我在django admin中一直在the docs查看search_fields
以尝试搜索相关字段。
所以,这是我的一些模特。
# models.py
class Team(models.Model):
name = models.CharField(max_length=255)
class AgeGroup(models.Model):
group = models.CharField(max_length=255)
class Runner(models.Model):
"""
Model for the runner holding a course record.
"""
name = models.CharField(max_length=100)
agegroup = models.ForeignKey(AgeGroup)
team = models.ForeignKey(Team, blank=True, null=True)
class Result(models.Model):
"""
Model for the results of records.
"""
runner = models.ForeignKey(Runner)
year = models.IntegerField(_("Year"))
time = models.CharField(_("Time"), max_length=8)
class YearRecord(models.Model):
"""
Model for storing the course records of a year.
"""
result = models.ForeignKey(Result)
year = models.IntegerField()
我想要的是YearRecord
管理员能够搜索跑步者所属的团队。但是,只要我尝试将Runner
FK关系添加到搜索字段,我就会在搜索时出错; TypeError: Related Field got invalid lookup: icontains
所以,这里是管理员设置,我希望能够搜索关系。我确定这与文档匹配,但我在这里误解了什么吗?这可以解决吗? result__runner
是否会扩展到Runner
模型的团队字段?
# admin.py
class YearRecordAdmin(admin.ModelAdmin):
model = YearRecord
list_display = ('result', 'get_agegroup', 'get_team', 'year')
search_fields = ['result__runner', 'year']
def get_team(self, obj):
return obj.result.runner.team
get_team.short_description = _("Team")
def get_agegroup(self, obj):
return obj.result.runner.agegroup
get_agegroup.short_description = _("Age group")
答案 0 :(得分:23)
文档内容如下:
这些字段应为某种文字字段,例如CharField
或TextField
。
所以你应该使用'result__runner__team__name'
。
