问题 In my model I have: def self.chart_data(start, slut) if start.nil? start = 2.weeks.ago end if slut.nil? slut = Date.today end range = start.to_date..(slut.to_date + 1.day) if start.to_date.beginning_of_month.to_s != slut.to_date.beginning_of_month.to_s kliks = count( :group => 'date(month)', :conditions => { :created_at => range } ) # CREATE JSON DATA FOR EACH MONTH - PROBLEM HERE (range).map(&:beginning_of_month).uniq.map(&:to_s).each do |month| { created_at: month, clicks: kliks[month] || 0

问题 I have a pretty straight forward app with a couple tweaks to Devise. First I created a Registrations controller that class RegistrationsController < Devise::RegistrationsController inherits from Devise. I created this controller so that I could edit users without re-supplying passwords. https://gist.github.com/1514687 I also did this in my routes: devise_for :users, :controllers => { :registrations => "registrations" }` The signup works fine but when I call the following: <p class="edit"><%=

问题 all I want is duplicate an existing record. It should render new form with populated data and let me 'Create' this new record. def clone @agreement = Agreement.find_by_slug!(params[:id]) @agreement.clone respond_to do |format| format.html { render action: "new", notice: 'Agreement was successfully cloned.' } end end My Model def clone self.dup() self.slug = nil end I get this error: No route matches {:action=>"show", :controller=>"agreements", :format=>nil, :id=>#<Agreement id: 1, date: "2011

问题 I need a regex to match something like "4f0f30500be4443126002034" and "4f0f30500be4443126002034>4f0f31310be4443126005578" but not like "4f0f30500be4443126002034>4f0f31310be4443126005578>4f0f31310be4443126005579" 回答1: Try: ^[\da-f]{24}(>[\da-f]{24})?$ [\da-f]{24} is exactly 24 characters consisting only of 0-9, a-f. The whole pattern is one such number optionally followed by a > and a second such number. 回答2: I think you want something like: /^[0-9a-f]{24}(>[0-9a-f]{24})?$/ That matches 24

问题 I have a very simple model using Mongoid. I've added the use of Redcarpet to parse the MD and store it. However during update_attributes it is throwing an exception. Running the model and running the update through rails c works fine. class Post include Mongoid::Document field :contents_markdown field :contents key :title before_create :markdown before_save :markdown protected def markdown if self.contents_markdown self.contents = Redcarpet.new(self.contents_markdown).to_html.html_safe end

问题 I am using Ruby on Rails 3.2.9 and Ruby 1.9.3-p125. After my previous question I ended up that I have an issue on metaprogramming a self-implemented acts_as_customizable plugin since the related code has side effects on other classes than that "acting as customizable". To summarize the issue: the acts_as_customizable method stated for an Article model "internally" (through metaprogramming) adds a customize method to a Comment model and, in order to save time, Rails doesn't load all those

问题 I run a Rails 3 application on Windows XP and it fails sometimes with the following error: This causes the WEBrick server to shutdown. When I start the server again, sometimes the page loads as expected and sometimes it fails again with the same error. I noticed that the error appears when I change one of the JavaScript files that belong to the loaded page. What could be the reason for this ? How could I debug this ? My Ruby version is: ruby 1.9.2p0 (2010-08-18) [i386-mingw32] . 回答1: You need

问题 I am implementing an up-voting system on an app I am building very similar to the one here on stackoverflow. When a user clicks upvote or downvote, an ajax request is sent to one of my controllers which them updates a couple of tables. Once that is done, I use the respond_to to routes to a js.erb file that executes jquery to update the user display. However, the jquery is not being executed. When I lick upvote/downvote, the controller code executes properly (I can see it in the rails console)
