Hi guys, The functionality I plan on doing is to insert some form elements depending on a number chosen from a select tag. I have a select tag called for number_of_passengers, and i plan to dynamically append new passenger fields for the number chosen. Say I select 2 from number_of_passengers, then 2 forms should appear in a fieldset. ...
I'm trying to setup a very basic id="thisFileName" in my staticMatic project. So far I've managed to apply the following to an /index.html (the HAML output): - @slug = current_page.gsub(/\.html/, '') Which returns "/index". However - I'd like to remove the / at the start so that it reads /index... Any tips or directions for where ...
I heard that HAML has a capture function that can do something like Ruby on Rails's render_to_string, but can't find info on it. Actually, in View, we can use aString = render :partial ... and render actually works the same as render_to_string (as on Rail 2.2.2). But is there also an HAML way of doing it by capture? ...
If post.published? .post / Post stuff Otherwise .post.gray / Post stuff I've implemented this with rails helper and it seems ugly. = content_tag :div, :class => "post" + (" gray" unless post.published?).to_s do / Post stuff Second variant: = content_tag :div, :class => "post" + (post.published? ? "" : " gray") do / Post...
Depending on if a user is signed in or not, I'd like to print a different kind of %body-tag. This is how I currently do it: - if defined? @user %body(data-account="#{@user.account}") %h1 Welcome -# all my content - else %body %h1 Welcome -# all my content As you can see there's a lot of duplicated code in there. H...

Hello! I'm making "user settings form", and stuck with HAML: = form_tag('/') - [1,2,3].each do |i| = check_box_tag "accept#{i}" = submit_tag This results in "syntax error, unexpected kENSURE, expecting $end". The working variant is = form_tag('/') - [1,2,3].each do |i| = check_box_tag "accept#{i}" = s...
I am writing a Rails helper method that will add wrapper html to captured content blocks and replace content_for method, such as - content_for :header do //haml code ..would become - content :header do //haml code In order to do this I am using Haml and Ruby blocks. This is what it looks like def content(name,&block) content_fo...
I use a text area to collect comments from the user. The text area preserves the next line and white space indentation. While displaying the comment in a p tag the next line and white space indentation at the beginning of the line are lost. I enter the following text in the text area: Lorem ipsum dolor sit amet, consectetur adipisic...
I'm doing a brief exercise, condensed below. The issue I'm having is that I'm able to pass a selection of all tickets, but not a selection of one ticket. At / there is no problem listing all the tickets, at endpoint for a ticket I get: NoMethodError at /pi2l9ulnw undefined method `slug' for # I'm relatively new to Ruby and cutting and ...
Does anyone know why %select{:name => "dropdown"} expand » - for say_text in @available_says %option = h say_text in HAML resolves to <select name='dropdown'></select> <option>a</option> <option>b</option> <option>c</option> in HTML? It's stymieing my dropdown completely and the documentation all says "That should work." I can't i...
I have a model Ticket which has n Comments belonging to it (many to one relationship). The issue is that I can not render any of the comments nor does the form post the comments to the database. I can kinda sorta do this from irb. I can add comments to tickets.comments, but I cannot pull individual comments - I can pull up the collect...
I'm trying to accomplish the following content in source code: <div id="box<%=id%>"></div> Without escaping any signs in Haml. %div{ :id => "box_<%=id%>" } produces <div id='box_<%=id%>'></div> Right now the only way I can do this with Haml is to use :plain filter and hardcode HTML without using any View Helpers. How can I...
I'm converting an old program over to haml and I've got a problem with my custom formbuilder. The problem is simply adding a line feed between a fields label and input tag. Here is the original FormBuilder: # Custom FormBuilder class SuperFormBuilder < ActionView::Helpers::FormBuilder # Create an array of helpers to override with o...
I have this code in my controller: @cats = DirCat.all And this in a view: %ul#menu = @cats.each do |item| %li = link_to item.title, "/catalog/#{item.id}/" And get strange output: <ul id='menu'> <li> <a href="/catalog/4/">hello</a> </li> <li> <a href="/catalog/5/">hello 1</...
I'm a big Haml/Sass fan. Right now I work with a designer who prefers Erb and doesn't speak Haml. I find that working with Erb is slowing me down considerably, and it doesn't seem fair that he should have to pay for that time (he's the client & I'm paid hourly). The erb->haml converter works quite well these days, but I don't know if t...
In my Jekyll blog I use the include tag to put the contents of a file into the document. However if I attempt to do this with a HAML based document the indentation of the included text is wrong. :preserve does not work because it requires indentation. Is there a way to specify a block of text without depending on indentation? %html %b...
Hi, Is there a way to get your SCSS files to automatically generate new CSS each time a file is changed as part of Rails, without having to use sass --watch? Or is this just meant to happen anyway? By this I mean having rails do the watching for you, or maybe if it can recompile all SCSS every page load in development that is fine too....
I just upgraded to Rails3, Ruby 1.9.2 and the latest HAML gem. This code used to work: = allowed? do = link_to('New', new_video_path) Now allowed? yields 0. It works if I do: = allowed?{ link_to('New', new_video_path) } What gives? ...
Hi, my mac just broke and I had to migrate to an Ubuntu machine. I am working on an app that is already on production on an Ubuntu machine as well.
