I'm trying to render the following partial:
<% content_for :admin_content do %>
<h3>Listing All Accounts</h3>
<%= paginate (@accounts) %>
<table id="indexTable" class="table table-striped">
...
</table>
<%= paginate (@accounts) %>
<br>
<%= link_to 'New Account', new_account_path %>
<% end %>
(there are other similar partials as well)
... in the following layout:
<!DOCTYPE html>
<html>
<head>
...
</head>
<body>
<%= render 'navigation' %>
<% if notice %>
<p class="alert alert-success"><%= notice %></p>
<% end %>
<% if alert %>
<p class="alert alert-danger"><%= alert %></p>
<% end %>
<main>
<%= render partial: 'admin_navigation' %>
<%= yield :admin_content %>
</main>
<footer>
...
</footer>
</body>
</html>
The reason I'm trying to use content_for is that I have a couple of other pages similar to the above partial that I want to render when a link is clicked in the navigation:
<div id="panel">
<div class="navbar subnav navbar-inverse admin-nav" role="navigation">
<div class="navbar-inner">
<div class="container-fluid">
<h2>Admin Dashboard</h2>
<ul class="pager subnav-pager">
<div class="btn-group btn-group-justified" role="group" aria-label="navigation">
<span role=button><%= link_to "Manage Accounts", {:action=>"manage_accounts"}, :class => "btn btn-primary" %></span>
<span role=button><%= link_to "Manage Customers", {:action=>"manage_customers"}, :class => "btn btn-primary" %></span>
<span role=button><%= link_to "Manage Transactions", {:action=>"manage_acct_transactions"}, :class => "btn btn-primary" %></span>
</div>
</ul>
</div>
</div>
</nav>
</div>
The above links call respective methods in the controller, which are as follows:
def manage_accounts
@accounts = Account.order('id').page(params[:page]).per(15)
render partial: 'manage_accounts'
end
def manage_customers
@customers = Customer.order('lastname').page(params[:page]).per(15)
render partial: 'manage_customers'
end
def manage_acct_transactions
@acct_transactions = AcctTransaction.order('date DESC').page(params[:page]).per(15)
render partial: 'manage_acct_transactions'
end
But when you click the links in navigation, it just shows a blank page with no html at all. The console says that the objects are loaded as per the controller, and that the partial is being rendered. But where is it?
I've tried all kinds of ways to get this to work. The closest I got was actually without the content_for/yield and just calling the method, which of course rendered the partial as if it were its own page (bad). There used to be something called replace_html which would probably work for what I'm trying to do but I'm using Rails 4.1.8.
Initially, I set this navigation up with AJAX, but it just doesn't work here. These partials have links for CRUD actions as well as redirects. Using AJAX led to all kinds of CSRF errors and seems like it adds an unnecessary layer of complexity for something that should be pretty simple.
Why does the above code not render anything?
Am I taking the wrong approach?
Thanks
EDIT: adding logs for the page request..

Also, here is the routes.rb if that helps solve this problem..
Rails.application.routes.draw do
devise_for :users, :controllers => { :registrations => "registrations" }
devise_scope :user do
post "/accounts/adminview" => "devise/sessions#new"
end
root 'home#index'
get 'home/about'
get 'home/help'
get 'accounts/add_account', to: 'accounts#new'
post 'accounts/add_account', to: 'accounts#create'
resources :administrators do
member do
get :adminview
get :manage_accounts
get :manage_customers
get :manage_acct_transactions
end
end
resources :users do
resource :customers
resource :accounts
resource :addresses
end
resources :accounts do
resource :acct_transactions
end
resources :account_types, :accounts, :addresses, :administrators, :customers, :transaction_types, :acct_transactions, :users
end
Again, according to logs, it supposedly is loading the partial _manage_accounts, but I'm only seeing a blank page. I've tried using path helper but it throws a "Missing Template" error. Have tried lots of other things, instead of the action method but I still get the same result.
Why are you rendering partials as the views for your actions?
def manage_accounts
@accounts = Account.order('id').page(params[:page]).per(15)
render partial: 'manage_accounts'
end
Calling render partial like this will only render the content of the partial and will not load the layout. If you want the layout (and it certainly sounds like you do) then rename this file to a normal view app/views/administrators/manage_accounts.html.erb and then remove the render call from your action altogether.
I would also advise splitting each of these manage routes out into their own controllers, so instead you would have app/views/admin/accounts/index.html.erb, which would become the new view to manage accounts. I suggest this because it falls in line with the more traditional CRUD design of a Rails application.
