haml

问题 I am using bootstrap modals and Ruby on Rails. I was able to display the modal fine but I am having trouble using Javascript to manipulate the contents of the modal. I am not sure what I am doing wrong but I was not able to use Javascript to impact the contents of the modal at all, to the point that I started wondering if there are such a thing as different stack levels on the DOM elements or whether even the modal contents are part of the DOM. Here is my app/views/home/index.haml: - url =

问题 From what I understand, link_to is used for get methods, and button_to is used for post methods. On the other hand, I was told that with HTML5 semantics, <button> is used for any type of clickable...well, button. In the case I have a clickable button that sends a user to a form to fill out, should I create a button_to or a link_to ? 回答1: It's simpler that you think. That methods are Rails helpers and don't have anything to do with haml. Yes, one method is for get and another for post methods.

问题 I have a rails create action which send back some jquery in a file: create.js.erb var appearance = $("<%= escape_javascript(render(:partial => @appearance)) %>").effect("highlight", {color: '#E6ff00'}, 2000); $("#sortable").append(appearance); $("#new_appearance")[0].reset(); I have started using HAML and want to know how I should be converting this. Can I use js.haml? If so what should the markup look like? 回答1: Actually, returning JS in HAML is pretty easy, just use the :plain filter and

问题 Right now, I do a get '/' do set :base_url, "#{request.env['rack.url_scheme']}://#{request.env['HTTP_HOST']}" # ... haml :index end to be able to use options.base_url in the HAML index.haml. But I am sure there is a far better, DRY, way of doing this. Yet I cannot see, nor find it. (I am new to Sinatra :)) Somehow, outside of get , I don't have request.env available, or so it seems. So putting it in an include did not work. How do you get your base url? 回答1: A couple things. set is a class

问题 I want to serve static HTML pages using nginx . Then, I will use jQuery to update DIVs, SPANs, etc via AJAX calls from a Padrino server. I like creating my web pages in HAML because it's easier but in production, I don't want to serve HAML templates. Just raw, HTML at the speed of nginx. Is there an easy way to do this? What would be ideal would be a service that automatically renders HAML, partials, etc into the public folder that nginx could serve. 回答1: Simple, add padrino-cache to your app
