  • How to update attributes without validation

    - by Brian Roisentul
    I've got a model with its validations, and I found out that I can't update an attribute without validating the object before. I already tried to add on => :create syntax at the end of each validation line, but I got the same results. My announcement model have the following validations: validates_presence_of :title validates_presence_of :description validates_presence_of :announcement_type_id validate :validates_publication_date validate :validates_start_date validate :validates_start_end_dates validate :validates_category validate :validates_province validates_length_of :title, :in => 6..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :place, :in => 0..50, :on => :save validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true My rake task does the following: task :announcements_expiration => :environment do announcements = Announcement.expired announcements.each do |a| #Gets the user that owns the announcement user = User.find(a.user_id) puts a.title + '...' a.state = 'deactivated' if a.update_attributes(:state => a.state) puts 'state changed to deactivated' else a.errors.each do |e| puts e end end end This throws all the validation exceptions for that model, in the output. Does anybody how to update an attribute without validating the model?

  • Support for IMAP IDLE in ruby

    - by Asaxena
    Ok, I have been suck on it for hours. I thought net/imap.rb with ruby 1.9 supported the idle command, but not yet. Can anyone help me in implementing that? From here, I though this would work: class Net::IMAP def idle cmd = "IDLE" synchronize do tag = generate_tag put_string(tag + " " + cmd) put_string(CRLF) end end def done cmd = "DONE" synchronize do put_string(cmd) put_string(CRLF) end end end But imap.idle with that just return nil.

  • mysterious difference between rake test and ruby

    - by standup75
    Here is the mysterious: I have a scope which looks like this (in Image.rb) scope :moderate_all, delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") Note that delegates is another scope that I am defining before moderate_all When I leave it like this, I can run my test that checks if an image has been "checked-out" it is not available anymore. I don't put the code of the test, because it does not matter actually. With this code, when I run "rake test" it fails, but if I do "ruby test/unit/image_test.rb" it works! I was thinking I am starting to have a bad day. Then I tried scope :moderate_all, lambda { delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") } And "rake test" passes! So my problem is solved, but why?

  • What can be inside a class that derive from OmniAuth?

    - by Richard77
    I have the following class class Identity < OmniAuth:: Identity:: Models:: ActiveRecord attr_accessible :email, :name, :password_digest, :password, :password_confirmation end I wonder if the above properties are the only ones allowed for a class that derive from a OmniAuth. I wish I could add some more like FirstName, LastName, age, gender, and so on. Do I need to create an other model for those properties or can I just add them to the Identity model? Thanks for helping.

  • Unique view count.

    - by alokswain
    I have a collection of links which are being displayed on the index page. Whenever a user clicks a link I want to keep a track of the number of unique views. I know it can be done by tracking the ips whenever a click happens by request.remote_ip and then the link of the page that was clicked. Is there any better approach ? Any plugins etc.

  • how to save related models with non-null foreign key

    - by Fortress
    I have a model called user which has_one email. I put the foreign key (NOT NULL) inside users table. Now I'm trying to save it in the following way: @email = Email.new(params[:email]) @email.user = User.new(params[:user]) @email.save This raises a db exception, because the foreign key constraint is not met (NULL is inserted into email_id). How can I elegantly solve this or is my data modeling wrong?

  • has_many :through name suggestions

    - by user1084769
    I have three models, user, achievement, badge and I plan on using has_many :through instead of has_many_and_belongs_to since I will have a few extra fields in the join tables. According to a Railscast I watched, using this method requires coming up with new model names and not user_badge or user_achievement. For my User Achievement join what do you think of Accomplishment? For my User Badge join what do you think of Distinction?

  • Nested Resource - How to pass needed keys, and attribute to update?

    My nested resources are working for form_for updates, but I have a few toggles that I need to setup to change a status field. So I am using link_to, and accessing the url helper. link_to "toggle", edit_project_expense_path(@project[:id],expense_item[:id]) routes.rb resources :projects do resources :expenses end match '/submit_expense/:id' => 'expenses#submit_expense', :as => 'submit_expense' rake routes edit_project_expense GET /projects/:project_id/expenses/:id/edit(.:format) expenses#edit My question is: How can I also send along :approval_status = "1", with my link_to?

  • Displaying count for current_user 'likes' on a 'question' in questions/show.html.erb view

    - by bgadoci
    I have an application that allows for users to create questions, create answers to questions, and 'like' answers of others. When a current_user lands on the /views/questions/show.html.erb page I am trying to display the total 'likes' for all answers on that question, for the current_user. In my Likes table I am collecting the question_id, site_id and the user_id and I have the appropriate associations set up between user, question, answers and likes. I think I just need to call this information the right way, which I can't seem to figure out. All of the below is taking place in the /views/questions/show.html.erb page. I have tried the following: <% div_for current_user do %> You have liked this question <%= @question.likes.count %> times <% end %> Which returns all the 'likes' for the question but not filtered by current_user You have liked this question <%= current_user.question.likes.count %> times Which gives an error of 'undefined method `question' You have liked this question <%= @question.current_user.likes.count %> times Which gives an error of 'undefined method `current_user' I have tried a couple of other things but they don't make as much sense as the above to me. What am I missing?

  • gems, bundle command, and ruby not found in new terminal window

    - by user3579987
    So I installed ruby with rvm, ran a bundle install and installed a bunch of gems, etc. It all works just fine in the original terminal window I did all of this in but I opened up a new terminal window and now I'm getting errors like bundle: command not found and gem command not found. I tried doing a symbolic link for the gem command but then when I do gem list it displays a much shorter list of my local gems and not at all the ones I need for bundle install. Is there something I need to do to configure bash or rvm so that it recognizes that I did indeed install all the gems I have installed? name@crunchbang:~/ug_research_portal$ which gem /home/name/.rvm/rubies/ruby-2.1.1/bin/gem name@crunchbang:~/ug_research_portal$ which ruby /home/name/.rvm/rubies/ruby-2.1.1/bin/ruby And in ~/.bashrc: GEM_HOME="/home/name/.rvm/gems/ruby-2.1.1" GEMGLOBAL_HOME="/home/ name/.rvm/gems/ruby-2.1.1@global" export PATH=$PATH:$GEM_HOME/bin:$GEMGLOBAL_HOME/bin:$HOME/.rvm/bin Edit: Looks like my $PATH is somehow wrong? bash: /home/name/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/home/name/.rvm/gems/ruby-2.1.1/bin:/home/name/.rvm/gems/ruby-2.1.1@global/bin:/home/name/.rvm/bin/: No such file or directory which is odd since ls for /home/name/.rvm/bin and /home/name/.rvm/gems/ruby-2.1.1@global/bin and /home/name/.rvm/gems/ruby-2.1.1/bin work just fine Psych, I was just doing $PATH instead of echo "$PATH" which was giving me the No such file or directory error. The original problem still stands though.

  • Compare a DateTime to the current date

    - by looloobs
    Hi I am trying to use a condition on events when the start_at DateTime is equal to or greater than Today's date. I want to list upcoming events, but clearly they are not upcoming if they have already passed. I have: @appointments = Event.find(:all, :conditions => ['move_id = ? AND start_at = ?', @move.id, Date.today]) I think I may be comparing apples and oranges here. It doesn't throw and error, just doesn't do what it is supposed to. Help! Thanks in advance.

  • Can an ActiveRecord before_save filter halt the save without halting the transaction?

    - by Michael Boutros
    Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes: before_filter :ignore_changes_if_sample def ignore_changes_if_sample if self.sample? return false end end Thanks!

  • Why in the hell is this happening?

    - by user202411
    I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).
