我正在尝试在django Admin中自定义多个内联,但我无法显示基础模型的字段。
这是一个简化的例子。也许你可以告诉我如何引用它们?
以下是我的模特:
class Clown(models.Model):
name = models.CharField(max_length=255)
def edit_link(self):
return ...
class Circus(models.Model):
clowns = models.ManyToManyField(Clown, blank=True, through='WorkedAt')
name = models.CharField(max_length=255)
class WorkedAt(models.Model):
clown = models.ForeignKey(Clown)
circus = models.ForeignKey(Circus)
和我的管理员:
class ClownInline(admin.TabularInline):
model = WorkedAt
fields = ['clown__name','clown__edit_link']
class CircusAdmin(admin.ModelAdmin):
inlines = [
ClownInline,
]
exclude = ('clowns',)
但是我收到了这个错误:
Unknown field(s) (clown__name) specified for WorkedAt
(我在Django 1.6上)
更新 为什么这也不行。 (通过模型添加计算字段。)
class Clown(models.Model):
name = models.CharField(max_length=255)
def edit_link(self):
return ...
class Circus(models.Model):
clowns = models.ManyToManyField(Clown, blank=True, through='WorkedAt')
name = models.CharField(max_length=255)
class WorkedAt(models.Model):
clown = models.ForeignKey(Clown)
circus = models.ForeignKey(Circus)
@property
def edit_link(self):
return self.clown.edit_link()
和我的管理员:
class ClownInline(admin.TabularInline):
model = WorkedAt
fields = ['edit_link']
class CircusAdmin(admin.ModelAdmin):
inlines = [
ClownInline,
]
exclude = ('clowns',)
答案 0 :(得分:3)
试试这个。希望它能解决你的问题
class ClownInline(admin.TabularInline):
model = WorkedAt
fields = ['clown_name', 'clown_edit_link']
readonly_fields = ['clown_name', 'clown_edit_link']
def clown_name(self, instance):
return instance.clown.name
clown_name.short_description = 'clow name'
def clown_edit_link(self, instance):
url = reverse("admin:%s_%s_change" % (instance.clown._meta.app_label, instance.clown._meta.module_name), args=(instance.clown.pk,))
return '<a href="%s">%s</a>' % (url, instance.clown.name)
clown_edit_link.allow_tags = True
class CircusAdmin(admin.ModelAdmin):
inlines = [
ClownInline,
]
exclude = ('clowns',)

我不知道是否还有人需要这个,因为这个问题已经有4年了,但这解决了我在Django 2.0.3
的问题:
# models.py
class Clown(models.Model):
name = models.CharField(max_length=255)
def edit_link(self):
return ...
class Circus(models.Model):
clowns = models.ManyToManyField(Clown, blank=True, through='WorkedAt')
name = models.CharField(max_length=255)
class WorkedAt(models.Model):
clown = models.ForeignKey(Clown)
circus = models.ForeignKey(Circus)
# admin.py
class WorkedAtInline(admin.TabularInline):
model = WorkedAt
extra = 1
class WorkedAtAdmin(admin.ModelAdmin):
inlines = (WorkedAtInline,)
admin.site.register(Clown, WorkedAtAdmin)
希望这可以帮助任何偶然发现这个问题的人并研究这个答案。
