  • Sanitizing input for display in view when using simple_format

    - by Eric
    Hi, I'm trying to figure out the right way to display comments such that newlines and links are displayed. I know that usually, you should display user-inputs only when escaping html with h(). That of course won't display newlines or links, so I found the simple_format and auto_link methods. What I am now doing is: simple_format(santize(auto_link(comment.text))) Is this the right way to do this, and is it still safe from XSS attacks? Thanks! Eric

  • 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?

  • Factory Girl sequence fails under autospec

    - by John
    I have this Factory: Factory.define :email_address do |e| e.sequence(:address) { |n| "factory_#{n}@example.com" } e.validated true end When I run my specs with rake spec, it works fine. When I run autospec, it fails right away, claiming that the email address is being used twice in two different objects (there is a validation which restricts this). Why is it behaving differently under autospec? Thanks, John

  • submit remote form with prototype

    - by badnaam
    I have a remote form like this and a checkbox in it. When I select or deselect the checkbox I would like to 1 - set the value of a hidden field 2 - ajax submit this form to its designated url. I tried $('search_form').onsubmit(), but I get an error saying onsubmit is not a function. Using prototype. Whats the best way to do this? <form onsubmit="new Ajax.Request('/searches/search_set?stype=1', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this)}); return false;" method="post" id="new_search" class="new_search" action="/searches/search_set?stype=1"><div style="margin: 0pt; padding: 0pt; display: inline;"><input type="hidden" value="3TWSyMsZXI0nltz7zHAxuj1KX=" name="authenticity_token"></div> <a onclick="setSubmit(this);" href="#" class="submit-link-button fg-button ui-state-default fg-button-icon-left ui-corner-all" id="search_submit"><span class="ui-icon ui-icon-search"></span>'Search'</a> </div> <input type="checkbox" value="Energy" onclick="refreshResults(this);" name="search[conditions][article_tag][0]" id="search_conditions_article_tag_0">

  • 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.

  • Ruby - encrypted_strings

    - by Tom Andersen
    A bit of a Ruby newbie here - should be an easy question: I want to use the encrypted_strings gem to create a password encrypted string: (from http://rdoc.info/projects/pluginaweek/encrypted_strings) Question is: Everything works fine, but how come I don't need the password to decrypt the string? Say I want to store the string somewhere for a while,like the session. Is the password also stored with it? (which would seem very strange?). And no, I'm not planning on using 'secret-key' or any similar hack as a password. I am planning on dynamically generating a class variable @@password using a uuid, which I don't store other than in memory, and can change from one running of the program to the next. Symmetric: >> password = 'shhhh' => "shhhh" >> crypted_password = password.encrypt(:symmetric, :password => 'secret_key') => "qSg8vOo6QfU=\n" >> crypted_password.class => String >> crypted_password == 'shhhh' => true >> password = crypted_password.decrypt => "shhhh"

  • Error processing Spree sample images - file not recognized by identify command in paperclip geometry.rb:29

    - by purpletonic
    I'm getting an error when I run the Spree sample data. It occurs when Spree tries to load in the product data, specifically the product images. Here's the error I'm getting: * Execute db:load_file loading ruby <GEM DIR>/sample/lib/tasks/../../db/sample/spree/products.rb -- Processing image: ror_tote.jpeg rake aborted! /var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-21549-2rktq1 is not recognized by the 'identify' command. <GEM DIR>/paperclip-2.7.1/lib/paperclip/geometry.rb:31:in `from_file' <GEM DIR>/spree/core/app/models/spree/image.rb:35:in `find_dimensions' I've made sure ImageMagick is installed correctly, as previously I was having problems with it. Here's the output I'm getting when running the identify command directly. $ identify Version: ImageMagick 6.7.7-6 2012-10-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenCL ... other usage info omitted ... I also used pry with the pry-debugger and put a breakpoint in geometry.rb inside of Paperclip. Here's what that section of geometry.rb looks like: # Uses ImageMagick to determing the dimensions of a file, passed in as either a # File or path. # NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be # a Tempfile object, which would be eligible for file deletion when no longer referenced. def self.from_file file file_path = file.respond_to?(:path) ? file.path : file raise(Errors::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank? geometry = begin silence_stream(STDERR) do binding.pry Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]") end rescue Cocaine::ExitStatusError "" rescue Cocaine::CommandNotFoundError => e raise Errors::CommandNotFoundError.new("Could not run the `identify` command. Please install ImageMagick.") end parse(geometry) || raise(Errors::NotIdentifiedByImageMagickError.new("#{file_path} is not recognized by the 'identify' command.")) end At the point of my binding.pry statement, the file_path variable is set to the following: file_path => "/var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-22732-1ctl1g1" I've also double checked that this exists, by opening my finder in this directory, and opened it with preview app; and also that the program can run identify by running %x{identify} in pry, and I receive the same version Version: ImageMagick 6.7.7-6 2012-10-06 Q16 as before. Removing the additional digits (is this a timestamp?) after the file extension and running the Paperclip.run command manually in Pry gives me a different error: Cocaine::ExitStatusError: Command 'identify -format %wx%h :file' returned 1. Expected 0 I've also tried manually updating the Paperclip gem in Spree to 3.0.2 and still get the same error. So, I'm not really sure what else to try. Is there still something incorrect with my ImageMagick setup?

  • SQL Query in Ruby: Only select the changes

    - by JJ Liu
    Suppose I have a table (PriceHistory) like this, every time I change anything in the row, I will record the whole row again in the table. id | buy_price | sell_price | change_date 1 | 2 | 2 | 2012-06-22 2 | 3 | 2 | 2012-06-20 3 | 2 | 6 | 2012-06-15 4 | 5 | 5 | 2012-06-15 5 | 5 | 7 | 2012-06-15 6 | 4 | 8 | 2012-06-12 I only care about the change of BuyPrice, Is there a way to just select row 1, 2, 3, & 5? Here is the Ruby code I come up with, but it does not only select the changed rows PriceHistory.select("id, BuyPrice, change_date"). order("change_date DESC") Both Ruby and SQL answers are fine.

  • Adding STI to Existing Table...

    - by keruilin
    I want to add STI to an existing table using a custom type column. Let's call this taste_type whose corresponding model is Fruit. In the Fruit model I have: set_inheritance_column :taste_type In my migration to add STI I have: class AddSTI < ActiveRecord::Migration def self.up add_column :fruits, :taste_type, :string, :limit => 100, :null => false Fruit.reset_column_information Fruit.find_by_id(1).update_attributes({:taste_type => 'Sour'}) end def self.down remove_column :fruits, :taste_type end end When I run the migration, I get the following error: Mysql::Error: Column 'taste_type' cannot be null: ... Any idea what's going? I can get the migration to run if I comment the set_inheritance_column in the Fruit model, then uncomment it after I run the migration. Obviously, I don't want to do this, however.

  • Represent multiple Null/Generic objects in an ActiveRecord association?

    - by slothbear
    I have a Casefile model that belongs_to a Doctor. In additional to all the "real" doctors, there are several generic Doctors: "self-treated", "not specified", and "removed" (it used to have a real doctor, but no longer does). I suspect there will be even more generic values in the future. I started with special "doctors" in the database, generated from seed. The generic Doctors only need to respond to the "name" and "real_doctor?" methods. This worked with one, was strained with two, and now feels completely broken. I want to change the behavior and can't figure out how to test it, a bad sign. Creating all the generic objects for testing is also trouble, including fake values to pass validation of the required Doctor attributes. The Null Object pattern works well for one generic object. The "name" method could check casefile.doctor.nil? and return "self-treated", as demonstrated by Craig Ambrose. What pattern should I use when there are multiple generic objects with very limited state?

  • Downsides to using FakeWeb compared to writing mocks for testing

    - by ajmurmann
    I never liked writing mocks and a while ago someone here recommended to use FakeWeb. I immediately fell completely in love with FakeWeb. However, I have to wonder if there is a downside to using FakeWeb. It seems like mocks are still much more common, so I wonder what I am missing that's wrong with using FakeWeb instead. Is there a certain kind of error you can't cover with Fakeweb or is it something about the TDD or BDD process?

  • 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

  • RESTful design, how to name pages outside CRUD et al?

    - by sscirrus
    Hi all, I'm working on a site that has quite a few pages that fall outside my limited understanding of RESTful design, which is essentially: Create, Read, Update, Delete, Show, List Here's the question: what is a good system for labeling actions/routes when a page doesn't neatly fall into CRUD/show/list? Some of my pages have info about multiple tables at once. I am building a site that gives some customers a 'home base' after they log on. It does NOT give them any information about themselves so it shouldn't be, for example, /customers/show/1. It does have information about companies, but there are other pages on the site that do that differently. What do you do when you have these situations? This 'home-base' is shown to customers and it mainly has info about companies (but not uniquely so). Second case: I have a table called 'Matchings' in between customers and companies. These matchings are accessed in completely different ways on different parts of the site (different layouts, different CSS sheets, different types of users accessing them, etc. They can't ALL be matchings/show. What's the best way to label the others? Thanks very much. =)

  • Ruby Actions: How to avoid a bunch of returns to halt execution?

    - by Alexandre
    How can I DRY the code below? Do I have to setup a bunch of ELSEs ? I usually find the "if this is met, stop", "if this is met, stop", rather than a bunch of nested ifs. I discovered that redirect_to and render don't stop the action execution... def payment_confirmed confirm_payment do |confirmation| @purchase = Purchase.find(confirmation.order_id) unless @purchase.products_match_order_products?(confirmation.products) # TODO notify the buyer of problems return end if confirmation.status == :completed @purchase.paid! # TODO notify the user of completed purchase redirect_to purchase_path(@purchase) else # TODO notify the user somehow that thigns are pending end return end unless session[:last_purchase_id] flash[:notice] = 'Unable to identify purchase from session data.' redirect_to user_path(current_user) return end @purchase = Purchase.find(session[:last_purchase_id]) if @purchase.paid? redirect_to purchase_path(@purchase) return end # going to show message about pending payment end

  • How to define one-to-many connection between a same model through another model

    - by Mekajiki
    I want to define one-to-many relationship as follows; User has one introducer User has many newcomers(who is introduced by the user) Use "Introduction" model instead of adding a column to users table. My table and model definition is as follows; DB Scheme: create_table "introductions", force: true do |t| t.integer "introducer_id" t.integer "newcomer_id" t.datetime "created_at" t.datetime "updated_at" User model: class User < ActiveRecord::Base has_many :introductions, foreign_key: :introducer_id has_many :newcomers, through: :introductions, source: :newcomer belongs_to :introduction, foreign_key: :newcomer_id belongs_to :introducer end Introduction model: class Introduction < ActiveRecord::Base belongs_to :introducer, class_name: 'User' belongs_to :newcomer, class_name: 'User' end This works fine: user1.newcomers.push user2 but, user2.introducer # => nil How can I define belongs_to relationship correctly?

  • 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?

  • OpenID and Authlogic - login and password?

    - by skrat
    How can I get rid of validation messages telling me that: Login is too short (minimum is 3 characters) Login should use only letters, numbers, spaces, and .-_@ please. Password is too short (minimum is 4 characters) Password confirmation is too short (minimum is 4 characters) this happens even before map_openid_registration is called, thus not giving me any chance to fill login with something from returned registration Hash. I would like to have OpenID auto-registration (on login) without requiring user to supply login/password. I also won't make this fields "not required" or "not validated", since I still need them with old school login/password registration. Thank you

  • Paperclip: delete attachment and "can't convert nil into String" error

    - by snitko
    I'm using Paperclip and here's what I do in the model to delete attachments: def before_save self.avatar = nil if @delete_avatar == 1.to_s end Works fine unless @delete_avatar flag is set when the user is actually uploading the image (so the model receives both params[:user][:avatar] and params[:user][:delete_avatar]. This results in the following error: TypeError: can't convert nil into String from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:40:in `dirname' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:40:in `flush_writes' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:38:in `each' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:38:in `flush_writes' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/attachment.rb:144:in `save' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/attachment.rb:162:in `destroy' from /Work/project/src/app/models/user.rb:72:in `before_save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:347:in `send' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:347:in `callback' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:249:in `create_or_update' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2538:in `save_without_validation' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/validations.rb:1078:in `save_without_dirty' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/dirty.rb:79:in `save_without_transactions' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:229:in `send' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:229:in `with_transaction_returning_status' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract/database_statements.rb:136:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:182:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:228:in `with_transaction_returning_status' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:196:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:208:in `rollback_active_record_state!' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:196:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:723:in `create' I assume it has something to do with the avatar.dirty? value because when it certainly is true when this happens.
