I have developed the sign,sign_up and log_out using devise.. Here i am trying to select one or multiple checkbox to do following actions:block,unblock,delete..After blocking a user he/she can’t login and hit status will be updated to block..if any of the user unblock him then he can login..Deleted user can register..

This is my view code:

 <div class="card">
      <div class="card-header">
        User Management
      </div>
      <div class="card-body">
        <%= form_tag(admin_users_path, method: :post, id: "bulk-actions-form") do %>
          <table class="table table-light table-hover table-striped">
            <thead class="table-dark">
              <tr>
                <th><input type="checkbox" id="select-all" onclick="toggleAllCheckboxes()"></th>
                <th>ID</th>
                <th>Name</th>
                <th>Email</th>
                <th>Last Login Time</th>
                <th>Registration Time</th>
                <th>Status</th>
              </tr>
            </thead>
            <tbody>
              <% @users.each do |user| %>
                <tr>
                  <td><input type="checkbox" name="user_ids[]" value="<%= user.id %>"></td>
                  <td><%= user.id %></td>
                  <td><%= user.username %></td>
                  <td><%= user.email %></td>
                  <td><%= user.last_sign_in_at %></td>
                  <td><%= user.created_at %></td>
                  <td><%= user.status %></td>
                </tr>
              <% end %>
