我有以下代码：
admin.py
from django import template
from django.shortcuts import render_to_response
from django.contrib import admin
from models import *
from django.contrib.auth.admin import UserAdmin as DjangoUserAdmin
from django.contrib.auth.models import User
from actions import export_as_csv_action
from django import forms
class TelefoneIPInline(admin.StackedInline):
model = MovimentoTelefoneIP
extra = 1
list_filter = ['cliente']
class TelefoneIPAdmin(admin.ModelAdmin):
actions = [export_as_csv_action("Exportar para Excel", fields=['mac','modelo','fornecedor','get_clientes'])]
list_display = ('mac', 'modelo','get_clientes')
search_fields = ['mac']
list_filter = ['modelo','fornecedor']
def get_clientes(self, obj):
clientes = [m.cliente for m in obj.movimentotelefoneip_set.all()]
if clientes:
return (clientes[-1])
else:
return "Selecione um local"
get_clientes.short_description = 'Clientes'
inlines = [TelefoneIPInline]
我使用get_clientes来显示list_display中内联类的字段，我可以在list_filter中使用ir吗？
这是我的models.py
# -*- coding: UTF-8 -*-
from django.db import models
from detalhamento.models import *
from django.contrib.auth.models import User
class TelefoneIP(models.Model):
mac = models.CharField(max_length=12, help_text="Este campo deve ter 12 digitos", unique=True)
modelo = models.ForeignKey(ModeloTelefoneIP)
fornecedor = models.ForeignKey(Fornecedor)
obs = models.TextField(max_length=500, null=True, blank=True)
class MovimentoTelefoneIP(models.Model):
equipamento = models.ForeignKey(TelefoneIP)
cliente = models.ForeignKey(Cliente)
sentido = models.ForeignKey(sentido)
nfentrada = models.IntegerField(verbose_name="Nota fiscal de entrada", null=True, blank=True)
dataentrada = models.DateField(verbose_name="Data de entrada", null=True, blank=True)
nfvenda = models.IntegerField(verbose_name="Nota fiscal de saída", null=True, blank=True)
datavenda = models.DateField(verbose_name="Data de saída", null=True, blank=True)
我已经添加了导入。
