Rails: How to get one model to "belong" to another model? - ruby-on-rails

Question

I have a model "votes" which belongs_to two models by polymorphous association, and has the attributes user_id and comment_id. Previously, I had a voting system in place for users that would create a new vote for a specific user every time a button was pressed:
<%= form_for [#user, #vote] do |f| %>
<input type="hidden" id="user_id" name="user_id" value="#{#user.id}" />
<%= f.submit ": )", :onclick => 'alert("Voted up!")' %>
<% end %>
and #user.votes.count would return the number of times the button was pressed. However, I switched to a different method:
View:
<%= link_to "voteuser", vote_user_path(#user.id), method: :post, :class => "btn btn-small" %>
Controller:
def vote
#user = User.find(params[:id])
Vote.create!(user_id: #user.id)
redirect_to #user
end
Routes:
Website::Application.routes.draw do
root 'home_page#home'
get "votes/new"
get 'users/random'
post 'users/vote/:id' => 'users#vote', as: 'vote_user'
get 'users/users/random' => 'users#random'
resources :users
get "all/allusers"
get "all/users/new" => 'users#new'
get 'all/all/allusers' => 'all#allusers'
end
and a Vote is still created, with a user_id equal to the current User.id, but now #user.votes.count returns 0, so the application isn't registering that the vote belongs to the user. How can I remedy this?
Vote Model:
class Vote < ActiveRecord::Base
belongs_to :voteable, polymorphic: true
end
Votes Schema:
create_table "votes", force: true do |t|
t.integer "thing_id"
t.integer "comment_id"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "voteable_id"
t.string "voteable_type"
end
User Model:
class User < ActiveRecord::Base
has_many :votes, as: :voteable
end
User Schema:
create_table "users", force: true do |t|
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
t.string "avatar_file_name"
t.string "avatar_content_type"
t.integer "avatar_file_size"
t.datetime "avatar_updated_at"
end

Answer 1

It should be Vote.create!(voteable_id: params[:id], voteable_type: 'User') for users or in short
Vote.create!(vote: User.find(params[:id])) # Vote.create!(vote: Comment.find(params[:id]))

Answer 2

check if you retrieve the user id in your controller and you can in your view
<%= form_for [#user, #vote] do |f| %>
<%= f.hidden_field :user_id, value: f.model.user.id %>
<%= f.submit ": )", :onclick => 'alert("Voted up!")' %>
<% end %>
on your controller you can simply do:
def vote
Vote.create!(user_id: params[:id])
redirect_to #user
end
but you use the polymorphous association so you have to specify the user_id and the user_type.
