user - rails tutorial: cookie doesn't match remember token -


i doing michael hartl's rails tutorial chapter 8. when try find user remember_token stored in browser cookie isn't working. find_by method returns nil. have been trying debug looking @ remember token cookie stored on browser , comparing remember token stored in user database. don't match , don't know why. here code session helper.

module sessionshelper    def sign_in(user)     remember_token = user.new_remember_token     cookies.permanent[:remember_token] = remember_token     user.update_attribute(:remember_token, user.encrypt(remember_token))     self.current_user = user   end    def signed_in?     !current_user.nil?   end    def current_user=(user)     @current_user = user   end    def current_user     #remember_token = user.encrypt(cookies[:remember_token])     remember_token = "71e45660fbaa69bad9fb55b912f80122a584f6af"     #@current_user ||= user.find_by(remember_token: remember_token)     @current_user ||= user.find_by_remember_token(remember_token)    end  end

i have been tweaking try , figure out going on. debug commented out normal lines , set remember token explicitly value see in database - app works. when compare value of cookie stored in browser value of remember token stored in database don't match.

another thing noticed can't make call user_find_by. error says doesn't recognize method commented out. can call user.find_by_remember_token. possible have wrong version of installed?

i have tried resetting database - can see , looks has right columns.

here _header.html.erb code:

<header class="navbar navbar-fixed-top navbar-inverse">   <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", current_user %></li>                 <li><%= link_to "settings", '#' %></li>                 <li class="divider"></li>                 <li>                   <%= link_to "sign out", signout_path, method: "delete" %>                 </li>               </ul>             </li>           <% else %>             <li><%= link_to "sign in", signin_path %></li>           <% end %>         </ul>       </nav>     </div>   </div> </header>

it looks problem line 20 in sessionshelper. should be:

@current_user ||= user.find_by(remember_token: remember_token)

instead of passing remember token user.find_by() method you're attempting call method find_by_remember_token, doesn't exist.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
