ruby on rails - link_to tag is being called with my project - 


<div class="container-fluid" id="manage"> <h2>managing users</h2>  <table>     <tr>         <td></td>         <td><%= link_to "add user", users_new_path, method: :get, class: "btn btn-primary" %> <br />  <!--  go add-user-page  --></td>     </tr>     <tr>         <td><button class="btn btn-danger navbar-btn"> emails</button><br /></td>         <td><button class="btn btn-danger navbar-btn"> delete</button><br /></td>     </tr>      <% @users.each |user| %>       <tr>         <td><button class="btn btn-info"><%= user.email %></button></td>         <td><%= link_to "del", users_delete_path(id: user.id), method: :delete ,class: "btn btn-info", data: { confirm: "you sure?" }%></td>       </tr>      <% end %>  </table>   </div>

in file, delete action , new action called twice. tried according stack answers( link_to :confirm displays popup twice why ruby on rails link_to sending action twice?. , etc)

who can me?

edited - application.js

//= require jquery //= require bootstrap-sprockets //= require jquery_ujs //= require rails-ujs //= require turbolinks //= require_tree .

the simplest solution remove //require rails-ujs line. 

//= require jquery //= require bootstrap-sprockets //= require jquery_ujs //= require turbolinks //= require_tree .

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
