I have a list of tabs at the top of my application that I include in a general layout in application.html.erb. They look like this:
<li class="current"><%= link_to "Home", provider_path(current_user.id), :method=> "GET"%> </li>
<li><%= link_to "Edit Profile", edit_student_path(current_user.id) %> </li>
<li><%= link_to "Search", provider_search_path %> </li>
I want to change the selected tab to the "current" one, when I hit that page. So when I click Edit Profile and the Edit Profile page loads, the tabs should appear as follows:
<li><%= link_to "Home", provider_path(current_user.id), :method=> "GET"%> </li>
<li class="current"><%= link_to "Edit Profile", edit_student_path(current_user.id) %> </li>
<li><%= link_to "Search", provider_search_path %> </li>
Is there a way to do this outside of adding javascript to the page which is displayed? Or if there is what is generally best practice for doing this in the DRYest way possible.
Thanks
You can use controller.class == and controller.action_name == to figure out exactly which controller and action you are on
so it would be something like
<li class="<%= controller.class == ProviderController and controller.action_name == 'show' ? 'current' : '' %>"><%= link_to "Home", provider_path(current_user.id), :method=> "GET"%> </li>
<li class="<%= controller.class == StudentController and controller.action_name == 'edit' ? 'current' : '' %>"><%= link_to "Edit Profile", edit_student_path(current_user.id) %> </li>
<li class="<%= controller.class == ProviderController and controller.action_name == 'search' ? 'current' : '' %>"><%= link_to "Search", provider_search_path %> </li>
I believe there are some ways to get the current url for the page you are on, but then your "active" styling will be dependent on only getting to that action via that path, which may not always be the case depending on the routes, this way will ensure the view shows what is true based on what was actually run, not what the url is in the address bar
You could try something like:
<li class="<%= controller.controller_path == 'provider' ? 'current' : '' %>"><%= link_to "Home", provider_path(current_user.id), :method=> "GET"%> </li>
<li class="<%= controller.controller_path == 'student' ? 'current' : '' %>"><%= link_to "Edit Profile", edit_student_path(current_user.id) %> </li>
<li class="<%= controller.controller_path == 'search' ? 'current' : '' %>"><%= link_to "Search", provider_search_path %> </li>
...and just check which controller you're coming from.
Take a look at TabsOnRails
You could just do this:
<%= current_page?(:controller => 'your_controller', :action => 'index') ? 'current' : '' %>
I made a helper for this that can accept any number of arguments which is useful for nested resources, but it also accepts a single controller name just like the other answers.
application-helper.rb:
def is_active(*links)
links.each { |link| return "active" if params[:controller] == link }
end
application.html.erb:
<li class="<%=is_active('home')%>">...</li>
Or
Example usage with HAML & nested resource(will be active for any of the provided controller names):
applcation.html.haml:
%li{:class => is_active('blogs', 'comments')}
When you switch pages you could pass something like #current_tab back to the erb from the controller methods. Then use #current_tab to decide which li should be the current class. Alternatively, you could give each li and id or some unique attribute and simply change the class with your JavaScript framework of choice.
I'm so not claiming this is the best way to do this, however I am brave enough to post what I came up with :)
Some example menu links from my layout:
<li class="nav-calendar"><%= menu_link_to 'teachers', 'show_date', 'Calendar', calendar_url %></li>
<li class="nav-announcements"><%= menu_link_to 'announcements', nil, 'Announcements', announcements_path %></li>
Then I created this helper:
def menu_link_to(*args, &block)
controller = args.shift
action = args.shift
if controller == controller_name && (action.nil? || action == action_name)
if args.third.nil?
args.push({:class => 'selected'})
else
args.third.merge!({:class => 'selected'})
end
end
link_to *args, &block
end
I did this in the application helper and it seems to work fine:
def current_page(path)
"active" if current_page?(path)
end
Then call like this:
<li class="<%= current_page(root_path)%>"> <%= link_to "Home", root_path %></li>

I'm trying to create a navbar that highlights the li item on which page I am.
In my code below I'm trying to use a conditional operator to see if the current path is correct. Or at least that's what I think i'm doing.
<li id="home-link" data-hook class="<%= root_path ? "active" : "" %>"><%= link_to Spree.t(:Home), spree.root_path %></li>
<% if spree_current_user %>
<li id="home-link" data-hook class="<%= products_path ? "active" : "" %>" ><%= link_to Spree.t(:products), spree.products_path %></li>
<% end %>
What I then expect to happen is that if i'm on the home page the li get's the class active,
what currently happens is that all li items get the class active.
How can I check the current path?
No, you are testing if the path helpers are true, and they are as they return a String. That's why active is always set.
Take a look at current_page?:
<% product_active = 'active' if current_page?(controller: 'products', action: 'index') %>
<li id="home-link" data-hook class="<%= product_active %>">
EDIT: As #NensiMakawana suggets, you can alternatively use the active_link_to gem.
I'm using rails 4. and i'm trying to achieve links to be active as long as "main" url checked.
All i want to do is:
<li class="<%= 'active' if current_page?(events_path) %>"><%= link_to "Events", events_path %></li>
<li class="<%= 'active' if current_page?(contact_path) %>"><%= link_to "Contact us", contact_path %></li>
"Events" or "Contact us" links will be active as long as they are matching:
mydomain.com/events
mydomain.com/events/event-1
mydomain.com/events/event-1/job and etc.
How can i achieve that?
By the way I'm passing :id of events and i can't check if it's the current page, because sometimes i'm not passing the param.
You can use params[:controller] and params[:action] to check where you are.
It goes something like this :
<li class="<%= 'active' if params[:controller]=="events" and params[:action] == "index" %>"><%= link_to "Events", events_path %></li>
Of course you may need to tweak it to your precise needs.
Following a previous post I (almost) successfully implemented highlighted navigation using CSS and Rails.
<ul class="nav">
<li class="<%= "active" if params[:controller] == "sweets" %>"><%= link_to 'Sweets', sweets_path %> </li>
<li class="<%= "active" if params[:controller] == "sweets/new" %>"><%= link_to 'New Sweets', new_sweets_path %> </li>
<li class="<%= "active" if params[:controller] == "tasks" %>"><%= link_to 'Tasks', tasks_path %> </li>'Customers', customers_path %> </li>
<li class="<%= "active" if params[:controller] == "suppliers" %>"><%= link_to 'Suppliers', suppliers_path %> </li>
</ul>
The only issue is that one of my navigational items is for creating a new item rather than being to an entirely different page. I have tried the above using /new on the end of the normal controller text but it hasn't worked.
Is this method possible when navigating to the method pages or do I need to implement it in a different way? Sorry if this is a repeat question but I couldn't find anyone with the same situation.
Thanks in advance and any hints or tips are always welcome.
You can check for action as well:
if params[:action] == 'some_action'
I am trying to set an li class of active based on what page the user is on.
I have 4 navigation elements and they all look something like this:
<% if #activeLi == "home" %>
<li class="active">
<% else %>
<li>
<% end %>
<%= link_to :controller => "home" do %>
<span>Home</span>
<% end %>
</li>
and then in each controller I just set #activeLi like this:
def index
#activeLi = "about"
end
I know this is pretty basic stuff, but i'm just wondering if there is an easier way to do this?
Well I know one way you can simplify this and thats by getting rid of the need to use those nasty instance variables.
<li class="<%= controller_name == "home" ? 'active': '' %>">
<%= link_to :controller => "home" do %>
<span>Home</span>
<% end %>
</li>
I have a rails app using a ul as a toolbar. I want to have a style (selected) to apply to the page the user is on.
How can I do that?
This is what I have so far, but the selected style is hard coded and I'm also not sure how to know what page is selected.
<ul>
<li class="firstItem"><%= link_to "About", '/about' %></li>
<li class="item"><%= link_to "Page1", '/page1' %></li>
<li class="item selected" <%= link_to "Page2", '/page2' %></li>
<li class="item"><%= link_to "Contact", '/contact' %></li>
<li class="lastItem"><%= link_to "Blog", '/blog' %></li>
</ul>
I agree totally with Jarrod's advice, but just in case you encounter the need to process additional conditions (and want to avoid ugly embedded ruby in your HTML code), take a look at Rails' content_tag method.
With it, you can replace something like:
<li class=<%= #post.active? ? 'active' : 'suspended' %>>
<%= link_to #post.name, post_path(#post) %>
</li>
With something like:
<%= content_tag :li, link_to(#post.name, post_path(#post), :class => #post.active? ? 'active' : 'suspended' %>
And of course, sticking this code into a helper and calling it from there will earn you more elegance-points.
Hope this helps.
PS: This is my first post on Stackoverflow, please be gentle. :)
if each li is linked to different controller you can use controller_name to add or not the selected class
Here is an example from my app, it's in haml
%ul
%li
%a{:href => '/kebabs', :class => ('current' if controller_name == 'kebabs')} Admin kebabs
%li
%a{:href => '/statistics', :class => ('current' if controller_name == 'statistics')} Statistiques
%li
%a{:href => '/people', :class => ('current' if controller_name == 'people')} Admin Personnes
cheers
You can also use css for this. Give each the body each page a class and id from your controller and action names.
<body class="<%= controller.controller_name %>" id="<%= controller.action_name %>">
Then give your ul and li elements an id.
<ul id="nav'>
<li id="about"></li>
<li id="contact"></li>
<li id="blog"></li>
</ul>
Now you can reference a specific link on a specific page from your stylesheet.
body.blog#index ul#nav a#blog:link
So if you want to make section links 'sticky' you can reference them all at once, leaving out the body id.
body.blog ul#nav a#blog:link,
body.contact ul#nav a#contact:link {
background-color: red;
}
