我正在尝试在管理员列表视图中显示外键“公司名称”。但是，列表视图仅显示公司的 (None)。我做错了什么？

管理员.py

class CampaignAdmin(admin.ModelAdmin):
    #fields = ['name', 'Company_name', 'active', 'modified', 'created']
    list_display = ['name', 'related_company', 'active', 'modified', 'created']
    list_filter = ['active']
    search_fields = ['name']
    sortable_field_name = "name"
    autocomplete_lookup_fields = {
        'name': ['name'],
        }

    def related_company(self, obj):
        return '%s'%(obj.Company.name)
    related_company.short_description = 'Company'


admin.site.register(Campaign, CampaignAdmin)

模型.py

class Company(models.Model):
    companyid = models.CharField(max_length=255, primary_key=True, db_column='companyID')
    name = models.CharField(max_length=105)
    logourl = models.CharField(max_length=255, db_column='logoURL')
    website = models.CharField(max_length=255, blank=True)
    active = HibernateBooleanField(default=False)
    created = models.DateTimeField()
    modified = models.DateTimeField(null=True, blank=True)

    class Meta:
        db_table = u'company'
        ordering = ['name']

    @staticmethod
    def autocomplete_search_fields():
        return ("id__iexact", "name__icontains",)

    def __unicode__(self):
        return self.name


class Campaign(models.Model):
    campaignid = models.CharField(max_length=255, primary_key=True, db_column='campaignID')
    name = models.CharField(max_length=105)
    active = HibernateBooleanField(default=False)
    created = models.DateTimeField()
    modified = models.DateTimeField(null=True, blank=True)
    companyid = models.ForeignKey(Company, null=True, db_column='companyID', blank=True)

    class Meta:
        db_table = u'campaign'


    def __unicode__(self):
        return self.name

您的Campaign模型没有Company属性 - ForeignKey 是 field companyid。您需要将功能更改为

def related_company(self, obj):
    return obj.companyid.name
related_company.short_description = 'Company'

而且由于__unicode__()公司对象的方法无论如何都会返回名称，因此您可能无论如何都不需要自定义函数-我认为您可以将外键字段直接放在显示列表中：

list_display = ['name', 'companyid', 'active', 'modified', 'created']

以这种方式链接到 ForeignKey 对象时要考虑的附加功能是related_company.allow_tags = True在函数上设置。

这将使您可以返回 HTML 并将其呈现为列表视图中的可用链接。
