问题 This question already has answers here : Injecting variable values into javascript and HAML in RoR (2 answers) Closed 5 years ago . Hey is there a way I can do this in haml? :javascript var Tab = <%= @tab %> I could just add a helper I guess like: <script> var Tab = '<%= @tab %>' </script> But it'd be nice to use HAML! 回答1: You can use the string interpolation syntax ( #{...} ) : :javascript var tab = #{@tab} Take care of correctly escaping, however. 回答2: This is a terrible way to structure

问题 I want to insert a div.row every three blocks in order to wrap three span together for the following haml snippet. But this code insert a <div class="row"></div> rather than wrap the .span4 . - data.apps.applications.each_with_index do |app, index| - if index%3 == 0 .row # This is the line I want to insert .span4 How could I do that in haml or in this case, erb is more suitable? 回答1: I think what you want is something like this: -data.apps.applications.each_slice(3) do |apps| .row -apps.each

问题 I am building a website with Middleman. I am storing a lot of information in data files, as I am going to use the same information on multiple pages. (Partials wouldn't work for me, as same text from data can be used with different HTML tags or be slightly modified for different pages.) I want to write markdown in data files and then use it within HAML templates for specific pages. When I try to create relative links to other pages while using a reference to other data file, resulting HTML is

问题 If I create an XML element in HAML: %tag{:b => "b", :a => "a"} I get this output: <tag a="a" b="b"/> Is it possible to keep the ordering of the attributes in HAML? I need this for a client-side code to display values in certain order and don't want to pass extra information on the client just to maintain ordering. 回答1: It's not possible with HAML because it's a hash. 来源： https://stackoverflow.com/questions/7766240/preserve-attribute-ordering-in-haml

问题 I have a button_to call in my Rails 4 haml file that looks like this = button_to("Click Me", action: "click", class: "btn btn-primary") However, the class: "btn btn-primary" code snippet isn't working properly, and my button isn't changing. I've also tried the old Ruby syntax of :class => "btn btn-primary" , but that doesn't seem to do the trick. Any help would be greatly appreciated. 回答1: You need to make sure the second and third parameters to button_to are separate. Currently the action

问题 Trying to come up with a more compact way of expressing this conditional in HAML and Ruby, perhaps with a ternary operator: - if @page.nil? %br (nothing yet) - else %br #{@page.name} (looking for similar approach as per Neat way to conditionally test whether to add a class in HAML template) Your help would be appreciated :) 回答1: The code you have makes the text a child of the <br> element; that is not desirable. What you really meant, I think, was: %br - if @page.nil? (nothing yet) - else #{

问题 I use HAML in my rails project for my html templates. I would like to figure out if its possible to divide a very long line and make it a couple of rows: %a.open-service{href: '#', data: { service_name: service.description, balance_type: "coinsurance", total: service.a_total_billed - service.a_rejected - service.a_not_covered, discount: service} } As you can see, I just want to have an anchor with href and some data-attributes, and making it one-line won't be a pretty code. But when I do it

问题 I'm trying to move my full-stack rails app over to Angular a page at a time. I'm using ui-router (https://github.com/angular-ui/ui-router) and angular-rails-templates (https://github.com/pitr/angular-rails-templates). I assumed the nghaml extension would allow me to continue to use rails helpers such as link_to, paths, etc. in my haml so just copied and pasted my haml page into the template; in an ideal world I would now be at a point where one page was being served client-side and every
