I'm currently working on a menu for an hexo.io site using data from a YAML file and EJS. My point is to generate a menu with sections and subsections directly from the data included in the YAML file.
The yaml file in _data/menu.yml
sections:
Section1:
Section2:
section1:
Activate:
url: /activate
First steps:
url: /first-steps
My ejs file
<% for (var section in site.data.menu.sections) { %>
<ul>
<li>
<%= section %>
<% for (var i in site.data.menu.section) { %>
<ul>
<li><%= i %></li>
</ul>
<% } %>
</li>
</ul>
<hr>
<% } %>
My goal is to reuse the section variable in the second loop so that I can get a menu displaying :
Section1
Activate
First steps
Section2
Until now, I couldn't find how to properly insert this variable in the loop conditions. And I do not wish to hard code section names in the second loop.
Thanks for your input.
Found a way to do it unifying everything. it could still be optimised but works for me so I post it in case others have the same issue:
YAML
sections:
section1:
title: Section 1
sub:
Activate: /activate
First steps: /first-steps
section2:
title: Section 2
EJS
<% for (var i in site.data.menu.sections) { %>
<ul>
<li>
<%= site.data.menu.sections[i].title %>
<% for (var j in site.data.menu.sections[i].sub) { %>
<ul>
<li><%= j %></li>
</ul>
<% } %>
</li>
</ul>
<hr>
<% } %>

I am trying to add a dynamic class to a link_to in Rails 7. I have the following code, but it's not inserting the appropriate content based on the request.env["PATH_INFO"]...
<ul>
<% %w[blog headlines network].each do |nav_link| %>
<%= added_class = request.env["PATH_INFO"] == nav_link ? "nav_current" : nil %>
<li class="btn"><%= link_to "#{nav_link}".capitalize, "/#{nav_link}", id: "nav_main", class: "btn btn_nav #{added_class}" %></li>
<% end %>
</ul>
However, the resulting HTML is:
<ul>
<li class="btn"><a id="nav_main" class="btn btn_nav " href="/blog">Bog</a></li>
<li class="btn"><a id="nav_main" class="btn btn_nav " href="/headlines">Headlines</a></li>
<li class="btn"><a id="nav_main" class="btn btn_nav " href="/network">Network</a></li>
</ul>
As you can see, the added_class doesn't get inserted. Any ideas?
request.env['PATH_INFO'] contains a leading / (at least on Rails 7; and IIRC on previous versions as well)
That means that if you are visiting localhost:3000/blog, request.env['PATH_INFO'] is /blog, not blog.
The following code should fix it:
<ul>
<% %w[blog headlines network].each do |nav_link| %>
<% added_class = request.env["PATH_INFO"] == "/#{nav_link}" ? "nav_current" : nil %>
<li class="btn"><%= link_to "#{nav_link}".capitalize, "/#{nav_link}", id: "nav_main", class: "btn btn_nav #{added_class}" %></li>
<% end %>
</ul>
Ok, so the following code does what I wanted it to. It injects a custom class into the link tag so that I can track the current button and style it differently... :
<ul>
<% %w[blog headlines network].each do |nav_link| %>
<% add_class = request.env['PATH_INFO'] == "/#{nav_link}" ? "nav_current" : "" %>
<li class="btn"><%= link_to "#{nav_link}".capitalize, "/#{nav_link}", id: "nav_main", class: "btn btn_nav #{add_class}" %></li>
<% end %>
</ul>
No Javascript necessary.
I'm inexperienced with middleman and ruby, but I've been trying to get Slate working so it generates a side navigation/list of header during build time instead of client side using javascript. The problem I am running into is getting the code to include the headers from partials.
An example of the directory structure:
Source
+--config.rb
+--includes
+--file.md
+--otherfile.md
+--index.html
+--layouts
+--layout.erb
Gist of layout and config.rb
Config.rb snippet for this:
require 'nokogiri'
helpers do
def toc_data(page_content)
html_doc = Nokogiri::HTML::DocumentFragment.parse(page_content)
# get a flat list of headers
headers = []
html_doc.css('h1, h2, h3').each do |header|
headers.push({
id: header.attribute('id').to_s,
content: header.content,
level: header.name[1].to_i,
children: []
})
end
[3,2].each do |header_level|
header_to_nest = nil
headers = headers.reject do |header|
if header[:level] == header_level
header_to_nest[:children].push header if header_to_nest
true
else
header_to_nest = header if header[:level] == (header_level - 1)
false
end
end
end
headers
end
end
Layout snippet for this:
<ul id="toc" class="toc">
<% toc_data(page_content).each do |h1| %>
<li>
<%= h1[:content] %>
<ul class="toc-section">
<% h1[:children].each do |h2| %>
<li>
<%= h2[:content] %>
<ul class="toc-submenu">
<% h2[:children].each do |h3| %>
<li>
<%= h3[:content] %>
</li>
<% end %>
</ul>
</li>
<% end %>
</ul>
</li>
<% end %>
</ul>
...
<div class="page-wrapper">
<div class="content">
<%= page_content %>
<% current_page.data.includes && current_page.data.includes.each do |include| %>
<%= partial "includes/#{include}" %>
<% end %>
</div>
</div>
Currently, only headers from the index.html file are getting populated and nothing from the included partials. I believe I may need the existing helper to occur post build similar to what is described in the Middleman docs for sitemaps using a ready helper. I believe I have to make another change to the config code so that it captures additional content outside of the page_content, but I'm not sure what that is due to lack of familiarity. Any pointers would be appreciated.
Edit: After looking into the middleman basics docs, there appear to be two helpers from the Padrino framework that I could make use of: capture_html and concat_content. I'm trying to find where the helper page_content is defined to get extra context for the specific changes I'm making.
Not familiar with that framework but looks like toc_data(page_content) only looks at the main content but not at the current_page.data.includes partials.
So guess you need to pass the partial to your toc_data function as well.
Maybe this works?
<%
full_content = page_content
current_page.data.includes && current_page.data.includes.each do |include|
full_content += partial("includes/#{include}")
end
toc_data(full_content).each do |h1|
%>
...
<% end %>
Hope that helps.
In order to concatenate the current page data with partials with the page_content, use the code below. This also changes what all is needed to yield a complete page.
<%
if current_page.data.includes
current_page.data.includes.each do |include|
page_content += partial("includes/#{include}")
end
end
%>
...
<%= page_content %>
I am creating a slider for my blog and I want to add a collection of featured items to it, The slider requires that the first child load with the class selected.
How can I do something like if first child do this else do that
Here is what I have so far:
<ul class="cd-hero-slider">
<% blog.articles.select {|a| a.data[:featured] }.each do |article| %>
<li class="selected" style="background-image: url('https://images.unsplash.com/photo-1447014421976-7fec21d26d86?ixlib=rb-0.3.5&q=80&fm=jpg&crop=entropy&s=c82e04e1201234889daab5427f481731')">
<div class="cd-full-width">
<h2><%= link_to article.title, article %></h2>
<p><%= article.summary(250) %></p>
<%= link_to 'Read More', article, :class => 'cd-btn' %>
</div>
</li>
<% end %>
</ul>
Use each_with_index instead of each - this will give you the object but also the position into the array, first being 0:
<% blog.articles.select {|a| a.data[:featured] }.each_with_index do |article, index| %>
<% if index == 0 %>
<li>I'm the first!</li>
<% else %>
<li>Not the first</li>
<% end %>
<% end %>
I have the following in one of my Layout files...
<% for link in #document.nextlink[0..0]: %>
<% if (link.name): %>
<ul class="actions">
<li><%- "#{link.helptext}" %></li>
</ul>
<% end %>
<% end %>
This works great. Unless, nextlink is not in my YAML at all. But that's what I want. Sometimes I want to have that button called Next and sometimes I do not.
if nextlink is not in my YAML, the DocPad compiler throws an error.
Any help would be much appreciated.
I am sorry for my bad english. I just try to description my question. :)
I have an application layout that have a yield for display post in body. I have another yield :footerpost3 for display title of recent post on the footer.
When I in localhost:3000, the yield :footerpost3 display a recent of title correctly. but when i am click a post link, which is the url is localhost:3000/posts/3, the yield :footerpost3 display nothing.
Here is my code:
app/views/layout/application.html.erb
<!-- begin footer comment widget -->
<div class="footer_list widget_recent_comments">
<div class="title"><h5>Artikel Terkini</h5></div>
<%= yield :footerpost3 %>
</div>
<!-- end footer comment widget -->
app/views/store/index.html.erb
<% content_for :footerpost3 do %>
<% #postsMain.each do |dopostAll| %>
<div class="entry">
<ul>
<li class="recentcomments"><%= link_to dopostAll.title, dopostAll %></li>
</ul>
</div>
<% end %>
<% end %>
i hope my question is easy to understand.. :)
Looks like your root url is stores#index .
You must be initializing #postsMain in the stores#index action and generating the content_for footerpost3 in stores/index.html.erb.
When you click on a post, you will be taken to posts#show page. So you have to initialize #postsMain even in posts#show action and generate the content for footerpost3 even in posts/show.html.erb
The answer is there in your question. You are defining the "content for" footerpost3 in that block, which exists in index.html.erb. When you're on /posts/3, index.html.erb is not rendered, but rather show.html.erb is.
To solve this, you'd need to add the content in the show.html.erb template as well.
You could solve this in multiple ways. Using nested layouts would be one. For example, you might create a posts layout at app/views/layout/posts.html.erb, like so:
<% content_for :footerpost3 do %>
<% #postsMain.each do |dopostAll| %>
<div class="entry">
<ul>
<li class="recentcomments"><%= link_to dopostAll.title, dopostAll %></li>
</ul>
</div>
<% end %>
<% end %>
<%= render :file => 'layouts/application' %>
In this way, all the views of your PostsController would use this layout, which simply adds your footer content, then renders the application_layout.
