ruby on rails - Using partial with paper trail -


i'm trying put code in partial show page in /events. code works fine when use in show page, when extract partial i'm getting no method error

undefined method `event' #<activerecord::associations::collectionproxy::activerecord_associations_collectionproxy_papertrail_version:0x007f4368823a68>

versions/_version.html.erb

<% cache version %>   <div class="feed-item">     <h4>       <%= link_to version.item.name, version.item %>        <small>       <%= version.event + "d" %> <%= link_to user.find(version.whodunnit).username, user.find(version.whodunnit) %>       </small>     </h4>      <ul class="list-unstyled">       <% version.changeset.each |data| %>         <li>           <strong><%= data[0].capitalize %>:</strong>            <% if data[1][0].present? %><p class="red">- <%= data[1][0] %></p><% end %>             <p class="green">+ <%= data[1][1] %></p>         </li>       <% end %>     </ul>   </div> <% end %>

show.html.erb

<%= render :partial => '/versions/version', :object => @versions %>

events controller

  def show     @versions = @event.versions   end

events model

has_paper_trail

any idea how put code in partial instead of having inside show view? thanks.

edit: still no method error

undefined method `item' #<activerecord::associations::collectionproxy::activerecord_associations_collectionproxy_papertrail_version:0x007f43688ee1a0>

events_controller.rb

before_action :set_event, only: [:show, :update, :destroy]  def set_event   @event = event.find(params[:id]) end

do have defined @eventvariable in eventscontroller? @event.versions method has called on actual event object.

for example

def show   @event = event.find(1)   @versions = @event.versions end

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
