我有两个通过 ManyToManyField 关系相关的 Django 模型。一切正常，除了内联添加下拉列表列出丑陋的自动创建的对象名称，而不是让我格式化它。我该如何指定？
楷模：
class Job(models.Model):
type = models.CharField(max_length=32, choices=JobChoices)
guid = models.CharField(max_length=32)
title = models.CharField(max_length=256)
started_time = models.DateTimeField()
ended_time = models.DateTimeField(blank=True, null=True)
enabled = models.BooleanField(default=False)
running = models.BooleanField(default=False)
working_job_status = models.CharField(max_length=32, choices=StatusCoices)
working_job_length = models.IntegerField(blank=True, null=True)
working_job_progress = models.IntegerField(blank=True, null=True)
working_job_eta_sec = models.IntegerField(blank=True, null=True)
RepeatUnit = (
('s', 'Second'),
('m', 'Minute'),
('h', 'Hour'),
('d', 'Day'),
('W', 'Week'),
('M', 'Month'),
('Y', 'Year'),
)
class Schedule(models.Model):
title = models.CharField(max_length=128)
job = models.ManyToManyField(Job, blank=True, null=True)
start_time = models.DateTimeField(null=False)
end_time = models.DateTimeField(blank=True, null=True)
repeat_unit = models.CharField(blank=True, null=True, max_length=1, choices=RepeatUnit)
repeat_every = models.IntegerField(blank=True, null=True)
repeat_max_count = models.IntegerField(blank=True, null=True)
def __unicode__(self):
return f'{self.title}'
行政：
class ScheduleAdmin(admin.ModelAdmin):
list_display = ['id', 'title', 'start_time', 'end_time', 'repeat_unit', 'repeat_every', 'repeat_max_count']
class ScheduleInline(admin.TabularInline):
model = Schedule.job.through
min_num = 0
extra = 0
# fields = ('title', )
verbose_name = "Schedule"
verbose_name_plural = "Schedules"
class JobAdmin(admin.ModelAdmin):
list_display = ['id', 'type', 'guid', 'title', 'started_time', 'ended_time', 'enabled', 'running', 'progress']
inlines = [ScheduleInline,]
admin.site.register(Schedule, ScheduleAdmin)
admin.site.register(Job, JobAdmin)
而且，当我点击内联下拉菜单时，我得到：
