python 新手，一个简单的筛选把我搞懵逼了。第一个 model: electrode

from django.db import models

# Create your models here.

class Electrode(models.Model):
    name = models.CharField(max_length=32, null=True)

第二个 model: electrode_log

from django.db import models
from Application.views.electrode.models import Electrode

# Create your models here.

class ElectrodeLog(models.Model):
    electrode = models.ForeignKey(Electrode, on_delete=models.CASCADE, default=None, null=True)

用的视图集 ModelViewSet ，求教怎么在筛选到 Electrode 表的 name ，万分感激。

from django_filters import rest_framework as filters
from rest_framework import viewsets

class ElectrodeLogFilter(filters.FilterSet):
....electrode__name = filters.CharFilter(lookup_expr='icontains')

class ElectrodeLogViewSet(viewsets.ModelViewSet):
....filterset_class = ElectrodeLogFilter

....为空格
