haml

问题 I have problem getting my sass work with my haml template. Recently i have following code in my main sinatra.rb application: require 'sinatra' require 'dm-core' require 'dm-migrations' require 'haml' require 'sass' require 'shotgun' set :views, :sass => 'views/css', :haml => 'template', :default => 'views' helpers do def find_template(views, name, engine, &block) _, folder = views.detect { |k,v| engine == Tilt[k] } folder ||= views[:default] super(folder, name, engine, &block) end end get '

问题 I think there may be a bug in Haml? Or something I missed The form tag supposed to enclose the input element, but it doesn't. <form accept-charset="UTF-8" action="/remote_focus/kill_running_task" data-remote="true" method="get"></form> <tr> <td>... Where I expect it is <form accept-charset="UTF-8" action="/remote_focus/kill_running_task" data-remote="true" method="get"> <tr> <td>... </form> This is my haml file, iterate each task from an array, - @running_tasks.each do |running_task| = form

问题 I am creating a simple ajax feature into my application where a user can increase a "like count" through a link. I have managed to get the link to run my controller code and the browser is getting a response back, but the response is not executed. The like link is in partial: .likes .like_up = link_to( image_tag('/images/thumb_up.png'), '/like/' + question.id.to_s, :remote => true) #like_count = 22# question.likecount .like_down = link_to( image_tag('/images/thumb_down.png'), '/dislike/' +

问题 I have an application (rails 3.2) with haml (3.1.4) emails. In the email template I wanted to use link_to, but apparently none of those 4 is working in production: #{link_to(my_models_url)} = link_to(my_models_url) / @url set to my_models_url #{link_to(@url)} = link_to(@url) On development mode everything works fine, but in production, I keep getting the following error: No route matches {} actionpack (3.2.0) lib/action_dispatch/routing/route_set.rb:503:in `raise_routing_error' It works when

问题 I'm trying to use load_class to load mthaml as I understood it's necessary for performance reasons. This is the MtHaml library. https://github.com/arnaud-lb/MtHaml It's namespaced everywhere so getting it working with load_class natively hits the first hurdle. Then it gets instantiated through Autoloader.php which does namespace MtHaml; class Autoloader { static public function register() { spl_autoload_register(array(new self, 'autoload')); } static public function autoload($class) { if

问题 I am currently making a script that analyses some genetic data and then produce the output on a coloured Word document. The script works, however, one method in the script is badly written, the method that creates the Word document. The method creating the document creates a standalone HTML file, which is then saved with a 'docx' extension, which allows me to give different parts of the document different styles. Below is the bare minimum to get this to work. It includes some sample input

问题 I'm trying to create an appointment scheduler using jQuery (UI), Haml, and Rails. I'm making a set of tabs for the next 4 weeks. #schedule %ul - @schedule.each_index do |i| %li %a{:href => "#schedule-#{i}"} #{@schedule[i][:week_range]} - @schedule.each_index do |i| %div{:id => "#schedule-#{i}"} %p test Ideally, this would create a set of tabs such as (December 27th-January Nth) as the tab title and then have "test" in each box. In applications.js I have: $('#schedule').tabs(); However, this

问题 I have a button (in a haml view) that I want to use to go to another controller/action. I am more accustomed to PHP than rails. What I have tried works but does not feel like the rails way. Here are my 3 ways. Can anyone offer suggestions? I'd particularly like to see the way the button with a javascript onclick handler would be done. %p =link_to "Edit", edit_user_registration_path(@user) %button.btn.btn-success.doEdit{:onclick => "window.location='#{edit_user_registration_path(@user)}'"}
