• Using ActiveRecord::Base.transaction in a rake task?

  - by Brian Jordan

  I am writing a rake task which, at one point, uses a custom YAML file import method to seed the database. At one point in the import code, I have: ActiveRecord::Base.transaction do Trying to run the rake task throws: You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] The stack trace points to the aforementioned line in the code. Is there a way to instantiate ActiveRecord::Base during a rake task? Thanks!

• xvfb on a machine with a display, can an application run 'in the background?'

  - by marfarma

  I'm setting up to cron a web scraping job, using xvfb, firefox, and watir on my Mac OS X. In testing the script so far, firefox pops up visibly on the local desktop, the watir script executes, and then firefox exits (I quit firefox in my script). I'd like to set the xvfb DISPLAY such that firefox will run, but won't be seen on the local desktop, running 'in the background' so to speak. Nothing I've been able to find online discusses such a possibility - nor explains that it's not possible. Is it possible? If so, what do I need to do to make it work?

• Sinatra: How do I provide access to a login form while preventing access to the rest of my Sinatra a

  - by Brandon Toone

  I recently created a Sinatra app with a login form (no basic auth). To prevent access to the app unless the user logged in I put a before block in place before do unless request.path_info == '/login' authenticated? end end I quickly realized that this prevented me from accessing resources in the public directory like my style sheet and logo unless authenticated first as well. To get around that I changed my filter to the following: before do unless request.path_info == '/login' || request.path_info == "/stylesheets/master.css" || request.path_info == "/images/logo.png" authenticated? end end If there were lots of resources I needed to provide exceptions to this way of making them would quickly become overwhelming. What is a better way to code this so I can make exceptions for the public directory or even its specific sub-directories and files like /stylesheets, /images, /images/bg.png but not /secret or /secret/eyes-only.pdf? Or ... Is there a completely different best-practice to handle this situation of locking down everything except the stuff related to logging in (handlers, views, resources)?

• ActiveRecordStore InvalidAuthenticityToken

  - by Andy

  I have recently been using cookie store and I want to transition to active record store. However I keep getting an invalid authenticity token. After deleting my cookies, I was able to access the page just fine, but I don't want all my users to come to my page, get a huge error and then figure out that I want them to delete their cookies. So I made a function called delete cookies: after_filter :delete_cookie def delete_cookie puts "deleting cookies" cookies.to_hash.each_pair do |k, v| puts k cookies.delete(k) end end In application controller, but it doesn't seem to be working correctly. I still see my cookie after visiting any page. I feel like there really should be a better solution but I can't seem to find any so far. Any hints?

• has_one update problem

  - by Kalyan M

  I have two models, User and Account. Each user may have one account. Creating an account for a user works fine. My problem is that when I try to update the account, the previous accounts user_id is nullified and a new account row is created with the user_id. I do not want this happening. I want to update the existing row with the changes to account. How do I do this? Thanks.

• Form is creating already loaded attributes in addition to new attributes, how do I ignore the first?

  - by looloobs

  In my application you: Have an admin user that signs on and that user has a role (separate model), then I use the declarative_authorization plugin to give access to certain areas. That admin user can also register new users in the system, when they do this (using Authlogic) they fill out a nested form that includes that new users' role. So what is happening is the role of the admin user is being loaded by the declarative_authorization and then the nested form using the has_many_nested_attributes is loading that existing role as well as the new role for the new user (users can have many roles). Is there some way I can tell the new User being created to ignore the role assigned to the current_user and only create the role in the form for the new user? I have looked through a lot of different things, but it seems to get more complicated that these are nested attributes. Thanks in advance.

• Help with active record relations

  - by Christian Fazzini

  class CreateActivities < ActiveRecord::Migration def self.up create_table :activities do |t| t.references :user t.references :media t.integer :artist_id t.string :type t.timestamps end end def self.down drop_table :activities end end class Fan < Activity belongs_to :user, :counter_cache => true end class Activity < ActiveRecord::Base belongs_to :user belongs_to :media belongs_to :artist, :class_name => 'User', :foreign_key => 'artist_id' end class User < ActiveRecord::Base has_many :activities has_many :fans end I tried changing my activity model too, without any success: class Activity < ActiveRecord::Base has_many :activities, :class_name => 'User', :foreign_key => 'user_id' has_many :activities, :class_name => 'User', :foreign_key => 'artist_id' end One thing to note. Activity is an STI. Fan inherits from Activity. In console, I do: # Create a fan object. User is a fan of himself fan = Fan.new => #<Fan id: nil, user_id: nil, media_id: nil, artist_id: nil, type: "Fan", comment: nil, created_at: nil, updated_at: nil> # Assign a user object fan.user = User.first => #<User id: 1, genre_id: 1, country_id: 1, .... # Assign an artist object fan.artist_id = User.first.id => 1 # Save the fan object fan.save! => true Activity.last => #<Fan id: 13, user_id: 1, media_id: nil, artist_id: 1, type: "Fan", comment: nil, created_at: "2010-12-30 08:41:25", updated_at: "2010-12-30 08:41:25"> Activity.last.user => #<User id: 1, genre_id: 1, country_id: 1, .....

• Get absolute (base) url in sinatra.

  - by berkes

  Right now, I do a get '/' do set :base_url, "#{request.env['rack.url_scheme']}://#{request.env['HTTP_HOST']}" # ... haml :index end to be able to use options.base_url in the HAML index.haml. But I am sure there is a far better, DRY, way of doing this. Yet I cannot see, nor find it. (I am new to Sinatra :)) Somehow, outside of get, I don't have request.env available, or so it seems. So putting it in an include did not work. How do you get your base url?

• how to model a many to many relationship

  - by Maulin

  Here is the scenario, Articles have many Comments Users can write many Comments for many Articles The comments table contains both user_id article_id as foreign keys My models are set up like so class User < ActiveRecord::Base has_many :comments has_many :articles, :through => :comments class Article < ActiveRecord::Base has_many :comments has_many :users, :through => :comments class Comment < ActiveRecord::Base belongs_to :users belongs_to :articles My routes.rb has the following code map.resources :articles, :has_many => :comments map.resources :users, :has_many => :comments which produces the following routes new_article_comment edit_article_comment new_user_comment edit_user_comment etc... This is not what I want (atleast not what I think I want), since comments must always be related to users and article, how can I get a route like so new_user_article_comment edit_user_article_comment Then I could just do new_user_article_comment_path([@user, @article]) to create a new comment

• How to search in this activerecord example?

  - by Horace Ho

  Two models: Invoice :invoice_num string :date datetime . . :disclaimer_num integer (foreign key) Disclaimer :disclaimer_num integer :version integer :body text For each disclaimer there are multiple versions and will be kept in database. This is how I write the search (simplified): scope = Invoice.scoped({ :joins => [:disclaimer] }) scope = scope.scoped :conditions => ["Invoice.invoice_num = ?", "#{params[:num]}"] scope = scope.scoped :conditions => ["Disclaimer.body LIKE ?", "%#{params[:text]}%"] However, the above search will search again all versions of the disclaimer. How can I limit the search to only the last disclaimer (i.e. the version integer is the maximum). Please note: Invoice does not keep the version number. New disclaimers will be added to disclaimer table and keep old versions.

• Problem with user login validation by authlogic

  - by Andrei

  Hi, I want to use email for signing in, and to allow users to have similar names. One way to do this is to rename login/username field to something different. However, I want to do it just by setting up authlogic. I tried the following acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field true end but it still complains that the login already exists. What must be done to avoid username validation without renaming the field?

• Super inplace controls in_place_select displays incorrectly

  - by Magicked

  I'm using the super_inplace_controls plugin to allow users to edit fields on the "show" page. However, I'm running into an issue with the in_place_select function. Here is my view: <p> <b>Status:</b> <%= in_place_select :incident, :incident_status, :choices => @statuses.map { |e| [e.name, e.id] } %> </p> This is in the 'Incident' view. IncidentStatus is a separate table that has_many Incidents. In the Incident controller, I retrieve @statuses like so: @statuses = IncidentStatus.find(:all) Everything works fine for the in_place_select, except the original display. In my browser, it shows: Status: #<IncidentStatus:0x1033147d8> Which means it's not grabbing the current incident_status.name, but it's just changing the object to a string. I'm not sure how to fix this! When I click on the "IncidentStatus:0x1033147d8", everything works properly and I can select the proper fields. Thanks for any help!

• Change a finder method w/ parameters to an association

  - by Sai Emrys

  How do I turn this into a has_one association? (Possibly has_one + a named scope for size.) class User < ActiveRecord::Base has_many :assets, :foreign_key => 'creator_id' def avatar_asset size = :thumb # The LIKE is because it might be a .jpg, .png, or .gif. # More efficient methods that can handle that are OK. ;) self.assets.find :first, :conditions => ["thumbnail = '#{size}' and filename LIKE ?", self.login + "_#{size}.%"] end end EDIT: Cuing from AnalogHole on Freenode #rubyonrails, we can do this: has_many :assets, :foreign_key => 'creator_id' do def avatar size = :thumb find :first, :conditions => ["thumbnail = ? and filename LIKE ?", size.to_s, proxy_owner.login + "_#{size}.%"] end end ... which is fairly cool, and makes syntax a bit better at least. However, this still doesn't behave as well as I would like. Particularly, it doesn't allow for further nice find chaining (such that it doesn't execute this find until it's gotten all its conditions). More importantly, it doesn't allow for use in an :include. Ideally I want to do something like this: PostsController def show post = Post.get_cache(params[:id]) { Post.find(params[:id], :include => {:comments => {:users => {:avatar_asset => :thumb}} } ... end ... so that I can cache the assets together with the post. Or cache them at all, really - e.g. get_cache(user_id){User.find(user_id, :include => :avatar_assets)} would be a good first pass. This doesn't actually work (self == User), but is correct in spirit: has_many :avatar_assets, :foreign_key => 'creator_id', :class_name => 'Asset', :conditions => ["filename LIKE ?", self.login + "_%"] (Also posted on Refactor My Code.)
