Rails 如何根据多个模型做出决策？

Question

i have three model project_site, project_manager and human_resource. each model has status Boolean attribute i want to print "approve" only if all status==true but want to print "reject" if any one of the status is set to false. each status has nil value by default.

        <% if project_site.human_resources.empty? %>
              <td class="pending fi-eye"><%= " Pending" %></td>
            <% elsif %>
              <% project_site.human_resources.each do |human_resource| %>
                <% if human_resource.status == false %>
                  <td class="rejected fi-x"><%= ' Rejected' %></td>
                <% elsif human_resource.status == true %>
                  <td class="approved fi-check"><%= " Approved" %></td>
                <% end %>
              <% end %>

              <% elsif %>
                <% project_site.project_directors.each do |project_director| %>
                  <% if project_director.status == false %>
                    <td class="rejected fi-x"><%= ' Rejected' %></td>
                  <% end %>
                <% end %>

                <% elsif %>
                  <% project_site.project_managers.each do |project_manager| %>
                    <% if project_manager.status == false %>
                      <td class="rejected fi-x"><%= ' Rejected' %></td>
                    <% end %>
                  <% end %>
            <% end %>

Answer 1

Try something like:

is_approved = project_site.human_resources.all?{|e| e.status } # or .all?(&:status) will check if status true for all records

you can even simplify

all_approved = (project_site.project_managers +  project_site.human_resources + project_site.project_directors).all?(&:status)

it doesn't look perfect and I suggest to move it to the model.
