当我从我的用户模型中删除以下这些行时，它工作正常。

has_settings do |s|
s.key :production_overview_report_mailer, defaults: { enabled: false }
end

有人可以帮助我使用带有莱德曼轨道设置 (2.4.3( 和 rails_admin (1.4.2( 的 rails 5.1.6 吗？

我通过放置以下内容来覆盖app/views/rails_admin/main/_delete_notice.html.erb来修复它。

<% object = delete_notice %>
<li style="display:block; margin-top:10px">
<span class="label label-default">
<%= @abstract_model.pretty_name %>
</span>
<% wording = object.send(@model_config.object_label_method) %>
<% if show_action = action(:show, @abstract_model, object) %>
<%= link_to(wording, url_for(action: show_action.action_name, model_name: @abstract_model.to_param, id: object.id), class: 'pjax') %>
<% else %>
<%= wording %>
<% end %>
<ul>
<% @abstract_model.each_associated_children(object) do |association, children| %>
<% humanized_association = @abstract_model.model.human_attribute_name association.name %>
<% limit = children.count > 12 ? 10 : children.count %>
<% children.first(limit).each do |child| %>
<%= content_tag :li, class: dom_class(child) do %>
<% if child.class.name != "RailsSettings::SettingObject" %>
<% child_config = RailsAdmin.config(child) %>
<%= humanized_association.singularize %>
<% wording = child.send(child_config.object_label_method) %>
<% if child.id && (show_action = action(:show, child_config.abstract_model, child)) %>
<%= link_to(wording, url_for(action: show_action.action_name, model_name: child_config.abstract_model.to_param, id: child.id), class: 'pjax') %>
<% else %>
<%= wording %>
<% end %>
<% end %>
<% end %>
<% end %>
<% if children.count > limit %>
<li>
<%= t('admin.misc.more', count: children.count - limit, models_name: humanized_association) %>
</li>
<% end %>
<% end %>
</ul>
</li>
