Multiple multi-line HAML blocks

问题 Using the (intentionally) strange multi-line format for HAML, I'd like to have the following lines in my template: = call_to_helper :foo1 => 'bar1', :foo2 => 'bar2', :foo3 => 'bar3', | :foo4 => 'bar4', :foo5 => 'bar5' | -# and = call_to_helper :foo1 => 'bar1', :foo2 => 'bar2', :foo3 => 'bar3', | :foo4 => 'bar4', :foo5 => 'bar5' | However, they can not run up against one another, or they are read as one single multi-line block. -# This fails: = call_to_helper :foo1 => 'bar1', :foo2 => 'bar2',

Partial HAML templating in Ruby without Rails

阅读更多关于 Partial HAML templating in Ruby without Rails

I really don’t need the overhead of Rails for my very small project, so I’m trying to achieve this just using just plain Ruby and HAML. I want to include another HAML file inside my HAML template. But I haven’t found a good—or really usable—way of doing this. For example, I have these two HAML files: documents.haml %html %body = include(menu.haml) body %article … menu.haml %ul %li %a whatever … Include is obviously not the way to go here. But it does a nice job describing what I’m trying to achieve in this example. I've done this before, just for a quick-and-dirty template producer. The

Ruby methods within Javascript within HAML

I have a jQuery script that adds a new field to a form, and this field contains dynamic information from an array. The problem is that I can't figure out how to add an array.each to populate the options of the select field within the javascript without breaking the HAML indentation and causing errors. Here is my best attempt that does not work: %script(type="text/javascript") $('#mylink').click(function() { $('#mylink').after('<select> - myarray.each do |options| <option value="#{options.id}">#{options.name}</option> </select>); )}; Also tried it with the :javascript filter with no luck.

HAML: Create container/wrapper element only if condition is true

阅读更多关于 HAML: Create container/wrapper element only if condition is true

问题 Longshot, but I'm wondering if there's any way to do something like this: %p # ONLY SHOW THIS IF LOCAL VARIABLE show_paras IS TRUE = name In other words, it always shows the content inside, but it only wraps a container around it if (some-condition) is true. 回答1: You could use raw html, but then you'd have to have the if statement both at the beginning and end: - if show_paras <p> = name - if show_paras </p> Assuming you're doing more than just = name , you could use a partial: - if show

Why does a rails app on heroku serve assets via all.css and locally via individual files

阅读更多关于 Why does a rails app on heroku serve assets via all.css and locally via individual files

问题 I'm a rails newbie, I've been trying to figure out what is going on with the stylesheets_link_tag on heroku. If I use = stylesheet_link_tag "style", :cache => true heroku uses "all.css" and does not pick up the stylesheet, but if I use = stylesheet_link_tag "style", :cache => false it serves the stylesheet using its name "style.css". Why? 回答1: This is the result of calling :cache => true on your stylesheet link tag. :cache => true takes all of the stylesheets provided and concatenates them
