如何过滤Django2的autocomplete_fields中的选择? [英] How to filter choices in Django2's autocomplete_fields?
问题描述
在Django 2.0中, autocomplete_fields 已添加,这很棒。
In Django 2.0, autocomplete_fields was added, which is great.
没有autocomplete_fields,我可以使用 formfield_for_foreignkey 。
Without autocomplete_fields, I can change the queryset of a ForeignKeyField using formfield_for_foreignkey.
但是将两者结合在一起是行不通的-看来自动完成功能的选项列表是动态的,并且来自不同的url,而不是来自当前形式。
But combining the two together doesn't work - it looks like the list of options for autocomplete is dynamic and coming from a different url, instead of from the current form.
问题是-
如何在自动完成小部件中更改查询集?
How can I change the queryset in the autocomplete widget?
推荐答案
重写ModelAdmin的 get_search_results
方法来使用所需的查询。您可以在 get_queryset
方法的视图中看到,该视图提供用于获取查询集的自动完成字段的数据-此答案的来源为 https://github.com/django/django/blob/03dbdfb9bb /django/contrib/admin/views/autocomplete.py#L42 。
Override the ModelAdmin's get_search_results
method to use the query you want. You can see in the get_queryset
method for the view providing the data for autocomplete fields that it's used to get the queryset - the source as of this answer is https://github.com/django/django/blob/03dbdfd9bbbbd0b0172aad648c6bbe3f39541137/django/contrib/admin/views/autocomplete.py#L42.
