当尝试在ModelAdmin中将多个关系用作内联时,会导致错误admin。E105位于底部,但在正常情况下,没有内联,工作正常。以下是代码:

模型。py

class Reference(models.Model):
    url = models.UrlField()
    ...


class BaseModel(models.Model):
    ...
    references = models.ManyToManyField(
            Reference,
            related_name="references_%(app_label)s_%(class)s_related",
        )

    class Meta:
        abstract=True


class Case(BaseModel)
    ...
    name = models.CharField(max_length=255)
    ...

管理py

class InlineReference(admin.TabularInline):
    model = BaseModel.references.through


class CaseAdmin(admin.ModelAdmin):
    ...
    inlines = [InlineReference, ]
    exclude = ['references', ]
    ...

错误消息是:

SystemCheckError: System check identified some issues:
ERRORS:
<class 'admin.CaseAdmin'>: (admin.E105) 'admin.InlineReference' must have a 'model' attribute.

我正试着跟踪 here .

必须设置模型属性引用模型。

class InlineReference(admin.StackedInline):
    model = Reference


class BaseAdmin(admin.ModelAdmin):
    ...
    inlines = [InlineReference, ]
    ...

admin.site.register(Base, BaseAdmin)
