  • ruby on rails delajed_job failing with rvm

    - by mottalrd
    I have delayed_job installed and I start the daemon to run the jobs with this ruby script require 'rubygems' require 'daemon_spawn' $: << '.' RAILS_ROOT = File.expand_path(File.join(File.dirname(__FILE__), '..')) class DelayedJobWorker < DaemonSpawn::Base def start(args) ENV['RAILS_ENV'] ||= args.first || 'development' Dir.chdir RAILS_ROOT require File.join('config', 'environment') Delayed::Worker.new.start end def stop system("kill `cat #{RAILS_ROOT}/tmp/pids/delayed_job.pid`") end end DelayedJobWorker.spawn!(:log_file => File.join(RAILS_ROOT, "log", "delayed_job.log"), :pid_file => File.join(RAILS_ROOT, 'tmp', 'pids', 'delayed_job.pid'), :sync_log => true, :working_dir => RAILS_ROOT) If I run the command with rvmsudo it works perfectly If I simply use the ruby command without rvm it fails and this is the output, but I have no idea why this happens. Could you give me some clue? Thank you user@mysystem:~/redeal.it/application$ ruby script/delayed_job start production /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:16:in `kill': Operation not permitted (Errno::EPERM) from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:16:in `alive?' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:125:in `alive?' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:176:in `block in start' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:176:in `select' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:176:in `start' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/daemon-spawn-0.4.2/lib/daemon_spawn.rb:165:in `spawn!' from script/delayed_job:37:in `<main>'

  • Nokogiri parsing Rackspace return using XPath in Rails

    - by Schroedinger
    Hey guys, I'm using Nokogiri to parse a return from the Rackspace API so I'm using their sample code to response = server.get '/customers/'[email protected]_id.to_s+'/domains/', server.xml_format doc = Nokogiri::XML::parse response.body puts "xpath values" doc.xpath("//name").each do |node| puts node.text end As my code to use Nokogiri to return the nodelist of nodes of the element for some reason I seem to have missed something obvious and I just for the life of me cannot get it to parse the list of nodes and return them to me, is there something simple I can do to fix to have it return the list of nodes? Cheers

  • Preventing Rails from opening production.log, when it is deployed with jruby-rack into tomcat.

    - by gregor
    I have to to deploy a Ruby on Rails application to an tomcat application server using jruby-rack. Due to security reasons my customer has the webapps directory mounted read only and he won't changed this. The problem that arises is, that the rails logger wants to open the WEB-INF/log/production.log in write mode. He writes nothing to this file because log4j and friends are configured and working, but rails complains that the file is not readable. Are there any suggestions from preventing rails from opening this file?

  • Rails, Deleting Children without Deleting Parent using :has_many

    - by Dex
    I have a model called MyContainer, which :has_many MyObjects. I want to delete all the MyObjects in the container without having to delete the MyContainer. My model does have :dependent = :destroy, however I don't want to have to delete and re-create the object because it is slower. Something like this does not work: @obj = MyContainer.find_by_id(10) @obj.my_objects.delete_all How can I accomplish this?

  • Are rails timers reliable when using Net::HTTP?

    - by Frank
    Hi All. When reading data from a potentially slow website, I want to ensure that get_response can not hang, and so added a timer to timeout after x seconds. So far, so good. I then read http://ph7spot.com/musings/system-timer which illustrates that in certain situations timer.rb doesn't work due to ruby's implementation of threads. Does anyone know if this is one of these situations? url = URI.parse(someurl) begin Timeout::timeout(30) do response = Net::HTTP.get_response(url) @responseValue = CGI.unescape(response.body) end rescue Exception = e dosomething end

  • Rails route rewriting quesiton

    - by Jonathan
    Hi guys, I think this is an easy question. I am using this useful Flash Document Reader called FlexPaper. I have it embeded in one of my Show pages. But when I click the a link on their tool bar to show the document in a new browser, it points to the following link ... http://0.0.0.0:3000/intels/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf which doesn't work, but if I remove the "intels" from the path so the url looks like: http://0.0.0.0:3000/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf It works fine. My question is what is the best way to handle this. Can you write a route that rewrites a url that starts with intels/FlexPaperViewer.swf and removes the intels prefix? What would that look like? Is there a better option? Thanks! Jonathan

    Hi all, I'm using the field_for form helper with a loop: <% f.fields_for :permissions do |permission_form| %> <tr> <td><%= permission_form.object.security_module.name %><%= permission_form.hidden_field(:security_module_id) %></td> <td><%= permission_form.object.security_module.description %></td> <tr> <% end %> The resulting output of the above code is this: <input id="role_permissions_attributes_0_id" name="role[permissions_attributes][0][id]" type="hidden" value="76" /> <tr> <td>Diary<input id="role_permissions_attributes_0_security_module_id" name="role[permissions_attributes][0][security_module_id]" type="hidden" value="13" /></td> <td>Access to the Diary Module</td> </tr> <!-- next input field then <tr> tag --> The problem with this markup is that the input tag falls outside of the tr tag which there for causes validation issues with XHTML. Does anyone know how I can have the input tag fall inside the tr tag therefore giving me valid XHTML 1.0 STRICT markup? Thanks

  • rails wiki site - article edit highlighting/strikethrough with htmldiff maxes cpu

    - by mark
    Hi I'm implementing a wiki style site and want to highlight changes made to articles between successive versions. Using htmldiff to highlight changes works great, except it is rather cpu intensive. I'm using the awesome vestal_versions plugin for versioning. So how best to handle this? I considered having an on_create callback on version creation create a delayed job that processes and then stores the htmldiff processed article (in the version table row). If this is a good approach, how can I extend vestal_versions without touching the gem? Or maybe there would be a better approach. Any advice is much appreciated. :)

  • Rails 3.1. Cocoon link_to_add_association example needed

    - by BazZy
    pls show any example of using Cocoon's 'link_to_add_association' with html_options. https://github.com/nathanvda/cocoon Documentation says: html_options: extra html-options (see link_to) There are two extra options that allow to conrol the placement of the new link-data: data-association-insertion-node : the jquery selector of the node data-association-insertion-position : insert the new data before or after the given node. But i can not understand what to do, if i want insert partial just before my "add element" link. Not just after parent's div begin. This not gonna work: <%= link_to_add_association "add element", f, :production_years, :position = "after_all" %

  • Rails 3 time output

    - by Oluf Nielsen
    Hi, I'm now working on my output of the feeds I'm taking in from some site. What I'm currently doing is Time, and i want it to be displayed in a maybe, little be special way.. like this.. today, 14:12 yesterday, 15:34 27/12, 15:24 i have this in my code = news.entry_published.strftime("%d/%m, %H:%M") That gives me an error saying undefined method `strftime' for "2010-12-30 19:26:00.000000":String And it dosn't do what i want with the days.. Edit: - @date = DateTime.strptime(news.entry_published, "%Y-%m-%d %H:%M:%S") = @date.strftime("%d/%m, %H:%M") Now works, and gives this output 30/12, 19:26 But i still have to check if it is today, yesterday or just another day. Cheers, Oluf.

  • rails routes for permalink with namespaced class

    - by David
    this one in my routes works perfectly: map.connect ':permalink', :controller = 'pages', :action = 'show' for this class: class PagesController < BackendController and on /xxx/pages it is shown like this: <%= link_to "#{item.link_name}", {:controller = :pages, :action = :show, :permalink = item.permalink} % which will generate a link like "how-to-create-permalinks". but i decided to move the PagesController into a subdirectory so the class is now written like so: class Backend::PagesController < BackendController But how does the route look like now? And how do i display it on the template so it links using the permalink? Thanks!

  • Using Rails Helper Methods within ActionRecord Queries?

    - by Pygmalion
    I have a table of events (in a sqlite3 database for what it's worth) with a column called "when" that contains a timestamp detailing precisely when the event that particular row denotes is set to occur. Right now, I have @events = Event.find(:all) in my controller and I am using template helper methods to calculate where to place each event on my display page based on the day of the week it occurs on. For example: <% if(event.when.wday == 6) %> # DO SOMETHING <% end %> I want to abstract this logic to the controller however. My idea was to do the following: @thursday_events = Event.find(:all, :conditions => ["when.wday=4"]) Obviously (I guess?) this didn't work. Throwing the error "SQLite3::SQLException: near "when": syntax error: SELECT * FROM "events" WHERE (when.wday=4)". I'm assuming this is because I tried to use a helper method within a find condition but I don't know a better way to do this. Any advice? Thanks!

  • Testing Rails Metal With Cucumber/rSpec

    Hi, I'm trying to stub a third party service that my metal talks to. It seems rspec mocks/stubs don't extend all the way to the Metal. When I call stubbed methods on objects, it calls the original one and not the stubbed one. Any idea of how I can have rSpec doubles extend all the way to the metal? Thanks. -Nash
