View for admin in rails

问题

I have a parent table, child Table, funding table. Parent logs in, add his children and then apply for funding for each child.

parent.rb

class Parent < ApplicationRecord
    has_many :children, dependent: :destroy
    has_many :secondaryparents, dependent: :destroy
end

funding.rb

class Funding < ApplicationRecord
    has_many :organisations, dependent: :destroy
    belongs_to :child
end

child.rb

class Child < ApplicationRecord
    belongs_to :parent
    has_many :fundings, dependent: :destroy
end

Parent has a field as admin. if set as true parent acts as admin. application.html.erb is the view of admin. I am able to display all the primary parents and their children in front of each other. I need help with displaying the funding applications of the children in front of them.

application.html.erb

<div class="row">
<!-- .main_column_css -->
  <div class="col-sm-9 col-xs-12">
    <div class="content" role="main" id="main-content">
      <article>
        <div ><h1>Application Status</h1>
            <div class="table-responsive">
              <table class="table table-bordered">
                <thead>
                  <tr>
                   <th>Primary Parent Name</th>
                   <!--  <th>Financial Status</th> -->
                    <th>Child Name</th>
                    <th>Activity</th>
                    <th>Organisation</th>
                    <th>Activity Start Date</th>
                    <th>Date Submitted</th>
                    <th>Amount Requested</th>
                    <th>Funds Available</th>
                    <th>Status</th>
                  </tr>
                </thead>
                <tbody>
  <% @parents.each do |parent| %>
    <% parent.children.each do |child| %>
      <tr> 
        <td><%= parent.parent_1_firstname %></td>
        <td><%= child.firstname %></td>

      </tr>
    <% end %>
  <% end %>
</tbody>      
              </table>
            </div>
            <div class="clearfix"></div>
          </div>           
      </article>
    </div>
    <!-- .content -->
  </div>
</div>

financial status, activity, activity start date, date submitted, amount requested, funds available are all fields of funding table. Funding table has the child_id. child table has parent_id. Kindly help

Update

<% @parents.each do |parent| %>
    <% parent.children.each do |child| %>
     <% child.fundings.each do |funding| %>
      <tr> 
        <td><%= parent.parent_1_firstname %></td>
        <td><%= child.firstname %></td>
        <td><%= funding.type_of_activity %></td>
      </tr>
    <% end %>
  <% end %>
<% end %>

回答1:

you can do child.fundings.each do |funding| and then do all the attributes for funding.
