how display specific data from db in rails?

Question

I have two Model user and speed

User Model contain

name,email,password,id_watch all this get from sign up In addition to user_id

speed Model contain

id_watch,x_speed,y_speed all this already add by watch device

need when user sign up then enter id_watch get all id_watch data

when id_watch from user table equal id_watch from speed table

Speed.where(id_watch: current_user.id_watch) nor use .find if want to return just one id_watch — 7urkm3n

if speed model is just public data and want to make sure user interest == to public data then no need. It all depends how modeling an application. — 7urkm3n

You can create smth like this. Association is not important for this.

#view pages
<% @speed_data.each do |sd| %>
   <%= "#{sd.x_speed} : #{sd.y_speed}" %>
<% end %>

#in controller where using current_user or user object
#sample
def index
   @speed_data = current_user.speed_data
end

# models/user.rb
class User < ApplicationRecord
   def speed_data
      Speed.where(id_watch: self.id_watch)
   end
end

# models/speed.rb
class Speed < ApplicationRecord
end
