  • Nokogiri changing custom elements

    - by dagda1
    Hi, I have sample html that I have marked up with some special tags that will be used by a different program, an example of the html is below. You should note the <START:organization>..<END> elements. <html> <head/> <body> <ul> <li> <START:organization> Advanced Integrated Pest Management <END> </li> <li> <START:organization> American Bakers Association <END> </li> </ul> </body> </html> I wanted to use nokogiri to preprocess the html to easily remove irrelevant tags like <script>. I created the following extension to the nokogiri document class: module Nokogiri module HTML class Document def prepare_html xpath("//script").remove to_html.remove_new_lines end end end end The problem is that nokogiri is changing the <START:organization> element to <organization>. Is there anyway that I can preserve the htnl to maintain my custom markup tags? Thanks Paul

  • are fixtures loaded when using the sql dump to create a test database

    - by Josh Moore
    Because of some non standard table creation options I am forced to use the sql dump instead of the standard schema.rb (i.e. I have uncommented this line in the environment.rb config.active_record.schema_format = :sql). I have noticed that when I use the sql dump that my fixtures do not seem to be loaded into the database. Some data is loaded into it but, I am not sure where it is coming from. Is this normal? and if it is normal can anybody tell me where this other data is coming from?

  • Does it make sense to fragment cache static partials

    - by ash34
    Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

  • how to refactor tricky logic involving consecutive sets?

    - by keruilin
    The rule at work here is that users can be awarded badges for a streak of 10, 20, and 30. If the user has a streak over 30, such as 40 or 50, then the logic must be that it only awards a 10-streak badge for 40 and a 20-streak badge for 50, and so on. def check_win_streak(streak) badge = 10 while badge < badge::MAX_STREAK_BADGE_SIZE do # MAX_STREAK_BADGE_SIZE = 30 if streak < badge then break end if (streak % badge == 0) then award_streak_badge(badge) end badge += 10 end end

  • From Sinatra Base object. Get port of application including the base object

    - by Poul
    I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up. I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port. I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running. In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method. a) any ideas on how to get the port? I have the host. b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-) //in my Sinatra::Base code. lets call it register_me.rb RegisterMe < Sinatra::Base configure do //save host and port information to database end get '/check_status' //return status end //in my web service code require register_me //at this point, sinatra will initialize the RegisterMe object and call configure post ('/blah') //example of a method for this particular web service end

  • Nokogiri Not Parsing File

    - by Jesse J
    I'm using Nokogiri to parse pepXML files from different peptide search engines. I have two pepXML files, both of which appear, inasmuch as I can tell, to be of correct format, and puts Nokogiri::XML(IO.read(file)) will output the whole XML file for both files. The problem is, doc.xpath("any valid xpath") will parse the tag from one of the files, but not the other. No errors are given, so I have no idea why it won't parse. Anyone know of any reasons why Nokogiri wouldn't parse something out?

  • link_to for calling an action, instead of a button_to

    - by Brian Roisentul
    I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.

  • Is there a SaaS for logging user activity?

    - by JoshL
    In almost every app that I build I create some kind of user log table to log various activities that my actual USERS (not visitors, but someone with an account) perform on the site. This is primarily used for customer service issues to allow me to pull up a record of the pages and actions that a user has visited. The downside to this is the size of the UserLogs table. It gets immense. I'm not sure if it is common practice or not for others to log INDIVIDUAL (not aggregate like Google Analytics) user behavior to a database, but if it is I'm wondering if any form of a SaaS exists to help offload this task? I essentially need a RESTful API that lets me store and retrieve individual user activity quickly and securely. Anyone know of any or am I the only one who has this issue?

  • collection_select not working as expected

    - by kgb
    First time I've come to use collection_select in a project and I've hit a wall with it. A Profile has_one Team, Team has_many Profile. In my view for editing profiles I have this. <td><%= f.collection_select(:team_id, @team, :id, :title) %></td> Which populates the drop down with titles of teams as expected. The couple of examples I have read seem to use it in a very similar way. I can't figure out when the profile is saved why it isn't populating the team_id field in my DB. In the development log the team_id is being passed. Processing ProfilesController#update (for 127.0.0.1 at 2010-03-28 22:49:16) [PUT] Parameters: {"commit"=>"Update", "profile"=>{"dob(1i)"=>"2010", "second_name"=>"", "dob(2i)"=>"3", "role"=>"", "dob(3i)"=>"28", "project"=>"", "specialties"=>"", "about"=>"", "team_id"=>"1", "status"=>"", "first_name"=>""}, "authenticity_token"=>"sdTiFPGj9JCO3OEge5EGNGxZbQSsq9ME5LP342EBjyc=", "id"=>"3"} The update controller is the standard scaffold one, this has worked fine for all other additions to the profile model I'd made previously. Am I missing something obvious?

  • Can I combine atom feeds from seperate resources into one?

    - by stephemurdoch
    I have two resource for which I would like to generate feeds; they are called podcasts and posts. The problem is that when I include the auto_discovery_link in my templates, I have to add one for each of the two atom feeds that I've generated. The reason why this is a problem is that there are now two feeds for users to choose from, and most people probably won't realise that they need both so will only pick one. Is there a way to combine atom feeds from different resources into one atom feed? Like application.atom or something? I'm using builder to generate the feed.

  • ActiveRecord field normalization

    - by Bill
    I feel bad asking this question, as I thought I knew enough about Activerecord to answer this myslef. But such is the way of having SO available ... I'm trying to remove the commas from a field in a model of mine, I want the user to be able to type a number , ie 10,000 and that number be stored in the database as 10000. I was hoping that I could do some model-side normalization to remove the comma. I don't want to depend on the view or controller to properly format my data. I tried ; before_validation :normalize def normalize self['thenumber'] = self['thenumber'].to_s.gsub(',','') end no worky :(

  • acts_as_taggable_on and auto_complete returning no results

    - by Sean Johnson
    I'm using acts_as_taggable_on in a model, and am trying to implement the auto_complete plugin. It seems as though I have everything hooked up correctly, but the search isn't returning any results. Here's what I have so far: In the view: <%= text_field_with_auto_complete(:link, :tag_list, {}, {:tokens => ','}) %> In the controller: def auto_complete_for_link_tag_list @tags = Link.tag_counts_on(:tags).where('tags.name LIKE ?', params[:link][:tag_list]) render :inline => "<%= auto_complete_result(@tags, 'name') %>", :layout => false logger.info "#{@tags.size} tags found." end The logger keeps returning 0 tags, and nothing shows up in the view (yeah, the layout includes the javascript defaults). Any thoughts or advice would be awesome.

  • How do I configure integration tests using rspec 2?

    - by Jamie Monserrate
    I need to have different settings for my unit tests and different settings for my integration tests. Example For unit tests, I would like to do WebMock.disable_net_connect!(:allow_localhost => true) And for integration tests, I would like to do WebMock.allow_net_connect! Also, before the start of an integration test, I would like to make sure that solr is started. Hence I want to be able to call config.before(:suite) do SunspotStarter.start end BUT, only for integration tests. I do not want to start my solr if its a unit test. How do I keep their configurations separate? Right now, I have solved this by keeping my integration tests in a folder outside the spec folder, which has its own spec_helper. Is there any better way?

  • Devise authenticating with username instead of email

    - by teknull
    I'm new to Devise and have it working fine by using an email address as the authentication key. However, I have a use case which requires a username instead and I can't seem to get it working. I've added a string column, "username" to the users table, changed the fields from :email to :username in the sign-in form, and have changed the authentication key in devise.rb to :username yet when I go to sign in I'm met with this prompt: "Please enter an email address". What am I doing wrong? **new.html.erb** <div><%= f.label :username %><br /> <%= f.email_field :username %></div> **User.rb** class User < ActiveRecord::Base # Include default devise modules. Others available are: # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :authentication_keys => [:username] # Setup accessible (or protected) attributes for your model attr_accessible :email, :password, :password_confirmation, :remember_me, :username # attr_accessible :title, :body end **devise.rb** config.authentication_keys = [ :username ]

  • disabling transactional fixtures in Rspec has no effect

    - by Dia
    Due to a legacy database I'm using, I'm stuck with MySQL using MyISAM, which means my tables don't support transactions. This is causing the tests to fail, since table data generated (I'm using factory_girl for fixtures) by the tests are not reverted for each scenario. I discovered that Rspec exposes the config.use_transactional_fixtures config setting in spec_helper.rb. which is set to true by default. When I set it to false, I don't see any effect on my tests; they still fail due to duplicate records. Isn't that setting supposed to automatically unroll any changes made to the DB? Or am I supposed to do that manually?

  • Conditionally hide a portion of a partial when viewed from another controller

    - by user284194
    I'm using a partial from my messages controller in my tags controller. The portion in question looks like this: <% unless message.tag_list.nil? || message.tag_list.empty? %> <% message.tags.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> <% end %> Is there a way to hide this portion of the partial only when it is viewed from the tags controller? Thanks for reading my question.

  • Passing arguments to an Rspec SpecTask

    - by Bayard Randel
    Rake allows for the following syntax: task :my_task, :arg1, :arg2 do |t, args| puts "Args were: #{args}" end I'd like to be able to do the same, but with RSpecs SpecTask. The following unfortunately fails: desc "Run example with argument" SpecTask.new('my_task'), :datafile do |t, args| t.spec_files = FileList['cvd*_spec.rb -datafile=#{args}'] t.spec_opts = ["-c -f specdoc"] end Is it possible to achieve this with a SpecTask, or is there an alternative approach?
