Django过滤器后端 [英] Django Filter Backend

问题描述

我正在使用Django rest framework API，我正在尝试通过first_name或last_name或两者都进行过滤。
这是我的 ContactViewSet.py ：

I'm working with Django rest framework API, I am trying to make a filter by first_name or by last_name or by both of them. This is my ContactViewSet.py :

class ContactViewSet(viewsets.ModelViewSet):
    queryset = Contact.objects.all()
    serializer_class = ContactSerializer
    filter_backends = (DjangoFilterBackend, )
    filter_fields = ('first_name', 'last_name')
    lookup_field = 'idContact'

我的DRF设置：

REST_FRAMEWORK = {
    'DEFAULT_FILTER_BACKENDS': ('django_filters.rest_framework.DjangoFilterBackend',),
}

我的actuel请求网址如下：

My actuel request url looks like :

http://localhost:8000/api/v1/contacts/?first_name=Clair&last_name=Test

但是我正在寻找这样的东西：

But I'm looking for something like this :

http://localhost:8000/api/v1/contacts/?first_name=Cl**&last_name=Tes**

任何帮助将不胜感激..

Any help would be appreciated ..

推荐答案

我通过修改类ContactFilter来解决我的问题，

I solved my problem by modifying my class ContactFilter like this:

import django_filters
from .models import Contact

class ContactFilter(django_filters.FilterSet):
   class Meta:
        model = Contact
        fields = {
            'first_name': ['startswith'],
            'last_name': ['startswith'],
        }
        together = ['first_name', 'last_name']

在我看来，我只需要这样做：

And in my view I just had to do this :

class ContactViewSet(viewsets.ModelViewSet):
    queryset = Contact.objects.all()
    serializer_class = ContactSerializer
    filter_class = ContactFilter

我的请求网址如下所示：

My request url looks like :

http://localhost:8000/api/v1/contact/?first_name__contains=Cl&last_name__contains=Tes

但是我仍然想知道我是否可以有这样的东西在Django中

But I still wonder if I can have something like this in Django

http://localhost:8000/api/v1/contacts/?first_name=Cl**&last_name=Tes**
