Question

我有一个m2m关系，在我的AdminForm中，我会使用raw_id_fields而不是filter_horizontal选项。为了解释，我更喜欢raw_id_fields而不是filter_horizontal选项，因为记录已经被分类了。因此，在弹出窗口中，用户可以通过类别进行搜索和过滤。但有两点我无法弄清楚：

可以在弹出窗口中选择多个记录
在input_field

Answer 1

这是可能的。要选择多条记录，您需要在dismissRelatedLookupPopup()中覆盖默认django/contrib/admin/static/admin/js/admin/RelatedObjectLookups.js，方法是将您的脚本包含在Media或小部件的ModelAdmin类中：

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);

Django默认不支持此功能。 djangosnippets.org有一些片段，您可能需要查看它们。

最后我使用了修改后的https://django-salmonella.readthedocs.org/en/latest/。我没有显示输入字段并在表格中显示所选记录。

在raw_id_fields中一次插入更多记录
