Question

I am trying to create a spreadsheet on index page to display items with checkbox and if validated - the checkbox will be disabled so that people won't mis-ticked it.I was wondering should i do it with controller or the view? thanks : can you help?
In app/views/scooties_coupons/index.html.erb
<table class="table table-hover">
<h1>Scooties Coupons</h1>
<%= form_with(url: validate_coupons_path, method: 'patch') do |f| %>
<table>
<thead>
<tr>
<th>Valid</th>
<th>Coupon</th>
<th>Redeemed</th>
<th>First name</th>
<th>Surname</th>
<th>email</th>
<th>occupation</th>
<th>validation</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #scooties_coupons.each do |scooties_coupon| %>
<tr>
<td>
<%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
cf.check_box(:validated)
end %>
</td>
<td><%= scooties_coupon.coupon %></td>
<td><%= scooties_coupon.redeemed %></td>
<td><%= scooties_coupon.first_name %></td>
<td><%= scooties_coupon.surname %></td>
<td><%= scooties_coupon.email %></td>
<td><%= scooties_coupon.occupation %></td>
</tr>
<% end %>
</tbody>
</table>
<%= f.submit %>
<% end %>
<br>
</table>
in app/controllers/scotties_coupons_controller.rb:
def set_valid_coupons
to_valid = params[:scooties_coupons].select do |id, attrs|
attrs[:validated] == '1'
end
to_not_valid = params[:scooties_coupons].reject do |id, attrs|
attrs[:validated] == '1'
end
ScootiesCoupon.transaction do
ScootiesCoupon.where(id: to_valid.keys, validated: false).update_all(
validated:true)
ScootiesCoupon.where(id: to_not_valid.keys, validated: true).update_all(
validated:false)
end
redirect_to action: :index, notice: 'Validations updated'
end

you can do something like
<table class="table table-hover">
<h1>Scooties Coupons</h1>
<%= form_with(url: validate_coupons_path, method: 'patch') do |f| %>
<table>
<thead>
<tr>
<th>Valid</th>
<th>Coupon</th>
<th>Redeemed</th>
<th>First name</th>
<th>Surname</th>
<th>email</th>
<th>occupation</th>
<th>validation</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #scooties_coupons.each do |scooties_coupon| %>
<tr>
<td>
<% if true %>
SOMETHING HERE
<% else %>
<%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
cf.check_box(:validated)
end %>
<% end %>
</td>
<td><%= scooties_coupon.coupon %></td>
<td><%= scooties_coupon.redeemed %></td>
<td><%= scooties_coupon.first_name %></td>
<td><%= scooties_coupon.surname %></td>
<td><%= scooties_coupon.email %></td>
<td><%= scooties_coupon.occupation %></td>
</tr>
<% end %>
</tbody>
</table>
<%= f.submit %>
<% end %>
<br>
</table>
