using warden + devise for authentication. I think it probably won't be too hard to do it but i guess i need some advice here on where to put all the stuff that is needed. Perhaps devise devise already provides this feature? like in the config/initializers/devise.rb you would write: config.authentication_keys = [ :email, :username ] To require both username AND email for signing in. But i really want to have only one field for both username and email and require only one of them. I'll just visualize that with some ASCII art, it should look something like this in the view: Username or Email: [____________________] Password: [____________________] [Sign In]

  • converting Date object to TimeWithZone

    I need to convert a Date object into a TimeWithZone object representing the beginning of that day in a given time zone. The following approach works, but seems too convoluted as it requires me to convert the date to a string: ?> date = Date.parse("2010-02-17") => Wed, 17 Feb 2010 >> ActiveSupport::TimeZone['Eastern Time (US & Canada)'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 EST -05:00 >> ActiveSupport::TimeZone['UTC'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 UTC 00:00 Is there a better way I'm missing?
