Django Admin 中缺少内联

Question

请参阅下面的 models.py/admin.py

当我尝试更改或添加 FashionMaleModel 时，内联不会出现，但它们会出现在 FashionFemaleModel 中。如果我更改管理站点的注册顺序，将男性置于女性之下，则内联仅显示在 FashionMaleModel 中，而不显示在 FashionFemaleModel 中。

为什么我的内联只出现在其中之一中？

谢谢！

我已经截断了这些模型，因为它们太多了。此外，FashionObject/FashionPage 是我作为自定义 CMS 的一部分创建的基类，其中包含 id、名称、publish_date 等。

models.py：admin.py

class FashionModelRole(models.Model):
    title = models.CharField(max_length=255,)

class FashionModelContributor(models.Model):
    role = models.ForeignKey(FashionModelRole)
    person = models.ForeignKey(FashionModelPerson, related_name='contributions')

class FashionModel(FashionObject):
    gender = models.CharField(max_length=1,choices=(('F','Female'),('M','Male')), 
editable=False)

class FashionExperience(models.Model):
    model = models.ForeignKey(FashionModel, related_name = 'experience')
    division = models.ForeignKey(FashionDivision, related_name = 'levels')
    experience = models.CharField(max_length=1,choices=(('5','Professional'),('4','Advanced'),('3','Intermediate'),('2','Developing'),('1','Recreational'),))

class FashionMaleModel(FashionModel):
    jacket_size = MeasurementField(max_length=6, blank=True, null=True)

    def __init__(self, *args, **kwargs):
        super(FashionMaleModel, self).__init__(*args, **kwargs)
        self.gender = 'M'

class FashionFemaleModel(FashionModel):
    dress_size = MeasurementField(max_length=6, blank=True, null=True)

    def __init__(self, *args, **kwargs):
        super(FashionFemaleModel, self).__init__(*args, **kwargs)
        self.gender = 'F'

class FashionModelPhoto(models.Model):
    model = models.ForeignKey(FashionModel, related_name = 'photos')
    contributors = models.ManyToManyField(FashionModelContributor, null=True, blank=True)

：

class FashionExperienceInline(admin.TabularInline):
    model = FashionExperience

class FashionModelPhotoInline(admin.TabularInline):
    model = FashionModelPhoto

class FashionDivisionAdmin(FashionPageAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionDivisionAdmin, self).__init__(*args, **kwargs)

class FashionModelAdmin(FashionObjectAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionModelAdmin, self).__init__(*args, **kwargs)
        self.inlines += (
            FashionModelPhotoInline,
            FashionExperienceInline,
            )

class FashionMaleModelAdmin(FashionModelAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionMaleModelAdmin, self).__init__(*args, **kwargs)

class FashionFemaleModelAdmin(FashionModelAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionFemaleModelAdmin, self).__init__(*args, **kwargs)

class FashionModelPersonAdmin(admin.ModelAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionModelPersonAdmin, self).__init__(*args, **kwargs)

class FashionModelRoleAdmin(admin.ModelAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionModelRoleAdmin, self).__init__(*args, **kwargs)        

class FashionModelContributorAdmin(admin.ModelAdmin):
    def __init__(self, *args, **kwargs):
        super(FashionModelContributorAdmin, self).__init__(*args, **kwargs)

admin.site.register(FashionMaleModel, FashionMaleModelAdmin)
admin.site.register(FashionFemaleModel, FashionFemaleModelAdmin)
admin.site.register(FashionDivision, FashionDivisionAdmin)
admin.site.register(FashionModelPerson, FashionModelPersonAdmin)
admin.site.register(FashionModelRole, FashionModelRoleAdmin)
admin.site.register(FashionModelContributor, FashionModelContributorAdmin)

Answer 1

我从 FashionMaleModelAdmin 和 FashionFemaleModelAdmin 类中取出了 __init__ 函数，然后在每个函数中分别定义了内联：

inlines = (FashionModelPhotoInline, FashionExperienceInline)

似乎有效。感谢所有看过此内容的人。
