ruby-on-rails-3.1

问题 Using coffeescript, jQuery, and sprockets in rails 3.1 the coffeescript files are compiled in to blocks like: (function() { var a; var b; var c; foo = function() { alert("foo"); } bar = function() { alert("bar"); } }).call(this); This seems to move functions foo and bar out of global scope, so bar can be called by foo, but neither can be called from the html code. When I try to call foo from a select onchange element, I get a "Can't find variable: foo". The workaround right now is to move all

问题 I am trying to implement Ransack for a search feature on my website. I tried watching the Railscasts on Ransack and got a pretty good idea of how to implement it. But I am running into an issue that I can't seem to figure out. In the Index action of my Users controller, I have the following code: def index @users = User.same_city_as(current_user) end @users is an ActiveRecord::Relation object. @users is essentially capturing all the users who belong to the same city as the current_user .

问题 I have an application where I have a Shipment model. I have created a view that allows me to create shipments and view shipments in a table based layout. Everything lies in the index.html.erb because all actions are done through ajax. When a shipment is created, the status is "OPEN" by default. Later on when a bill of lading is printed, the status will change to "PRINTED". My goal is to create another view that lists only the open shipments allowing an operator to print the bill of lading

问题 I have the following models: #equipment.rb class Equipment < ActiveRecord::Base belongs_to :odometer_type has_many :odometers end #odometer.rb class Odometer < ActiveRecord::Base belongs_to :equipment # I am currently doing this to find the last mileage entered (which is wrong too cause I want the mileage from the max date entered) def self.current_reading(equipment) all.where(:equipment_id => equipment.id).max(:mileage) end end This looks even worse in the view, like this: = @equipment

问题 I have a form that works fine until I add the tags for styling (I am using twitter bootstrap). The app is Rails 3.1 and I am on a mac. Here is a form that works fine with no issues: <%= form_for @user do |f| %> <% if @user.errors.any? %> <div class="alert-message error"> <h2>Form is invalid</h2> <ul> <% for message in @user.errors.full_messages %> <li><%= message %></li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.label :email %> <%= f.text_field :email %> </div> <div class=

问题 I thought I had the assets pipeline figured out, but not any more. I have a stylesheet named clients.css.scss .client { .list_view { width: 650px; height: 500px; overflow: auto; table { width: 650px; border: solid 2px #999999; border-collapse: collapse; thead tr { background: image-url('list-view-header.png') repeat-x; } thead tr:first-child { background-image: none; } } } } Every time I try to precompile it in production I keep getting a "file.png isn't precompiled" error. bundle exec rake

问题 I would like to enable WebDav for Rails 3.1 application, where I use Devise for authentication and CanCan for authorization. So far I turned on WebDav and works fine.

I have a bunch of user objects: def index @users = User.all @user = current_user end that I need to edit in a form. They all have roles which will be edited on the form. The form is rendered in a partial, and nothing shows up, just 'admin form' plaintext. users/_admin.html.erb admin form <% form_for "user[]", :url => users_path do |f| %> <ul> <li class="layout"> <div class="header">
