django - 在 raw_id_fields 中一次插入更多记录

Question

我有一个 m2m 关系，在我的 AdminForm 中我会使用 raw_id_fields 而不是 filter_horizo​​ntal 选项。为了解释，我更喜欢 raw_id_fields 而不是 filter_horizo​​ntal 选项，因为记录已经分类。因此，在弹出窗口中，用户可以通过类别进行搜索和过滤。但是有两点我想不通：

• 在弹出窗口中选择多个记录的可能性
• 在 input_field 中显示真实姓名而不是 pk

1. 这是可能的。为了选择多个记录，您需要通过将脚本包含在您的或小部件的类中dismissRelatedLookupPopup()来覆盖默认值：django/contrib/admin/static/admin/js/admin/RelatedObjectLookups.jsMediaModelAdmin

   var dismissRelatedLookupPopup = (function(prev, $) {
       return function(win, chosenId) {
           var name = windowname_to_id(win.name);
           var elem = document.getElementById(name);
   
           // 1. you could add extra condition checking here, for example
           if ($(elem).hasClass('my_raw_id_ext_cls')) { // add this class to the field
           //     ...logic of inserting picked items from the popup page
           } 
           else { // default logic
               prev(win, chosenId);
           }
   
           // 2. or you could copy the following part from RelatedObjectLookups.js ...
           if (elem.className.indexOf('vManyToManyRawIdAdminField') != -1 && elem.value) {    
               elem.value += ',' + chosenId;
               // 2. and add a return. Remember this acts globally.
               return;
           } else {
               document.getElementById(name).value = chosenId;
           }
   
           // 3. the following line cause the popup to be closed while one item is picked. 
           // You could comment it out, but this would also affect the behavior of picking FK items.
           win.close(); 
   
       }
   })(dismissRelatedLookupPopup, django.jQuery);
   

2. Django 默认不支持这个。djangosnippets.org上有一些片段，你可能想看看它们。

最后，我使用了修改后的https://django-salmonella.readthedocs.org/en/latest/。我不显示输入字段并在表格中显示选定的记录。
