ruby - Friendship Status Detection - Rails 5 -


i'm creating social network ruby on rails , want display following link if users are:

not friends display "not friends" friends display "friends" pending request display "pending"

but i'm getting "uninitialized constant owner::friendship" error on friendship = friendship.where(owner_id: [self.id,owner_2.id], friend_id: [self.id,owner_2.id])

owner.rb

    has_many :follows, dependent: :destroy   has_many :inverse_follows, class_name: "follow", foreign_key: "friend_id",    dependent: :destroy    def request_friendship(owner_2)     self.friendships.create(friend: owners_2)   end    def pending_friend_requests_from     self.inverse_friendships.where(state: "pending")   end     def pending_friend_requests_to     self.friendships.where(state: "pending")   end    def active_friends     self.friendships.where(state: "active").map(&:friend) + self.inverse_friendships.where(state: "active").map(&:owner)   end    def friendship_status(owner_2)         friendship = friendship.where(owner_id: [self.id,owner_2.id], friend_id: [self.id,owner_2.id])         unless friendship.any?           return "not_friends"         else           if friendship.first.state == "active"             return "friends"           else             if friendship.first.owner == self               return "pending"             else               return "requested"             end           end         end     end  end

owners_helper.rb

module ownershelper     def action_buttons(owner)         case current_owner.friendship_status(owner) when "friends"             "remove friendship"         when "pending"             "cancel request"         when "requested"             "accept or deny"         when "not_friends"             "add friend"         end     end end

_owner.html.erb

<h3> <small><%= owner.username %></small><br> <%= owner.fullname %>`</h3>  <p>     <%= owner.businessname %> </p>  <% if current_owner %>     <%= action_buttons(owner)%> <% end %>

follow.rb

    class follow < applicationrecord     belongs_to :owner     belongs_to :friend, class_name: "owner" end

friendship_controller.er

    class friendshipscontroller < applicationcontroller     before_action :authenticate_owner!     before_action :set_owner, only: [:create]       def create         @friendship = current_owner.request_friendship(@owner)         respond_to |format|             format.html {redirect_to owners_path, notice: "friendship created"}         end     end      def destroy         @friendship.destroy         respond_to |format|             format.html {redirect_to owners_path, notice: "friendship deleted"}         end     end      private      def set_owner         @owner = owner.find(params[:owner_id])     end end

as mentioned on comments, error happened because there no friendship class. there 2 solutions resolve:

1) change friendship references follow.

2) rename follow class -> friendship

  class friendship < activerecord::base     self.table_name = "follows"      ...   end

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

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
