在 django admin 中向 search_fields 添加一个选择字段

Question

比如说，我有一个带有如下所示选择字段的模型：

STARTED = 1
DONE = 0

STATUSES = {
    (STARTED, 'Started'),
    (DONE, 'Done'),
}

status = models.IntegerField(choices=STATUSES)

我想将字段 status 添加到 admin.py 中的 search_fields = ()，如下所示。

search_fields = (status,)

它可以按整数搜索，但我想根据显示文本 "Done" 和 "Started."

进行搜索

您应该可以通过重写模型管理员的 get_search_results 方法来完成此操作。

# This dictionary lets you convert the text back to the integer.
# You might prefer to build it dynamically instead.

TEXT_TO_STATUS_INTEGER = {
    'Started': 1,
    'DONE': 0,
}

class MyModelAdmin(admin.ModelAdmin):
    def get_search_results(self, request, queryset, search_term):
        queryset, use_distinct = super(PersonAdmin, self).get_search_results(request, queryset, search_term)
        if search_term in TEXT_TO_STATUS_INTEGER:
            queryset |= self.model.objects.filter(status=TEXT_TO_STATUS_INTEGER[search_term])
    return queryset, use_distinct
