Django filter_horizo​​ntal过滤 [英] Django filter_horizontal filtering

问题描述

我有2种型号与M2M类型的关系相关。我在管理员中使用 filter_horizo​​ntal 来编辑我的实体。

但是，我想要控制在 filter_horizo​​ntal 小部件的左侧显示的内容。例如，我想过滤并显示符合某些标准的实体。任何建议请问？

谢谢！

解决方案

发现它！

  class MyModelAdmin（admin.ModelAdmin）：
 def formfield_for_manytomany（self，db_field，request，** kwargs）
如果db_field.name ==cars：
 kwargs [queryset] = Car.objects.filter（owner = request.user）
返回超级（MyModelAdmin，self ）.formfield_for_manytomany（db_field，request，** kwargs）
  

ModelAdmin.formfield_for_manytomany（db_field，request，** kwargs）

I have 2 models related by M2M type of relationship. I use filter_horizontal in the admin for editing my entities.

However, I would like to have a control on what is presented in the left side of the filter_horizontal widget. For example, I would like to filter and show only those entities that match some certain criteria. Any recommendation please?

Thank you!

解决方案

I think I found it!

class MyModelAdmin(admin.ModelAdmin):
def formfield_for_manytomany(self, db_field, request, **kwargs):
    if db_field.name == "cars":
        kwargs["queryset"] = Car.objects.filter(owner=request.user)
    return super(MyModelAdmin, self).formfield_for_manytomany(db_field, request, **kwargs)

ModelAdmin.formfield_for_manytomany(db_field, request, **kwargs)
