I currently have 3 loops im in my _header I have
if current_user.admin? && !current_user?(user)
Also
<% if logged_in? %>
And
<% else %>
It all works fine with no error if i take out
<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
</end>
When I paste it back in i get the error. I dont know whats wrong with this syntax.
Can anyone help?

You're not properly closing the if you pasted :
<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
</end>
You should try to replace that by :
<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
<% end %>
structure of if loop in ruby.your end tag of if loop is incorrect.see below
<%if%>
//condition here
<%end%>
can you try this out:
<% if logged_in? && !current_user?(user) && current_user.admin? %>
<li><%= link_to "Admin", users_path %></li>
</end>
Syntex error in closing of if block syntex.
1 <% if current_user.admin? && !current_user?(user) %>
2 <li><%= link_to "Admin", users_path %></li>
3 </end>
Error at line 3, replace line 3 ie </end> with <% end %>

I am trying to refactor some of the code in my view
<% if controller.controller_name == "overview" %>
<div id="left-menu">
<ul>
<li>Office</li>
<hr>
<li><%= link_to "Overview", root_path %></li>
<li><%= link_to "Personnel", personnel_path %></li>
<li><%= link_to "Results", results_path %></li>
<li><%= link_to "Statistics", statistics_path %></li>
</ul>
<ul>
<li>Economy</li>
<hr>
<li>Finances</li>
<li>Contracts</li>
<li>Transfers</li>
<li>Sponsors</li>
</ul>
</div>
<% elsif controller.controller_name == "market" %>
<div id="left-menu">
<ul>
<li>Items</li>
<hr>
<li><%= link_to "Engines", market_engines_path %></li>
<li><%= link_to "Weapons", market_weapons_path %></li>
<li><%= link_to "Armor", market_armor_path %></li>
<li><%= link_to "Chips", market_chips_path %></li>
</ul>
<ul>
<li>Personnel</li>
<hr>
<li><%= link_to "Drivers", market_drivers_path %></li>
<li><%= link_to "Servicemen" %></li>
<li><%= link_to "Programmers" %></li>
<li><%= link_to "Managers" %></li>
</ul>
</div>
<% end %>
Where each <li> corresponds to a method in the controller. I would like to be able to add new methods to my controllers, and then have them dynamically inserted in the view. So is there a way to iterate over the methods in a controller?
As per the answer provided in the referenced question, Controller.action_methods seems to be the method you need, however, to integrate into your code is as follows:
<% lists = %w(items personell) %>
<% for list in lists do %>
<ul>
<li><%= list.titleize %></li>
<hr>
<% items = MarketsController.action_methods %>
<% for item in items do %>
<li><%= link_to item.titleize, eval("market_#{item}_path") %></li>
<% end %>
</ul>
<% end %>
My question assumes a specific answer but it may not but accurate.
I've created a route:
get 'users/:id/groups/' => 'users#groups', as: "my_groups"
but when I go to access this path, conditionally, in a view, i get an exception:
ActionController::UrlGenerationError at /
No route matches {:controller=>"users", :action=>"groups"} missing required keys: [:id]
Here is the partial with the offending line:
<% if user_signed_in? %>
<li id="groups-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Groups <b class="caret"></b>
</a>
<ul class="dropdown-menu">
#offending line:
<li><%= link_to 'My Groups', my_groups_path %></li>
<li><%= link_to 'Create a Group', new_group_path %></li>
</ul>
</li>
<li><%= link_to 'Logout', destroy_user_session_path, :method=>'delete' %></li>
<% else %>
<li><%= link_to 'Login', new_user_session_path %></li>
<% end %>
<% if user_signed_in? %>
<li><%= link_to 'Edit account', edit_user_registration_path %></li>
<% end %>
<% if user_signed_in? %>
<% if current_user.has_role? :admin %>
<li><%= link_to 'Admin', users_path %></li>
<% end %>
<% end %>
it seems that there is no current_user set, perhaps?
It's unclear how this could break if the user_signed_in? method is working.
You need to pass in the :id parameter to the url helper function
<li><%= link_to 'My Groups', my_groups_path(current_user) %></li>
The code below works as it should, but after adding a dropdown navigation with some embedded ruby, I get a no method error.
NoMethodError in Static_pages#home

My _header.html.erb which gives no errors
<header class="navbar navbar-fixed-top navbar-inverse">

<li><%= link_to "Log in", signin_path %></li>
</ul>
</nav>
</div>

</header>
This is the _header.html.erb with the code I added. Which gives me the error.

It's telling you that there is a problem with your signed_in? method.
That's where you need to start checking.
Hope this helps
I want to be able to replace Accounts tab on my navigation bar with the User's name when they logged in. How would i go about doing that. Would i have to use some sort of embedded ruby like <%= #user.name %>
heres the html
enter code here
<header class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<%= link_to "sample app", root_path, id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li>
<% if signed_in? %>
<li><%= link_to "Users", '#' %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account
<b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><%= link_to "Profile", user_path(current_user) %></li>
<li><%= link_to "Settings", '#' %></li>
<li class="divider"></li>
<li>
<%= link_to "Sign out", signout_path, method: 'delete' %>

</li>
<% else %>
<li><%= link_to "Sign in", signin_path %></li>
<% end %>
</ul>
</nav>
</div>
</div>
</header>
Try:
<%= current_user.name %>
I am following the ruby on rails tutorials from http://ruby.railstutorial.org .
The following is the _header.html.erb code, is the same as the tutorials. but the drop down function of account does not work.
<header class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<%= link_to "sample app", root_path, id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li>
<% if signed_in? %>
<li><%= link_to "Users", users_path %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account <b class="caret"></b>

Without seeing more of the application it's hard to determine the exact problem, however based on what you have supplied I can suggest the following:
refer to http://twitter.github.com/bootstrap/javascript.html#dropdowns and ensure you are using the right markup nesting (looks like you are)
make sure you have included the javascript files within your application.js file (your manifest file). The docs for bootstrap here: http://twitter.github.com/bootstrap/components.html#navbar say that you need to have the dropdown JS file included to make the dropdown work properly.
Please let me know if any of this helps.
