我如何在Django管理中像（在value1-value2之间搜索）范围之间应用价格搜索

在我的django管理项目中，我具有字段平衡。并且我想根据用户的需要在2000-5000,5000-7000 ..... value1-vvalue2，value3-value4 ..之类的范围内搜索平衡，但是我不知道如何在我的代码中应用它。我应用了常规搜索，例如按名称，按城市等...我的代码如下

models.py

cust_id=models.CharField(max_length=50)
    name_regex = RegexValidator(regex=r'^[a-zA-Z\s]+$', message="only characters are allowed")
    cust_first_name=models.CharField(validators=[name_regex],max_length=50)
    cust_middle_name=models.CharField(validators=[name_regex],max_length=50,blank=True, null=True)
    cust_last_name=models.CharField(validators=[name_regex],max_length=50,blank=True, null=True)
    father_name=models.CharField(validators=[name_regex],max_length=50)
    village_name=models.CharField(validators=[name_regex],max_length=50)
balance=models.PositiveIntegerField(default=0,blank=True, null=True)

管理员

from django.contrib import admin
from account.models import *
from import_export import resources
from django import forms
from import_export.admin import ImportExportModelAdmin
# from webcam.fields SSSSSSimport CameraField
from django.contrib.admin.options import FORMFIELD_FOR_DBFIELD_DEFAULTS
from webcam import widgets
from webcam.fields import CameraField
FORMFIELD_FOR_DBFIELD_DEFAULTS[CameraField] = {'widget': widgets.CameraWidget}

class AccounttResource(resources.ModelResource):
    class Meta:
        model=Account
        import_id_fields = ['cust_id']
        # fields=('cust_first_name','balance','village_name')


class AccountAdmin(ImportExportModelAdmin,admin.ModelAdmin):
# class AccountAdmin(admin.ModelAdmin):
# list_filter = [ValueRangeFilter, ]
    search_fields=['cust_id','cust_first_name','village_name','balance' ]
    resource_class = AccounttResource
    list_display = ['cust_first_name','cust_id']
    list_display_links = ('cust_first_name',)
    readonly_fields=('image_tag_thumb','image_tag','cust_id','balance')


class ReportingResource(resources.ModelResource):
    class Meta:
        model=Account
        import_id_fields = ['cust_id']
        fields=('cust_first_name','balance','village_name')

class ReportingAdmin(ImportExportModelAdmin,admin.ModelAdmin):
    # form=AccountPhone
    # fields = ('cust_first_name', 'balance')
    # list_filter = [ValueRangeFilter, ]
    search_fields=['cust_id','cust_first_name','village_name','balance' ]
    resource_class = ReportingResource
    list_display = ['cust_first_name','balance','village_name','total_payment_received']
    list_display_links = ('cust_first_name',)
    readonly_fields=('image_tag_thumb','image_tag','cust_id',)


admin.site.register(Account,AccountAdmin)
admin.site.register(Reporting,ReportingAdmin)

现在我该怎么做才能在我的余额字段代码中应用该范围搜索。
