Django过滤器，如何使多个字段搜索?(使用django-filter！) [英] Django-filter, how to make multiple fields search? (with django-filter!)

问题描述

如何使用Django过滤器从以下模型中搜索多个字段:

How can I make multiple fields search with Django-filter from model like:

class Location(models.Model):
    loc = models.CharField(max_length=100, blank=True)
    loc_mansioned = models.CharField(max_length=100, blank=True)
    loc_country = models.CharField(max_length=100, blank=True)
    loc_modern = models.CharField(max_length=100, blank=True)

我的网站上需要一个输入字段，可以在位置模型的所有字段中进行搜索

I need one input field on my website, that can search over all fields of Location model

推荐答案

您可能可以创建一个自定义过滤器，并执行以下操作:

You can probably create a custom filter and do something like this:

from django.db.models import Q
import django_filters


class LocationFilter(django_filters.FilterSet):
    q = django_filters.CharFilter(method='my_custom_filter')

    class Meta:
        model = Location
        fields = ['q']

    def my_custom_filter(self, queryset, name, value):
        return Location.objects.filter(
            Q(loc__icontains=value) | Q(loc_mansioned__icontains=value) | Q(loc_country__icontains=value) | Q(loc_modern__icontains=value)
        )

这将按那些字段中的任何一个进行过滤.您可以将 contains 替换为所需的任何内容.

This would filter by any of of those fields. You can replace the icontains with whatever you want.
