How Do I save it to the database?

Question

I'am Making a form which has checkboxes with values true or false.

<%= form_tag url_for(action: 'create'), method: "post" do %>
<tbody>
  <tr>
  <td class="image"> <%= image_tag("https://cdn.iris.nitk.ac.in/images/new_dashboard/button_Human.png", class: 'list_image') %></td>
  <td>Profile</td>
  <td><%= check_box_tag '1', true, true, :checked => true, data: {toggle: "toggle", on: "Yes", off: "No", onstyle: "success", offstyle: "danger"} %></td>
  </tr>
  <tr>
  <td class="image"> <%= image_tag("https://cdn.iris.nitk.ac.in/images/new_dashboard/withdraw.png", class: 'list_image') %></td>
  <td>Withdraw Admission</td>
  <td><%= check_box_tag '2', true, true, :checked => true, data: {toggle: "toggle", on: "Yes", off: "No", onstyle: "success", offstyle: "danger"} %></td>
  </tr>
  <tr>
  <td class="image"> <%= image_tag("https://cdn.iris.nitk.ac.in/images/new_dashboard/button_academics.png", class: 'list_image') %></td>
  <td>Course Registration</td>
  <td><%= check_box_tag '3', true, true, :checked => true, data: {toggle: "toggle", on: "Yes", off: "No", onstyle: "success", offstyle: "danger"} %></td>
  </tr>
</tbody>

"btn btn-primary btn-lg btn-block %>

upon submitting it takes me to this create action in controller.

def create
1.upto(13) do |i|
  (params[:i] ? (current_user.misc_data[:pin_modules] ||= []) << i : next)
end
redirect_to '/'

end end

where pin_modules is an array that i want to create inside user model's misc_data hash. i don't get any error while submitting but when i check db there's no array and nothing is saved. Can anyone please help me out?

You're updating the objects attributes but as you say not saving them to the DB. Try:

def create
  current_user.misc_data[:pun_modules] ||= []

  (1..13).each do |i|
    next unless params[:i]
    current_user.misc_data[:pin_modules] << i
  end

  current_user.save
  redirect_to '/'
end

Or if you wanted to keep your ternary, just add a current_user.save before you redirect
