  • NameError: uninitialized constant Nokogiri::HTML::DocumentFragment

    - by Mike Sutton
    About three hours ago I started seeing the above error in my production server. It comes from a call to the sanitize gem: vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:276:in 'load_missing_constant' vendor/rails/activerecord/lib/../../activesupport/lib/active_support/dependencies.rb:468:in `const_missing' vendor/gems/sanitize-1.2.0/lib/sanitize.rb:91:in `clean!' vendor/gems/sanitize-1.2.0/lib/sanitize.rb:84:in `clean' vendor/gems/sanitize-1.2.0/lib/sanitize.rb:49:in `clean' app/helpers/application_helper.rb:28:in `display_none' app/views/main/_blogs.html.erb:13:in `_run_erb_47app47views47main47_blogs46html46erb' The error only occurs on the production server (linux), not my development machine (windows) I tried rolling back my latest deployment but it didn't fix it. I've updated to sanitize 1.2.0 (which was the latest version brought down by gem update sanitize, though I note my host is running 1.3.6. Can anyone provide any clues to help fix this?

  • find(:all) and then add data from another table to the object

    - by Koning Baard XIV
    I have two tables: create_table "friendships", :force => true do |t| t.integer "user1_id" t.integer "user2_id" t.boolean "hasaccepted" t.datetime "created_at" t.datetime "updated_at" end and create_table "users", :force => true do |t| t.string "email" t.string "password" t.string "phone" t.boolean "gender" t.datetime "created_at" t.datetime "updated_at" t.string "firstname" t.string "lastname" t.date "birthday" end I need to show the user a list of Friendrequests, so I use this method in my controller: def getfriendrequests respond_to do |format| case params[:id] when "to_me" @friendrequests = Friendship.find(:all, :conditions => { :user2_id => session[:user], :hasaccepted => false }) when "from_me" @friendrequests = Friendship.find(:all, :conditions => { :user1_id => session[:user], :hasaccepted => false }) end format.xml { render :xml => @friendrequests } format.json { render :json => @friendrequests } end end I do nearly everything using AJAX, so to fetch the First and Last name of the user with UID user2_id (the to_me param comes later, don't worry right now), I need a for loop which make multiple AJAX calls. This sucks and costs much bandwidth. So I'd rather like that getfriendrequests also returns the First and Last name of the corresponding users, so, e.g. the JSON response would not be: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3 } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4 } } ] but rather: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3, "firstname": "Jon", "lastname": "Skeet" } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4, "firstname": "Mark", "lastname": "Gravell" } } ] I thought of a for loop in the getfriendrequests method, but I don't know how to implement this, and maybe there is an easier way. It must also work for XML. Can anyone help me? Thanks

  • Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

    - by brad
    I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?

  • Rails - how can I capture the URL that directed to the current action in my app?

    - by sa125
    Hi - I need to see what page a request came from in my controller so I could be able to redirect back to it. For example, if I'm on a page showing a specific product (say /products/1) and it has a link to its vendor (/vendors/12), I want to be able to detect inside the vendors_controller that I came to that page from /products/1. Is there a simple way in Rails to achieve this, so that I could access it via params or session? thanks.

  • Evaluating points in time by months, but without referencing years in Rails

    - by MikeH
    FYI, There is some overlap in the initial description of this question with a question I asked yesterday, but the question is different. My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product. We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date. Including years doesn't make sense for our model. So we're using the option: discard_year => true When you use discard_year => true, Rails sets a year in the database, it just doesn't appear in the views. Rails sets all the years to either 0001 or 0002 in our app. Yes, we could make it 2009 and 2010 or any other pair. But the point is that we want the months and days to function independent of a particular year. If we used 2009 and 2010, then those dates would be wrong next year because we don't expect these records to be updated every year. My problem is that we need to dynamically evaluate the availability of products based on their relationship to the current month. For example, assume it's March 15. Regardless of the year, I need a method that can tell me that a product available from October to January is not available right now. If we were using actual years, this would be pretty easy. For example, in the products model, I can do this: def is_available? (season_start.past? && season_end.future?) end I can also evaluate a start_date and an end_date against current_date However, in setup I've described above where we have arbitrary years that only make sense relative to each other, these methods don't work. For example, is_available? would return false for all my products because their end date is in the year 0001 or 0002. What I need is a method just like the ones I used as examples above, except that they evaluate against current_month instead of current_date, and past? and future months instead of years. I have no idea how to do this or whether Rails has any built in functionality that could help. I've gone through all the date and time methods/helpers in the API docs, but I'm not seeing anything equivalent to what I'm describing. Thanks.

  • Using respond_to ... format.json and jQuery Form Plugin by malsup

    - by Topher Fangio
    Hello all, I'm having a tad bit of trouble getting the jQuery Form Plugin to work properly with a file-upload field. When I use the plugin to submit the form without a file-upload field, the format.json portion of the respond_to do |format| block is called properly. However, by adding the file-upload field, it only executes the format.html portion which makes my javascript code think that an error has occurred. Has anyone run into this before or know a way to force the plugin to always use json? Alternatively, can I modify the url that the plugin uses to force Rails to render the json? Thanks very much for any help! Code below: # app/controllers/details_controller.rb def create @detail = Detail.new(params[:detail]) style = params[:detail_style].to_sym || :thumb data = { :id => '5', :url => 'test.rails' } respond_to do |format| if @detail.save flash[:notice] = 'Your image has been saved.' data = { :id => @detail.id, :url => @detail.data.url(style) } format.html { redirect_to :action => 'index' } format.json { render :json => "<textarea>#{data.to_json}</textarea>", :status => :created } else format.html { render :action => 'new' } format.json { render :json => @detail.errors, :status => :unprocessable_entity } end end end /* app/views/sidebar/_details.html.erb (excerpt) */ <% form_for(Detail.new, :html => { :multipart => true } ) do |f| %> <%= hidden_field_tag 'detail_style', 'thumb' %> <%= f.label :image, "Recent Images" %> <%= f.file_field :image%> <p> <%= f.submit "Upload" %> </p> <% end %> <script> $(document).ready(function() { var options = { dataType: 'json', success: function(json, statusText) { console.log("success: " + json); }, error: function(xhr, statusText, errorThrown) { console.log("error: " + xhr.responseText); } }; $('#new_detail').ajaxForm(options); });

  • Sqs vs SqsGen2 using RightScale right_aws GEM

    - by Fitter Man
    I'm trying to use the right_aws (1.10.0) GEM with Rails, and I've reduced my problem to a 3-line irb session. The following works require 'rubygems' require 'right_aws' sqs = RightAws::Sqs.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") while this fails require 'rubygems' require 'right_aws' sqs = RightAws::SqsGen2.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") with NameError: uninitialized constant RightAws::SqsGen2. I see the class definition in the GEM source, the documentation is old but seems accurate, but I can't figure out what I'm doing wrong. And while you're at it, is there any reason if I'm building something new, I'd want to use the older interface?

  • 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!

  • Redirect Output of Capistrano

    - by Eric Lubow
    I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

  • Capistrano configuration

    - by Eli
    I'm having some issues with variable scope with the capistrano-ext gem's multistage module. I currently have, in config/deploy/staging.rb. set(:settings) { YAML.load_file("config/deploy.yml")['staging'] } set :repository, settings["repository"] set :deploy_to, settings["deploy_to"] set :branch, settings["branch"] set :domain, settings["domain"] set :user, settings["user"] role :app, domain role :web, domain role :db, domain, :primary => true My config/deploy/production.rb file is similar. This doesn't seem very DRY. Ideally, I think I'd like everything to be in the deploy.rb file. If there were a variable set with the current stage, everything would be really clean. UPDATE: I found a solution. I defined this function in deploy.rb: def set_settings(params) params.each_pair do |k,v| set k.to_sym, v end if exists? :domain role :app, domain role :web, domain role :db, domain, :primary => true end end Then my staging.rb file is just set_settings(YAML.load_file("config/deploy.yml")['staging'])

  • Rails paperclip problem

    - by palani
    I have uploaded the video into my rails application by using thoughtbot-paperclip then the video is converted into "flv" format by using ffmpeg. For your reference here I specified some of my model sample code: model.rb: has_attached_file :source,:styles => {:thumb => "137x85>" } If i specified :url or :path option it doesn't worked correctly. In my view I played my video by using the following line: <%= @model.source.url.gsub(/\?.*/,'')%> If i use <%= @model.source.url%>, the video is not played. When do the puts for video url it shows me the video URL as /source/original/sample/sample.fly?22000009. I knew that the last portion is a timestamp, but i want to use <%= @model.source.url%>. What's my mistake here can any one correct me please?

  • Using jQuery UI with Rails

  • Automatically render changed partials in webby

    - by Tomas Sedovic
    I have a webby page and I'm have a layout that all my pages are rendered to. That layout uses a partial for navigation (in HAML): = render(:partial => "navigation", :locals => {:some => "stuff"} ) The problem is that when I change the _navigation partial, neither webby nor webby autobuild recognize the change and they don't re-render the pages. I've solved this by setting the dirty: true flag in the layout, but that makes all the pages re-render every time -- even when nothing changed. I know that this is not that big a deal, but still: is there a way so that when you change partial, webby recognizes this and renders only the affected pages (as it does with everything else)?

  • Rails ActiveResource Associations

    - by brad
    I have some ARes models (see below) that I'm trying to use associations with (which seems to be wholly undocumented and maybe not possible but I thought I'd give it a try) So on my service side, my ActiveRecord object will render something like render :xml => @group.to_xml(:include => :customers) (see generated xml below) The models Group and Customers are HABTM On my ARes side, I'm hoping that it can see the <customers> xml attribute and automatically populate the .customers attribute of that Group object , but the has_many etc methods aren't supported (at least as far as I can tell) So I'm wondering how ARes does it's reflection on the XML to set the attributes of an object. In AR for instance I could create a def customers=(customer_array) and set it myself, but this doesn't seem to work in ARes. One suggestion I found for an "association" is the just have a method def customers Customer.find(:all, :conditions => {:group_id => self.id}) end But this has the disadvantage that it makes a second service call to look up those customers... not cool I'd like my ActiveResource model to see that the customers attribute in the XML and automatically populate my model. Anyone have any experience with this?? # My Services class Customer < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :customer end # My ActiveResource accessors class Customer < ActiveResource::Base; end class Group < ActiveResource::Base; end # XML from /groups/:id?customers=true <group> <domain>some.domain.com</domain> <id type="integer">266</id> <name>Some Name</name> <customers type="array"> <customer> <active type="boolean">true</active> <id type="integer">1</id> <name>Some Name</name> </customer> <customer> <active type="boolean" nil="true"></active> <id type="integer">306</id> <name>Some Other Name</name> </customer> </customers> </group>

  • Rails - operation outside of a rollback

    - by Brian Armstrong
    I have a before_create filter that checks if people are posting too many comments. If they are I want to flag their account. class Comment < ActiveRecord::Base before_create :check_rate_limit def check_rate_limit comments_in_last_minute = self.user.comments.count(:conditions => ["comments.created_at > ?", 1.minute.ago]) if comments_in_last_minute > 2 user.update_attribute :status, "suspended" return false end true end end The before filter returns false to stop the comment from being created. The problem is that this triggers a ROLLBACK which also undoes the changes I made to the user model. What's the correct pattern to accomplish this? Specifically: running a check each time an object is created and being able to edit another model if the check fails.

  • 'sript/console test' with spork and rspec not loading the whole environment?

    - by TheDeeno
    I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

  • Limit a user to view only associated records in rails

    - by trobrock
    I have an application with three Models (Profile - SubModel - SubSubModel) chained together with has many relationships. I am trying to limit a user, after logging in, to only retrieving records that are associated with their Profile. I am very new to rails and this is what I had been trying in the Profile model has_many :submodels, :conditions => {:profile_id => self.id} but this is returning an empty data set when calling with Profile.find_by_id(1).submodels, how else could I achieve what I am trying to do. Or should I handle this in the controller or view instead, I thought it sounded well suited for the model to handle this.

  • Authorize.net Parameters with activemerchant

    - by rpflo
    I'm using authorize.net and activemerchant in a rails app. When I make a purchase authorize.net sends back an email with information about the purchase. I should be able to send them the billing and shipping address information and have that returned in the email, but it's not returning any of the information, obviously I've got the varable names wrong, anybody know what they should be? I've been pouring over the authorize.net api docs and activemerchant's but can't find what I need. My purchase method on an orders model looks like this: def purchase purchase_options = { :ip => ip_address, :first_name => first_name, :last_name => last_name, :address => billing_street_address, :city => billing_city, :state => billing_state, :country => "US", :zip => billing_zip, :ship_to_first_name => first_name, :ship_to_last_name => last_name, :ship_to_address => shipping_street_address, :ship_to_city => shipping_city, :ship_to_state => shipping_state, :ship_to_country => "US", :ship_to_zip => shipping_zip } response = GATEWAY.purchase(price_in_cents, credit_card, purchase_options) # other transaction stuff response.success? end
