如何使用石墨烯-django 对多个字段中的图标使用 OR 条件

Question

我在 Django 中有以下模型：

class JobPost(models.Model):
    company = models.CharField(blank=True, max_length=30, null=True)
    job = models.CharField(blank=True, max_length=30, null=True)
    category = models.CharField(blank=True, max_length=30, null=True)
    description = models.TextField(blank=True, max_length=500, null=True)
    created_at = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.job

我有以下石墨烯模式：

class JobPostNode(DjangoObjectType):
    class Meta:
        # Assume you have an Animal model defined with the following fields
        model = JobPost
        filter_fields = {
            'company': ['exact', 'icontains', 'istartswith'],
            'job': ['exact', 'icontains', 'istartswith'],
            'category': ['exact', 'icontains', 'istartswith'],
            "description": ['exact', 'icontains', 'istartswith'],
        }
        interfaces = (relay.Node,)


class Query(graphene.ObjectType):

    job = relay.Node.Field(JobPostNode)
    all_jobs = DjangoFilterConnectionField(JobPostNode)


schema = graphene.Schema(query=Query)

我想使用icontains，而我将根据 OR 而不是 AND 获取数据；例如以下查询：

{
  allJobs(job_Icontains: "t", company_Icontains: "v") {
    edges {
      node {
        company
        job
      }
    }
  }
}

应返回工作中包含字母“t”或公司中包含字母“v”的数据，而不是工作中包含字母“t”和公司中包含字母“v”的数据。我该怎么做？

我发现了如何做到这一点here！对于我的架构，我写了这个：

import graphene
from api_rest.models import JobPost
from django.db.models import Q
from graphene_django import DjangoObjectType


class JobType(DjangoObjectType):
    class Meta:
        model = JobPost


class Query(graphene.ObjectType):
    jobs = graphene.List(
        JobType, search=graphene.String(), first=graphene.Int(), skip=graphene.Int()
    )

    def resolve_jobs(self, info, search=None, first=None, skip=None, **kwargs):
        queryset = JobPost.objects.all()
        if search:
            filter = (
                Q(company__icontains=search)
                | Q(description__icontains=search)
                | Q(category__icontains=search)
            )
            queryset = queryset.filter(filter)

        if skip:
            queryset = queryset[skip:]

        if first:
            queryset = queryset[:first]
        return queryset


schema = graphene.Schema(query=Query)

现在，使用以下查询，我得到了我想要的结果：

{
  jobs(search: "transpo") {
    id
    company
    category
    job
    createdAt
  }
}
