  • AJAX in Rails - doing simple looping to update information when available

    - by Acidburn2k
    I am trying to get put out a simple site, which would pool the database every few seconds and update the information on the page dynamicly, when theres something new inserted. I am farily new to ruby, but I understand the whole concept of RJS, link_to_function and soforth. The question is, what is the best way how to implement some kind of simple loop, which would run after the page is loaded and update the DOM if there is something new to display. Thanks in advance for any tips!

  • Rails: Getting rid of "X is invalid" validation errors

    - by DJTripleThreat
    I have a sign-up form that has nested associations/attributes whatever you want to call them. My Hierarchy is this: class User < ActiveRecord::Base acts_as_authentic belongs_to :user_role, :polymorphic => true end class Customer < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end class Employee < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end I have some validation stuff in these classes as well. My problem is that if I try to create and Customer (or Employee etc) with a blank form I get all of the validation errors I should get plus some Generic ones like "User is invalid" and "Customer is invalid" If I iterate through the errors I get something like: user.login can't be blank User is invalid customer.whatever is blah blah blah...etc customer.some_other_error etc etc Since there is at least one invalid field in the nested User model, an extra "X is invalid" message is added to the list of errors. This gets confusing to my client and so I'm wondering if there is a quick way to do this instead of having to filer through the errors myself.

  • Rails Cache Sweeper and Model Callback Firing

    - by Topher Fangio
    Hey guys, I have the following classes: class Vigil < ActiveRecord::Base after_update :do_something_cool private def do_something_cool # Sweet code here end end class NewsFeedObserver < ActionController::Caching::Sweeper observe Vigil def after_update # Create a news feed entry end end Everything works as expected. The after_update in the sweeper requires that the do_something_cool method in the model has finished before it can run properly. The problem is that the after_update in the sweeper is being called before (or perhaps at the same time as) the do_something_cool callback and it's causing problems. Does anyone know how to force the after_update in the sweeper to fire after the model callback? Is there better way to achieve this?

  • Ruby on Rails - f.error_messages not showing up

    - by Brian Roisentul
    Hi, I've read many posts about this issue but I never got this to work. My model looks like this: class Announcement < ActiveRecord::Base validates_presence_of :title, :description end My controller's create method(only its relevant part) looks like this: def create respond_to do |format| if @announcement.save flash[:notice] = 'Announcement was successfully created.' format.html { redirect_to(@announcement) } format.xml { render :xml => @announcement, :status => :created, :location => @announcement } else @announcement = Announcement.new @provinces = Province.all @types = AnnouncementType.all @categories = Tag.find_by_sql 'select * from tags where parent_id=0 order by name asc' @subcategories= '' format.html { render :action => "new" } #new_announcement_path format.xml { render :xml => @announcement.errors, :status => :unprocessable_entity } end end end My form looks like this: <% form_for(@announcement) do |f| %> <%= error_messages_for 'announcement' %> <!--I've also treid f.error_messages--> ... What am I doing wrong?

  • Rails app + gmail smtp + heroku hosting + godaddy domain

    - by sagivo
    i'm trying to define a way to send emails using gmail. it all works fine on localhost but when i deploy to heroku nothing happens. i guess it has something to do with GoDaddy MX records? here is what i tried: ActionMailer::Base.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :domain => "gmail.com", :user_name => "my_user", :password => "my_pass", :authentication => "plain", :enable_starttls_auto => true } i can't change the GoDaddy MX records since i'm forwording some emails from there to my Gmail account. am i missing something? EDIT- it turns out the problem was with my Gmail account. all i needed to turn off the 2-step verification. Problem solved.

  • Ruby on Rails: attr_accessor for submodels

    - by williamjones
    I'm working with some models where a lot of a given model's key attributes are actually stored in a submodel. Example: class WikiArticle has_many :revisions has_one :current_revision, :class_name => "Revision", :order => "created_at DESC" end class Revision has_one :wiki_article end The Revision class has a ton of database fields, and the WikiArticle has very few. However, I often have to access a Revision's fields from the context of a WikiArticle. The most important case of this is probably on creating an article. I've been doing that with lots of methods that look like this, one for each field: def description if @description @description elsif current_revision current_revision.description else "" end end def description=(string) @description = string end And then on my save, I save @description into a new revision. This whole thing reminds me a lot of attr_accessor, only it doesn't seem like I can get attr_accessor to do what I need. How can I define an attr_submodel_accessor such that I could just give field names and have it automatically create all those methods the way attr_accessor does?

    Hi, If I have an object say @user and I want to render only certain fields in it say first_name and last_name(I'm using AMF) render :amf => @user how do I do that? I know I can use :select when doing the 'find' but I need to use the other field at the server side but don't want to send them with AMF to the client side and I don't want to do a second 'find' Thanks, Tam

    - by Danny McClelland
    Hi Everyone, I have created a custom action within one of my controlers as follows: # GET /kases/discharge/1 # GET /kases/discharge/1.xml def discharge @kase = Kase.find_by_jobno(params[:id]) respond_to do |format| format.html { } # discharge.html.erb format.xml { render :xml => @kase } format.pdf { render :layout => false } prawnto :prawn => { :background => "#{RAILS_ROOT}/public/images/discharge.png", :left_margin => 0, :right_margin => 0, :top_margin => 0, :bottom_margin => 0, :page_size => 'A4' } end end For the edit actions etc the link would be link_to edit_kase_path(@kase) Is there a way of linking to the discharge action already, or do I have to make a custom route? Thanks, Danny

  • Capistrano 3, Rails 4, database configuration does not specify adapter

    - by Kazmin
    When I start cap production deploy it fails like this: DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/releases/20131025212110 && (RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/myapp_rake assets:precompile ) DEBUG [4ee8fa7a] rake aborted! DEBUG [4ee8fa7a] database configuration does not specify adapter You can see that "RAILS_ENV=" is actually empty and I'm wondering why that might be happening? I assume that this is the reason for the latter error that I don't have a database configuration. The deploy.rb file is below: set :application, 'myapp' set :repo_url, '[email protected]:developer/myapp.git' set :branch, :master set :deploy_to, '/home/deploy/myapp/releases' set :scm, :git set :devpath, "/home/deploy/myapp_development" set :user, "deploy" set :use_sudo, false set :default_env, { rvm_bin_path: '~/.rvm/bin' } set :keep_releases, 5 namespace :deploy do desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do # Your restart mechanism here, for example: within release_path do execute " bundle exec thin restart -O -C config/thin/production.yml" end end end after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do within release_path do end end end after :finishing, 'deploy:cleanup' end?

  • Ruby on Rails App not starting in production mode

    - by Ermin
    Everything works fine in development mode, but when I try to start my app in production mode (RAILS_ENV=production script/server) I get the following error: /opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/conditions.rb:81:in `method_missing': protected method `scope' called for #<Class:0x7f41de524410> (NoMethodError) from /opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/association_conditions.rb:19:in `method_missing' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/association_ordering.rb:27:in `method_missing' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/ordering.rb:30:in `method_missing' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/or_conditions.rb:28:in `method_missing' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:1959:in `method_missing_without_paginate' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/will_paginate-2.3.12/lib/will_paginate/finder.rb:170:in `method_missing' from /opt/ruby1.8/lib/ruby/gems/1.8/gems/acts_as_commentable-3.0.0/lib/comment_methods.rb:12:in `included' from .../app/models/comment.rb:2:in `include' from .../app/models/comment.rb:2 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'...

  • Dynamic select menu Rails, Javascript HABTM

    - by Jack
    Hi, I am following a tutorial in one of Ryan Bates' Railscasts here. Basically I want a form where there are 2 drop down menus, the contents of one are dependent on the other. I have Years and Courses, where Years HABMT Courses and Courses HABTM Years. In the tutorial, the javascript is as follows: var states = new Array(); <% for state in @states -%> states.push(new Array(<%= state.country_id %>, '<%=h state.name %>', <%= state.id %>)); <% end -%> function countrySelected() { country_id = $('person_country_id').getValue(); options = $('person_state_id').options; options.length = 1; states.each(function(state) { if (state[0] == country_id) { options[options.length] = new Option(state[1], state[2]); } }); if (options.length == 1) { $('state_field').hide(); } else { $('state_field').show(); } } document.observe('dom:loaded', function() { countrySelected(); $('person_country_id').observe('change', countrySelected); }); Where I guess country has many states and state belongs to country. I think what I need to do is edit the first for statement to somehow loop through all of the courses for each year_id, but don't know how to do this. Any ideas? Thanks

  • Rails ActiveRecord: Find All Users Except Current User

    - by SingleShot
    I feel this should be very simple but my brain is short-circuiting on it. If I have an object representing the current user, and want to query for all users except the current user, how can I do this, taking into account that the current user can sometimes be nil? This is what I am doing right now: def index @users = User.all @users.delete current_user end What I don't like is that I am doing post-processing on the query result. Besides feeling a little wrong, I don't think this will work nicely if I convert the query over to be run with will_paginate. Any suggestions for how to do this with a query? Thanks.

  • Rails created_at find condition...

    - by Dustin Brewer
    I'm attempting to sum daily purchase amounts for a given user. @dates is an array of 31 dates. I need the find condition to compare a date from the array to the created_at date of the purchases. What I'm doing below compares the exact DateTime for the create_at column. I need it to look at the day itself, not the DateTime. How can I write this so created_at is in between the date from the array? <% @dates.each do |date| %> <%= current_user.purchases.sum(:amount, :conditions = ["created_at = ?", date]) % <% end %

  • How to store private pictures and videos in Ruby on Rails

    - by TK
    Here's a story: User A should be able to upload an image. User A should be able to set a privacy. ("Public" or "Private"). User B should not be able to access "Private" images of User A. I'm planning to user Paperclip for dealing with uploads. If I store the images under "RAILS_ROOT/public/images", anyone who could guess the name of the files might access the files. (e.g., accessing http://example.com/public/images/uploads/john/family.png ) I need to show the images using img tags, so I cannot place a file except public. How can I ensure that images of a user or group is not accessible by others?

  • Ruby on Rails - Currency : commas causing an issue.

    - by easement
    Looking on SO, I see that the preferred way to currency using RoR is using decimal(8,2) and to output them using number_to_currency(); I can get my numbers out of the DB, but I'm having issues on getting them in. Inside my update action I have the following line: if @non_labor_expense.update_attributes(params[:non_labor_expense]) puts YAML::dump(params) The dump of params shows the correct value. xx,yyy.zz , but what gets stored in the DB is only xx.00 What do I need to do in order to take into account that there may be commas and a user may not enter .zz (the cents). Some regex and for comma? how would you handle the decimal if it were .2 versus .20 . There has to be a builtin or at least a better way. My Migration (I don't know if this helps): class ChangeExpenseToDec < ActiveRecord::Migration def self.up change_column :non_labor_expenses, :amount, :decimal, :precision => 8, :scale => 2 end def self.down change_column :non_labor_expenses, :amount, :integer end end

  • Help me understand Rails eager loading

    - by aaronrussell
    I'm a little confused as to the mechanics of eager loading in active record. Lets say a Book model has many Pages and I fetch a book using this query: @book = Book.find book_id, :include => :pages Now this where I'm confused. My understanding is that @book.pages is already loaded and won't execute another query. But suppose I want to find a specific page, what would I do? @book.pages.find page_id # OR... @book.pages.to_ary.find{|p| p.id == page_id} Am I right in thinking that the first example will execute another query, and therefore making the eager loading pointless, or is active record clever enough to know that it doesn't need to do another query? Also, my second question, is there an argument that in some cases eager loading is more intensive on the database and sometimes multiple small queries will be more efficient that a single large query? Thanks for your thoughts.

  • Creating records using RJS in rails

    - by Elliot
    Hey Everyone, so I've watched http://railscasts.com/episodes/43-ajax-with-rjs but I have a question: In my view I have the following: <div id="testly"> <%= render :partial => "test" %> </div> This works. Using create.rjs to change the content in this div, I have the following in my create.rjs file: page.replace_html :testly, :partial = 'test' Simply put, this should just refresh the partial right? But its not working... Would love any suggestions!
