  • Using Routing helpers in a Rake task

    - by trobrock
    I have a rake task that sends out the next 'x' invitations to join a beta it uses this code: desc "This will send out the next batch of invites for the beta" task :send_invites => :environment do limit = ENV['limit'] c = 0 invitation = Invitation.all(:conditions => { :sent_at => nil, :sender_id => nil }, :limit => limit).each do |i| Mailer.deliver_invitation(i, register_url(i.token)) c.increment! end puts "Sent #{c} invitations." end I need to pass in the 'register_url' to the Mailer in order for the link to show up in the email, but since this is running from a rake task and not from a request it does not have a access to the helper methods. What is the best way of achieving this?

  • .save puts NULL in id field in Rails

    - by mathee
    Here's the model file: class ProfileTag < ActiveRecord::Base def self.create_or_update(options = {}) id = options.delete(:id) record = find_by_id(id) || new record.id = id record.attributes = options puts "record.profile_id is" puts record.profile_id record.save! record end end This gives me the correct print out in my log. But it also says that there's a call to UPDATE that sets profile_id to NULL. Here's some of the output in the log file: Processing ProfilesController#update (for 127.0.0.1 at 2010-05-28 18:20:54) [PUT] Parameter: {"commit"=>"Save", ...} ?[4;36;1mProfileTag Create (0.0ms)?[0m ?[0;1mINSERT INTO `profile_tags` (`reputation_value`, `updated_at`, `tag_id`, `id`, `profile_id`, `created_at`) VALUES(0, '2010-05-29 01:20:54', 1, NULL, 4, '2010-05-29 01:20:54')?[0m ?[4;35;1mSQL (2.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mSQL (0.0ms)?[0m ?[0;1mBEGIN?[0m ?[4;35;1mSQL (0.0ms)?[0m ?[0mCOMMIT?[0m ?[4;36;1mProfileTag Load (0.0ms)?[0m ?[0;1mSELECT * FROM `profile_tags` WHERE (`profile_tags`.profile_id = 4) ?[0m ?[4;35;1mSQL (1.0ms)?[0m ?[0mBEGIN?[0m ?[4;36;1mProfileTag Update (0.0ms)?[0m ?[0;1mUPDATE `profile_tags` SET profile_id = NULL WHERE (profile_id = 4 AND id IN (35)) ?[0m I'm not sure I understand why the INSERT puts the value into profile_id properly, but then it sets it to NULL on an UPDATE. If you need more specifics, please let me know. I'm thinking that the save functionality does many things other than INSERTs into the database, but I don't know what I need to specify so that it will properly set profile_id.

  • Set a datetime for next or previous sunday at specific time

    - by Marc
    I have an app where there is always a current contest (defined by start_date and end_date datetime). I have the following code in the application_controller.rb as a before_filter. def load_contest @contest_last = Contest.last @contest_last.present? ? @contest_leftover = (@contest_last.end_date.utc - Time.now.utc).to_i : @contest_leftover = 0 if @contest_last.nil? Contest.create(:start_date => Time.now.utc, :end_date => Time.now.utc + 10.minutes) elsif @contest_leftover < 0 @winner = Organization.order('votes_count DESC').first @contest_last.update_attributes!(:organization_id => @winner.id, :winner_votes => @winner.votes_count) if @winner.present? Organization.update_all(:votes_count => 0) Contest.create(:start_date => @contest_last.end_date.utc, :end_date => Time.now.utc + 10.minutes) end end My questions: 1) I would like to change the :end_date to something that signifies next Sunday at a certain time (eg. next Sunday at 8pm). Similarly, I could then set the :start_date to to the previous Sunday at a certain time. I saw that there is a sunday() class (http://api.rubyonrails.org/classes/Time.html#method-i-sunday), but not sure how to specify a certain time on that day. 2) For this situation of always wanting the current contest, is there a better way of loading it in the app? Would caching it be better and then reloading if a new one is created? Not sure how this would be done, but seems to be more efficient. Thanks!

  • PayPal Payments Pro Sandbox requires membership?

    - by Kevin
    Do I need to pay the $30 just to play around in the sandbox for Website Payments Pro? I'm trying to get Active Merchant working in Rails, and it's giving me an error "invalid merchant configuration"... after digging around a bit it says I need to "accept the billing agreement" and/or sign up for the Payments Pro first. So, do I need to pay the $30 just to test in sandbox? Or is there another workaround for this error?

  • Rails Metaprogramming: How to add instance methods at runtime?

    - by Larry K
    I'm defining my own AR class in Rails that will include dynamically created instance methods for user fields 0-9. The user fields are not stored in the db directly, they'll be serialized together since they'll be used infrequently. Is the following the best way to do this? Alternatives? Where should the start up code for adding the methods be called from? class Info < ActiveRecord::Base end # called from an init file to add the instance methods parts = [] (0..9).each do |i| parts.push "def user_field_#{i}" # def user_field_0 parts.push "get_user_fields && @user_fields[#{i}]" parts.push "end" end Info.class_eval parts.join

  • I want to use the fleximage gem and s3 for storage, but don't want dev/qa/test env's to use s3

    - by Kevin Bedell
    I have a rails app that I'm going to host on engineyard and want to store image files on s3. But I don't know if I want all developer machines to beusing s3 for storage of all our test and dev images. Maybe it's not an issue -- but it seems like a waste to have everyone storing all our images in s3. I've heard of some ppl who store images on s3 'hacking' dev environments to store images locally on the file system -- and then using s3 in prod only. What are other people doing?

  • Get string value from http response with Mechanize

    - by Gearóid
    Hi, I'm currently integrating facebook into my current app and I've succeeded in retrieving the access_token using the following code: url="#{url}?#{client_id}&#{client_secret}&#{code}&#{redirect_uri}&type=client_cred" agent = Mechanize.new page = agent.get(url) The page object above has a body which contains text something along the lines of access_token=XXXXX I just want to pull out the access_token value. I can get the entire string simply by writing: page.body But I was wondering is there a way to get the access_token value without resorting to regular expressions etc? Thanks.

  • HTTPS and HTTParty - Timeout and EOF

    - by ferparra
    Hi all, I'm trying to post something to an HTTPS resource, but it seems it doesn't work. My code look something like this: require 'httparty' class MyClass include HTTParty base_uri "https://mydomain.com:8085/search" basic_auth 'admin', 'changeme' format :xml def mymethod self.class.post('/job', :query => {:search => "*"}) end end As you can see, I've defined an URI with 'https' included, so it should set the use_ssl property for the Net::HTTPS library automatically. For some reason, Net::HTTP is requested, and I never get in touch with the server, so I end up with an EOF. Any clues?

  • How can I make the Rails 3 router localize URLs using localization files?

    - by edgerunner
    What I'd like to be able to do is: in config/routes.rb resources :posts in config/locale/en.yml en: resources: posts: "posts" new: "new" edit: "edit" in config/locale/tr.yml tr: resources: posts: "yazilar" new: "yeni" edit: "duzenle" and get I18n.locale = :en edit_post_path(3) #=> /posts/3/edit I18n.locale = :tr edit_post_path(3) #=> /yazilar/3/duzenle I'd also like Rails to match any of these routes anytime and pass the associated locale in the params hash such that when I navigate to /yazilar , the request should be routed to the posts#index action with the :tr locale in the params hash. Any simple or complex way of doing that?

  • is this a secure approach in ActiveRecords in Rails?

    - by Adnan
    Hello, I am using the following for my customers to unsubscribe from my mailing list; def index @user = User.find_by_salt(params[:subscribe_code]) if @user.nil? flash[:notice] = "the link is not valid...." render :action => 'index' else Notification.delete_all(:user_id => @user.id) flash[:notice] = "you have been unsubscribed....." redirect_to :controller => 'home' end end my link looks like; http://site.com/unsubscribe/32hj5h2j33j3h333 so the above compares the random string to a field in my user table and accordingly deletes data from the notification table. My question; is this approach secure? is there a better/more efficient way for doing this? All suggestions are welcome.
