liquid

I've been searching for a template engine to allow users to create lessons and exercises online easily. Seems like Liquid is the most popular for use in Rails. Can Liquid users easily create rails forms? Normally I create forms in ERB with: <%= form_for(@lesson) do |f| %> <% if @lesson.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@lesson.errors.count, "error") %> prohibited this lesson from being saved:</h2> <ul> <% @lesson.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <div>lots of fields</div> <% end %> Rails will automatically

I'm working on a single-page scroll-to webdesign, and can't get this code to work. What I'm trying to do is get the screen height of the user through JavaScript.

If I passed explicite: {% for post in site.categories['cat1'] %} <li><a href="{{ post.url }}">{{ post.title }}

How can I use Jekyll to test for the existence of a file? To clarify, I want to run an {% if %} statement to check if an image file exists with the same name as the page I am on. On my page in the YAML front matter: ---- reference-design: true ---- In my layout: {% if page.reference-design %} {% assign filename = page.path | remove_first: '.html' %} <!-- How can I check if file actually exists? --> <img src="images/reference_designs/{{ filename }}.png"> {% endif %} As of Jekyll 2, all site files are available via site.static_files . You can use this to check if a file exists. For example: {%
