form not updating for specific record rails - ruby-on-rails

Question

I'm trying to update a record with a button, by having and admin user tyoe confirm a record by clicking the confirm submit button with this form, but it would just update the first record in the database, not the specific one. Can i put "hour.id" in the form_for section to make it update the record i want it to?
index.html.erb form view
<% #allhours.each do |hour| %>
<tr id="dashfield">
<td><%= hour.user.first_name + " " +hour.user.last_name %></td>
<td><%= hour.assignment %></td>
<td><%= hour.hours %></td>
<td><%= hour.supervisor %></td>
<td><%= hour.date %></td>
<td><%= link_to "confirm", edit_hour_path(hour.id, :status => 'confirmed')%></td>
</tr>
<% end %>
Controller
def index
#allhours = HourLog.where(status:'pending')
end
def update
#hour = HourLog.find_by(status:'pending')
#hour.update_attribute(update_hour_params)
redirect_to '/dashboard/hours'
end
def edit
#hour = HourLog.find(params[:id])
#hour.update_attributes(update_hour_params)
redirect_to '/dashboard/hours'
end
hour_log model
class HourLog < ActiveRecord::Base
belongs_to :user
end
routes
Rails.application.routes.draw do
root 'welcome#index'
get '/signup' => 'users#new'
resources :users
get '/dashboard/users' => 'users#index'
put '/dashboard/users' => 'users#update'
get '/login' => 'sessions#new'
post '/login' => 'sessions#create'
delete '/logout' => 'sessions#destroy'
get '/dashboard' => 'hours#new'
get '/dashboard/hours' => 'hours#index'
put '/dashboard/hours' => 'hours#update'
resources :hours
Thanks!

This line :
#hour = HourLog.find_by(status:'pending')
will find the first Hourlog that is in pending status. You should pass the hourlog id in the form and use it in the controller
change the line in the routes :
put '/dashboard/hours/:id' => 'hours#update'
in the view :
<%= form_tag dashboard_hours_path(id:hour.id), method: :put do %>
<%= hidden_field_tag :role, :value => 'confirm'%>
<%= submit_tag 'Confirm'%>
<% end %>
in the controller :
#hour = HourLog.find(params[:id])
