javascript - load bootstrap modal on redirect -

-

i have bootstrap modal allows users sign in. want users have not authenticated have sign modal pop on whatever page at.

session controller

  def new     respond_to |format|       format.html       format.js     end   end

session/new.js.erb

$("#modal-window").html("<%= escape_javascript(render 'sessions/new') %>");

if user hit controller want them see signin modal. figured try redirect them new_session_path. didn't work , got missing template error.

  def new     if current_user       @image = image.new     else       redirect_to new_session_path     end   end

if send html request, should html back. rails looking html template , isn't finding one.

i recommend using before_action controllers or actions want restrict. require making html template sign in.

before_action :verify_user, only: [:new]  def verify_user   redirect_to new_session_path , return unless current_user end

(or redirect_to root_path or somewhere , trigger modal on page load.)

as modal, listen clicks on links want restrict.

# users.js.coffee $ ->   $('body.not-signed-in a.require-sign-in').click, ->     $.get $('body').data('sign-in-path')     return false

which means you'd have add classes in html.

<body class="<%= current_user ? 'signed-in' : 'not-signed-in' %>" data-sign-in-path="<%= new_session_path %>">   <%= link_to 'link', some_path, class: 'require-sign-in' %>

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
