ActiveRecord::RecordNotFound Couldn't find User without an ID

I made a simple voting system for users

votes_controller:

def create
  @user = User.find(params[:id])
  @vote = Vote.create(author_uid: current_user.uid)
  @user.votes << @vote

  redirect_to root_url
end

view file:

- @users.each do |user|
  %tr
    %td= user.id
    %td= link_to user.username, user.url
    %td
      = link_to 'Like', {:controller => "votes", :action => "create" }, :method => "post"

But if I vote for user there is an error "Couldn't find User without an ID"

Hope you will help to solve this problem. If you need more information, please comment.

Thanks!

Change 

link_to 'Like', {:controller => "votes", :action => "create" }, :method => "post"

to

link_to 'Like', {:controller => "votes", :action => "create", :id => user.id }, :method => "post"

Also, you're not saving your user object after creating the votes object.

You are not passing in an id param in your link_to method.

That is why the params[:id] doesnt exist when you try to look it up on the server
