The Bootstrap modal is refusing to pop out as intended

My attempt to showcase a modal on ruby on rails has hit a snag. I have set up a view button that should trigger the appearance of the modal when clicked, but it’s not functioning correctly. The issue is evident in this image, where the modal appears darkened and unclickable. Here's the code snippet:

index.html.erb

            <tbody>
              <% @quotations.each do |quotation| %>
                <tr>
                  <td><%= quotation.customer.name %></td>
                  <td><%= quotation.build_quotation_number %></td>
                  <td><%= quotation.reference_no %></td>
                  <td align="center"><%= quotation.customer.tin %> . 
 </td>
                  <td align="center">
                    <% if current_administrator.admin? || quotation.created_by_id == current_administrator.id %>
                      <%= link_to ('<i class="ti-pencil-alt"> </i>').html_safe, edit_quotation_path(quotation), class: "btn btn-icon btn-fill btn-github", title: "Edit Quotation " + quotation.build_quotation_number, 'data-toggle' => 'tooltip', 'data-placement' => 'top' %>
                    <% end %>

                   <button type="button" class="btn btn-icon btn-fill btn-linkedin" title="View Quotation" data-toggle="modal" data-target="#view_quotation_modal"><i class="ti-eye"> </i></button>

                    <% if current_administrator.admin? || quotation.created_by_id == current_administrator.id %>
                      <%= link_to ('<i class="ti-trash"> </i>').html_safe, quotation_path(quotation), data: {:confirm => 'Are you sure you want to delete this quotation?'}, method: :delete, class: "btn btn-icon btn-fill btn-danger", title: "Delete Quotation " + quotation.build_quotation_number, 'data-toggle' => 'tooltip', 'data-placement' => 'top' %>

                      +
                    <% end %>
                     <%= render partial: 'quotations/modal/view_quotation_modal', locals: { quotation: @quotation } %>
                  </td>
                </tr>
              <% end %>

            </tbody>

Answer №1

You seem to be approaching this the wrong way. By loading a partial of the modal in a loop, you will end up with multiple instances of the view_quotation_modal.

For proper implementation, the bootstrap modal should always be placed outside of the rest of your code, preferably at the very bottom.

To achieve this, add the following div to your main layout file, such as application.html.erb

<div id="modal-window" class="modal fade" role="dialog" data-backdrop="static"></div>

A better approach would be to create a separate action that handles displaying the modal.

<button type="button" class="btn btn-icon btn-fill btn-linkedin" title="View Quotation" data-toggle="modal" data-target="#view_quotation_modal"><i class="ti-eye"> </i></button>

Upon clicking the above button, you can make an ajax call to a Rails controller or use link_to instead of a button to trigger the controller action and pass any necessary parameters.

In the Rails controller:

def show_quotation
  # implement your logic here 
  respond_to do |format|
    format.html
    format.js 
   end
end

show_quotation.js.erb

$("#modal-window").html("<%= escape_javascript(render 'view_quotation_modal') %>");
$("#modal-window").modal();

Note that you can access all instance variables in the partial.
